Hey Bro give me a call when you got a second I got something really big to talk to you about. 510 938 1861

I used shims on the outside of the bearings (shims that did not come with the kit that I had 13x16). The front took .1mm on the ring gear side and the rear took .1mm on the diff cup side. I did notice that the front shimming changed once I got it all bolted up in the car, it got tighter, so I backed it down to .1mm

Havent got to it yet, been busy with fam stuff lately. I would say shim the pinion like the manual says and then shim the ring gear so it just has a high spot that may bind a little. I'll let you know in a couple days when i get there.

hi,

thanks gigi

Zeb I use the tko special clutch bearings (blue seal face eachother to the I side of the cb). And shimmed with a tick or little bit more of play on the cb. Is it possible that your cb is too tight. It should have a little movement or end play. That's very fast to blow clutch bearings.

Frank L - I have read many of your posts and respect your comments. I have a question that locally I have been getting a wide variety of answers to, none of which I am very satisfied with. My XB9 seems to need a very steady diet of clutch bearings. I have had them installed new and get one tank practice, then two 6 min Qualifiers and totally seize and spit ball bearings in the ten minute main. Shouldn't one set of clutch bearings make it through this amount of use? Sure replace next week but seriously I have to change them before the main every time. Something must be wrong because I read other guys have no issues with them.
Running 13/47 so center diff plate installed and Aluminum top.
