SECTION 8. MOTOR DRIVE SYSTEM Warning - Always shut off electrical power to the unit before beginning any service procedures. The motor drive system tear-down procedure covers all components related to the drive system, such as the drive motor, drive belt, motor control, machine control and accelerometer switch. Figure 8-1 DRIVE BELT DRIVE MOTOR The drive belt has six (6) ribs which mate with the face of the motor pulley. The belt encircles the motor pulley and the drive pulley of the spinner. REMOVAL The drive motor is hinged into the left bottom area of the outer tub and secured to the outer tub by the bolt on the belt adjustment wheel. A slot in the mounting bracket of the outer tub allows the motor to pivot and allows adjustment of the drive belt tension. 1. Disconnect power to the unit. REMOVAL 2 . Roll the belt off the drive pulley and remove from the motor pulley. ADJUSTMENT Check belt tension. If loose, remove the belt, loosen the belt adjustment wheel bolt and rotate the wheel one notch in a clockwise rotation. Check belt tension again. The belt should experience no more than 1" deflection when depressed toward the inside (Figure 8-1). 1 . Disconnect power to the unit. 2 . Remove the front panel, rear access panel and the front weight (See Front Panel & Rear Access Removal). 3 . From the rear, locate the belt adjustment wheel and note the adjustment number aligned with the rib of the outer tub. This will help later when the belt adjustment wheel is placed back onto the outer tub and the belt is remounted on the motor and drive pulley. Remove the bolt securing the belt adjustment wheel (Figure 8-2). 16008373-01 SECTION 8. MOTOR DRIVE SYSTEM © 1998 Maytag Corporation 8-1
