rear seal

[rob love]

You will likely have to just find a seal with the proper shaft diameter and have a collar lathed up to accept the seal and fit into the bore. However, it seems to me that seal was omitted in later production, and the oil allowed to pass by. I have also seen the seal omitted in the rear of the transmission case. Perhaps the two were allowed to share the oil and find their own levels. It would make the sealing of the transmission to the pinion more important though. I went with RTV between the flanges rather than the wrap around leather gasket in that location.

I was only having a guess as I dont have that book.
I think the MkI* never had a seal between the diff adapter and the gearbox, only the leather gaiter on the outside. Dirk L. has shown an adaper housing that was machined to take a seal. I believe it is from a MkII*

This seal on the pinion coupling is an odd size and I am currently awaiting one being specially made as original. Recently had other seals made for various 70 year old military vehicles, where the sizes were peculiar to that application and no longer available. This is in the UK, I would imagine there are companies in US or Canada doing similar work. Not that expensive either, if I had gone down the road of finding a seal with correct shaft size and machining an adaptor ring, there would not have been much difference.

Richard,
Could you post the info. on the seal when you have it home?The dimensions, material etc.
Thanks,

Doug,

I do not have the new seal as yet, but here are the technical details.

The British army stock number of the seal was LV6-MT1/PT/475227, this denotes it was a Perfect oil seal, with part # 475227, this is stamped on the old seal ( for confirmation).

The Outside diameter is 4.756", Shaft diameter is 2.85" and Width is 5/8".

regards, Richard

Hi Doug,

Here is two views of the newly made pinion seal ... lip material is nitrile rubber.

Richard,
That looks just dandy. Nice work.

What did it cost to get the seal made ??

Hi Dave,

It would have been equivalent to about 55 Canadian Dollars.

Could someone please point me in the right direction for a replacement of P/N C01UC 105759, the rear oil seal for the transmission mainshaft? I have looked at a number of Canadian transmissions, about half of them do not have this seal installed. (Similar to the observation mentioned by Rob L. when discussing the pinion seal C01UC 105387 for Derek E.)

I do not see a transmission main shaft rear oil seal in the June, 1944 edition of the British Chilwell parts catalogue.
However: the May, 1944 Canadian parts catalogue shows the same seal and part number for each of the three Mk. I* variants, as well as the Mk. II* C31 UC Welsh Stowage.
