Reduce Aviation Maintanence Costs with oilmatic pre oiler proven to extend aircraft engine life

  1. 1. Reduce Aviation Maintanence Costs With Oilmatic Pre Oiler proven to extend Aircraft Engine Life Oilamatic Pre Oiler Installed on a Cessna T210 Most turbocharger installations also incorporate a scavenge pump to draw the oil from the turbocharger housing. However, when the engine is not running, none of these oppositions to oil leakage exist. To the contrary, the scavenge pump acts as a seal to prevent oil return to the crankcase. Continued preoiling would build pressure in the turbo housing, and oil would be forced out both compressor and turbine seals. Pressure cutoff switches and/or strict limitations on preoiling time must be incorporated to prevent undo leakage from the turbocharger. With these limitations, turbochargers benefit tremendously from preoiling. A preoiler can be used to lubricate an engine without starting. Turn the preoiler on and spin the engine through several turns. Oil will flow to all parts of the engine and the cold thick oil will be slung onto all of the cold metal where it will stay for an extended time. Engines with cylinder lubrication ports in the connecting rods will also have well oiled cylinder walls. Of course, if the preoiler is run for extended time without external power, the battery will need recharging. If the engine is turbocharged, the oil line to the turbo may have to be capped to prevent excess oil leakage from the turbo seals. This is a small chore to insure good lubrication to the rest of the engine.
  2. 2. Oilamatic, Inc. has been developing preoilers for several different engine applications. Recently, they have received FAA STC and PMA approval for preoiler installations on several aircraft. Prices of kits range from $1395.00 to $1545.00 and include all fittings, wire and hardware. Hoses must be procured separately. The Oilamatic engine preoiler unit is a 12 or 24 volt electric motor driven pump. The custom designed and manufactured pump is plumbed into the engine oil system using special adapters so that oil is drawn from the crankcase and injected directly into the engine through the oil filter. The pump and motor are sized to provide adequate preoiling for a cold engine while keeping battery draw to acceptable limits. A check valve in the high pressure side isolates the pump from the engine once the engine is started and the pump is turned off. A dash mounted switch operates the preoiler (with Master switch on). The pilot can monitor preoiling on the engine oil pressure gage and turn the pump off as the starter is engaged. Typical installations provide oil pressure stabilized near the "bottom of the green" before start. No air is left in the system, and all parts are lubricated before their first motion. No matter how long the engine has been sitting, it is fully lubricated before start instead of after. In summary, preoiling an engine can reduce that excess wear attributed to insufficient lubrication during start or from ill affects of long periods without operation. It is most comforting to see the oil pressure gage reading in the "bottom of the green" before the propeller starts turning.
