Service Procedure 5-1
Inspecting, Adjusting & Changing
the Main Drive Belt
The main drive belt requires only minimal maintenance and normally lasts many years
with normal use.
Inspection
The belt should be inspected yearly. Replacement is indicated if any of the following
conditions are found:
1) Excessive slack that cannot be corrected.
2) Frayed or badly worn edges.
3) Missing or damaged drive lugs on the belt surface.
Adjustment
CAUTION: Overtightening the belt will cause the belt to jump on the wormshaft
pulley and will cause the saddle bearing nearest the pulley to become excessively
hot.
Adjusting slots to tension the drive belt are provided in the motor mounting plate.
Adjust in the following manner:
1) Unplug the processor from its power outlet.
2) Loosen the four motor mounting plate screws. These are accessible on the back
of the processor, below the dryer.
3) Slide the motor until the belt has approximately 1/2" of play. With no racks in
place, you should be able to rotate the driveshaft with your fingers approxi-
mately 1/8" back and forth.
4) Tighten the four screws.
5) If most of the slack cannot be removed, the belt is worn excessively and should
be replaced.
Replacement
The following procedure is to be followed when replacing a worn drive belt:
1) Unplug the processor from its power outlet.
2) Remove all four racks (dev, fix, wash & dryer) and carefully set aside.
3) Loosen the four drive motor mounting plate attaching screws on the rear of the
processor. Move the motor to remove the drive belt.
4) Remove the cotter pin holding the drive belt pulley to the driveshaft.
5) Slide the driveshaft pulley forward far enough to allow removal of the belt
around the end of the driveshaft.
6) Install the new belt in the reverse order.
7) Adjust the new belt as described above.
