That is how they were made. My guess to act as a drain for water & leaking oil seals......[/QUO
thank you !
armmen , can you tell me how much of the tranny fluid do I have to drain to replace the pinion shaft seals . I know I have to pull the final drive housing and I don't know how high the fluid is .That is how they were made. My guess to act as a drain for water & leaking oil seals......
yeah , after I put the new seals in, with out the final drive pan cover on, I tighten the track and moved forward about 3 feet then backed up 3 feet ,when I looked at that side I just worked on, I noticed a small amount of tranny fluid dripping off of the bull gear from up above so I assume its the seal that separates the tranny to the final drive which is the pinion shaft . I think ? lolJust drain it all.
If the oil isn't very old, carefully drain it into clean containers & reuse it.
Explain why you are pulling the final drive housing?
I thought it was only the axle seal that was leaking??....
if I didn't notice it it would be leaking into the final drive . never had any tranny fluid in the final drive though when I first drained it to work on . about a quarter cup came out in all . I now have it pulled apart again . I cant put it back together with that happing . I don't know if I caused it by that little bit of movement with out gear oil but maybe I did .yeah , after I put the new seals in, with out the final drive pan cover on, I tighten the track and moved forward about 3 feet then backed up 3 feet ,when I looked at that side I just worked on, I noticed a small amount of tranny fluid dripping off of the bull gear from up above so I assume its the seal that separates the tranny to the final drive which is the pinion shaft .

what do you think ?armmen , can you tell me how much of the tranny fluid do I have to drain to replace the pinion shaft seals . I know I have to pull the final drive housing and I don't know how high the fluid is .
....... about what?.....??what do you think ?
I wanted to know what you thought about the tranny fluid dripping down from above the bull gear . it must be a pinion shaft seal right ? and do you think its coincidence or did I cause harm by moving the dozer that little bit with no oil in the final drive ? . thanks for the heads up on shims ........ about what?.....??
I've already answered this question - drain all the transmission oil.
What did the old oil in the final drive look like? It should be heavy gear oil, was it thin looking? as if the transmission oil may have thinned it down??
If you do decide to pull the final drive, be careful of the spacer shims located between the final drive & the transmission housing.
They are very expensive, so don't be tempted to drive a wedge in between them to separate the two.
Clean the shims & the mating surfaces really well & reuse them.
Prime with brake cleaner, allow to dry & use some Loctite 515 to seal the flange.
