Executive Summary
Millat Group is Pakistan’s leading engineering concern in automobile sector & has a history that
spans almost half a century. MillatTractors Limited MTL is market leading industry of
agricultural tractors & holds above 50% market share. We carried our work according to the
given schedule. The activities assigned to us were very precise and intellectually challenging.
The activities include are; complete visit to market and dealership network to know about the
market policy of MTL, the current demand of tractors & market position of MTL, after sales
services provided to the customers, visit dealer’s workshop to know about the quality of the
Product. Viewing of machining of different parts, Engine assembly, Tractor assembly and
different operations after which the real product comes out. The course of action adopted to
complete these activities was to first understand the Assembly machines and then the assembly
of the parts .These activities were done in the supervision of the assigned engineers. Our activity
also includes to keep an eye on how QA dept. is working and how this dept. make it possible the
best quality product. The response we got from market dealers about the quality of the product is
fairly satisfactory. We also conducted many survey in different departments during our
internship at MTL regarding material flow, health and safety conditions and mishandling of tools
and parts. According to our observation and analysis the reason behind the poor quality of the
product is due to the poor materials supplied by the vendors and inefficiency of QA dept. We
found that customer’s perception about MASSEY FERGUSON is good and irrespective of the
quality customer is always willing to purchase MASSEY FERGUSON. Currently, high price is
the major factor for decrease in the tractors demand. As Pakistan is an agriculture country, Govt.
should implement such policies in agriculture sector that favors farmer. Govt. should right off the
tax on tractor on immediate basis in order to provide support to this falling sector.

3. History
Millat Tractors Limited (MTL) was established in 1964 to introduce and market Massey
Ferguson (MF) Tractors in Pakistan. An assembly plant was set up in 1967 to assemble tractors
imported in semi-knocked down (SKD) condition.
The company was nationalized under Economic Reforms Order in 1972 and started assembling
and marketing tractors on behalf of Pakistan Tractor Corporation (PTC) which was formed by
the Government for import of tractors in SKD condition. In 1980 the Government decided on
indigenization of the tractors and entrusted this task to PTC (Pakistan Tractor Corporation).
PTC transferred this role of indigenization in 1981 to MTL. This was the turning point in the
Company’s history and it went about the task methodically and rapidly. The Company undertook
this new role with enthusiasm and in the spirit of national development and proved its
engineering capabilities by surprising the deletion targets set by the Government. Just in one
year’s time, the company took a giant step towards self-reliance by setting up the first engine
assembly plant in Pakistan.
In 1992, the company was privatized. The employees joined hands and took over the
management by winning an open bid.
To maintain its leadership role in tractor manufacturing in the country, MTL continues to look
toward future, to identify and exploit new opportunities and to consolidate existing ones. The
Tractor Assembly Plant is part of this philosophy. This plant started its production in 1992. The
establishment of this modern plant not only increased production capacity to 16000 tractors per
year on a single shift basis, but also provided a quantum jump to the quality of the assembled
tractors and pushed MTL into ranks of the major tractor manufacturing companies of the World.
The Company made a strategic decision right in the beginning to bring those manufacturing
facilities in-house for which capabilities did not exist in the country and for parts which required
high precision and investment. Therefore, in 1984, sophisticated manufacturing facilities for the
machining of intricate components were set up. These were previously not available in Pakistan.
Currently, critical components like Engine Blocks, Sump, Transmission Case, Axle Housing,
University of Agriculture Faisalabad
Page 13
14. Millat Tractors Limited
Hydraulic Lift Cover, Front Axle Support and Centre Housing are all being machined most
successfully in-house at MTL from locally sourced castings.
At MTL, we firmly believe that producing to International quality standards is the key to our
continued success and growth, and our quality control department converts this belief into
reality.
In 1992, the company was privatized. The employees joined hands and took over the
management by winning an open bid. To maintain its leadership role in tractor manufacturing in
the country, MTL continues to look toward future, to identify and exploit new opportunities and
to consolidate existing ones. The Tractor Assembly Plant is part of this philosophy. This plant
started its production in 1992. The establishment of this modern plant not only increased
production capacity to 16000 tractors per year on a single shift basis, but also provided a
quantum jump to the quality of the assembled tractors and pushed MTL into ranks of the major
tractor manufacturing companies of the World.
After successful takeover, MTL also acquired the management control of Bolan Castings
Limited (a Public Limited Company specializing in intricate automotive castings) in partnership
with employees of the company, in 1993.
In 1992, the production of Millat Tractors was just 8,000 units per annum with variety of only 2
main products, now the annual production is reached from 8,000 units to 45,000 units with
variety of 8-different main models. Moreover, the company looks to the future with optimism
and plans to broaden its customer base. Consequently the opportunities are being explored in
multi-application of engines and tractors in areas other than farming sectors. Mass Production of
Generating Sets was started in 1994, while a 3-Ton Fork Lift Truck branded as Millat, based on
TCM technology was launched in the year 2002.
In addition, Millat Tractors Limited has been the regular recipient of the Corporate Excellence
Award of Management Association of Pakistan and the Top Companies Award of Karachi Stock
Exchange, since early eighties. MTL’s Annual Report has been acknowledged as the Best
Annual Report by the Institute of Chartered Secretaries and Admin Association of Pakistan for
several years.

