Belts
Belts should be regularly inspected during unit pretrip inspections for wear, scuffing, or cracking. Belt tension should also be checked during scheduled maintenance inspections. Correct belt tension is critical for correct unit operation. Belts that are too loose will whip and belts that are too tight put too much strain on the belt fibers and bearings.
New belts should be tensioned cold and re-tensioned cold after 10 hours of unit operation.
Note Do not attempt to remove or install belts without
loosening adjustments. Belts that are installed by prying over pulleys
will fail prematurely due to internal cord damage.
