Run your fingers alongside the floor of the pulleys to detect any roughness or unevenness. Worn or tough surfaces can improve friction between the belt and pulley, inflicting untimely put on and overheating.

Step 6: Examine the Pulley Bearings

If potential, test the pulley bearings for any play or looseness. Defective bearings may cause the pulleys to wobble or misalign, which might adversely have an effect on the belt’s efficiency.

Step 7: Examine the Pulley Hub

Study the pulley hub for any cracks, bends, or deformations. A compromised hub can weaken the pulley and improve the danger of catastrophic failure.

Step 8: Examine Pulley Offset and Runout

Utilizing a dial indicator, measure the offset and runout of every pulley. Offset refers back to the lateral displacement of the pulley from the middle of the shaft, whereas runout measures the variation within the pulley’s rotation.

Acceptable Offset Acceptable Runout
Lower than 0.020 inches Lower than 0.005 inches
