Brake System Compressor Belt
Check the air compressor belt every 500 hours of operation. If too tight, the
belt can cause rapid wear of water pump and compressor bearings. If too
loose, the compressor may not maintain full pressure in the braking system air
reservoir.
Tension Check
A properly adjusted compressor belt can be depressed
1/2
inch (12 mm)
midway between the fan pulley and compressor pulley. A belt tension gauge
should give a reading of 110 pounds (50 kg) on a new belt, and 90 pounds (41
kg) on a belt that has been run-in.
Adjustment and Installation
When adjusting belt tension, or installing a new belt, loosen the three bolts
underneath the compressor sliding bracket. Then slide the compressor in-
ward or outward as required and retighten the bolts.
