Remove the circuit board cover (34) and gasket (33). If present, disconnect the transducer (25a) from J1 on the circuit board (25c). If present, disconnect the IS circuit field wire from J2 and J3 on the circuit board. If present, remove the circuit board (25c) and TDC sensor (25b). Unscrew the strain relief (35) from the gear housing and pull it and the transducer conduit out of the housing. Do not disconnect the transducer from the outlet port (P). Unscrew the locknuts (15) from the tie rods (3). Unscrew the tie rods (3) from the gear housing. Unscrew the slider cylinder (2) from the gear reducer. 1. Apply antiseize lubricant to bore of coupling. NOTE: When installing an IEC 112M/B5 or 100L/B5 Frame electric motor, ensure that the motor adapter (59) and screws (60) are in place before mounting the motor on the gear reducer. NOTICE When installing the electric motor, always ensure that the motor shaft key cannot move out of position. If the key works loose it could cause excessive heat and equipment damage. Align the key on the motor shaft with the mating slot of the motor coupler, and the four mounting holes with the holes in the gear reducer (1). While one person supports the motor (19), install the screws (37*). Torque to 75-80 ft-lb (102-108 N·m). Reassembly NOTE: Kit 15H886 includes a motor coupler (28), already installed in the gear reducer. The coupler fits all NEMA 182/184 TC Frame electric motors. NOTE: To install an IEC 112M/B5 or 100L/B5 Frame electric motor, order a Motor Adapter Kit. 15H880 15J893 Description Coupler Kit for NEMA 182/184 TC Frame 3 or 5 HP motors. Mounts IEC 112M/B5 or 100L/B5 Frame 3 or 5 HP motors to gear reducer. [. . . ] Remove the plug from the TDC sensor port at the back of the circuit board cavity. Apply pipe sealant and screw the TDC sensor (25b) into the port. Torque to 66-78 in-lb (7. 4-8. 8 N·m). Install the strain relief (35) and the transducer conduit into the gear housing. e. [. . . ]
