Adjusting
1. Loosen the adjusting plate bolt and the
mounting bolt.
2. Insert a bar between the alternator and the
cylinder block to move the alternator to obtain
the required belt deflection.
3. Tighten the mounting bolt and the adjusting
bolt.
CAUTION
• If the fan belt is too tight, excessive stress is
put on to the fan bearings and belt, which
might shorten the life of both. If it is too
loose, it will slap against the pulleys, causing
unnecessary wear and tear to the belt, which
could cause possible slipping, to the extent
that the engine will overheat.
• Keep the belt free from oil or grease.
