Hey Pete,

I believe you are referring to the small o-ring under the pinion cover, the size is 6x2.� The part number for this is:� 089-409-637A

When I last purchased one, I had to go to the dealer and the cost was $2.

Subject: Bus work in the barn and Tiny O Ring on Differential

Hey Volks:� Check out my pics of some trans/diff work up in the barn today :
http://picasaweb.google.com/pnoceanwesty/JoesVanTrannyWork#

Wondering what the little O ring is called located on the differential -
under the cover plate that goes around the pinion. The Bentley makes no
mention of it in the 2.1 Automatic section on 29.50 and 39.51.

When ordering parts, I asked a lot of questions and thought I had all the
seals/gaskets in the kits and individual orders but this little guy is not
around. Kind of stopped us in our tracks as I don't want to use a 21 year
old O ring over again. Do I have to get that at the dealer?

Either way, was a fun bus day in the barn. More work to come.

Anyway
Pete
