Sourcing Onan CCK engines

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   When I look for an Onan 20HP on Marketplace I come up with all manner of results. The few actual Onan 20HP always seem to be different than the engine on my AC 720. I'm sure there must have been other tractors and machines equipped with this engine but I have no idea what to look for. I know there are plenty of tractors out there being sold for a song and I'd like to get a few with the Onan CCK so I can start hoarding spare parts.

Sort of related, bought a starter motor off E-bay. I wasn't expecting greatness. It was all I could find. The $60 starter is the same thing as the $100 one so far as I can tell. Being an idiot I went for the more expensive one thinking it might be somewhat not crap. If you're stuck for a starter motor I probably wouldn't go for the expensive one. Fit is not great and neither is performance.

	I'd probably like to have that pump, depends what you want for it. I'm on shoestrings but I can give a fair price for it I hope. Also can you check this thread out? Looking for the air filter lid and whatever holds it on. Mine is long gone. I think it was a V band clamp that held it but not sure. https://www.allischalmers.com/forum/looking-for-onan-air-filter-lid-and-retainer_topic207129.html
