onan genny engine rework
Onan genny motor tear down started I was told that the engine was low hours and the meter agreed with that , but you just never know . PO. said it was pulled due to control board failure. He said they hardly used it for years as they camped at plug in parks , but when they started going to different places they needed it to work . So they replaced it and I got it for $200 about $150 a couple of years ago . Now you tell me does it look like low hours .

Note I have not done any cleaning on the motor other than blowing the crud off the out side before disassembly. Dave

Re: onan genny engine rework
looks pretty good Dave.
Did you buy just the motor or the complete unit?
What HP is it?

Oh wow Dave! That's a new engine! Std piston and you can still see the criss cross on the cylinder wall! Score!

I wanna see you dial bore gauge it, and what the mic says on the crankshaft! Now this is what I call high quality programming!

Re: onan genny engine rework
Got the heads on and resealed the intake this morning . Useing heads , fly wheel, intake , exh. , tins , ignition from original engine . The original engine did not have oil filter , but the genny did so I have to cut a hole in the tin and find the extra air gasket I have Somewhere tucked away in the shop .
Stater, flywheel ,starter and valve covers this afternoon . Tomorrow clean fit and paint tins Carb. and ignition .
