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
.001 in. (0.025 mm) shims will increase backlash by
approximately the same amount.
