I bought a 1953 D7 3T years back with a stuck engine that I was hoping to repair and use. I was able to get the pony motor to fire and run but couldn't free up the main engine. I finally got around to removing the heads from the main engine and I found 1 cylinder stuck but worse I found lots of water had gotten in through the valve covers. The water from the valve covers rusted the rockers, valves and looks like cam too. It has a few bent push rods also. The pistons have moved some in the bores from when it was originally stuck. It leads me to believe that the previous owner tried to pull it when the motor was stuck and moved the engine some until its seriously stuck or broke/damaged other internals. I provide this information to say that I am giving up hopes on repairing it and am checking to see if anyone is interested in the entire machine or parts from it before I move to scrap it. I'm happy to take pictures of other components if people are interested. I have attached a few pictures for now. Machine is located in central Arizona. I don't have any means to move or load it.

So after posting I had some people send me messages saying the dozer looked completely salvageable. So this weekend I put an 8 foot cheater bar on the crank bolt and was able to pop the stuck piston with liner out. After getting it out the motor turned freely. I’m now back in the mode of trying to get it fixed and back together. Sorry to those folks that needed parts after my post. If I’m still not able to get it fixed I will let folks know if parts are available again. Right now though, fingers crossed that I can get the thing running.
