cat D2 questions

While 10 psi isn't very high, I believe it is within the normal limits for the old CAT engines with very large bearing area relative to the horsepower/rpm they see.

Lots of D2's with steering clutch problems..........good thing is you can get the stuff to fix them........probably because there is so much demand even though the last one made is over 50 years old now. Also good that they aren't any bigger tractors, so a cherry picker hoist can handle the track frames and final drives to get into the steering clutches.

Got any pictures of that blade setup. Generally a bad idea to do much lifting off the front of these tractors with no frame support along the sides. There used to be a guy named George Rankin out in California making sheetmetal for those tractors if you cannot find some good used ones.

This is a picture of tractor it looks like a factory built blade from some company

Well its definitely not designed for rooting out stumps! What is the cylinder anchored to on the front of the tractor? Looks like they designed it so the cylinder could "push" the blade up instead of pulling it up.

Maybe someone will recognize the blade.

The cylinder is designed to push the blade up it actually works quite well. The dozer has its own frame structure in front.of the radiator adequate very well its a 10" double box channel iron frame and is very well built
