Good To Know

Q: Do I need special tools to install this? A: Pressing a jet pump bearing in and out usually calls for a bearing press or driver set. Have seals and O-rings on hand since pump removal exposes them.

Q: How do I know the bearing needs replacing? A: Grinding noise, rough shaft spin, or play in the pump shaft are common signs. Inspect the bearing any time the pump is apart.

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