Cat TDTO 30 for the trans and 10W for the hydraulics as long as you are in a climate with fairly regualr temps beetween say 0c & 35c.
Thanks Again. I've pulled a lot of wrenches on old stuff, but I have never worked on a modern D-3. Thinking about it, it should be old enough to be in a museum now being that these tractors are pushing 40. The fellows that have it, handed it to me in a bushel basket with the transmission apart. Almost back together now. The service book does not list the oils. As I remember, cat always used that in the operators book which we do not have yet. Dandy Dave!
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."
