Rear axle seals

[Lynn Eades]

Maurice, unless you're going to park on steep sidings, I don't think your ever going to have a problem with them mixing. The level in the diff is lower than the axle tubes, and your probably packing your wheel bearings with high melting point grease that isn't going anywhere away from the bearings. The seals in reasonable condition will be enough of a physical barrier, which ever way you fit them. I myself, would however fit them to keep the oil out of the bearings.
You've probably already decided that anyhow.

Hi Maurice and Lynn

The picture of the seal looks like those used on 3-ton Chevy CMPs as well and I have never found a modern replacement. So if anyone does find a modern equivalent please make a general posting on the source.

Does anyone have the Carrier part number for this seal so we can see if it is the same as used on Ford and Chevy CMPS?

There was a lengthy thread on these type seals (outward sealing) concerning trucks some time back that I will try and find.

These seals on the trucks are really not critical as you really need to get the truck on quite a side angle for the differential lube to run out this far in the housing, but on a carrier it maybe much more critical.

Cheers Phil

Yes phil , the seals on chev, 15cwt 4x4 upwards , and Ford , and Carriers use the same seal.

Are these seals steel encapsulated?
Do they have a steel outer rim then a rubber lip?
Is there a spring inside the rubber lip as for a rotary shaft seal?
I know a company over here that may be able to either make them or source them.
Can I have full dimentions and rubber hardness please and will enquire, they are only local to me!

Maurice,

As discussed earlier, I don't recognise the seal as I don't think my truck has it.

Can someone point out the part number, please? See attached exploded view.

Thanks,
Hanno

Maurice & Hanno,

I have emailed some scans from the British Chilwell Catalogue and manual for the UC to you both that show these parts very well. I could not post as the scans are 3Mb.

Cheers,

Hanno your truck should have them . The seal we are talking about is the seal on the picture from Lynn. it is a metal washer with a leather lip ., there is no spring in it to expand it just a washer with a leather surround .
Marc in your exploded view, I cant see which way it is pointing , Chev manual is not clear , Ford not , and carrier is also not pointing it out , because they are drawings.

Maurice,

If I look at the seal it is an U-shape and cylindrical on the outside. It falls over the outside of the steel plate with the U groove. Because it is cylindrical on the outside diameter it shouldn't matter which way you install it? It is only to hold the grease in so not very critical if it doesn't seal a 100%. It is called: Retainer, grease, shaft (split ring). I have a couple NOS in my workshop but will not be there till Saturday. If you want I can have a look at them and get back to you.

Cheers,

Thanks Marc,

I've grabbed some of the pictures in your scans, see attachments.

The "Retainer, grease, shaft (split ring)" you mention is no.54 in the first drawing.

Hanno and Marc these are the British seals . T he ones used on Canadian CMP`s and canadian carriers have a lip which faces to one side or the other
