THIS WORK PACKAGE COVERS:

Determining Nominal Shims for Transmission Main Bearing Support

DETERMINING NOMINAL SHIMS FOR TRANSMISSION MAIN BEARING SUPPORT

1. If original shim pack thickness is not known, or if certain new parts have replaced original parts, nominal shim

thickness must be calculated as outlined below:

2. Replacement of any of the following components may affect shim pack dimension required:

Transmission main bearing support

Output bevel gear set

NOTE

MD1 (Mounting Distance) is etched on output bevel drive gear and must be recorded before gear

is installed in this group.

3. Assemble low and reverse range planetary carrier assemblies as outlined on WP 0074 00.

4. Measure and record dimension indicated by X shown below. Note that micrometer depth gauge must be

subtracted from the height of the parallel bar to find dimension X.

X

5. Record dimension indicated by MD1 on Figure 1 of WP 0020 00. This dimension was etched on output bevel

drive gear and was recorded during rebuild of low and reverse range planetary carrier assemblies (WP 0074 00).

NOTE

Record dimension from housing being used; each housing is stamped with its specific

dimensions.

6. Record dimension, which is indicated by D on Figure 1 of WP 0020 00. This dimension is stamped on a web at

left side of transmission housing.
