2. Replacement of any of the following components may effect shim pack thickness:
Transmission housing
Transmission main support bearing support
Transmission main support bearing
Output bevel gear
Steer--drive bevel gear set
Thrust washer
Main bearing retainer
3. Remove low and reverse range planetary carrier assemblies from transmission housing WP 0074 00.

5. Measure and record dimension indicated by A on figure 1 or 2 of WP 0021 00. When this measurement is made,
main bearing retainer is installed without any shims and thrust washer is in its place. Thickness of parallel bar
must be subtracted from micrometer depth gage reading to obtain dimension A.
