Let's analyze the abnormal noise of the water pump of the water sprinkler truck for you. What's the problem with the noise?

First, if the impeller of the water pump is broken or worn out too severely, the impeller of the water sprinkler truck's water pump needs to be replaced. It is recommended to carefully check if there is any abnormal noise from the water pump, as malfunction of the auxiliary drive shaft or power take-off connected to the water pump can also cause abnormal noise. For instance, if the drive shaft is deformed, or if the gears inside the power take-off break or the bearings fall apart, it will all cause abnormal noises.


The following are the methods to eliminate abnormal noises at the water pump of the water sprinkler truck:

First, turn on the power take-off of the water sprinkler truck to make the water pump and the drive shaft work. Lie under the vehicle and observe whether the drive shaft is shaking to see if there is any problem with the drive shaft. Secondly, if there is no problem with the drive shaft, remove the drive shaft, open the power take-off, and let it idle to check if there is any abnormal noise when the power take-off idles. This way, it can be determined whether the power take-off is faulty. If there are no issues with the power take-off and the drive shaft, then the problem lies with the pump.
