*C2 *C2 PAR 83-86 TORQUE CONVERTER REBUILD CHAP 5, SEC IV (2) Remove 12 stator roller bearings and springs from the stator (fig. 147). (3) Remove the roller thrust bearing assembly from the freewheel race. Remove 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. CLEANING 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. ASSEMBLY a. Torque Converter Cover (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 Pump (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 correct 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 ball 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. 107
