clearance of the bevel gear is out of specification
or if parts are changed (output shaft, bevel gear
shaft or housing).
There are 2 adjustments to perform on the bevel
gear.

The bevel gear backlash is adjusted by finding the
proper shim thickness E as per following illustra-

The bevel gear axial clearance is adjusted by find-
ing the proper shim thickness J as per following
illustration.
