8.4 ENGINE: FAN BELT - DIESEL ___________________________________________
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 (B) 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 with a load 10Kgf (98N/22lbs).
3. Re-tighten bolts.
CAUTION
The anti-freeze can damage your skin. Use gloves when you use anti-freeze. If anti-freeze touches your
skin, clean the area immediately.
Discard anti-freeze in accordance with local regulations.
