Onan 132-0123 Water Pump Bushing
The Onan 132-0123 Water Pump Bushing carries and guides the part that runs inside it, giving a plain bearing surface with the right clearance and material pairing. Because it is pressed in rather than machined into the parent part, it can be renewed many times over the pump life.
Measure the bore or check for play rather than judging by eye. Any detectable rock in the component the bushing supports, obvious ovality, or deep scoring means fit a new one. Check the mating surface at the same time, because a scored shaft chews new bushings quickly. This part is listed for Onan water pumps 132-0115 and 132-0251 on MDJF 15 kW generator sets.

Frequently Asked Questions
Q: What causes them to wear quickly?
Grit and shell carried in raw water, plus running with a worn shaft or with the pump out of alignment.
Q: Should the mating part be replaced too?
Check it. A scored or undersize shaft will wear a new bushing out quickly, so fixing only one half of the pair is false economy.
Q: How is it removed?
Usually pressed or drawn out. Support the housing properly so the bore is not distorted during removal.
Q: Do I need to lubricate it on assembly?
Assemble with clean oil on the running surface so the first start is not made dry.
