question Pinion bearing housing oil seals

[Aussie]

I'm attempting to replace the oil seals in the pinion bearing housings that connect the bevel boxes to the transmission shafts but am having trouble with the central metal sleeve. In the pic, the oil seal is the outer (rubber) ring and the sleeve is the central metal bit, which I haven't been able to lever out with a screwdriver. Is there a trick to removing these or do I just need to persist with soaking, heating and levering (destroying the old oil seals in the process, although this doesn't matter since they're being replaced)?

This setup applies to Saladin, Saracen and probably quite a few other MVs.

Thanks, James.

Dumb question! Should have looked at the new seals -they obviously fit over the central metal sleeve so that doesn't need to be removed at all.

Put a couple of screws in to lever the old one out..

No oil inside but the shaft turns ok

New seal will just slide in over the sleeve but I'll give it a bit of a flush with oil first.

Hi James

It would be a good idea to polish the sleeve where the seal runs before you reassemble it.

Thanks John. Good advice and will do.

Also check the bearing. If the seal and sleeve are that grotty chances are the water will have got into the bearing as well; certainly looks like it from the photos.

Thanks Sean

Will check all the bearings but I think most will be OK, apart from a couple (front) that are seized and are soaking in diesel so I can change the bearings ("Ozzie Saladin" restoration).

I just worry when I see things in that state that there's water sitting between the rollers and the races. Often the bearing will feel fine but the slight pitting means when they're used they die very quickly!
