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
rechecked until correct. Refer to the chart (a)
at the page 10-41 for appropriate shim
thickness.
Bevel gear backlash
Standard: 0.03 - 0.15 mm (0.001 0.006 in)
If the backlash is too small (under
0.03 mm, 0.001 in), replace the driven
bevel gear side spacer with a thinner
shim.
If the backlash is too great (over 0.15
mm, 0.006 in), replace the driven
bevel gear side spacer with a thicker
shim.
