Sealing my transmission output
« on: March 30, 2010, 05:41:01 AM »
Hi guys!

My transmission output is leaking.
1990 k5.

I searched the forum and found people talking about a seal and an o-ring on the shaft.
In the drawings i can only find the o-ring.
part 92055:

I must admit that i didn?t take off the sprocket yet.  :roll:
My question is now if the o-ring is the only thing that i will probably have to replace and if it is easy to change, without getting the shaft out of the case or something...

thx

It is easy to replace. I have found lots of times that it does not need to be replace it only gets pushed out of the way by high pressure water washing. If you pull the sprocket and then pull the spacer from behind the sprocket you will find the o-ring on the shaft.

The seal that you will need to replace is directly behind the sprocket. (and can be replaced from the outside) Behind this is your spacer, then the o-ring that will need replaced.

If your seals and o-ring are clapped out and need to be replaced you also need to replace the metal coller or flip it over if it has never been done before. It gets groves in it and it can leak again even if you put a new seal in.

The knuckle dragging pikey who owned mine before me decided it didnt need the spacer..... :x
And lo, I did loft the front wheel and carried it forth to the unbelievers, and cast it down before them and said unto them ''look now upon the might of my throttle control ye pitiful cretinous ones''
And the unbelievers did quake in their boots....

I now replaced the seal, the o-ring and the coller.
I pushed the seal that far into the case that it alignes with it.
Guess that?s right?!

 Yes that's correct.
The oil seal seats flush with the case.     (Clymer M447-2 pg.181)

  O-ring goes on the output shaft 1st then the sleeve/spacer  then sprocket & Clip  (Service Manual 9-2 Final Drive)
