WD45 part out. questions/history

I found this tractor close by and thought maybe I could save it. The engine sat to long with water in it, One rear rim is really rusted and bearings in the right final where shot. So the best solution is parts. Many questions about what this tractor did and repairs that were made. The tractor was never repainted, very few new parts and not much rust. It has cultivator brackets, worn spots on the frame from a loader and extra holes in the frame. The pistons and liners had been replaced with oversized. The crankshaft had new standard bearings. The clutch was new with a 9 spring pressure plate. The PTO still had the factory shear bolt. The hand clutch is completely new. The shifter lever has lots of movement side to side. Third and forth gear had wear. I suspect power shifting. Only one spring was missing from the tractor. All the others were still on the tractor and in very good condition. Including quadrant and brakes. The draw bar had no welds, bends, or brakes, but was missing the snap coupler release lever and chain. The hook in the bell had very little wear. The lift latches wear never off. Has an after market seat. I think a joy rider. The lights were not rusted, broken, or bent. Hydraulic hoses and lift cylinders were fitted with quick couplers.  I think a well cared for but a little rough use tractor. 

Antifreeze was to the top of the radiator, the radiator had been repaired. The head gasket was fine and was an aftermarket gasket. Water started coming out when I took the manifold off. The fellow I bought it from left it outside. He bought from someone else for $800 and it was running then.

Could have been parked because of the R/H Final Drive Bearing issue.

Final Drive Brgs. are common between WD and WD-45.

Get a Final Drive from a WD donor, then start on the engine.

Thank you. Does it set back further than the stock seat?

4" bore with a dish in them sounds like the factory power crater pistons for a WD45.   Overbores are traditionally a 4 1/8".

I thought all these 226 gas engines in the WD45 were dished pistons. Thus the name power crater engine.

Thanks Alex. So did they come both ways? And what was the application for each?

Thanks so much Doc. I just looked there and saw all the pics. One picture is worth 1000 words. Sure clarifies that. 

Oh yeah! I fully realize that Mike. LOL. I don't even know for sure what is in mine because it had a rebuild at local machine ship. But from the factory they would have been one design or one design and maybe an update?

Never know what you will find when the tractor is no longer used or a new owner picks up an Alice chambers with fenders and two point cheap.

I have boroscope as well. Should peak in mine one day and see.
