Question

the following condition is an indicator of improper v - belt alignment. excessive bearing and belt wear extended belt wear increased productivity less downtime

Explanation:

When v - belt alignment is improper, it causes uneven forces on the belt and the bearings. This leads to excessive friction. Excessive friction results in more wear on both the belt and the bearings. Extended belt wear (option 2) is less likely as improper alignment usually causes faster wear rather than extended (in a positive sense). Increased productivity (option 3) and less downtime (option 4) are positive outcomes which are not associated with improper v - belt alignment.

Answer:

Excessive bearing and belt wear
