How to Examine Belts and Pulleys
Examine belts and pulleys as explained below.
With power removed:
• Look for dirt, dust, oil, and grease. Remove contamination.
• Look for belt damage as shown in Figure 7 .
• Look for worn pulleys as shown in Figure 7 .
With the machine in operation—Do not touch the machine. Look and listen:
• A belt can have some vibration and not cause damage. It is necessary to correct this
condition only if the vibration is large.
• A belt must have sufficient tension that there is no slippage on the pulley during operation.
If slippage occurs, you can usually tell from the noise.
