Secondary Gear Shim Inspection and
Adjustment
Backlash
Refer to "Secondary Driven Gear Assembly Removal
and Installation (Page 3A-3)".
1) Tighten the secondary driven gear case bolts (1) to
the specified torque.
NOTE
Do not install the O-ring on the driven gear
housing at this stage. O-ring is installed after
backlash and tooth contact are correct.
Tightening torque

2) Measure the backlash as follows:
• Install the backlash measuring tool on the driven
bevel gear coupling, and set-up a dial gauge as
shown in the figure.
Special tool
(A): 09924–34510 (Backlash measuring
tool (φ27 – 50)))
(B): 09900–20607 (Dial gauge (1/100 mm,
10 mm))
(C): 09900–20701 (Magnetic stand)
• Adjust the dial gauge so that it touches the
backlash measuring tool arm at the mark; hold the
secondary drive bevel gear securely, and turn the
secondary driven bevel gear coupling slightly in
each direction, reading the total backlash on the
dial gauge.
Secondary bevel gear backlash
Standard: 0.03 – 0.15 mm (0.001 – 0.006 in)
(A)
• If the backlash is not within specification, the
shims (driven bevel gear side) must be changed
and the backlash should be rechecked until
correct. Refer to the chart for appropriate
changes.
NOTE
When changing the shims (driven bevel gear
side), measure the thickness of the old
shims. Using the thickness of the old shims
as a guide, adjust the backlash by referring
to the chart.
