How To Change The Water Pump Belt?

In routine maintenance of mechanical equipment, replacement of water pumps and fan belts is a common task. The water pump belt is responsible for driving the water pump to ensure that the cooling system can work properly, while the fan pulley helps the cooling system maintain normal operation. In this article, MyMROmarts will introduce you in detail how to replace the water pump belt and how to remove the fan pulley from the water pump to help you better maintain your mechanical equipment.

 

How To Change The Water Pump Belt?

1. Cut Off The Power Supply Of Mechanical Equipment

Before performing any repair or replacement operations, ensure that the engine is turned off. Cutting off the power can avoid any unexpected situations.

 

2. Position The Water Pump And Belt

Position the water pump according to the model of construction machinery you are using. Typically, the water pump is located on the side of the engine and is connected to other cooling system components. Then, find the belt that connects to the water pump. Generally speaking, the water pump belt is usually located on the front of the engine.

 

3. Loosen The Tensioner Pulley

Near the engine water pump you can find a tensioner pulley. You can use a wrench to loosen the screw of the tension pulley counterclockwise to loosen the tension of the belt.

 

4. Remove The Old Belt

Remove the old belt from the water pump and other drive wheels. You may need to gently tug at the strap with your hands during this process to make sure it is fully disengaged.

 

5. Install New Belt

Guide the new belt into the drive pulley and water pump pulley grooves. Make sure the belt is placed correctly and do not allow the belt to cross or twist randomly.

 

6. Tight Adjustment

Adjust the belt tightness by rotating the tensioner pulley. It is generally recommended that the tension of the belt is not too loose and not too tight, and just maintain the appropriate tension.

 

7. Fix The Tensioning Wheel

When you have finished adjusting the belt, use a wrench and turn the tensioner screw clockwise to secure it.

 

8. Check The Working Condition Of The Belt

Finally, reconnect the power supply, and the starter motor start the engine, and observe whether the newly installed belt is working normally. Ensure that the belt does not twist, slip, or make abnormal noise during operation.

 

How To Remove Fan Pulley From Water Pump?

1. Cut Off The Power Supply To The Water Pump

The same principle as when replacing the water pump belt, you need to ensure that the power to the engine is cut off.

 

2. Locate The Fan Pulley

Locate the fan pulley near the water pump. It is usually closely connected to the water pump.

 

3. Loosen The Fan Pulley Screws

You can use a wrench to loosen the screw connecting the fan pulley counterclockwise. These screws may be a little tight and require some force to loosen.

 

4. Remove The Fan Pulley

Once you loosen the screws, the fan pulley will be free to remove. Please handle this with care and ensure your own safety.

 

Replacing the water pump belt and removing the fan pulley are important tasks in mechanical equipment maintenance. By following the correct procedures, you can ensure proper operation and extend the life of your engine and other diesel engine parts. If you are unsure about the operation, it is recommended to seek help from a professional master.