5.2. Internship Activities of 1st and 2nd week
5.2.1. Day 1Activity
On day 1 (01-04-2013)as per schedule we had avisit to Engine Assembly Plant where we
reported to Mr. Abdul Mannan. He briefed us all the engine assembling stages & engine testing
system. We spent full day over there & observed things closely. Firstly we went to segregation
section where all parts are received. After that these parts go through the process of De-greasing
(Trichloroethylene) & Washing (Redline). Then we moved to main assembly line where all the
parts are assembled on its turn as given in Engine Build/Test Card. The workers were doing
necessary quality checks where required. When the engine was completely assembled it was
ready for test run. In engine testing section the engine was attached to the testing machine for a
duration of 40min. The engine was tested against the different rpm & loads. The pressure in the
oil galleries was tested by a software operated testing machine. If the engine passes the test it is
ready to go to the Tractor Assembly Plant.
5.2.2. Day 2 Activity
On day 2 (02-04-2013) as per schedule we had a visit to Tractor Assembly Plant where we
reported to Mr. Khurram A Warraich. He brieflydescribes all the operations happening in Tractor
Assembly Plant&also told us that the Plant is ISO certified. During this brief introduction we
came to know the production capacity of the plant which is normally 58 tractors per shift. There
are 2 shifts per day & one shift can produce max of 97 tractors. Around 112 persons work there
in 1 shift. There are 3 assembly lines (Rear Axle Build line, Chassis Paint Line, Final Build
Line).We closely observed all the assembling stations turn by turn.Whenever we found it
difficult we consulted with the station supervisor. When the tractor is fully assembled it is passed
to QA. Then the QA issues the fitness certificate to that tractor & if it does not match the
standards it is sent back to remove the fault. If it clears all the required tests it is further passed to
marketing department.
5.2.3. Day 3 Activity
On third day (03-04-2013) we visited the Sheikhupura and Ferozewala dealers and their
workshops. Our major concern was to know about the market share of MTL and its competitors,
quality of the brand, dealership network and commissions. In these regions MTL occupied the
maximum market and the share is about 100%. The dealership network is very extensive to
facilitate the farmer at his doorstep and workshops are available at every 10 km distance. From
today’s visit we concluded some points that are listed below.
According to the dealers, the overall quality of the tractors is not satisfactory because of the
reasons like the performance of Fuel Injection Pump is not good as it consumes more fuel due to
University of Agriculture Faisalabad
Page 31
32. Millat Tractors Limited
the greater rotor clearance. The major problem is of Differential System (Crown Wheel).There is
also a problem of Rear Rim distortion in shape and early rusting of the rims.Pressure is not
maintained in the Hydraulic System under loaded conditions due to the manufacturing fault.The
chassis is not properly painted due to which sometimes it rusts. We collected this information by
visiting the dealer’s workshop by interviewing the fore-man there on duty.
5.2.4. Day 4 Activity
On 4th day (04-04-2013) we dealt with after sales services regarding warranty and its terms and
conditions,claim details, IFS software, rejection section and material management
department.Warranty of tractor is 1 year or 1200 hours from the date of delivery. Accidental case
is not accommodated. Parts can be claimed from nearby dealer’s workshop. Within first 24 hours
any problem in engine the whole tractor is replaced. Within 100 hours any problem in engine the

