Rear axle seals

It is close to eight years to the day when this entire topic was kicked down the road by Rob L., Bob, C., Col. Tigwell and Phil W. Everything old is new again.
Just a little more difficult to acquire NOS seals in sardine cans, swimming in oil.

Looking at these seals in your pics guys I may have a solution. Basically thet are not pressure seals, just retainers as mentioned to stop grease and oil swapping over!
The steel plate in the middle has the seal lip bonded to it then??
There is an easy solution if this is the case.
You can retain the plate and just replace the seal edge in soft rubber with a grooved/split seal made to shape and slipped over.

Make sense or have I got it wrong?

I get seals made all the time from a local company and trust me, they have done some complete oddballs for me and one offs!

Hi All

Anytime there is a need to post a large photo in order to get the detail, you can send them to me and I'll post them on my website and we can link back to MLU.

Would strongly suggest though that we post a smaller photo acceptable to MLU so that the photos are archived in the MLU site in the discussion thread.

Cheers Phil

I had another look at the CMP truck parts manuals (will post a picture later), and it is clear to me that the Chevrolet truck axle had an outer axle seal as pictured above. The Ford truck axle had an inner axle seal, just behind the differential bearing - so no need for a seal at the outer bearing.

Proving again that the Ford design was superior over the Chevrolet

(Carriers are a different matter, I'm talking about the trucks here.)

Well Hanno maybe your Ford Manual has a printing error , I have come across several Ford Axles with these seals in . drums on Chev and ford are the same even most chevs have ford stamped brake shoes in . T 16 carriers also have these seals . I got one Ford manual with them in the drawing , and a later parts book without.

Hanno: While I will agree that Ford is superior over Chevrolet in many ways, I might have to disagree on those seals. Having changed the rear inner axle seals on a couple of the fords, I can assure everyone it is not a job to be taken lightly with those split banjo housings. I would far prefer changing the exterior type seal that the chevs (and the carriers) have.

As Micheal posted, we have discussed these very seals a number of times on MLU. The Victor number is no longer any good, however Derk Leegwater does have NOS of these stocked at very reasonable prices. I bought 10 last year just to have on the shelf for future use.

Maurice, You may not be aware that the Ford and Chev brakes of the F8 and C8 are of Chev design, and that all the other (C15, F15, and up) CMP's, use brakes of Ford design.
I guess the Ford / Chev b.s. was happening then, like now, and that some of parts drawings were not given of 100% effort by the biased Chev people
O.K. then if that is not acceptable. then there were lots of errors in early war manuals and parts books, because of the rush to get them out. I think they did a fantastic job.

I took several axles apart, on carriers and CMP`s, but on one the lip faces inward to keep the bearing grease there, on others it faces outward . There is no clear answer in the manuals that I have got .

"5. Install the grease seal with the lip on the seal pointing out, . . ."

Lynn my C15 no11 cab has GM brakes (always poor )they are all round the same as GMC cckw banj front shoes . Brake cilinders are also 1 1/4 front like banjo , but the rear ones are outward the same as 1 1/4 but are internally 1 3/8.
My CGT and C15A have ford products .

[Maurice Donckers]

Michael , thanks , that must be it then , wonder how manny are mounted the other way round , that also makes clear why there are 2 treaded holes in them to pull them out , if the lip is facing inward , then resistancewhen pulling them out would be less.

Hello all.
A product that you can pour into the diff that will lube and stop the seal from leaking Ive only come across this one www.liquidintelligence.com.au has any used these products before? Cheers Lads

[Maurice Donckers]

Shane to my knowledge these products only work on modern rubber seals , not on our old leather seals . it makes the seal to swell a little bit , but in my opinion if a seal is worn , the only way to repair is to replace the seal.
