8 MAINTENANCE & LUBRICATION
8.3 ENGINE: FAN BELT ____________________________________________________
Check And Adjust The Fan Belt
The fan belt tension is adjusted to prevent the stress on the
alternator bearings and to prevent movement on the
alternator pulley. Use the procedure shown below to check
the belt tension at the center of the belt between crank shaft
and alternator pulleys.
1. Loosen the alternator bolt (A) and the pivot bolt below
the alternator.
2. Move the alternator to tighten or loosen the belt. A
deflection of 7 to 9 mm is needed at the center (B)
with a load 10Kgf (98N/22lbs) for a new belt. A
deflection of 8 to 10mm is needed for a used belt.
3. Tighten the bolts.
