Well boys and girls I think I am about to just throw in the towel and get myself a Buick wagon !!

My stock R1 LSD was torn up so I got myself a KAAZ LSD with a set of 4.33 gears. Put it all together and now the pinion is sitting too low in the crown wheel, I painted the CW in yellow and the Pin in red and rolled them to see how they mated together. I tried adjusting the crush washer on the pinion and as best as I can to get the spacing but that's it. only other thing that can be done to adjust the backlash and spacing of the teeth are the two spacers or shims on either side of the LSD itself and it's bearings. ..sure enough unlucky me.. I need shims now.

Presently, one shim is 246 thousands and the other one is 276 thousands.. the replacement shims must total the same width but they each must be of different thickness such that the LSD will move off center causing the crown wheel to move back away from the pinion teeth to get the backlash required and the spacing of the teeth of both.

NOW, Where the heck do you get shims other than the stock ones ??

..and NO, you can't grind off one side to move it because the bearings will not be properly loaded.

Please Advise,

I did this also and I used the stock shims, I dont know what other shims you can use other than stocks ones there is a list of them in the shop manual. I ordered one of all they had in the country and went form there the only thing bad about that is that I have all the others left over

Thanks for the reply.

From the FSM, there are 19 shims in total and I called Ocean Mazda... as usual, they don't stock them. I'm going to try to caliper the distances and work out the calcs then correlate with the FSM to see which range i should try first..

Do you wanna' get rid of those shims you have ? Depending on which ones you have left over, they may or may not work for me. I can PM you or reply here when I have an idea of which range I'd need and you can check if you have them or used them when you did yours.. seems like each one is numbered ..so it shouldnt' be too difficult to identify.

Thanks again for the reply.
