40 Tensioning V-belt
• Inspect the belt for wear and tear (fraying and cracking). Belts which are in poor condition should be replaced.
• 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.
• 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.
Danger Check, tension and change belts only with the engine off. Refit belt guard, if provided. 62
• Then re-tighten the bolt of the adjustment bracket and the lower mounting bolt.
