Your machine is equipped with the following belts:
1. Matched set of fan and alternator belts.
2. Brake system compressor belt.
3. Air conditioner compressor belt (if machine is equipped with air condi-
tioning).
Fan Belts
Check the matched set of engine fan belts after every 500 hours of opera-
tion. If too tight, the belts can cause rapid wear of alternator and water pump
bearings. If too loose, the belts may slip, wear fast, and permit engine over-
heating and battery run-down.
Belt Tension
Properly adjusted fan belts can be depressed
1/2
inch (12 mm) midway
between the fan pulley and the crankshaft pulley. A belt tension gauge, used
between the two pulleys, should give a tension reading of 110 pounds (50 kg)
on a new belt, and 90 pounds (41 kg) on a belt that has been run-in. To tighten
belts, loosen the adjusting bolt at the strap on top of the alternator, and swing
the alternator away from the engine. When adjusting belts, pry against pulley
housing only.
