Colt Case Ingersoll Garden Tractors

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.

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 got popcorn, watching!

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!

Complete unit , Emerald Plus 4000 . Bore and stroke equivalent to 18 hp engine . Using it for a short block to replace the bad 16 hp it came with .

Lets just say that there is No ridge at the top, No where on the bearings and the rods or the cam lobes .

Dave

Turning the genny taper down to 1" straight . Milling for 1/4" key

As you can see it has extensive ware . Based on what everything looks like . I don't think it has even finished brake in .
Spent the day cleaning and reassembling the short block . Have a rebuild gasket kit from OnanParts.com

Yep, wore out, you better box up the whole thing and send it my way for proper recycling

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 .
