ENGINE: FAN BELT

Check & Adjust Fan Belt.
The fan belt is adjusted so that it has sufficient
tension to avoid undue stress on alternator bearings
but does not slip on the alternator pulley. Use the
following procedure to check the belt tension at the
mid-point of the belt between crank shaft and
alternator pulleys.
1. Loosen alternator bolt (A) and pivot bolt on the
underside of the Alternator.
2. Move the alternator to tighten or loosen the
belt so that a deflection of 7 to 9 mm is
achieved at the mid-span (B) with a load 10Kgf
(98N/22lbs) for a new belt, and 8 to 10mm for
a used belt.
3. Re-tighten bolts.