Cylinder block
It is foundation of the engine. All other engine
parts are assembled in or attached to cylinder
block. There are two cylinder block machining
lines.
Old Manual machining line
New Automatic machining line
Old Machining line
Capacity of old line is 48 parts per shift. It uses
casted cylinder blocks from Karachi and machines
them through a number of operations. These
include
Drilling, boring and reaming holes for attaching various parts such as crank and cam
bores, water jacket holes etc
Cylinder bores are machined and then provided surface through process of honing.
Since overhead camshafts are used in the engines manufactured here, camshaft bearings
holes are bored.
Surfaces to which parts are attached are milled, machined and surface finished.
Oil passages are drilled.
Coolant passages are cleaned out.
Then all seal plugs are fixed and then the cylinder block is tested for any leakages
through pressure test. There is an automatic hooter attached with the test bench. If the
pressure drops inside the submerged cylinder block, it indicates a leakage and
automatically buzzer starts sounding.
Engine cylinder liners are then fitted inside the cylinder. They save the cylinder walls
from getting damaged due to continuous reciprocating motion of piston against cylinder
wall.
Cylinder liners are again bored and honed for smooth and accurate surface finish.
New Automatic Machining line
It has got a capacity of 72 parts per shift which is quite faster than the old machining line as it
uses different transfer systems that perform different machining operations in a single plant thus
decreasing the cycle time and increasing productivity. Cast iron blocks used here are casted in
china.
All the 22 operations performed are same as old line but in different sequence. Different plants
and machines used in this process are

Transmission Case Machining Line
Transmission case is a very important
component of a tractor and it has got one
semi‐automatic line. That line had been shut down for
some maintenance work so the 3 CNC i.e.
computerized numerical control machines were being
used for its production.
CNC machines were being operated by
specialized operators who would enter a part program
into the machine and then close the door for CNC to
work. At a time, 3 components could be loaded into
the CNC machine which would be machined one after
the other.After machining the total weight is 77.8 Kg

Cylinder head
Cylinder heads machined here are first casted
out of Cast Iron for 3 cylinder engines. They
are machined to take various parts that are
attached or installed in the head such as valves.
Cylinder head forms the top of the combustion
chamber while piston and ring form the
bottom. Then they are bought in this plant to be
accurately machined to be used in the engine
assembly. There is one machining line for
cylinder heads and its capacity is 90
components per day shift.
After machining, the final weight of cylinder head is 25kg and it’s a grade 17 with hardness
of179‐235 BHN. There are 2 transfer systems in cylinder head machining line. Cooling jackets,
intake & exhaust manifolds are casted inside the cylinder head.
Exhaust Manifold
It is a set of tubes. It carries exhaust gas from cylinder head to the exhaust system. The manifold
attaches to the head so the exhaust ports in head align with the tube openings. An in‐line engine
has 1 exhaust manifold.
Inlet manifold
It is set of tubes that carry air or air‐fuel mixture from throttle valves to the intake ports in the
cylinder head. On in‐line engines, the intake manifold attaches to the side of cylinder head. At
the start of the machining operations casted parts are fed into a PLC operated transfer system
where milling, drilling and taping of cover plate occurs. Then it is fed into 2nd plant which is
also PLC operated where cover plate is drilled and reamed. Also, inlet and exhaustmanifold
milling occurs here and it takes 3 min times approximately. The parts are then fed into an RLC
University of Agriculture Faisalabad
Page 45
46. Millat Tractors Limited
based transfer system where operations like drilling, counter boring, taping, reaming and
sub‐drilling occurs. Then valve seats are accurately machined so that valves accurately fit in
them. Inlet hole is larger than exhaust hole to make more air come into the cylinder for
combustion.

