(47) Install snap ring.
(48) Set up dial indicator as shown in (Fig. 137)
and measure 2/4 clutch clearance. Press down on
clutch pack with finger and zero dial indicator.2/4
clutch pack clearance is 0.76-2.64 mm
(0.030-0.104 in.).Set up indicator and record mea-
surement in four (4) places. Take average of read-
ings. If clearance is outside this range, the clutch is
assembled improperly.There is no adjustment for
2/4 clutch clearance.
(49) Install rear sun gear and #7 needle bearing
(Fig. 139).
NOTE: The number seven needle bearing has three
anti-reversal tabs and is common with the number

THICKNESS / INPUT SHAFT END PLAY:
(a) Select the thinnest #4 thrust plate thickness
and install to input clutch assembly (Fig. 142). Use
petrolatum to retain.
(b) Install input clutch assembly into position
and verify that it is completely seated by viewing
through input speed sensor hole. If view through
input speed sensor hole is not as shown in (Fig.
143), the input clutch assembly is not seated prop-
erly.
