Check and Adjust Fan Belt Tension
(ZX120-3, 180-3 Class)
--- every 100 hours (first time after 50 hours)
IMPORTANT: Loose fan belt may result in insufficient bat-
tery charging, engine overheating as well as
a rapid, abnormal belt wear. Belts that are
too tight, however, can damage both bear-
ings and belts.
Visually check the belt for wear. Replace if necessary. Check
fan belt tension by depressing the midpoint between fan
pulley (3) and alternator pulley (4) with the thumb. Deflec-
tion must be A with a depressing force of approximately 98
N (10 kgf, 22 lbf).
