Onan 132-0113 Water Pump Cover Screw
The Onan 132-0113 Water Pump Cover Screw clamps its joint on the pump to the designed load. It sounds like an ordinary fastener, but the wrong length in a pump housing either bottoms out before the joint is tight or projects into the wet end where the impeller runs.
Replace any screw that is pitted, has a damaged head, or that did not come out cleanly. Clean the threads in the housing, apply a marine antiseize if your Onan service literature allows it, and tighten evenly in a cross pattern so the joint pulls down flat. 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: Should I use antiseize?
A marine grade antiseize on the threads makes the next service far easier, provided your Onan service literature does not call for a thread locking compound instead.
Q: How many are fitted per pump?
It varies by position and by pump. Count what comes out and match it before you order.
Q: What is the right tightening pattern?
Cross pattern, in stages, so the cover or flange pulls down evenly and the gasket compresses the same all round.
Q: What if one shears off in the housing?
Stop before it gets worse. Penetrating fluid, heat and a proper extractor, or take the pump to a machine shop rather than drilling it freehand.
