What should be checked first after replacing belts on a V-belt drive before running it?

Before running a V-belt drive after replacing the belts, the first step should be to ensure that the belts are placed properly over the sheaves. Proper alignment is crucial for the efficient operation of the drive system. Incorrect placement of the belts can lead to misalignment, which can cause excessive wear and tear, reduce the efficiency of power transmission, and potentially lead to catastrophic failure of the system.

Checking the alignment of the belts ensures that they are seated correctly in the grooves of the pulleys (sheaves), which is essential for optimal performance and longevity of the belts and the overall drive system. If the belts are not positioned correctly, it may result in slippage, vibration, and increased friction, leading to premature failure or damage to both the belts and the pulleys.

While checking the tension of the belts, their condition, and the pulleys are also important steps that should be performed, verifying the correct placement is the priority to ensure that the drive system functions properly and to prevent further issues from arising during operation.
