Specs At A Glance

Good To Know

Q: How do I know the crankshaft oil seal needs replacing? A: Look for oil weeping at the crankshaft opening, oil residue on the engine block, or a drop in oil level between outings. A worn seal lip is usually the cause on higher-hour Yamaha 195 FSH Sport 1800 engines.

Q: Should I replace anything else while the seal is out? A: Check the crankshaft surface for scoring or burrs, since a rough journal can tear a new seal lip on installation. Inspect nearby seals and gaskets and replace any that show hardening or leakage.

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