How To ... REMOVE AND REPLACE DRIVE MOTOR ( Continued )

Step 7

Remove the two DRIVE MOTOR ASSEMBLY mounting SCREWS securing the ASSEMBLY to the MOTOR MOUNTING BRACKET by using a 1/4” hex wrench. Remove the DRIVE MOTOR ASSEMBLY from the unit. Pivoting the MOTOR MOUNTING BRACKET may be required to remove the ASSEMBLY.

Step 8

Align the new DRIVE MOTOR ASSEMBLY with the MOTOR MOUNTING BRACKET. Locate the new DRIVE MOTOR ASSEMBLY into position and secure IN PLACE with the two SCREWS. (Support the DRIVE MOTOR ASSEMBLY with one hand beneath it while inserting the SCREWS with the other hand). Install the DRIVE MOTOR BELT onto the DRIVE MOTOR PULLEY. Be sure the DRIVE BELT properly engages all ribs on both the DRIVE MOTOR and the FRONT ROLLER PULLEYS.

Step 9

Check that the SHAFT KEY located on the DRIVE MOTOR SHAFT is properly seated within one of the four KEY slots in the PLASTIC FAN and that the PLASTIC FAN rests against the shoulder in the MOTOR SHAFT. Reposition the SHAFT KEY and FAN as required if they are not properly aligned.

Step 10

Use a STRAIGHT-EDGE to align the flat sides of the DRIVE MOTOR PULLEY and the FRONT ROLLER PULLEY. The faces of the two PULLEYS should be in- line (coplanar). If the PULLEYS are not aligned, loosen the two SET SCREWS on the DRIVE MOTOR PULLEY and adjust as necessary. Once aligned, recheck the SHAFT KEY and PLASTIC FAN positions per Step 9 above and tighten the two DRIVE MOTOR PULLEY SET SCREWS.

Step 11 Install the 1/4-20 nylon-insert LOCK NUT onto the

TENSIONING BOLT and, if available, use a belt tensioning gauge to tension the DRIVE MOTOR BELT to 100 lb (+/- 5 lb).

Step 12

NOTE: IF A GAUGE IS NOT AVAILABLE, RE-INSTALL THE LOCK NUT BY TURNING IT THE SAME

NUMBER OF TIMES IT WAS TURNED ON REMOVAL. BE SURE THE TENSIONING BOLT IS POSITIONED PROPERLY IN THE SLOT AT THE FRONT OF THE MOTOR HOUSING DURING TENSIONING.

Connect the three DRIVE MOTOR lead wires to the proper DRIVE MOTOR TERMINALS (See Step 4). Attach the new SENSOR CABLE to the black retaining clip. Connect the SENSOR CABLE CONNECTOR to the CONTROL BOARD terminal. Install a new WIRE TIE to secure the SENSOR CABLE and the three DRIVE MOTOR LEAD WIRES in the same location from which the previous WIRE TIE was removed.

Step 13

Manually rotate the DRIVE MOTOR SHAFT. Check that all wiring is adequately dressed to clear rotating components. Redress wiring if required.

Step 14

Reverse Steps 1 through 3 to return all parts to their proper positions.
