How to adjust the tightness of the fan belt of diesel engine
May 17, 2022
The adjustment of the fan belt of the diesel engine should pay attention to check that the front ends of the belts of the three pulleys of the crankshaft, water pump and generator are on the same plane. The appropriate belt tightness is: press the belt with a force of about 10kg, and the pressing amount is 10mm-15mm.
The adjustment of the fan belt of the diesel engine is achieved by adjusting the relative position of the generator, that is, loosening the fixing bolts that fasten the adjusting arm of the generator, and pulling the adjusting arm up or down to tighten the belt.
The appropriate belt tightness is: press the belt with a force of about 10kg, and the pressing amount is 10mm-15mm. When adjusting the fan belt, you should also pay attention to check that the front end surfaces of the three pulleys of the crankshaft, water pump and generator are on the same plane and cannot be twisted back and forth. The twist of the belt is mainly caused by the looseness of the fastening bolts of the generator and generator bracket.
In addition, check whether the generator and water pump bearings are loose and abnormal noise. Once this phenomenon occurs, the cause should be identified and dealt with in a timely manner according to the fault situation.
