Belt Adjustment

CAUTION:

UNPLUG THE MACHINE BEFORE PERFORMING ANY ADJUSTMENTS. THIS PROCEDURE

MUST BE DONE BY A QUALIFIED TECHNICIAN.

Check the belt tension. The proper belt deflection is 1/2" over all. If the deflection is more than 1/2" the motor
will need to be lowered. If the deflection is less than 1/2" the motor will need to be raised. Follow this procedure
to adjust the motor to achieve proper belt tension.

1. Unplug the machine and remove both side and the rear panels.

2. Locate the motor flange bearings. These are the pillow block bearings that hold the motor to the cradle. The

motor is double shafted and the shaft extends through a bearing on each end. The bearing is held to the motor-
cradle by two allen bolts on each bearing.

3. Loosen the allen bolts on each bearing. Do not loosen the setscrews that hold the bearing collar to the

motor shaft.

4. Lower the motor or raise the motor as needed. The motor must be kept level from front to back. Do not

lower or raise only one end of the motor. This will result in excessive belt wear and belt noise.

5. Tighten all four allen bolts down. Align the motor pulley with the top pulley if needed.

6. The motor pulley should be in alignment with the large (driven) top pulley. Use a straight edge along the top 

pulley.

7. If the pulleys are not in alignment, remove the setscrew from the motor pulley and move either in or out as 

needed.

8. Reinstall the setscrew. Use non-permanent loc-tite on the setscrew and tighten it back down on the motor

shaft. Please be sure the setscrew is tightened down flat on the motor shaft.

9. Return the unit back to service.
