How to Change a Washing Machine Pulley

Jul 10, 2023, 15:35pm

With wear, the pulley of a washing machine is likely to warp or twist. This is the kind of wear that will cause the belt to jump and therefore render the washing machine unusable.

If there are noises when the drum turns, it is a symptom that the pulley is damaged. It is therefore necessary to change it.

The pulley is located on the tub of the washing machine. It is connected to the motor by a belt. Access to the pulley will be from the rear for a porthole washing machine and from the side for a top washing machine.

The pulley in a washing machine plays a vital role in the drum’s movement, enabling it to spin and agitate during a wash cycle. However, over time, the pulley may wear out, become damaged, or develop faults that can affect the machine’s performance. In such cases, it may be necessary to replace the pulley. This guide will walk you through the steps to change a washing machine pulley.

Safety Precautions

Before starting any repair work on your washing machine, it is important to prioritize safety. Always unplug the machine from the power source before attempting any repairs. Additionally, ensure you are working in a well-lit area and wear protective gloves to prevent injury.

Tools Required

To change a washing machine pulley, you will need the following tools:

  • Screwdriver set (Phillips or Torx, depending on your machine)
  • Adjustable wrench or pliers
  • Towels or rags (to protect the floor and clean up any spills)

Steps to Change a Washing Machine Pulley

Follow these steps to change the pulley in your washing machine:

Step 1: Unplug the Washing Machine

Ensure the washing machine is disconnected from the power source by unplugging it from the wall socket.

Step 2: Access the Pulley

To access the pulley, remove the back panel of the washing machine using the appropriate screwdriver. Set the screws aside in a safe place. You should now have a clear view of the pulley and drive belt.

Step 3: Release Tension on the Drive Belt

Using an adjustable wrench or pliers, locate the tensioning mechanism near the motor or drum pulley. Loosen the tension on the drive belt by either rotating the tensioning pulley or releasing the tensioning screw. This will relieve the tension and allow you to remove the drive belt from the pulley.

Step 4: Remove the Pulley Nut

Using an adjustable wrench or pliers, loosen and remove the nut securing the pulley to the motor or drum shaft. Place the nut in a safe place where it won’t be lost.

Step 5: Remove the Pulley

Once the nut is removed, carefully slide the pulley off the shaft. In some cases, the pulley may be secured with a retaining clip or screw. If so, remove the clip or screw before sliding the pulley off.

Step 6: Install the New Pulley

Take the new pulley and slide it onto the shaft, aligning it properly. Ensure it sits flush against the motor or drum surface. If necessary, refer to the old pulley or consult the user manual for guidance on the correct orientation.

Step 7: Secure the Pulley

Place the pulley nut back onto the shaft and tighten it securely using an adjustable wrench or pliers. Ensure the pulley is held firmly in place.

Step 8: Reattach the Drive Belt

Route the drive belt back onto the pulleys, following the manufacturer’s recommended path. Use the tensioning mechanism to apply tension to the drive belt, ensuring it is tight enough to prevent slipping but not overly tight.

Step 9: Reassemble the Washing Machine

Once you have completed the pulley replacement, reassemble the washing machine by placing the back panel back in its original position. Use the screws you previously removed to secure the panel tightly.

Step 10: Test the Machine

Plug your washing machine back into the power source. Turn it on and run a test cycle. Observe the pulley’s performance and listen for any unusual noises. Ensure the drum spins smoothly and evenly. If the machine operates correctly without any issues, it indicates that the new pulley is functioning properly.

If you encounter any persistent problems or suspect a fault in the pulley despite the replacement, it is recommended to consult a professional appliance repair technician or contact the manufacturer for further assistance.

In conclusion, changing a washing machine pulley is a relatively straightforward task that can be done with some basic tools. By following these steps, you can replace a faulty or worn-out pulley and ensure the smooth operation of your washing machine. Always refer to your washing machine’s user manual for specific instructions and guidelines, as different models may have slight variations in the pulley configuration. Regular maintenance and prompt pulley replacement will help prolong the life of your washing machine.
