NOTE: If gears are being replaced, use the exist-
ing shims. The numbers are scribed onto the
gears: the ring gear has the number on the oppo-
site side of the gears, and the pinion gear has the
number on the end of the pinion gear shaft by the
splines. If no number is present, it should be con-
sidered as being in the 0 category.
NOTE: If the gear case housing is being replaced,
proceed to the following Shimming Proce-
dure/Shim Selection sub-section.
