Rear axle seals

[Hanno Spoelstra]

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.
