Good To Know

Q: What does a bearing housing do on a Yamaha GP-R 800? A: It holds the drive shaft bearing in place so the shaft stays aligned between the engine and jet pump. A worn housing can cause vibration, noise, and faster bearing failure.

Q: Should I replace the bearing at the same time? A: It is often wise to inspect the drive shaft bearing while the housing is out, since reusing a worn bearing can damage a new housing. Confirm your model year before ordering.

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