DRIVELINE/AXLE 4-11
• 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.
Driven bevel gear side
NOTE:
The shims (driven bevel gear side) are available as a set
(24945-26810).
TOOTH CONTACT
After bringing the backlash within specification by changing the
secondary driven bevel gear shims, it will be necessary to check
tooth contact.
• Remove the secondary gear case. ("4-4)
• Clean and degrease the secondary drive bevel gear teeth,
and apply a coating of machinist’s layout dye or paste to sev-
eral teeth.
• Reinstall the secondary gear case, with removed shims.
• Rotate the secondary driven bevel gear coupling several turns
in both directions.
• Remove the secondary gear case from the crankcase, and
observe the tooth contact pattern made in the dye or paste.
• Compare the tooth contact pattern to the examples as shown
in 1, 2 and 3.
Backlash Shim adjustment
Under 0.03 mm (0.001 in) Increase shim thickness
0.03 – 0.15 mm
(0.001 – 0.006 in)
Correct
Over 0.15 mm (0.006 in) Decrease shim thickness
