Good To Know

Q: Is this an original Yamaha part? A: This is an aftermarket replacement crankshaft oil seal designed to match OEM specifications and cross-reference 6S5-81167-10-00. It is not an original Yamaha product.

Q: Can I reuse the old seal during a rebuild? A: Seals are wear items and should always be replaced once removed, since the lip loses its sealing edge. Installing a fresh crankshaft oil seal is the safer choice during any rebuild.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
