Rear axle seals

[Lynn Eades]

Michael, your pictures are to small/ low resolution for me to see.
The inner seals you are referring to, I believe go in the axle tube, the outer being different. The inners are designed to keep the diff oil in the diff and the axle tubes dry. This is a different spec to the axles we have been discussing prior to your post. The earlier axles never used any of those inner 4702's, and the diff oil could inhabit the axle tube. The use of these seals would require a seal track to be finished on the inner end of each half shaft, and a sized area in the housings, which I don't think the early housings are finished for.The 4702 refers to an axle seal the prefix and suffix define the difference between the two. The one available from Macs is the inner one, which yes, is installed with the lip facing in toward the diff, to keep the oil in the diff.

So far we don't have anything on the leather outer seal, other than my photo. it's counterpart being variously; (from Michael's post)
CO1T 4702
O1T 1124
BB 1124 B

The seals you are referring to, I believe go in the axle tube, 1 inner and one outer per side

Which seals are not for the Carrier? Lynn, I cannot enlarge the images to a file size that MLU will accept,
but perhaps if you save them and open in something like MS Paint, you can enlarge them for viewing.

Michael, if you look at the link you put up from Macs, that's the inner.
I now see the inner seal on the first image you posted. It is shown at the top left. There is a printing error as the two (inner and outer)
are identified as the same seal. (not to be confused with the inner hub seal BB 1175 C)

Your outer is marked "Victor 49850"

[Michael R.]

Yes, all good. I see that error issue, and the fact that the count reflects two (2), not four (4). Yes, the outer seal is marked Victor 49850.
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.)
