onan NHC oil pump

Recommended Posts

I'm looking for an oil pump for an Onan NHC engine. Does anybody out there have one in good condition they would be willing to part with?

Thanks!

Ken,

Having rebuilt many CCK's and some NHC's back in the "day", I wonder if they used the same oil pump assy (but maybe just different pickup tube/screens one could swap)? You could look into this since the CCK's/parts out there are somewhat plentifull. I remember the NHC was an "OK" engine, but this was the first aluminum block L-head twin series Onan put out and thus their durability started on the decline (IMHO). They did not hold up as well as the cast iron CCK series.

Revision:

Looking at the current ePay picture for Onan oil pump (lots of them out there), it sure looks to me like the pumps are the same accross the L-head twin board with just different pickup tube configurations. There's even a few NHC complete ones at this time.

Yup, I saw those. I just wonder if I'll wind up with the same issue I have now?

The rod bearings are showing signs of being starved for oil.:( Actually I had a machine shop build the bottom end of this motor for me. He did nothing with the oil pump except "inspect" it and add the gaskets for the correct internal clearance.

I've been running Chevron Delo 14W40 oil. I have one of those pad heaters on the crankcase so the oil is hot for the winter starts. Total of MAYBE 6 hours on a rebuild.

I knew I should have just bit the bullet and re-powered my skid steer:(!

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
