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.
