You might want to look up member Onanparts and PM him he has answers for all of your Onan questions. I know that you have to be very careful with pistons and rings for them! There is a thread on here from him that explains it all!
I would really caution you jumping into one of these that doesn't run. You can get into a good amount of money real quick. They are good engines but Onan is proud of their parts. Especially if the wife isn't on board. Been there done that - not fun.
I have not heard of anyone with personal experience with this e-bayer but he appears to have a good feedback record. I checked the sales he has made of these engines and 3 or 4 have purchased the re-built Onan's over the last year or so. All of them appeared to have a good experience with the rebuilt engine. I also noticed the price on the rebuilds has gone up about $200 over the past year! :fing20:
Hey guys, thanks for the help/info! I went and looked at this 1983 318 I was sorta interested in. It's not in as good a shape as I would like, the engine looks to be shot, and or course, the wife said "No!"
The gentleman I spoke with seemed to have a lot of JD knowledge and 4 or 5 JD tractors. He spoke of having a lot of parts and Onan engines around the homestead. This kinda scared me off - if he was so good with the Onan engines and rebuilds and such, why would he not rebuild/repower the 318 and get much more for it?
Anyway, here's the link to his ad on CL and some pictures I took because... everybody likes pictures!
