Onan 132-0112 Water Pump Gasket
The Onan 132-0112 Water Pump Gasket seals the joint it is fitted to on the pump, keeping raw water inside the wet end and out of the bearing housing and the engine bay. It also sets the running clearance across that joint, which is why a gasket of the correct thickness matters as much as the seal itself on a flexible impeller pump.
Gaskets fail by hardening, splitting at the fastener holes, and by being torn during disassembly. The usual symptoms are a salt trail or a slow drip at the joint, air drawn in on the suction side so the pump will not prime, or corrosion creeping across the flange. Always fit a fresh gasket when the joint is opened, and clean both faces back to bare metal first. 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: Can I reuse the old gasket if it looks intact?
It is not worth it. The gasket has already taken its compression set, and refitting it usually produces a slow weep at the joint.
Q: Do I need sealant as well?
Normally no. These gaskets are designed to seal dry on clean faces. Sealant can squeeze into the pump and cause more trouble than it solves.
Q: How should I prepare the faces?
Scrape off all the old material, avoid gouging the metal, then wipe both faces with solvent so they are dry and oil free.
Q: What torque should the fasteners be pulled to?
Follow the figures in your Onan service literature and tighten in a cross pattern, working up to the final torque in stages.
