• Set a dial gauge on the driven bevel gear as shown.
Measure the backlash by turning the driven bevel gear shaft in
each direction, reading the total backlash on the dial gauge. If
the backlash is not within specification, the shim must be
changed and the backlash should be re-checked until correct.
Refer to the chart at the right for appropriate shim thickness.
