Engine Maintenance 9-31
BELT TENSION ADJUSTMENT AND BELT REPLACEMENT
NOTE: Belt tension specifications are measured using Thermo King belt gauge tool, (P/N: See tool catalogue)
Belts should be regularly inspected during unit pre-trip for wear, scuffing or cracking and correct tension.
Correct belt tension is critical for correct unit operation. Belts that are too loose will slip, squeal or whip causing excessive
vibration levels and poor unit performance. Belts that are too tight will put too much strain on the belt fibres and bearings, causing
premature belt and bearing failures.
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 will fail
prematurely due to internal cord damage.
WARNING: DO NOT jump belts on by cranking the engine. Personal injury may result.
WARNING: DO NOT attempt to adjust belts with the unit operating.
WARNING: CYCLE-SENTRY Equipped Units with the CYCLE-SENTRY switch in the CYCLE position and unit On/Off
switch in ON position, the unit may start operation at any time without prior warning. Switch unit On/Off switch to OFF
position before performing maintenance or repair procedures.
