Crankshaft Front Oil Seal, Gearbox Oil Seal, Crankshaft Oil Seal, crankshaft rear oil seal
Crankshaft seal
The two major seals in your engine are the front and rear end oil
seals, which are located at either end of the crankshaft, and
connect to the flywheel at one end and the fan at the other. They
are also found on, among other places, the valves in the combustion
chamber of your engine.Seals are small but vital for your engine.
The front and rear crankshaft seals are a proper combination of:
Seal + Wear Sleeve. Front and rear crankshaft seals have Wear
Sleeves to provide increased crank reusability. Wear Sleeve
inproves performance of the seal, keeping the dirt away from the
sealing lips; this avoids the contamination of oil, maintaining its
lubrication properties. The Seal has grooves in the seal lip that
return to oil to the deposit during the rotation of the crankshaft.
