The North Benz heavy truck water pump is one of the important components of the automobile engine cooling system. The role of the North Benz V3 accessory water pump is to ensure the circulating flow of the coolant in the cooling system and accelerate the heat dissipation by pressurizing the coolant. As a long-term operating device, the water pump of Beiben Heavy Truck will also have faults during use. How to repair these faults? Many people will think that such inspection is very complex, and if the fault occurs, they can directly report for repair. In fact, there are some small faults that can be completely solved by the owner, and do not need to spend "wrong money". If the water pump of the North Benz heavy truck breaks down or is damaged in use, the following inspections and repairs can be made.

1. Check the pump body and pulley for wear and damage, and replace them if necessary. Check whether the pump shaft of Beiben heavy truck is bent, whether the journal is worn, and whether the shaft end thread is damaged. Check whether the blades on the impeller are broken and whether the shaft hole is seriously worn. Check the wear degree of the water seal and bakelite washer, and replace it with a new one if it exceeds the service limit. Check the wear of the bearing and measure the clearance of the bearing with a meter. If it exceeds 0.10 mm, replace the bearing with a new one.

2. After the pump of Beiben heavy truck is taken out, it can be disassembled in sequence. After disassembly, the parts shall be cleaned, and then checked one by one to see if there are cracks, damage, wear and other defects. If there are serious defects, they shall be replaced.

3. Repair welding is allowed when the pump body has the following damage: cracks with length less than 3 mm and not extending to the bearing seat hole; The flange connecting with the cylinder head has a broken part; The oil seal seat hole is damaged. The bending of the pump shaft of Beiben Heavy Truck shall not exceed 0.05mm, otherwise it shall be replaced. The impeller blades should be replaced if damaged. The hole diameter of the pump shaft of the North Benz V3 accessory is severely worn, and it should be replaced or repaired with a sleeve.

4. Check whether the bearing of Beiben heavy truck water pump rotates flexibly or has abnormal noise. If there is any problem, replace it.

5. Repair of water seal and seat: if the water seal is worn and grooved, it can be polished with abrasive cloth. If it is worn too much, it should be replaced; If the water seal seat has rough scratches, it can be repaired with a plane reamer or on a lathe. Replace the water seal components with new ones during overhaul.

6. After the assembly of the pump of the North Benz V3 accessory, rotate it by hand, and the pump shaft is free of seizure, and the impeller and pump casing are free of friction. Then check the displacement of the pump of Beiben Heavy Truck. If there is any problem, check the cause and eliminate it. If the water pump of the Beiben heavy truck fails, the coolant will not reach the corresponding place, and its performance will not be effectively developed, thus affecting the working condition of the engine. Therefore, it is necessary to strengthen the inspection of the pump of Beiben heavy truck.
