Very good engine, parts are hard to find and expensive, when you can find them.

cummins bought onan. parts are really expensive and getting harder to find

 

[Ken Combs]

Parts are not stocked by many local dealers, But that doesn"t mean they are hard to find. onanparts.com is one online dealer, or your local cummins dealer will have or can order them.

Not cheap, but available. And, done right a rebuild 1will likely outlast you, unless you"re a teenager

Sealed Power had kits for em that were a lot cheaper than Onan parts were. They are listed in the industrial engine book, not the small engine. Also check with JD, they used some Onans over the years. Last one I rebuilt JD was the cheapest source for parts. Still ran me about 450 including machine shop work.

Not sure what model you have but some of the clearances are very important like on the oil pump.

external_link has a small engine forum and there is a Onan repairman on there with knowledge on these engines. Has a step by step procedure for overhaul/repair.

I got a complete 18 HP I got with a Wheel Horse as a parts engine. Don't know what if any is wrong with. It's a basket engine, meaning it has been disasembled. I think guy was going to rebuild it. Will let it go cheap.
