beginning with an outside spline plate first and
alternating with inside spline plates until you
have installed 4 of each, as shown in Figure 79.
Note: Lined side must be installed facing up
as shown. Clutch plate amounts may
vary by model.
16. Install the direct clutch backing plate on top of
the last inside spline plate (See Figure 79).
17. Install the "Selective" backing plate snap ring,
as shown in Figure 79, and ensure that the snap
ring is fully seated against the top of the snap
ring groove in housing.
18. Install dial indicator on top of the direct clutch
backing plate, as shown in Figure 80, and zero
the dial indicator.
19. Direct clutch clearance should be:
1.06 mm (.042") to 1.86 mm (.073"). Change