Vapor degreasing is a surface finishing process. It involves solvents in vapor form to cleanse the
workpiece in preparation for further finishing operations.
The acting principle behind the vapor degreaser process is that the solvents will dissolve the
contaminants on the workpiece and remove them by dripping off the part. A basin of solvent is
set up with a heating coil to bring the solvent to boil. As the solvent evaporates it rises to the
fill‐line in the chamber, above this is air with a much lower density than the solvent. This
contains the vaporized solvent in a closed space where the workpiece is placed.
The solvent condenses on the more frigid workpiece and the now liquid solvent dissolves the
greases on the part. With the impurities contained in the liquid beads, the solvent runs off the
part. Some systems are designed to capture and reclaim this solvent, making the process much
more economical.

Whenever we faced any problem regarding any part or operation, we asked supervisor there, he
guide us properly and is always willing to help us. We observed the things and collected helpful
information by interviewing the staff at Engine Assembly Plant.
Each engine when assembled is tested for set duration of time in Engine Test Section on Test
Bed. There are 12 Test Beds in Engine Test Shop. Engine is attached on the Test Bed and
different load is applied for different interval.

If the engine fulfills the quality standards, it is ready to go to Tractor Assembly Plant but if it
fails it is sent to Rectification Section. QA dept. in Engine Assembly Plant is working efficiently
to maintain the quality of the product in order not to letdown the MTL.
There is a complete testing setup for every engine that comes out of the main assembly line.Here
engine is thoroughly checked for its working and any possible faults such as enginenoise, rpm,
loading, leakages, exhaust smoke etc.In engine build card different performance factors of every
engine are entered after testingand if there is an error found then engine is referred to the
rectification section.

Tractor Assembly Plant(TAP)
This is the main plant of Millat Tractors. All the components of tractor carried from different
locations are assembled here.In this plant all the parts of thetractor are assembled in assembly
lines. We worked as interns here for five days. Productioncapacity of 3 cylindersis 59 tractors
per shift and for 4 cylindersit is 36 tractors per shift.They work in double shift.
10.1. Tractor Assembly Shop
Start from axle assembly on one side and receive a computer tractor from the other side. The
whole assembly process is manual. The process can be categorized in seven stages narrated
below
1. Axle assembly
2. Plough assembly

Final stage
1) Axle Assembly
This is the first stage in tractor assembly. There are two axle assembly lines, one for right axle
and other for left axle. Axle is fitted in axle tube which is followed by brake assembly. On week
end of the axle roller bearing is placed. The further operation on axle assembly line is the fixing
of left and right axels with center housing.
Centre housing is one of the main components of the tractor. Mainly it comprises of crown wheel
and pinion mechanism, six different gears, hydraulic pump and power transmission shaft.
2) Plough Assembly
It contains hydraulic cylinder, piston and plunger assembly. Cylinder contains hole in its bottom,
through which the pressurized oil from the hydraulic pump enters which operates the plunger
assembly which governs the rise and fall of plough. The pressure of the hydraulic pump is
variable and its control is provided with two levers through which the rising and falling speed of
plough is controlled.
3) Plough testing plant
Perfection of plough assembly is must. As plough is one of the main functions of the tractor. So
its correctness is checked immediately after its fitting. The known weight which, is decided by
considering factor of safety, is being lifted by this. The oil leakage and the correct rotation of
PTO shaft is also checked here. If it is working well then it is sent for further operations
otherwise rectif8cation is done on finding a fault.
4) Gear box Assembly
The gearing of the tractor is controlled through gear box, it is a bit complicated and contains
many gear trains placed in the gear box housing. After gear attachment, levers for the gear
alteration are fixed on the position provided at the top of the gear housing.
5) Attachment of Engine
The most important part “the engine” of the tractor is attached here. Engine is attached and the
contacts are provided to the gear box
6) Washing and Painting Plant
More than fifty percent completion of the task is done up till now. Here the main body of the
tractor is washed for the removal of any dust particles or other contaminants attached during
University of Agriculture Faisalabad
Page 72
73. Millat Tractors Limited
previous stages. This is followed by drawing of this assembly, which is followed by the coating
of this assembly with paint.
7) Final Stage
Now the final touch is given to the tractor assembly which comprises of the wiring, attachment
of head light, seat, safety covers, fuel tank, radiator, battery etc
8) Pre-delivery Testing
Now the tractor is ready for trial run, after having trial run, any fault e.g. leakage of oil, missing
of any nut or bolt, tightening of nut or bolt etc is identified and rectified.
NOW THE TRACTOR IS READY TO SEND TO THE MARKETING DIVISION
Bevel Gear
Bevel gears are gears where the axes of the two shafts intersect and the tooth-bearing faces of the
gears themselves are conically shaped. Bevel gears are most often mounted on shafts that are 90
degrees apart, but can be designed to work at other angles as well. The pitch surface of bevel
gears is a cone.
Power Take-Off Systems and Hydraulics
In addition to towing an implement or supplying tractive power through the wheels, most tractors
have a means to transfer power to another machine such as a baler, swathe or mower. Unless it
functions solely by pulling it through or over the ground, a towed implement needs its own
power source or else a means of transmitting power from the tractor to the mechanical operations
of the equipment.
Early tractors used belts or cables wrapped around the flywheel or a separate belt pulley to power
stationary equipment, such as a threshing machine, buzz saw, silage blower, or stationary baler.
In most cases, it was not practical for the tractor and equipment to move with a flexible belt or
cable between them, so this system necessitated that the tractor remain in one location with the
work brought to the equipment, or that the tractor be relocated at each turn and the power set-up
reapplied.
Modern tractors use a power take-off (PTO) shaft to provide rotary power to machinery that
may be stationary or pulled. The PTO shaft generally is at the rear of the tractor, and can be
connected to an implement that is either towed by a drawbar or a three-point hitch. This
eliminates the need for a separate implement-mounted power source, which is almost never seen
in modern farm equipment.
Virtually all modern tractors can also provide external hydraulic fluid and electrical power to the
equipment they are towing, either by hoses or wires.

