Oil in Planetary?

[nastcat]

I have a Frankenstien skidder and am trying to figure out what type of oil to use in the planetary hub..It has axles out of a Hough, but i think they are Rockwell axles.  What kind of lube do i use in the planetary hub?   ???

80-90 gear oil maybe?

Do I use the same in the differencial and how much is it going to take?

[oldseabee]

Same oil, the diff and planetaries are connected through the axle housing so the oil transfers back and forth from each.

I use 140 gear oil.You better buy a 5 gal pail if its empty.

Thanks everybody, I don't know if the differental is empty but the planetary didn't have more than a 1/4 cup in it. Thinking I better check all the fluid levels.  I probably should drain the diff and other planetary and put all the same oil in all of the axle.
