Jeep Wrangler TJ. Manual — part 497
(26) Install the #7 needle bearing to the rear sun
gear (Fig. 112). The number 7 needle bearing has
three antireversal tabs and is common with the
number 5 and number 2 position. The orienta-
tion should allow the bearing to seat flat
against the rear sun gear. A small amount of
petrolatum can be used to hold the bearing to
the rear sun gear.
(27) Install rear sun gear and #7 needle bearing
(Fig. 113).
(28) Install front carrier/rear annulus assembly
and #6 needle bearing (Fig. 114).
(29) Install front sun gear assembly and #4 thrust
washer (Fig. 115).

(30) Determine proper #4 thrust plate thick-
ness.
(a) Select the thinnest #4 thrust plate thickness.
(b) Install #4 thrust plate (Fig. 116) using petro-
latum to hold into position.
(c) Install input clutch assembly. Ensure the
input clutch assembly is completely seated by view-
ing position through input speed sensor hole. If
the speed sensor tone wheel is not centered
in the opening, the input clutch assembly is
not seated properly.
(d) Remove the oil pump o-ring (Fig. 117) and
install oil pump and gasket to transmission.
Tighten the oil pump bolts to 30 N·m (265 in. lbs.).
Use screw-in dowels or phillips-head screw-
drivers to align pump to case. Be sure to rein-
stall O-ring on oil pump after selecting the
proper No. 4 thrust plate.
(e) Measure the input shaft end play with the
transmission in the vertical position. This will
ensure that the measurement will be accurate.
(f) Set up and measure endplay using End Play
Set 8266 and Dial Indicator Set C3339 as shown in
(Fig. 118).
(g) Measure input shaft end play. Input shaft
end play must be 0.127 to 0.635 mm (0.005 to
0.025 inch). For example, if end play reading is
0.055 inch, select No. 4 Thrust Plate which is 0.071
to 0.074 thick. This should provide an input shaft
end play reading of 0.020 inch, which is within
specifications.
(h) Remove oil pump, gasket, and input clutch
assembly to gain access to and install proper #4
thrust plate.

(31) Install input clutch assembly with proper
thrust plate (Fig. 119).
(32) Install #1 caged needle bearing (Fig. 120).
(33) Replace cooler by-pass valve if transmission
failure has occurred (Fig. 121).
CAUTION: By-pass valve MUST be replaced if trans-
mission failure occurs.
NOTE: To align oil pump, gasket, and case during
installation, use threaded dowels or phillips screw-
drivers.
(34) Install oil pump gasket (Fig. 122).