Transmission (Mechanics)
A transmission or gearbox provides speed and torque conversions from a rotating power source
to another device using gear ratios. In British English the term transmission refers to the whole
drive train, including gearbox, clutch, prop shaft (for rear-wheel drive), differential and final
drive shafts. The most common use is in motor vehicles, where the transmission adapts the
output of the internal combustion engine to the drive wheels. Such engines need to operate at a
relatively high rotational speed, which is inappropriate for starting, stopping, and slower travel.
The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in
the process. Transmissions are also used on pedal bicycles, fixed machines, and anywhere else
rotational speed and torque needs to be adapted.
There are two types of gearing systems, Manual and Automatic.
Manual Transmission
Manual transmission comes in two basic types:
1. a simple but rugged sliding-mesh or unsynchronized / non-synchronous system, where
straight-cut spur gear sets are spinning freely, and must be synchronized by the operator
matching engine revs to road speed, to avoid noisy and damaging "gear clash",
2. and the now common constant-mesh gearboxes which can include non-synchronized, or
synchronized / synchromesh systems, where diagonal cut helical (and sometimes doublehelical) gear sets are constantly "meshed" together, and a dog clutch is used for changing
gears. On synchromesh boxes, friction cones or "synch-rings" are used in addition to the dog
clutch.
Automatic Transmission
Epicyclical gears or Planetary gears as used in an Automatic Transmission.
They primarily use hydraulics to select gears, depending on pressure exerted by fluid within the
transmission assembly. Rather than using a clutch to engage the transmission, a fluid flywheel,
or torque converter is placed in between the engine and transmission. It is possible for the driver
to control the number of gears in use or select reverse, though precise control of which gear is in
use may or may not be possible. Automatic transmissions are easy to use.
10.2. Sections of TAP
This will define the different processes being held in different sections of TAP.This is the most
important plant of the tractor industry. There are four important sections of tractor production.
These are as follows:
Segregation and Degreasing
Assembly line
Sheet Metal Washing and Paint Shop
Test shop/Rectification area
University of Agriculture Faisalabad
Page 74
75. Millat Tractors Limited
1) Segregation and Degreasing
In this section, components of tractor are counted and supplied to all stages of productionin racks
through trolleys and folk lifters etc. Components are vapor degreased here by 80 degree
University of Agriculture Faisalabad
Page 75
76. Millat Tractors Limited
centigrade of water and by blowing of air. Cleaning, packing and opening ofwrappers of
components are done here.
2) Assembly line
After segregation and degreasing of components, they are distributed to the assembly line. There
are 10 stages in assembly line as op 10‐100. But we will discuss only the major three stages
ofassembling and paint of our concern product i.e. Tractor.
a) Rear axle build
b) Chassis build
c) Final build
a) Rear axle build
In rear Axle building of a tractor there are five main assembling are being done. Theseinclude
crown wheel assembly, center housing assembly; axle housing assembly; axle shaft assembly
and hydraulic lift cover assembly.
• In crown wheel assy. Crown wheel and pinion both are assembled and torque by workers and
are passed to the center housing section by roller conveyors. Preloading test of pinion is done
here in this section. Two presses are used here for press fitting.
• In center housing assy. Pinion and crown wheel are assembled by hammering and nut bolt.
PTO shaft is assembled and fitted in center housing. Two plates named cover plate and response
plate are attached to the left and right of center housing. And then hydraulic pump and coupler
gears for running PTO shaft are assembled in it.
• In axle housing assy. Both left and right housing are assembled. Left and right differ from
each other in a sense that right one has differential paddle attached to it. And left one is simpler
in assembling than right axle housing. Here brake shoes are assembled and attached. Lather
brake is for MF240, manual disc brake is for MF260 and MF350. While hydraulic disc brakes
are for MF375, MF385 and MF385 4WD. In hydraulic brakes, reduction units are used. And
then complete housing is passed to the conveyor.
• Axle shaft is assembled then to attach both axle housings.
• In hydraulic lift cover assy. It is assembled to the top of axle housing.
Hydraulic System Test Rig
Hydraulic lift cover is then checked at this section to ensure that all the lifting components are
working correctly.
b) Chassis build
After the rear assembly is mounted on trolley, chassis building is started. It includes assembling
and testing of many important components of tractor. Its stages include Gear box assembly,
Steering assembly, Transmission assembly, Engine assembly, Foot board assembly, Brake

