Reverse Gear Bearing Adaptor Assembly
INSTALLATION
NOTE: If the reverse gear, reverse gear adaptor, large thrust bearing, or bearing race in
the gear housing were not replaced, install the same shim(s) (or the same thickness of
shim(s)) that were taken out when adaptor was removed. If the reverse gear, reverse gear
adaptor, large thrust bearing, bearing race, or gear housing were replaced, install 0.008
in. (0.51 mm) of shims.
NOTE: If backlash has already been checked and it has determined that it needs to be
adjusted, (see Checking Reverse Gear Backlash), adding 0.001 in. (0.025 mm) shims will
reduce
the gear backlash by approximately 0.001 in. (0.025 mm). Subtracting 0.001 in.
(0.025 mm) shims will increase
backlash by approximately the same amount.
Example 1 (if backlash is too high)
