Alright Gentlemen,

I need help. Find attached a photo of my TT rear end axle housing. What you are looking is on the inboard side of the outer roller bearing sleeve.

It is damaged and I want to replace it. What do I use.

damage

Also I bough the following:
-Ton Truck rear axle modern style inner oil set
-Ton Truck axle housing cap set, 6 piece set

Can anyone tell me where does the first one go? Is it on the inboard side of the outer roller bearing sleeve replacing the above damaged part or on the inner side of the ball bearings (inside the pumpkin)
I assume the cap set goes where I removed the caps to get to the roller bearings and sleeve.

I also here's my pumpkin cracked open with the roller bearings instead of ball bearings. Anybody seen this before?

pumpkin

Thanks
Sebatien

So Dave if I understand well, you installed the new type seals on the outboard side of the roller bearings sleeve? When I insert them do i put steel in first against the shoulder or rubber first?

Sebastien, they go on the outboard side of the housing, but inside of the sleeves. In other words, they go into the housing before the sleeves. They seat on the end of the axle tube. It's been a few years since I installed mine, but I don't recall any rubber that would be on the outer part of the seal. They were just basically a standard seal mounted in a washer like "housing" that fit the I.D. of the TT housing. The RTV is what seals them to the housing. You may have a different type. The important thing is to have the lip of the seal facing in so the rearend lube does't leak out. Dave

So I have another question.

When I remove the Axle shaft retainer assembly, there's a lip keeping the assembly together.
To change the felt, do I need to crack the assembly open or can I squeeze the new felt inside?

BTW, I remove bother sleeves like a breeze. Used the tool and turned and they came right off

This 1929 AA Rearend. The Last year they were made. The axles were slightly longer than the "TT" for brake clearance.

I just did mine, I took the old rivet's out and popped the piece out. Repaired it, beat it back into shape and welded it. Then put back in with bolts, turned the heads down to look like rivets again. Then took the other seals apart and put the felt in and put back together. I had to cut the felt allitle smaller and enlarge the hole. I could not make it fit in that space.Also used those new seals, hope it works :-)My rear had ball bearings were yours has roller bearings? Also my new sleeves had not little pin to lock them in position, I welded one on and there was no grease hole, I put that in too. Good luck with yours - that stuff is heavy!

Sebastien,

The seal shown damaged in your first photo is the inner seal for the outer bearing. When I changed mine I just made a bearing sleeve puller out of a piece of 2" galvanized pipe, and nut and a bolt with a head that would fit in the hole in the sleeve. Just catch the hole in the sleeve with the home made puller, depress the dimple, and pull it out. You can then remove the damaged seal and install a new one, then just shove the sleeve back into place. Be sure to pay attention to the position of the sleeve and put it back the way it came out. If you are doing both sides of the truck it's possible to get them in backwards.

Since you have the unit apart I'd go ahead and change the inner bearing seals too. Even though all the TT rear ends I've seen have ball bearings for the inner bearings instead of the roller bearings in yours, the seal situation should be the same. Remember, it's the inner bearing seal that is intended to contain the rear end oil. The outer bearing inner and outer seals (the inner seal shown damaged in your photo) only contain the outer bearing grease.

I hope this helps. After re-reading what I wrote I'm not sure it's clear, but I don't know how else to explain it.