paddle assembly, Front support assembly, Fuel tank bracket assembly and Link and York
assembly. These all are done on moving conveyor which have 10 tractors per hour.
In Steering assembly, first of all steering is assembled. Manual steering is for MF240
and MF260 and Hydraulic steering is for MF350, MF375 and MF385 model.
In Link and York assembly, links and York’s are attached to the chassis.
In Gear box assembly, 8 gears including forward and 2 reverse gears are assembled. In
tractors crush gearbox is used. Gear box is also tested here.
In Transmission assembly, assembled gear box is fixed inside it. Both PTO shaft and lay
shaft are attached on front and back sides of transmission case.
In Engine assembly, first of all engine is prepared in sub‐assembly where PTO plate,
clutch plate and input plate are attached to the engine. And then engine is fixed to the
chassis.
In Foot board assembly, assembled brake paddle and foot board are attached.
University of Agriculture Faisalabad
Page 77
78. Millat Tractors Limited
In Front support assembly, complete and assembled front support from sub assembly is
brought and is attached to the front portion of the chassis. After chassis assembly is done,
whole chassis is sent to the gray paint shop, where at high temperature of water chassis
body is rinsed and degreased in booth # 1 and then is warm air dried, and then is gray
painted. And it is then sent to the oven for further drying and phosphating.
Pressure plate and clutch plate are bolted in the flywheel of the engine. Transmission case and
engine are attached to the center housing on the moving DOCK. Then front support,footboard,
steering,brake paddles and brackets for fuel tank are attached.
c) Final build
The complete chassis is now ready for the final build assembly in line 3. Here many important
components are assembled and then the complete tractor is ready for further testing and
rectification if necessary.The final major components of tractors include radiator, fuel tank,
wiring, seat assembly, lower link chain, bulk head, dash board, accelerator, battery, wrapper,
hood top, steering, fender, front grill, front tire and rear tire
.
Radiatorfor 240, 260 and 385 are all different and is assembled by nut and bolt in the
first stage of assembling in line 3.
Fuel tankfor 240, 260 and 350 are same and made up of steel with a capacity of 48‐ 50
liters. And the fuel tank for 375, 385 and 385 4WD is made up of plastic or ABS material
with a capacity of about 75‐85 liters.
Wiringis completed here. It is of three types that are main harness, back to front and
front to back.
Seat assemblyis completed is sub assembly and is ready to be fixed. Seat is same for all
models.
Lower link chain is assembled then. It is of golden color, is used to prevent unnecessary
movement and maintains level.
Bulk head is that where dash board is attached. Brakes, clutches, master cylinder,
steering pump and orbital unit are all placed inside it. It is for big tractors.
Dash board is assembled then. It is different for 240,260 and 350. Tachometer, hour
meter, rpm meter indicator lights and neutral lights are all attached to it. It shows no
mileage as in cars.
Both hand and foot accelerators are attached in this stage.
Battery is same for all tractors. Vaseline is used for assembling. In low power engines
battery is attached in the front of the tractors. And for high power it is mounted below the
foot board.
Wrapper is of silver color. It is same for 240 and 260, but different for other models.
Hood top is different for all models
Then steering is assembled.
University of Agriculture Faisalabad

