The bearing has to be first set without the seal fitted, the hub nut and axle marked and then reset to the marks after installing the seal. But I agree that an undersize seal is likely to get nipped somewhere along the line.
Alex.
Just out of interest how much torque did you have to apply to the hub nut to get it to the marks....ftlb or equivalent?

It’s felt.

Surely 30 seconds with a scalpel will fix it?
Both thickness and I/Diameter......have you actually tried it?.

Dennis you are splitting hairs worrying about a 70lb axial loading (pre or otherwise) on those bearings. That assuming the felt didn't crush over time in any event.
The side load capability on corners will be measured in tons !
Hooligan, my gentle elderly cornering does not do that :)

The real point of the matter is that the "own the manufacturing rights..........including drawings" firm ought to recognise there is a difference and be able to supply the correct item to save all this fafing about. I will put the right one in and not be the experiment to see if wrong one can be fitted and how long it thus lasts.

It does beg the question - did the “correct” seal start out, or end up, at 8mm? I don’t think comparing an old, compressed seal and a new one for thickness is like for like?

I recall someone spending days trying to find a replacement square section seal of a particular size only to find he should have been looking for a standard o ring - the old one having compressed over time into a square profile of a different cross section.

Dennis,

Just a quick look question - if you are being told there is only one seal (part number 6376) and this appears to be reflected in the parts books, what is the part number supposed to be of your thinner seal? There is an assumption that your car had the correct parts fitted before...

I must agree with Dennis, there ARE Two different sized seals AND the steel backing plate.
QH kits all seem to contain the narrow version.
The early uprights have a smaller profile shoulder and to use them up Reliant introduced the top hat type collar to push the bearings furthar away, thus giving a bigger clearance for the disc to the trunnion bolt.
Will get my records/books out later and see what the change over time was, and part numbers.

I used a standard industrial lip seal and turned up a spacer to suit the hub. Never had much faith in the standard felt setup.

Dennis I suppose you're referring to my schoolboy error with the axle pinion nut??? In this case the torque was so small as not to be measurable.
