7. Determine nominal shim pack thickness by substituting dimensions recorded in Steps 4 through 6, above, for X,

MD1 and D in the following formula: (MD1 + X) – D = nominal shim pack thickness. Select proper combination of

shims to equal this shim pack thickness.

NOTE

Do not install steer bevel drive gear at this time. When correct output bevel gear backlash and

gear tooth patterns are obtained, carrier group will be removed to install steer bevel drive gear

and its shims.

8. Install shims and low and reverse range planetary carrier assemblies group as outlined in WP 0074 00.
