27. Shims (84) may be required between the return spring retainer (44) and the return spring
retaining ring (43). To determine if necessary, and how many, proceed as follows:
a). Place four clutch return outer springs (46) into the four high range clutch piston (49) pockets
with tapped holes in center. Place the return spring retainer (44) over the piston with its four
holes centered above the four springs.
b). Compress the springs and install the spring retaining ring (43).
c). Screw into four topped holes, four bolts (3/8”-16UNCx6” with a minimum of 32 [mm] thread)
(A, Fig. 7E.25), 90 [
°
] apart until they bottom. Torque the bolts to 13.6 [Nm]. This will cause
the piston to make contact with the clutch pack.
d). Determine the average distance (A, Fig. 7E.25A) between the high range clutch piston (49)
and the return spring retainer (44). To obtain this figure, use a depth gauge
(B, Fig. 7E.25A) to measure the distance C from the clutch piston to the outer edge of the
spring retainer in two places.

Then remove the return spring retainer (44) and measure the retainer thickness D with
a micrometer in two places.

Subtract the retainer thickness D from the total distance. C – D = A
