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.

DO NOT USE A STANDARD THREE JAW PULLER.

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.

[nyquil junkie 318]

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.

All very good ideas.

This is my hub puller. Works well. Cheep to make. Plenty of variations have been nade.

 

 

 

 

[nyquil junkie 318]

Well.. after backing out the set screw the hubs fell off... more or less.

 

The hubs are beat up and wallowed out from the hub flopping around, which I didnt notice for apparently years. The keyway beat the hub and the axle slots up pretty bad as the hub got more loose. So the hubs are toast, and the axle keyway slot is a little larger than it should be. Maybe someday I'll trip over a set of old hubs not quite so beat and maybe.... yeah maybe. Until then, its getting sat on some blocks and parts I need elsewhere are getting used.

 

Too bad. This one did more work and more miles than WH probably designed it to do. Maybe someday, It'll get repaired and put back to work.

Lincoln at A to Z Tractor in PA has clamp on hubs. 

Or... a complete transmission transplant.  

[nyquil junkie 318]

I found a couple hubs in my junk boxes... didn't know I had them. I put in new keys, and the hubs are now pretty snug. Good enough. I removed the outer tires on the back, and put some oil in the case.... it'll leak out eventually but, who cares. I'll add some now and then. Its good enough to tote the little wagon around, take feed to the cows or go inspect/fix the fences. When I i get some time I'll find the seals and put a set in.  Its better than getting set under a tree to rot. I need a bigger machine w duals to crawl up into the high rough fence lines, which is what I'm going to slap together from this 520HC roller I drug home the other day.  

[ineedanother 2,618]

Duals are hard on axles and bearings unless the terrain is smooth. The outer wheels just have too much leverage on the axles. Sometimes it's just better to go with aggressive over-sized tires and chains.
