Default Is this the right washer set for shimming mbx6 / 6T diffs

Are these the washers for shimming outside of the bearings (against the diff housing) and the pinion?

any 13x16 shim will do. i wouldn't pay that for shims. here's you a link with shims and different thickness so you can dial it in just rite.

i had a 6t a while back but i think the pinion used 8x16 bearings. if so, you can use a 8x10 shim. i never had to shim the pinion on my 6t though. hope this helps.

Thanks again robbieg

I have pretty bad front to back movement on the pinions so figure they need shimming, or is this normal? if its normal how much slop should there be. The front diff pinion moves about 1.5 - 2mm and the rear under 1mm.

Or should i be shimming the diff tighter so the ring gear pushes harder against the pinion?

the pinion gear is installed through the 2 8X16 bearings that are installed in the diff case. then the center shaft is installed onto the pinion gear and the
set screw is tightened (with loctite on the threads). there should be little to no for/aft movment of the pinion gear at this point. you would then shim the diff gear so as to have no side to side play, and some gear back lash.
the manual is availible at mugen seiki for download.

HTH, Dave

when you install the axle and grub screw on the pinion this should be done with the diff case split. you can push the pinion towards the outside of the diff housing while holding the axle as far on the pinion as posible then tighten down the grub screw. this method should take care of any in/out movement. if not then shim it.
