Ser1 replaciong transfer box oil seal?

Hi

I want to replace the oil seal on the rear output shaft of the transfer box
on my 86" series 1.
Looking at it there apperars to be a number of shims between the speedometer
housing and the transfer box itself. The manual says for the end float on
the shaft.

What I want to know is if I bugger about with this bit and take it off the
transfer box to remove the old seal when I replace it will it leak oil
through the shims. I can't see how five shims, no gasket and just tight
bolts can make a good seal.
Has anyone got any words of advice about this job, is there a way to ensure
oil doesn't leak through the shims, call me cynical but I just know it will!

Cheers

Tony

Well if it didn't leak before, leave the housing on, you don't have to
remove it to get the seal out. If you haven't got a hook on a slide hammer
then you can lever it out with a strong screwdriver if you are careful not
to damage the edge where the seal goes back in.
If you want to remove the housing to take out the odd shim to reduce the
backlash in the bearings just make sure you wipe the shims and the case
clean before you replace them, I've never known any to leak afterwards and
I've done plenty.
Use a piece of tube of a slightly smaller diameter than the new seal to
press or knock it in so that it goes in squarely without damage.
