Good To Know

Q: Does this rotor come as a complete pump assembly? A: No, this listing is for the rotor component itself, so the surrounding pump parts are not included. Reuse or replace the other pump pieces as your service manual directs.

Q: Should the rotor be replaced on its own? A: It is commonly replaced during a pump rebuild and is often paired with related wear parts. Check the pump housing and driven parts for wear before reassembly.

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