There is a guy not too far from here that put together a 2255 puller. He has the steel plate wheels no hydraulics etc and he got it down to 8500. It has a turbo and he has it set for about 300 engine horsepower. I turned one up once along with a few of the 3150 engines. I forget which one it is but I needed a continunity tester to check it. Going to mow lawn this morning, want me to think about it? I had a 3208 shop manual away, but I think I have a friend who is in the Cat business that has one yet.
