Forgot to mention tractor also has a winch .I cant find out how to fill or check final oil. Please help .
The transmission and bevel gear share the same oil but not the finals.Cat went for a time saying to us a lite oil but has gone back to saying gear oil.I have always used gear oil.

The transmission and final drive use the same oil 80/90 gear oil and you have a plug each final drive for refill
Regrading the winch, you didn't state if it was a D4 or D4N. In either case, there are drain plugs at the lowest point on the cases on both sides. A ways above the plug on the left side, there is an oil level plug and towards the top there is a fill plug. According to the instructions, 90 wt oil is to be used. I use 80w-90 in all compartments; tranny, finals and winch.
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."
