• Loosen the adjustment bolts (3).
• Pivot the alternator away from, or towards
the engine, to increase, or reduce tension.
• Tighten the UPPER adjustment bolt (3).
• Tighten the LOWER adjustment bolt (3).
• Tighten both bolts (2).
• Connect the battery, run the engine for five
minutes at a fast idle and then switch off.
• Re-check belt tension.

Check the belt deflection with thumb pressure,
mid-way between the steering pump and
alternator pulleys (arrowed (1) in illustration).
Movement should be between 4 and 6 mm
(0.16 and 0.25 in). If adjustment is necessary;
• Turn the starter switch to position ’0’ and
disconnect the battery negative lead.
• Slacken the adjustment link clamp and
pivot bolts (2).
• Slacken the two alternator pivot bolts (3).
