NOTE

The procedures outlined in step 54 (fig. 5-

138) are necessary to space the trans-

mission properly in relation to the trans-

mission driving disk (on engine or input

drive transfer gear). If correct spacing is

not established, the driving disk will be

subject to strains which will cause its

failure and possible transmission damage.

Figure 5-137 shows the correct spacing,

stack control spacers, and spacer retainers.

Step 54 (fig. 5-138) outlines the methods

for establishing the required spacing.

Attach a hoist to lifting eye 4910-673-3801

(10865773) (A) and apply sufficient lifting force

(50 to 100 lb) to eliminate all end play. Position

straight-edge (B) on converter pump cover (C), as

shown.

Using a micrometer depth gage (D),

measure and record dimension (E). Subtract height

of straight-edge (dimension F) from dimension (E),

and record the difference. Subtract this difference

from 1.566 inches. Select spacers which will equal

(within

0.010) inch the resulting dimension.

This is the proper spacer thickness to be used at the

drive stud.
