Recently bought a cat D2 serial number 3j1611. I never owned a d2 ordered book for it as it needs steering clutch work or adjustment. Has election start pony motor. Both engines run good oil pressure seems low 10 psi when watm? Undercarriage is roughly 90% but previous owner didn't replace front idler when they done rest and they are junk. Also need the generator for the charging system and both side panels. The blade that is on it isn't like any I've seen before either it has 1 large cylinder mounted vertically in front of the radiator

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.
D2-5J's, D6-9U's, D318 and D333 power units, 12E-99E grader, 922B & 944A wheel loaders, D330C generator set, DW20 water tanker and a bunch of Jersey cows to take care of in my spare time😄

Hi d21smith,
this scan from a Cat service Magazine may explain what ccjersey is referring to with low oil pressures in these old girls.
Cheers,
Eddie B.

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

being a 3J it was never designed to have a blade. it was just to be used as a draw-bar or ag cat that's why your front idler's will be shot, it makes them fount end heavy. if you thinking about fixing your fount idler you can swoop out for lager idler from a U and that will help keep her nose up. nice little 3j
