I don't want to remove the turbulence (combustion) chambers from the engine, but may have to, as well as the head. What can I do about the head? Is it possible to have the head welded by an engine shop, and have little or no compression leaks from that area? Is this dozer rare? I have the idea that there were about 367 made, which sounds a little odd. The head is also cracked somewhere, I was told in the exhaust valve seat. What else can I do to help the engine become free? Heating and cooling, with a torch? I would imagine that would cause stress on parts. I have filled the upper bores of the engine (intake side) with diesel fuel and penetrating oil, and poured some diesel fuel down the exhaust manifold. The dozer must have sat outside for some time, at least before I started working for him (knew him since I was smaller than the height of the tracks!) I would guess moisture managed to get into the bores while sitting one of the cylinders was probably exposed by having the exhaust vavle pushed in or intake valve. It is tired needing an engine rebuild from low compression, steering clutches, and reverser clutches (this is equiped with a reverser.) I guess it is mine now, or at least till it is running. He used it in the early 80's while building his home, as well as his mother's. The fellow who I help and work for here in Western NY happened to have an old 1962 John Deere 1010 Dozer with a 4 cylinder diesel engine in it. With the hobby of old iron, I decided I needed another "vehicle" besides my 1963 Cub Cadet. I collect old hit and miss engines, and other odds and ends. Hello, I am 14 years old an currently, well, and engine nut.
