I'm parting out a mid 70's john deere 450c crawler loader. The transmission is bad, the sprockets and chains have been removed. 4 cylinder diesel motor (Runs great) Loader with cylinders Rops Canopy (Has the backhoe attachment flip up roof) Both final drives w/ bull gears Sprocket counter weights Fr...

I have a 450c loader/backhoe and my manual suggests SAE 30 in the motor and AW 68 in the Trans, finals, and hydraulic system. Are all
AW 68 the same?????

What kind of prices have you guys been quoted for the new chains, pads, and sprockets for 450c size dozer?

I would grind the crack out and fill it full of weld (nickel) by a good
qualified welder that has welded up cast before. If the crack is not
already open or too long, it should hold just fine.

I think you could probably weld that up with nickel rods.

I have a 1974 John Deere 450c that needs a new transmission housing. Mine has been cracked and I need to replace it. Does anyone know where
I can get a used one for a reasonable price? I have located a couple, but
they are some what expensive. Some help would be greatly appreciated.
