Crankshaft oil seals

Crankshaft oil seals

Two inner spring rubber oil seals are located, one in a special seat in the timing gear cover and the other in the flywheel end of the crankshaft support and provide oil tightness. These seals are shown in FIGS 1:3 and 1:34. Whenever the engine is dismantled for overhaul these seals should be carefully inspected for correct seating and that the inner seal surface is not worn and that the contact area is perfect both on the crankshaft and on the fan and generator drive pulley hub.

Clutch shaft pilot bushing

A self-lubricating bronze bush is fitted in the end of the crankshaft as shown in FIG 1:34 and provides a bearing for the clutch shaft. Should the bush be worn use Fiat puller A.40006/1 /2 to remove the worn bush. A new bush should be fitted using a suitably sized drift.
