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,

Marc,
I believe that "mechanical seal" is the British version, the Canadian one has the leather lip, interchangeable, the plate is also a locking device for the inner hub nut which has a peg / dowel in it. A good seal due to the stepped joint on the U shaped ring.

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

[Hanno Spoelstra]

I would mount them so they keep the grease in.

Where can you buy them?

[Maurice Donckers]

Maybe, Dirk Leegwater. Set up for bearing is first hexagon nut with pin , then lock washer, then that seal , and finally another hexagon plain nut to lock everything .
I always put these seakl back in the*way they came out , but now because they were both different in , it made me think about how they realy should go in , most vehicles I worked on had them the way in to keep the grease in the Bearings.
