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 .
