Which installation process may shorten the life of a belt?

Forcing or prying a belt onto a pulley can significantly shorten the life of the belt due to the stress it places on the material. When a belt is not installed properly and requires excessive force to fit, it may create uneven wear or result in damage to the belt's structure. This can lead to premature failures, such as cracking or tearing, because the belt was not meant to be stretched or manipulated beyond its design limits during installation.

In contrast, aligning the pulleys correctly is crucial for ensuring that the belt operates smoothly and within the intended parameters of its design, thereby promoting longevity. Using a proper size belt that matches the specifications reduces the risk of excessive wear or slippage, contributing to a longer life. Adjusting tension post-installation is a standard practice to maintain optimal performance, ensuring the belt is neither too loose nor too tight, both of which could affect its service life.
