Mb jeep tranfer case oil seal

Jo..
Use a Speedi Sleve and leave the old seal alone..
the quickest and sensible way
to repair worn shafts
To seal efficiently, radial shaft seals must run against a
smooth round surface - the seal counterface. If the
counterface becomes worn, and it usually does, then the
seal will no longer be able to fulfil its function, which is
to retain lubricant and to exclude contaminants - solid
particles as well as liquid.
Normally, the counterface will become grooved as a
contaminant particle is caught under the seal lip and
abrades a track as the shaft rotates. As this continues, the
seal will allow more particles to pass or get stuck, and
seal efficiency deteriorates, eventually leading to malfunction
of the component the seal is meant to protect.
To rectify the situation it is necessary to repair the
SPEEDI-SLEEVE® GOLD with a surface
hardness between 80 and 85 HRC for
heavy-duty applications.
counterface on the shaft - a simple seal replacement will
not be sufficient.
To repair the shaft it is usually necessary to dismantle
the machine in order to be able to handle the shaft and
then to grind down the counterface until it is smooth
again. If the grooves are deep the original size of seal
will no longer fit properly - a seal with a smaller bore
diameter has to be found.
Now there is an easy way to repair the counterface
with the shaft still in position and without having to look
for a different size of seal. The answer is the SPEEDISLEEVE

However, using a speedysleeve still requires you to put a new oil seal in or you will end up with the same problem, besides you cant use a sleeve in that area anyway as your yoke for the drive shaft slides over it with a castle nut on the end.

Its a selector shaft seal.

Hi Jason - Alex - Lynn

Thanks guys for the input, very interesting following your comments and I apologise for using incorrect terminology, ie: "Counter Shaft'. I can see one must be more acturate when seeking advice. As a novice in these things, my confidence is growing with the good advice. Thanks guys.

Cheers

Tony

Hey Tony With your picture in your first post, was it 19 or 30 that oil is leaking from? Because if its parked and oil is leaking from 19 with out running, you may want to drain about 6 liters of oil out of it...your oil level shouldent be that high, if it is then you have bigger problems as oil is migrating from the t-84 wich it shouldent.
