Crankshaft lip seal

Shaft seal rings ensure the tightness between the crankshaft and the engine block.

When should you change the gasket?

The seal whatsoever, is essential for proper engine operation. A leak can quickly cause damage to adjacent pieces. For example, the gasket on the side of the clutch, in the long term, lead to malfunction.

• As part of a revision, it is possible to find traces of oils or other liquids. This is usually due to poor sealing and the need to change the seal.
• In a major operation requiring disassembling the engine, it may be wise to take this opportunity to change the corresponding seals.

How to replace a shaft seal ring

• Once the seal available, remove the old gasket, taking care not to damage the shaft or housing ring.
• Clean surfaces in order to make them impeccably smooth. To do this, use a very fine abrasive tape. Remove residues of fat with a degreaser (brake cleaner).
• Position the new gaskets flat on the ring.
