Hi all,

How bad is the Onan parts availability situation? Can any CCK owners post their parts sources? Are carb. rebuild kits readily available, for example?

Thanks.

Cummins/Onan has around 150,000 active part numbers. Most all parts needed to rebuild/repair the opposed twins, cast iron block CCK/CCKA etc. and the aluminum block "B" series: BG BF BGE B43 B48 & "P" series P216 P218 P220 P224 etc are all available. Gaskets, rings, rods, bearings, pistons, valves etc. Bottom line, Onan stopped manufacturing new engines but never stopped making the most common replacement parts.

It's been almost 25 years since the CCK/CCKA/CCKB series engines were last used on a production line. And.....those replacement parts are still made right here in the good ol U.S. of A.

If Cummins/Onan went offshore and "imported" the parts made with cheap labor they could lower the cost significantly. American made quality is hard to come by these days. The lack of any aftermarket, US or otherwise, keeps the cost up there too.

Also keep in mind that you can still get parts for that 25-40 year old Onan engine. Very few major manufacturers provide that level of spare parts support. Cummins/Onan is probably one of just a few left that do.
