Generator drive belt maintenance
Correct belt tension is extremely important for the function of the generator and the operational life
of the belts themselves. The lifespan of the drive belts is affected by belt tension.
■ Slack V-belts can cause belt slip and damage to the belts.
■ Over-tight belts stretch and wear quicker. Over-tight belts also place unnecessary stress on
bearings and shorten their life.
