To Replace Main Door Hinge Blocks
1. Discontinue electrical power to the dryer.
2. Follow procedure for removal of main door assembly.
3. Disassemble bottom hinge block from front panel by removing the Allen head screws located inside the hinge
block.
4. Reassemble by reversing removal procedure.
5. Reestablish electrical power to the dryer.
F. PULLEYS
To Replace Tumbler (Basket) Pulley
1. Loosen V-belts. Rotate pulley and roll V-belts out
of grooves.
2. Remove cap screws from the bushings.
3. Insert cap screws in tapped removal holes and
tighten evenly until bushing becomes loose on shaft.
Refer to figure “A.”
4. Remove bushing, pulley, and key.
5. Assemble bushing and sheave as shown in figure
“B” on page 26. When cap screws are loosely
inserted, bushing remains fully expanded to provide
a sliding fit on the shaft.
6. Insert key on the shaft, then slide sheave to desired position with cap screw
heads to the outside.
7. Tighten cap screws progressively. There should remain a gap between the
sheave hub and the flange of the bushing.
IMPORTANT: Tighten screws evenly and progressively. Never allow
the sheave to be drawn in contact with the flange of the
bushing. This gap should measure from 1/8” to 1/4”.
Proper cap screw torque is 30 ft-lbs. (41 Nm). If
greater tightening forces are applied, excess pressures
will be created in the hub of the mounted sheave which
may cause it to crack.
