A 'How to' presentation by Forza Components (www.forzacomponents.com) describing how to remove and replace a Ferrari Testarossa (+512TR & 512M) clutch thrust race, also known as the throw out bearing

1. Testarossa
Clutch Thrust Race
Also know as the ‘throw out bearing’

2. Tools required
•
Nothing other than standard workshop
tools
•
Copper grease
•
‘O’ ring grease
•
Brake / clutch fluid.

3. Based on:
•
1987 Testarossa
•
Euro Model
•
F113B
•
Tubi Sports Exhaust

4. •
Remove the four10mm nuts holding the
air inlet and heat cover

5. •
Remove the two large screw clips that
connect the air filter box to the large
rubber hoses
•
Disconnect the cloth covered oil tank
breather hose

6. •
Slacken the 10mm nuts holding the air
filter box to the left and right plenums.
•
Remove the whole air filter box and
heat shield, we can now get the clutch
housing.
•
Be careful with the heat shield, it is an
asbestos sandwich.

7. •
Remove the clutch hydraulic lines from
the clutch housing and cap off the hose.

8. •
Remove the stainless steel heat shield
from the rear of the clutch housing.
Three 10mm nuts.

9. •
Remove the exhausts so that there is
space to the rear of the clutch housing.
Mine looks like this when the Tubi is
removed.

10. •
Drain the oil from the Transmission
housing (NOT the main gearbox) There
should be only approximately 1/2 pint of
oil in the transmission.

11. •
This is a view of the clutch housing and
transmission with the engine out of the car.
Remove all the 13mm nuts and bolts on the
periphery, don't forget the one hiding
underneath.

12. •
Using a rubber mallet, give the clutch
housing a loosening tap to release the
seal.
•
Pull the clutch and transmission
rearwards to remove.
•
The unit is quite heavy so be prepared
to take the weight once it is released. I
always remove the rear bumper and
lower valance to help but its up to you.
•
Don't loose the two ‘O’ rings on the
large steel tubes.

13. •
We are in!
•
This is the clutch thrust race sitting on
the engine output shaft.
•
Remove the small circlip and the bearing
should pull free.
•
I took the opportunity to remove the
whole unit for servicing
•
When replacing the housing add a little
copper grease to the shaft.

14. •
Re-build is just the reverse of the
removal.
•
Take note of the torque settings in the
Work Shop Manual (WSM)
•
Get a helper to bleed the clutch
•
Test drive
•
Beer, Job done!
