Drive Belt Replacement Or Adjustment

INSPECT THE DRIVE BELTS

Check the belts for cracks in the V-sections that ride in the pulley grooves as well as on the outside

surface of the belts. Also look for signs of excessive wear.

If replacement is necessary, continue with the steps that follow.

If it is not necessary to replace the belts, skip ahead to the step entitled Measure the Belt Span.

REMOVE THE BELTS

Loosen the motor mount locking screws.

Loosen the belt tension on the V-belts by turning the adjusting screws on the motor base counterclockwise- When the tension has been released sufficiently, slip the belts over the pulley and remove them.

If replacement of any V-belt is necessary, all belts must be replaced at the same time with a set of matched belts.

INSTALL THE MATCHED BELTS

Check the parts list to verify the part number of the correct belts.

Slip the belts into the grooves, one-at-a-time, making sure that the motor base has been adjusted enough to allow the belts to be installed without danger of overstressing them by forcing them over the edges of the V-grooves.

TIGHTEN THE BELT TENSION

Turn the adjusting screw on the adjustable motor base clockwise to increase the distance of the motor shaft from the rotor sheave. When the belts become snug, but not tight, stop the adjustment and use the procedure that follows to set the belt tension.
