Jet Pump Wear Ring 144mm ID for Yamaha VXR 650 1991-1995

Jet Pump Wear Ring for Yamaha

The Jet Pump Wear Ring for Yamaha is a 144mm ID replacement ring that restores the close clearance between the impeller and pump housing for consistent thrust and reduced cavitation.

Overview

This Jet Pump Wear Ring for Yamaha is a direct replacement for a worn or scored pump housing ring, sized at 144mm ID to match the impeller diameter. It keeps the impeller tip clearance tight so the pump moves water efficiently instead of losing pressure. Ideal for riders rebuilding a pump or chasing a loss of top speed on a VXR 650.

Good To Know

Q: When should I replace the wear ring? A: Replace it when clearance between the impeller and ring grows enough to cause cavitation or a drop in top speed. Inspect the ring any time the pump is apart.

Q: Does it include the pump housing? A: No, this is the wear ring only. Reuse the pump housing and impeller unless they are also damaged.

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