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.
G. TUMBLER (BASKET) ALIGNMENT
1. Discontinue electrical power to the dryer.
2. Remove the lint drawer.
3. Remove the lint door.
4. Remove both the left hand and right hand lint coop walls.
5. Loosen the V-belts on drive shaft, then rotate pulley and roll
V-belts out of its’ grooves.
6. Tighten the two (2) bolts under the drive shaft clockwise
(CW) to raise the tumbler (basket) and counterclockwise
(CCW) to lower the tumbler (basket). The bolts should be
tightened in even increments in order to ensure that the shaft
runs parallel with the base of the dryer.
IMPORTANT: Side to side adjustment of the tumbler (basket) should be equal on either side of the
front panel, but vertically the top of the tumbler (basket) should have a larger gap than
the bottom to compensate for the load.
IMPORTANT: Be sure to tighten the left idler side to the same height as the right side/drive side. This
length can be determined by taking measurements from the bottom of each pillow
block bearing to the top of the bearing pad.
NOTE: If the axle height is not the same on the drive and idler side, then the tumbler (basket) will be
either more to the right or left side, depending on which axle is higher.
7. Tighten locking nuts on the adjustment bolts.
8. Reverse Step #1 through Step #5 for reassembly.
9. Check tumbler (basket) drive belt for proper tension. Adjust if necessary.
10. Reestablish electrical power to the dryer.
