Refrigeration & Air Conditioning USCG Question #171 (Set 3)

In addition to the drive belt itself, a V-belt that is tensioned too tight will cause excessive wear to what other drive component?

Official USCG Answer & Rule Citation

Correct Answer: Option B — motor shaft and compressor main bearings

Excessive V-belt tension places abnormal radial loads on the drive shafts. This over-tightening accelerates friction and wear on the motor shaft bearings and the compressor main crankshaft bearings.
