Its main function is: Oil sealing: Prevents the engine's internal oil from leaking out from both ends of the crankshaft. Dust prevention: Preventing external contaminants such as dust, sand, and moisture from entering the engine interior. While the crankshaft is rotating at high speed, it also has a slight radial movement of its own. Therefore, the crankshaft oil seal needs to maintain excellent sealing performance under such dynamic conditions for a long time. 237.250 Rear Crankshaft Oil Seal For 1052B219 Mitsubishi Colt Lancer Working principle Its sealing principle is also a fluid dynamic seal. The contact area between the lip and the rotating crankshaft surface forms a very thin lubricating oil film. The return oil lines on the lip (usually spiral lines) generate a strong "suction effect" when the crankshaft rotates, pumping the oil that is attempting to leak out back into the engine interior, thus achieving a dynamic balance state of "no oil leakage".
