Top pinion seals are leaking oil into the steering clutch case. Have to remove steering clutches and seal and bearing cages for pinions.

First check the final drive breather tube, it exits to a breather in the rear end of the brake cover, these have been known to crack off inside the back end case, SLIGHTLY pressurise the final drive at the breather, remove the brake adjuster cover and see if any air is coming out.
Ok I think I know what you are talking abou. I did notice that when walking the machine fast oil will come out breather tubes. Is this normal? Thanks everyone for the input!
No its not normal, a couple of checks are required before tearing things apart to try and ascertain if its the breather tubes leaking/broken or by-passing the pinion seals, and if those breathers are blocked the final drive oil will be pushed through the pinion seals. We had a whole batch of D6C's in the mid '60's where we had to weld those tubes into the case though the top because they were welded inside the case and it was impossible for a welder to get all the way round from inside.
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.
