(2) Remove 12 stator roller bearing s

and springs from the stator (fig. 147).

(3) Remove the roller thrust bearin g

assembly from the freewheel race. Remov e

roller thrust washer from the stator (fig. 147).

If either bearing or thrust washer is damaged,

replace both parts.

(4) Remove the front and rear retaining

rings, two large thrust washers and two small

thrust washers from the stator assembly .

Mark the stator cam and stator assembly for

reference in reassembly. Press out the cam.

84. CLEANIN G

Refer to par. 71 for cleaning recommen-

dations .

85. INSPECTION AND REPAIR

Refer to par. 72 for general inspection

and repair recommendations. Repair and re-

build points of measurement for fits, clear-

ances and wear limits are indicated by small,

lower case letters in fig. 373, fold-out 2. Re-

fer to par. 236 for wear limits information.

86. ASSEMBL Y

a . Torque Converter Cove r

(fig. 373, fold-out 2)

(1) Install double-row ball bearing 143,

retaining ring groove outward, on the hub of

torque converter cover 69. Press the bearing

until it is firmly seated on the hub.

(2) Using spanner wrench 8351495 (fig.

36), install converter lock nut 144 (fig. 373,

fold-out 2). Torque the nut to 75 pound-feet.

Deform the lip of the nut into the two grooves

in the hub of converter cover 69.

(3) Install bearing support sleeve 104.

Install the retaining ring on the bearing.

(4) Install the input drive transfer gear

and, using a 5/8-inch wrench, secure it with

twenty-four 7/16-20 x 1 self-locking bolts (fig.

142). Tighten the bolts to 64-77 pound-feet

torque.

b . Torque Converter Pum p

(fig. 373, fold-out 2)

(1) If screw 85 and bolt 86 or weights 84

were removed from the converter pump, in-

stall new replacements.

Note . Be sure to install correc t

weights at the locations previously

identified.

(2) Install ball bearing 91 in converter

pump hub 88.

(3) Install retaining ring 92, retaining

bearing 91 in pump hub 88.

(4) Install two hook-type seal rings 87

on converter pump hub 88.

(5) Install converter pump hub 88 with

component parts in converter pump 83 and se-

cure with four lock strips 89 and eight self-

locking bolts 90. Tighten the bolts to 9-11

pound-feet torque. Bend a corner of each lock

strip 89 against the head of each bolt 90.

c . Torque Converter Turbine. If bal l

bearing (fig. 146) was removed, press a new

bearing on the hub of the converter turbine.

Be sure the bearing is firmly seated on the hub.

d . Torque Converter Stator

(1) Install retaining ring 93 (fig. 373,

fold-out 2) into stator assembly 94. This ring

must be installed into the groove at the rear

of the stator (rear identified by the sharp edges

of stator vanes).

(2) Install rear washer 95, pushing it

through the stator until it seats on the retaining

ring. Install thrust washer 96, seating it on

the inward surface of washer 95.

(3) Press stator cam 99 into the stator,

positioning it to match the marks made at dis-

assembly .

Note . Cam 99 must be installed in the

same position it had prior to removal.

The stator assembly must freewheel

in the direction of converter rotation.
