Attach the grip/motor, play with the motor height and check it out. You'll notice the bevel gear move side to side relative to the mechbox shell/bushings.

I also do this kind of shimming technique. no shims in the bevel gear. I also sand (remove 1 mm)the upper bushing of the bevel gear to have more space for the bevel gear to move a little bit higher so that the whole pinion gear can get inside and engage to the bevel gear properly.