79. Millat Tractors Limited
Fender from paint shop is fixed. Bracket is different for all models.
Front grill is attached. It is for air intake.
Rear tire has got treads. Tire size is different for different models.
Front tire has got grooves on it
.
All the listed components are attached one by one to the recently painted and baked portion of
the tractor. Meanwhile wrapping section attaches the MTL monogrammed sticker to the
Hoods.Big tractors MF-375 is filled with 37litres of Mobil oil while small unit i.e. MF-240 are
filled with 32litres. 9 liters of diesel is also pump into their tanks.
3) Sheet Metal Washing and Paint Shop
Chassis paint shop contains three sub sections.
1. Grey paint on chassis
2. Red/green color coating
3. Heating oven
The chassis is first painted manually after sealing the necessary holes and screws. In other
sections, Red/Green color is painted after degreasing the sheet metal from the inventory.
Degreasing and primer coating is done automatically. Then both, chassis and sheet metal parts
are brought into heating oven to let them dry.
During its assembling in line 3, there is a sub assembly for painting metal body of tractor. It is
called red oxide metal paint shop. Here the metal sheets are moved on conveyors by hangers.
First they are washed, dried at high temperature and then is manually gray painted, then is sent to
the oven for phosphating and drying, then it is painted red oxide from one side, and then again
dried in oven and this process goes on till we receive clear red oxide color of sheet from both
sides.
4) Test Shop/ Rectification Area
This section checks the recently manufactured tractors for the very first time. Technicians test
drives each one of the tractor to ensure the proper working of each component. If any minor
trouble is found, skillful workers take it into notice right on the place. For major problems tractor
is sent to another section.In this area tractor is thoroughly checked and tested. The entire nuts,
bolts, gauges, meters, oil and fuel lines are checked. Roller machine test is done for 10 minutes
to check the tractor on high RPM and to check any leakage and brakes are adjusted.
After maintenance,tractors are also sent to road tests.
Touch Up Paint Booth
If paint is missing on any of the components, it is repainted in touch up paint section.
University of Agriculture Faisalabad

Pre-Delivery Inspection(PDI)
PDI and segregation are not considered the part of TAP but they are former and later stages of
TAP.This is basically the job of marketing department. Before handing over the tractor to its
owner, it is assured that it is functioning properly and having no problem. This department again
performs total checkup of tractor and if there is any fault then it is sent to major rectification
department.
After minor and major rectification and also after passing the paint n retouching section, pre
delivery inspection is done on the tractor in a PDI dept. If tractor has passed all the sections then

11.1. Task 1
To know about the mishandling in different sections of TAP and to analyze
the reason behind that
11.1.1.Introduction
Mishandling is a very big issue in any industry and its cost is always beard by the industry thus
the profitability is decreased. Mishandling can be narrated as the miss use of the tool or the miss
use of the component to be assembled both are under the issue of mishandling. Millat lost 2.5
million as mishandling expenses in Tractor Assembly Plant only which is a big loss.
We the internees were asked to conduct the survey in Tractor Assembly Plant on
Mishandling. Our main concern was to know about three main questions and to help understand
the reasons and to give suggestions to limit the mishandling losses.
Q.No.1. Do the worker know about what is mishandling?
Q.No.2. Why mishandling occurs?
Q.No.3. Suggestions by the workers i.e. how we can minimize this mishandling.
On our first day, we went to Tractor Assembly Plant where we were asked to conduct a
survey on mishandling. We were advised by Mr. Akmal i.e. how we can conduct a survey and
what questions we should ask to the workers. We went to the workers and asked them the
questions. As a matter of fact 40% of the workers even don’t know about the concept of
mishandling, as our moral duty we told them that what is mishandling in actual.
11.1.2.Detailed Data of Mishandling
The below given data will help in understanding the current status of the workers on
mishandling. This will show that either the worker understands mishandling or not and some of
the major reasons of mishandlings like the roll of expert or newly appointed worker in
mishandling, either the correct way of rejection is adopted or not, inspector sincere to MTL or
not i.e. the part that should go to the vendor due to manufacturing mistake is debited to vendor or
MTL by showing mishandling case, mishandling due to press machine malfunctioning and either
the inspector is available on the line all the time or not. So this all data is tabulated below.

