11. 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. If greater tightening forces are applied, excess
pressures will be created in the hub of the mounted sheave which may cause it to
crack.
To Replace Small Speed Reducing Pulley Shaft
1. Discontinue electrical power to the dryer.
2. Remove the lint drawer.
3. Remove the lint door.
4. Remove right lint coop wall.
5. Loosen V-belts, then rotate pulley and roll V-belts out of its grooves.
6. Remove cap screws from the bushings.
7. Insert cap screws in tapped removal holes and tighten evenly until bushing
becomes loose on shaft. Refer to figure A on page 25.
8. Remove bushing, pulley, and key.
9. 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.
10. Insert key on the shaft, then slide sheave to desired position with cap screw heads to the outside.
11. 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 6 ft.-lbs., if greater tightening forces are applied, excess
pressures will be created in the hub of the mounted sheave which may cause it to
crack.
To Replace Large Speed Reducing Pulley
1. Discontinue electrical power to the dryer.
2. Remove the lint drawer.
3. Remove the lint door.
4. Remove right hand lint coop wall.
