They are newer engines, late 90's and early 2000's. Seems to be a partnership with Robin.

 

Performer series? OHV, correct?

Onan stopped production of the two cylinder engines in 1998. a company call Linamar made engines and parts for some years after Onan stopped production at Huntsville Alabama plant. After that I don't know.

That brings to mind a question I asked sometime back. I was dreaming and had run across a Case 1816 Skidloader that had been repowered with a Subaru Robin 23 Hp V twin (?) I think. and was wondering how reliable they were.

From my experience and reading on the web, (which is 10% experience, 90% reading) I would put the S/R above a Briggs or Kohler, but below a Kawasaki.

Okay, I finally found it. Robin (Fuji) was contracted by Onan to make the Performer series engines for welders in 2000. In 2003, Linamar quit making engines for Onan, and Onan was done building gas engines. In 2004 Robin quit supplying Onan branded engines for welders, and switched them over to Subaru/Robin stickered units. Still the same engine, though. Parts are available through both suppliers.

Ezgo also used those engines in their golf cars, the TXT models for many years. Parts are available there too if you need anything.

I could swear the onan in my 318, has a Linamar sticker says "made in Guelph ontario"

Had to take another look.

Told their reliable if you keep them clean and serviced.

That would mean you have a replacement motor in there, albeit one that is exactly the same as the engine it replaced. That is, if yours is an 1987 or later model, with a serial number higher than 420000.

 

Linamar started building Onan engines in 1997, I believe.

Hmm interesting, when I got it there was 550hrs on it. Wonder if it blew early or they reset the hour meter.

There is an engine shop I deliver to in Columbus, IN. Every Onan part he has is branded with Cummins. From what I understand all Onans that are now built is produced by Cummins. They are still full force in welders/generators. He was rebuilding one and had a block sitting there. Told me the new ones cannot be bored due to the cylinder walls being aluminum coated in something. I can't remember exactly what it was but it keeps the aluminum from wearing down. They have to be sleeved again with Cummins produced sleeves to retain the coating.

Yes, cummins does own Onan. An my experience with the local cummins dealership was not impressive. I had to tell them how to test a coil last summer. I showed them a page of the service manual and they grumbled a little. Lol
