Onan 132-0132 Water Pump Retaining Ring
The Onan 132-0132 Water Pump Retaining Ring locates a component axially inside the pump so it cannot move along the shaft or out of its bore. It is a small part with a large job, because the bearing and seal positions inside the pump depend entirely on it staying seated in its groove.
Retaining rings lose tension when they are overspread during removal, and they corrode in a salt water environment. A ring that no longer springs tight in its groove can jump out under vibration, letting the part it retains move and destroying the pump internals in short order. This part is listed for Onan water pump 132-0110 on MCCK 4.0 and 6.5 kW and MDJF 15 kW generator sets.

Frequently Asked Questions
Q: Does the ring have a right way round?
Many do. The stamped or chamfered face goes toward the load. Note the orientation of the old ring as it comes out.
Q: What happens if it is not fully seated?
It can pop out under load. The part it retains then moves, and the internal clearances that keep the pump working are lost.
Q: How do I check the groove?
Clean the salt out and look for rounding, widening or corrosion pitting. A damaged groove will not hold a new ring securely.
Q: Should I keep spares aboard?
They are small and inexpensive, and they are easy to lose or distort during a job, so most owners carry one or two.