Data of Mishandling Survey
11.1.3.Reasons of Mishandling
The following are the main reasons of mishandling.
1. Above all the reasons one thing in common was that newly appointed worker always do
losses as he is unfamiliar with the system, so less expertise of the laborer is the main
reason in mishandling. We also came to know that some appointments of workers on
reference are not right some of those workers are not fit for the job hence they greatly
mishandle tools and components as they are not eligible.
2. QA should not allow the bad quality piece fed to assembly line, once it is assembled it
becomes mishandled willingly or unwillingly.
3. Due to over burden of production mishandling occurs.
University of Agriculture Faisalabad
Page 82
83. Millat Tractors Limited
4. Duties changing again and again cause mishandling as every worker best knows his
work.
5. While making fun at working time, sometime tools become the part of their fun.
6. It occurs due to low quality of tools used.
7. By the worker i.e. use of improper tool for specific function.
8. By the negligence of the worker like sometimes the threads of the nut and bolt mismatch
and it is tightened so both the parts become waste.
9. Millat Tractors Limited purchases low quality parts which breaks during working so it
also becomes the case of mishandling.
11.2. Task 2:
To know about the material flow through different sections of TAP and
analyze problems regarding material flow
11.2.1.Introduction:
On day 2 (07/05/2013), we reported to Muhammad Akmal Dy. Manager (TAP). He gave us a
brief description about the productivity of the plant. The overall productivity of the plant
depends on both input resources and output of the plant. The productivity can be increased either
by increasing the output or decreasing the input resources. Input resources includes
Man
Material
Machine
Tools & Equipment
Method
We have already completed our task related to MAN input on day 1. On 2nd day, we were given
a task on material input. As per given instructions we prepared 2 questionnaire. 1 for segregation
section and the other 1 was for plant. We made two groups consisting 3 members each.1st group
went to segregation dept. and 2nd was on Assembly lines. We interviewed some of the workers
and supervisors there. They responded to our questionnaire to the level of their knowledge. The
questionnaires are given below.

Remarks:
Storage Bins are not enough in every section. Some line facing severe shortage of bins.
Due to this, parts are placed on the floor that results in Mishandling of parts
For higher productivity, the number of bins should be increased. This will reduce
Mishandling and time of production.
Q.2.

Remarks:
Workers from Segregation section just throw the parts in the bins that might results in
damage of some parts. This results in poor production cost.
Authorities should consider this factor seriously and proper training should be given to
worker to avoid mishandling

Remarks:
Workers from segregation section don’t drop or deliver the parts to each station. They
just throw in into the Storage bins.
Shortage of fork lifters or stillage forces the workers to do their work quickly in order to
keep the production running.
In addition, training should also be given to the workers to avoid mishandling of the
parts.
Q.6. Are the parts delivered to stations on time? If not, then what are the reasons for
delay?
Worker

Remarks:
Remarks
Yes
Yes
Yes
Yes
Usually it doesn’t happen but sometimes it does happen. The main reason for this is
Shortage of Fork lifter and Stillage. The production rate is very fast, for this material flow
should also be fast but the quantity of fork lifters and stillage doesn’t respond to the number
of work stations.
Shortage of racks is also another factor for the delay of parts. Station having only one rack
of each part suffers the most. When the rack is emptied, then parts will be delivered by
taking the rack to the segregation section. A lot of time is consumed in moving the racks
that slows down production.
