956XL Rear axle seal

[Badshot]

It's simple enough.
Trumpet off and I think there's a big nut that holds the half shaft in. Everything slides out once it's off.
As you say the steel ring coming out will be self explanatory once you're in.

It's a circlip, a big Un.

Anyone will have Timken bearings (and the seal) for you, number on the side .............
Dont be going mad with main dealer stuff ........

I knew it was something! A few years since I did ours.
I should have remembered as I've still got the big pair of circling pliers I bought to do the job

Off the trumpet? It came off the tractor easy. There's no gasket there, is it just squirty gasket used to seal it?
Just looking to get new bearings and seal now.

Yes, that big ring gear comes off the trumpet housing, it's sealed with loctite 515 or similar.
I wouldn't leave it as it's possible you'll have disturbed ( cracked ) the existing sealer when removing the half shaft.
They can be tight to get off but, mark its position, take it off & clean the mating surfaces, apply sealer & reassemble.

Just getting down to doing ours, break for tea and to ask how the feck you got that circlip out? Ok, I guess I could use screwdrivers but getting the beggar back in?

All advice appreciated

Aye, there was a special tool in the form of a circlip plier that was part of the tool board for those series of tractor's.
You can mess about with long screedscrews but it's not easy, worse to get back on.
They are external circlip pliers with a 90° bend to get under the gear & have the reach to get down to the clip.
Perhaps you could ask your local CaseIH dealer or ex IH dealer to do it for you, take the axle in, or if you know them well enough borrow the pliers.

Didn’t get much chance to have a go but tried at least three pairs of circlip pliers and no go. They are just the wrong shape to get enough release of the clip. When I get more time (patience!) I might be able to get a screwdriver between the shaft and clip and get a hook behind the clip to chase it round.

Failing that I’ll cut and shut some cheapy multifunction circlip pliers to do the job proper.....ish.

Hang on a mo.
Is it the big internal circlip?


I got a set of draper mole grips which had a needle nosed pair in .
I ground the tips in a shape that fitted in but couldn't slip out, worked a treat as they lock meaning you can concentrate on getting the fecker out.

Good man, I was thinking the same too

Grass seed in today though so she’ll have to wait

Doing our 856 this week, looking in picture you don't need a monkey Jack to hold cab when you take cab mounting off trumpet housing? What if I take both sides off at the same time? as I'm not in a huge rush for tractor this time of year so wanted to strip it down then order parts needed. How much more work is there to get into the brakes to check them, I'll be 90% there? Cheers

On the 956 we took the bolts out of the cab mounts and levered the cab up and put some blocks on the top cover to hold the cab up. Brakes are behind the Cover the axle stand is holding up but looks different to the 956. We did both, just blocked under the pickup after we had wedged out the front axle.

I never did a follow up but the trick with the circlip holding the epicyclic on is to stand the trumpet on the hub and lift the weight of the epicyclic with a hoist whilst you pick at the circlip. The circlip stays out of it groove as you work it then.

Guessing you have to drop the back end oil then to get into the brakes and then new seals between back end and trumpet when rebuilding?

Struggling to remember but don’t forget I worked on a 956. The 956 had a seal on the shaft you can see in the above pics between the brakes and the trumpet, those pics don’t so I can only assume on the 856 they run in ep90. No seals on mine, just clean as best you can and load up with squirty gasket. I think we used the blue tube (hylomar?) and no leaks yet.

 

[Gapples]

It's a very long time since I had an 856 back axle to bits
As I remember they have 2 seals in there back to back separating the two different oils.
We once had one that kept emptying an axle oil into the transmission through those seals.

 

[jg123]

Pulled it all apart, bearing had gone and then damaged seal. Looking at diagram there's no circlip holding the outer bearing in place even tho there's a grove as in the pic. Also can't see what holds the thrust washer (2) in place, diagram shows it just on the shaft between the 2 bearings but it would just be free to move up and down the shaft then?!

 

[jg123]

No forget about the washer it won't pass the machining on the shaft. Just double checking there's never circlip stopping the outer bearing moving then

No, I don’t think there is
