8.3 ENGINE: FAN BELT____________________________________________________
Check & Adjust Fan Belt.
The fan belt is adjusted so that it has sufficient tension to
prevent 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.
