Specs At A Glance

Good To Know

Q: How do I know when the wear ring needs replacing? A: A drop in top speed, increased cavitation on acceleration, or visible grooves and dents in the ring are signs it is due. Measuring the inner diameter against the 155.5 mm spec confirms wear.

Q: Does the impeller need to come out to install this ring? A: Yes, the jet pump must be removed and the impeller taken off to seat a new wear ring in the housing. Inspecting the impeller and bearings during the same service saves a second teardown.

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