1855 Massey Onan Engine bearings

breimer · Oct 27, 2010

replaced the entire engine in this 1855 Massey garden tractor. It only lasted half as long as the original. (about 7 years) Now the crankshaft bearing on the flywheel side is totally worn out. I think its because on this tractor there is a pair of belts on the stub adapter that bolts to the flywheel pulling the crankshaft downwards. Just wondering if the original onan engine for a Massey would have had a tougher bearing than the the engine we put in? Any body ever heard of something like that? (engine is a P218G)

I have never seen a p/n for more than one bearing, so I think they are all the same. Maybe belt tension may have some bearing on this. Where they tensioned like the were on the original???

Onan only made standard bearings. Never heard of any heavy duty bearings.
