5-1. ALTERNATOR DRIVE BELTS MAINTENANCE
a. I n s p e c t i o n .
This task covers inspection of alternator drive belts. Perform
drive belt tension check after every 500 hours of loader operation.
TOOLS: Drive belt tension gage (FSCM 45225 PN CAS-1441)
MATERIALS/PARTS: Clean cloths (Appendix C, item 1)
PRELIMINARY PROCEDURE: Engine left rear side panel removed (page 9-14).
Wipe dust and dirt from drive belts with clean cloth.
Check belts for evidence of grease or oil contamination.
Inspect belt edges and fabric for cracks,
frayed condition and deteriora-

Check for missing or damaged belt cogs.
If drive belt tension gage is not available in following step, check for
1/2 inch belt deflection midway between alternator and crankshaft pul-
l e y s.
(5) Measure tension of each belt using drive belt tension gage midway between
fan and crankshaft pulleys as shown. Belt tension gage should indicate 90
pounds for used belt.
If drive belt tension gage is not available, check
for 1/2 inch deflection midway between alternator and crankshaft pulleys.
