Provides two separate views of the upper gear housing driven gear
being properly shimmed using the Sierra installation tools.
FIG. #1
FIGURES #3 - #4
Provides the same views of the drive gear being shimmed
in the same application.
NOTE:
This installation cannot be performed
correctly without the Sierra 18-9856 shim tool.
Improper installation will result in gear failure.
The .025 referenced in FIG #2 &
FIG #4 is achieved when .026 will not fit the
