• Measure the backlash as follows.
• Set-up a dial gauge as shown in photo.
 09900-20606: Dial gauge (1/100 mm, 10 mm)
09900-20701: Magnetic stand
• Adjust the dial gauge so that it touches the secondary drive
bevel gear cam dog; hold the driven bevel gear securely, and
turn the drive bevel gear in each direction, reading the total
backlash on the dial gauge.
 Secondary bevel gear backlash
Standard: 0.05 – 0.32 mm (0.002 – 0.013 in)
NOTE:
When measuring backlash, hold the left crankcase horizontally
pull the secondary drive gear to take the bearing play out.
• If the backlash is not within specification, the shims (Driven
bevel gear side) must be changed and the backlash should be
re-checked until correct.
Refer to the chart for appropriate changes.
NOTE:
When changing the shims (Driven bevel gear side), measure the
thickness of old shims. Using the thickness of the old shims as a
guide, adjust the backlash by referring to the chart.
