Adjusting Belts

Check condition and tension of all belts after first day of
operation and every 200 operating hours thereafter. Raise
bed (if so equipped) and position safety support on
extended lift cylinder to hold up bed.
Alternator belt
1. Check tension by depressing belt at mid span of
crankshaft and alternator pulleys with 22 lbs. of force.
A new belt should deflect .3–.5 in. A used belt should
deflect .4–.55 in. If deflection is incorrect, proceed to
next step. If correct, continue operation.
2. To adjust belt tension:
• Loosen (2) alternator mounting bolts.
1. Alternator
• Using a bar, rotate alternator until proper belt tension is
attained, then tighten mounting bolts.
Fan belt
Check belt for wear, cracking or improper tension.
Important
increased steering effort.
1. Check tension by depressing belt at mid span of fan and
drive shaft pulleys with 22 lbs. of force. A new belt
should deflect .48–.58 in. A used belt should deflect
.55–.65 in. If deflection is incorrect, proceed to next
step. If correct, continue operation.
