Hi, I have an ONAN P220that was made for Sears. The Sears serial number was a silver decal that is now illegible.

 

Is there a good way to find the Spec number?

 

sure would help ordering parts. 

 

Thanks a million, Ken McCubbn

Can you post the tractor model & serial numbers?  I'd bet one of us can find out.

Thanks Red. I don't have the Sears tracor that it came in. It was installed in a Case 446 that I bought. I was hoping to be able to find some Onan identifier on the engine. Thanks much. Like site, have used some manuals members have posted. Just don't talk (or know) muh.

I have a P220 so I'll see if it still has a serial number.  Most parts don't require a serial number though.  I get any new parts usually through Onanparts.com.  Most all the parts are just identified by the P220 engine model.  The serial denotes special things mostly, like length of crankshaft or diameter of crankshaft on pto end, special oil pans, etc.

Sorry, the numbers aren't legible on mine either.  Appears the fuel line has been rubbing it.

Best place to get parts from is Cummins. They are pretty cheap also.

You can download both service and parts manuals here, while numbers are nice not many changes were made to the P220 as far as I know to affect parts from one to the other. I think the parts manual would be your best bet to find out what you have, also pictures taken from all sides could help someone on what you have too.The is a Yahoo group for Onan's which may help.

Thanks. I got the parts manual and service manuals from here. Many thanks to posters. Spec # becomes issue when you don't have all the original parts. Thanks for the Yahoo tip. Site is great. Thanks to all.
