855 leaking axle seals

[nyquil junkie 318]

As the title sez... they leak, badly. Assuming the bearings are not shot (knock wood) are these seals just simple oil seals you pry out and tap new ones in, or is there some horrid complication I'm doomed to run into here? Are they just standard off the shelf seals or, some obscure unavailable 1960's part for a 3 speed trans?

Look in the Transmissions section for the Seal P/N interchange list & the tutorial on doing the R&R. SKF seals are readily available.

It is easier if the Unidrive is out of the tractor, but not absolutely necessary.

Getting the hubs off may be an adventure though...

If you decide to remove the trans, get the hubs off first to hold the trans still.

I set that text three times. One for each jaw that you shall not use.  

 

 

An old hub is a good puller.  There are good threads that show good pullers.

And the 3/4"  hitch pin.

Be super careful prying the seal out, one good nick on the axle will have you doing more work.

Leaky seals are a hub removal's best friend  They tend to come off relatively easily as compared to dry ones.

I jacked it up to give it a pre-repair check... both hubs are loose on the axles, or the bearings are shot... or the shafts or hubs are wollered out... I dunno. I'll know more when I pull them off.
