Question

which of the following can be caused by misalignment of drive pulleys?
a) belt chunking.
b) wear on the sides of the belt.
c) small cracks.
d) all of the above

Explanation:

Misalignment of drive - pulleys can cause uneven stress on the belt. Belt chunking occurs due to excessive and uneven forces. Wear on the sides of the belt happens as the misaligned pulley causes the belt to rub against components. Small cracks can also develop over time due to the abnormal stress distribution. So all these issues can be caused by pulley misalignment.
