transfer case seals

[iain reed]

hi all
on the way back from paxinia i blew the transfer case oil seals (bugger)
THE QUESTION IS... can i replace them without removing the transfer case ?
if so any tips.. any help would be good.. thanks in advance

Yes. Quite easy except that the rear seal involves removing the handbrake, which makes it more complicated.

While it can be done from solely underneath, it may be easier to remove the driver's floor panel and the centre panel on the seat box.

A workshop manual will help, particularly if you are not mechanically experienced.

They are the same seals used on all the series gearboxes. Just be sure that you check the condition of the seal surface on the flange. It may need replacement or a "speedi sleeve" or similar.

Having replaced the front output seal and installing a speedi sleeve on my '49 a few months ago, I did the same to the rear on Sunday. I backed the vehicle onto ramps to elevate the rear of the gearbox, to both provide room to work underneath, and keep the oil in the gearbox when the drive flange was removed. I removed the hand brake drum, but not the shoes or mechanism. The seal was easily removed with a seal remover, and the new one installed. Once completed, I dicided that I wanted to de-oil the shoes and backing plate. I then removed the shoes, which is easy if the drive flange is still removed. I then burnt the oil out of them while they were supported in a vise, and cleaned the backing plate with brake cleaner. After a test drive, no oil was seen to be leaking from the hand brake. More importantly, the hand brake now abruptly stops the vehicle, and stalls the engine.

I carried out all of this work without removing any body or floor panels, working entirely beneath the vehicle while it was supported on heavy ramps.
