PLANETARY GEARTRAIN/OUTPUT SHAFT (Continued)
(17) Check planetary geartrain end play with
feeler gauge (Fig. 212). Insert gauge between rear
annulus gear and shoulder on intermediate shaft as
shown. End play should be 0.15 to 1.22 mm (0.006 to
0.048 in.).
(18) If end play is incorrect, install thinner/thicker
planetary snap-ring as needed.
REAR CLUTCH
DESCRIPTION
The rear clutch assembly (Fig. 213) is composed of
the rear clutch retainer, pressure plate, clutch plates,
driving discs, piston, Belleville spring, and snap-
rings. The Belleville spring acts as a lever to multi-
ply the force applied on to it by the apply piston. The
increased apply force on the rear clutch pack, in com-
parison to the front clutch pack, is needed to hold
against the greater torque load imposed onto the rear
pack. The rear clutch is directly behind the front
clutch and is considered a driving component.
