Checking the V-belt
Every 500 operating hours.
51 Checking tension
• Check tension of the V-belt by applying
moderate finger and thumb pressure. If the
deflection of the belt is more than 12 mm
(1/2”), using about 10 kg (20 lbs) thumb
pressure, it should be tensioned.
52 Tensioning V-belt
• Loosen the bolt of the adjustment bracket
and both the alternator mounting bolts.
Now push the alternator outwards until the
belt tension is correct.
• Now first re-tighten the upper mounting
bolt of the alternator.
• Then re-tighten the bolt of the adjustment
bracket and the lower mounting bolt.
53 Reinstall the protection cover
• Always reinstall the V-belt guard onto the
engine.
