FIGURES #1 - #2 Provides two separate views of the upper gear housing driven gear being properly shimmed using the Sierra installation tools.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 clearance but .025 will.A service manual should always be consulted for step-by-step instructions.
