To Replace Tumbler Pulley (Reversing)

Reversing

1. Loosen V-belts, then rotate pulley and roll V-belts out of grooves.

2. Remove cap screws securing taper lock hub to pulley.

3.Insert cap screws in tapped removal holes and tighten evenly until bushing becomes loose in pulley. Refer to Figure “A.”

4.Remove bushing, pulley, and key.

5. Assemble bushing and pulley as shown in Figure “B.” When cap screws are loosely inserted, bushing remains fully expanded to provide a sliding fit to the shaft.

6.Insert key on the shaft, then slide pulley to desired position with cap screw heads to the outside.

7.Tighten cap screws progressively. There remains a gap between the pulley hub and the flange of the bushing.

IMPORTANT: Tighten screws evenly and progressively. Never allow the pulley to be in contact with the flange of the bearing. This gap should measure from 1/8” to 1/4”. Proper cap screw torque is 30 ft.-lbs. (4.14 kg-m), if greater tightening forces are applied, excess pressure will be created in the hub of the mounted pulley which may cause it to crack.

To Replace The Rear Tumbler Bearing

1.Remove tumbler pulley (follow tumbler pulley removal procedure).

2.Remove the four (4) bolts securing the bearing box to the back of the dryer.

3.Loosen set screws securing bearing to shaft.

4.Pull bearing box and bearing off of shaft.
