Figure 5-57. Figure 5-58. NOTE (4) Place converter pump bearing retainer To make installation of lockup clutch piston assembly easier, put a pencil mark in line with pin nearest orifice in piston (when balance marks are alined as in figure 5-58). Then, when piston assembly is being in- stalled, use pencil mark as a guide to location of pin beneath orifice. One recessed hole in piston is concentric with orifice. Rotate piston slightly, if necessary, during installation to insure that piston engages pins. To make certain that piston is properly seated, measure distance from pump cover mounting surface to piston; this distance should be approximately 1 1 / 2 inches. CAUTION Lockup clutch will not release if piston is not engaged with pins. (5) Install snap ring (9) on converter pump cover (4) hub. b. Converter Stator and Cam Assembly (fig. 5- 53). (1) Position converter stator and cam assembly (fig. 5-59) with largest inside diameter up. Install 10 springs in cam pockets. Ends of springs must be toward center of stator and cam assembly and in deep end of cam pockets. Relative position of spring and roller is shown. (2) Install holder assembly 4910-572-8588 (fig. 5-60) in converter stator and cam assembly. Install 10 rollers in cam pockets. Lubricate rollers and springs with transmission oil. (3) Install freewheel roller race (35), coun- terbored side facing away from stator and cam assembly (16). into stator and cam assembly. Rotate freewheel roller race in a clockwise direction while installing, and seat on holder assembly. (4) Hold freewheel roller race in place, and turn stator and cam assembly over (fig. 5-61). Remove holder assembly 4910-572-8688 by pulling on chain provided. (5) Seat freewheel roller race (35 ) on needle bearing assembly (17). Position stator and cam assembly so freewheel roller race is upward until read y for installation. c. Converter Pump Assembly (fig. 5-53). (1) Position new converter pump hub gasket (26) on mounting face of converter pump (29). (2) Install ball bearing (23) in converter pump hub (24). (3) Install pump hub in converter pump bore, and aline holes. (22) over ball bearing, and aline holes (fig. 5-56). (5) Install eight bolts (20) through four new tab locks (21). Tighten bolts to 9 to 11 pound-feet torque. (6) Bend pointed corners of lock tabs up against flat sides of bolt heads to lock bolts. (7) Replace converter pump flange bolts (30), as necessary, and make sure weights (31) (if any) are in place if pump bolts have been removed. (8) Install hook-type seal ring (25) on pump hub (24). 5-21
