Drive Belt Replacement Or Adjustment

COMPARE MEASURED FORCE TO

RECOMMENDED FORCE

Compare the deflection force measured, to the

value shown in the table.

For new belts the value for run-in should be used. For belts, which have been running two days or more, use the values for normal running.

ADJUST THE BELT TENSION

Adjust the sliding motor base to increase the belt tension by turning the adjusting screws clockwise.

When the tension has been increased significantly, recheck it using the procedure just described.

Repeat the process of adjustment and tension checks until the allowable deflection is achieved while the deflection force is within the range shown in the table.

Tension new drives at the maximum deflection force recommended.

Check the tension at least two times during the first two days of operation. There is normally a rapid decrease in tension until the belts are run in.

Check the tension periodically after the first day of operation and keep the tension in the recommended range.

The correct operating tension for a V-belt drive is the lowest tension that allows NO belt slip under peak load conditions. If the deflection is more than the specified deflection at the recommended force, tighten the belts. If the deflection is less than the specified deflection at the recommended force, loosen the belts.

TIGHTEN THE MOTOR BASE BOLTS

Tighten down the motor mounting bolts.
