What model D4?
Still trying to figure that out. Rear serial plate covered by winch, engine plate is missing. I've cleaned the block where the engine plate was, but can only see a couple partial numbers. Going to etch the area to try and raise the rest of them. Even if it works, I'm not sure the engine was never changed.
I ordered an operators manual for the 6U and 7U models, seems accurate for mine, 24v direct electric start, not a conversion.
6U/7U is close enough. Takes #3H2033 glow plugs. Check ebay or Cat for that part number.
Our channel highlights machines from the earliest Holt and Best track-type tractors, equipment from the start of Caterpillar in 1925, up to units built in the mid-1960s.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
