ADJUSTMENT
Set a dial gauge on the driven bevel gear as
shown.
Measure the backlash by turning the rear
propeller 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 for
appropriate shim thickness.
Bevel gear backlash
Standard: 0.03 - 0.15 mm (0.001 – 0.006 in)
＊
Adjust the backlash by referring to the
chart at the right and using the thickness
of the removed shims ad a guide.
