How to Adjust Fan Belt Tension of Diesel Generator Set

When the fan belt of the Deutz generator used by the customer is too loose, slipping will cause the rotation speed of the fan and pump to decrease, thereby affecting the heat dissipation performance of the generator set. If it is too tight, the wear of the shaft and bearings will be aggravated. Therefore, the fan belt of the generator must maintain normal tension to ensure the normal operation of the cooling system. Then, which generator set maintenance method can adjust the fan belt to ensure that the diesel generator set has appropriate tension? You can adopt this method:

1.Loosen the large lock nut on the diesel engine fan or the screws that fix the fan to the mounting bracket.

2.Rotate the adjusting screw to increase the belt tension.

3.Tighten the lock nut or screws until the fan is aligned. Tighten the nuts to keep the diesel engine fan and fan bracket properly aligned. Note: Do not use the adjusting screw to adjust the tension of the diesel engine fan, otherwise it will cause it to be too tight.

4.Tighten the lock nut on the engine to 400-450 foot-pounds [542-610 Nm], then loosen it by 1/2 turn backwards.

5.Recheck the tension of the diesel generator belt.

6.Loosen the adjusting screw by half a turn to prevent damage.

After mastering the correct adjustment method, it must also be told to everyone that if the air storage tank temperature is not high, stop checking and adjusting the tightness of the fan belt; severely worn or broken fan belts should be replaced in time. In addition, if your diesel generator has two fan belts, both belts must be replaced at the same time to avoid uneven tension, which may lead to equipment failure.
