Onan 132-0089 Water Pump Shaft and Bearing Assembly
The Onan 132-0089 Water Pump Shaft and Bearing Assembly supplies the pump shaft complete with its bearings already fitted and set, so the rotating group goes back into the pump as one unit. That removes the press work and the risk of damaging a bearing during assembly, and it guarantees the bearing spacing is right.
This assembly is what you need once salt water has been through the bearing housing. Rumbling or rough bearings, a shaft grooved at the seal track, or end float you can feel at the impeller hub all point to replacing the whole rotating group rather than trying to save the shaft. This part is listed for Onan water pump 132-0110 on MCCK 4.0 and 6.5 kW and MDJF 15 kW generator sets. This is the flat shaft build, not the keyed shaft version.

Frequently Asked Questions
Q: What else should I replace at the same time?
The shaft seal and the slinger at minimum, plus the cover gasket, since the pump has to come apart anyway.
Q: How do I know the bearings have failed?
Turn the pump by hand off the belt. Roughness, notchiness or a rumble, or any felt play at the impeller hub, means replace the group.
Q: Can I just replace the bearings on my old shaft?
Only if the shaft is unmarked at the seal track. In practice the shaft is usually pitted by the time the bearings go.
Q: Is the drive end the same on all versions of this pump?
Not necessarily. Flat and keyed shaft builds exist, so compare the drive end with your old part before ordering.
