To maximize the engine performance, inspect the belts for wear and for cracking. Replace belts that are worn or damaged.For applications that require multiple drive belts, replace the belts in matched sets. Replacing only one belt of a matched set will cause the new belt to carry more load because the older belt is stretched. The additional load on the new belt could cause the new belt to break.If the belts are too loose, vibration causes unnecessary wear on the belts and pulleys. Loose belts may slip enough to cause overheating.To accurately check the belt tension, a suitable gauge should be used.

If the tension of the belt is below 250 N (56 lb) adjust the belt to 535 N (120 lb).If twin belts are installed, check and adjust the tension on both belts.Adjustment
