94J series are an initial model D5 not D5B. 94J2338 should be a 1974 build, direct drive transmission, 3306pc engine @105h.p.
Thanks, I'm not that familiar wit Cat. The dozer I am looking at has been taken apart. The seller didn't really know other than on the seat box there was a decal "D5B". The ID plate has been painted over a few times and hard to read. I could make out the 94J2238, and figured that number is the serial number. I see I made a mistake in the number, it is 2238 not 2338. I could make out the 3308, so that matches for the engine.
He had problems with the right final drive. Pinion and bull gear are worn, destroyed some of the bearings, and wobbled out the spacer tube between the final drive hub and the sprocket. He had a friend in a different state who had a final drive and sold it and shipped it to him. Turned out it was a 44 tooth sprocket instead of a 49 tooth sprocket. He didn't know this until Cat came out to install it and let him know. He said Cat came out a few times and he's done putting more money into it. He does have new bearings and a pinion gear. Hours are unknown.
I also noticed the track adjuster spring is broke on the left side and what chrome is sticking out of the adjuster cylinder is rusted off on both left and right sides. It doesn't look like the adjusters work. He said the engine was rebuilt not long ago and the hydraulics were strong and didn't leak. I did see about 3/16" of liner on the steering brake of the right side, since it has been removed. He wants 5k for it, but looking at everything else, hard to say how it moves and runs without taking his word for it. Seems like an honest guy, but it's been sitting for at least 2 years maybe more.
I think we can do the work, but it looks like a lot of time, more money on adjusters, bull gear, spacer, and not sure what else we could run into.
