What is the function of the crankshaft front oil seal



The crankshaft front oil seal, also known as the front main seal, serves an important function in an engine. Its primary role is to prevent oil leaks from the front end of the crankshaft. The seal is located at the front of the engine, where the crankshaft extends out from the engine block.

The crankshaft front oil seal creates a tight seal between the stationary engine block and the rotating crankshaft. It prevents engine oil from escaping the crankshaft area and leaking onto other engine components or the ground. By maintaining this seal, the oil is contained within the engine, ensuring proper lubrication of the crankshaft and other crucial engine parts.

A functioning crankshaft front oil seal is vital for the overall performance and longevity of the engine. It helps to preserve the engine's oil supply, prevent oil contamination, reduce friction and wear on the crankshaft, and maintain efficient engine operation.
