Take backlash readings at several places while
turning the gear shift in each direction and securely
holding the final driven gear. If the backlash is not
within specification, the shim must be changed and
the backlash should be re-checked until the backlash
is within specification. Check to the table for the
appropriate shim thickness.
NOTE
Adjust the backlash by referring to the table
at using the thickness of the removed shims
as a guide.
