TIGHTENING THE FAN BELT: Fan belts tend to loosen after the first 50 hours of operation. If the fan belts are loose, the engine can overheat and the bat- tery can lose its charge. Check belt tightness by press- ing on the belt midway between the pulleys. The belt should deflect no more than 10 mm (0.375 in.). See Figure D.6.
To adjust the fan belt, do the following:
1.See Figure D.6. Loosen the pivot fasteners of the alternator (1) and the adjustment link fasteners (2).
2.Change the position of the alternator to give the cor- rect tension. Tighten the pivot fasteners of the alter- nator and the adjustment link fasteners.
3.Check the belt tension again to ensure that it is still correct.
If a new belt is fitted, the belt tension must be checked again after the first 25 hours of operation.
