BACKLASH
After assembling the final gear case ("4-24), measure the
final bevel gear backlash as follows.
• Install the backlash measuring tool on the drive bevel gear
coupling, and set-up a dial gauge as shown in photo.
# 09924-34510: Backlash measuring tool (27 – 50 mm)
09900-20607: Dial gauge (1/100 mm, 10 mm)
09900-20701: Magnetic stand
• Adjust the dial gauge so that it touches the backlash measur-
ing tool arm at the mark; hold the final driven bevel gear
securely, and turn the final drive bevel gear coupling slightly in
each direction, reading the total backlash on the dial gauge.
% Final bevel gear backlash
Standard: 0.08 – 0.16 mm (0.003 – 0.006 in)
If the backlash is not within the specification, adjust the shim
thickness as follows:
• Remove shims from final gear bearing case and final gear
case, and measure total thickness.
• In order not to change the clearance between final driven
bevel gear and bearing, the total thickness of the shims
installed after a change is made must equal the original total
thickness of shims.
• If backlash is too large:
a) Install a thinner shim pack 1 between final driven bevel
gear and final gear case.
b) Increase thickness of shims 2 between final driven bevel
gear bearing and bearing case by an amount equal to
decrease above.
• If backlash is too small:
a) Install a thicker shim pack 1 between final driven bevel
gear and final gear case.
b) Decrease thickness of shims 2 between final driven gear
bearing and bearing case by an amount equal to increase
above.
