HARNESS AS 1195642 - Caterpillar

The V-belt must be tensioned correctly. Failure to tension the belt properly could damage the belt and/or to the belt guide, or water pump bearing.Do not allow the belt to come in contact with any foreign substance such as oil or grease as damage to the V-belt may occur.
For maximum engine performance and maximum utilization of your engine, inspect the belts for wear and for cracking. Check the belt tension. Belt slippage will decrease the belt life. Belt slippage will also cause poor performance of the alternator and of any driven equipment.If new belts are installed, recheck the belt adjustment after 5 minutes of operation. If two belts or more are required for an application, replace the belts in belt sets. If only one belt of a pair is replaced, the new belt will carry more load. This is because the older belts are stretched. The additional load on the new belt could cause the new belt to break.
