To Install New Main Door Glass

Remove main door assembly from dryer (follow main door removal procedure).

Lay main door on flat surface with front of door face up. Remove the four #10-32 Acorn nuts.

Remove glass and clean all old sealant off main door. This area must be completely cleaned for correct bonding.

Apply a narrow bead of silicone (ADC P/N 170730) all around main door area where glass will rest.

Install glass onto door/adhesive and slightly press glass in place.

IMPORTANT: Do not press hard or silicone thickness between the glass and door will be reduced, resulting in poor bonding.

Secure the four #10-32 Acorn nuts to hold the glass.

The door assembly should now be put in an area where it will not be disturbed for at least 24 hours. Depending on the conditions, the curing time of this adhesive is 24 to 36 hours.

After 24-hour curing period, install main door on dryer by reversing the first step.

To Replace Front Panel

Discontinue electrical power to the dryer. Remove main door switch and bracket assembly. Follow procedure for removal of main door assembly. Open control (service) door.

Remove lint drawer and open lint door by removing six screws.

Unplug the door switch wires at the bottom of the front panel.

Disconnect the wires connecting the “EMERGENCY STOP” (E-Stop). The easiest place to do this would be in the left hand electrical box. Once the wires are disconnected, push them through the inner top.

Remove the twelve Phillips head screws securing front panel to dryer.

Pull wires up through front panel door switch wire channel and gently remove front panel assembly.

Reverse this procedure for installing new front panel. Reestablish electrical power to the dryer.

Pulleys

To Replace Drive Shaft Pulleys

Discontinue electrical power to the dryer.

Remove the lint drawer. Remove the lint door. Remove right lint coop wall.

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

Remove cap screws from the bushings.

Insert cap screws in tapped removal holes and tighten evenly until bushing becomes loose on shaft. Refer to figure “A.”

Remove bushing, pulley, and key.

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

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

Tighten cap screws progressively. There should remain a gap between the sheave hub and the flange of the bushing.
