How to Fix a Motor Coupling for a Washer That Has Spinning Issues

If you have a top-load washer that won’t spin and you’ve been hearing a vibration, there may be a problem with the motor coupling. This part is located between the transmission and the motor on direct drive washers that do not have a belt. Normal use will create wear on the coupling and eventually the drive forks may slip and not engage the transmission and clutch. A common symptom of a failing motor coupling is that the washing machine fills and drains normally but will not agitate or spin.

What is a Motor Coupling?

Some top-load washers use a motor coupling to transfer power from the motor to the transmission. This coupling consists of two drive forks made of plastic, one attached to the shaft of the drive motor, and one attached to the input shaft of the transmission. Then there is a rubber coupling between them that protects the forks by absorbing the torque. Over time, the coupling can wear out and allow those plastic forks to slide and vibrate. The coupling can also get broken when the spin basket is impeded, or the transmission seizes.

Where is the Motor Coupling Located?

You will find the motor coupling located on the shaft of the transmission and on the shaft of the drive motor in your washer.

FIX TIP

Remember that before handling any electronic appliances to disconnect the power source from your appliance before beginning to avoid electrocution.

How to Access, Remove, and Inspect a Motor Coupling

1. To access it, you will need to disconnect the power and water supply, and then open your washer’s cabinet.
2. Once the cabinet is removed, you will want to place the washer on its back. You may also need to remove the drain pump and/or the motor, depending on your model.
3. With the motor out of the way, you can now access and remove the drive lugs from the transmission and the motor shaft.

How to Test a Motor Coupling

Normally, the easiest sign that your motor coupling needs to be replaced is that it's broken, or severely worn-out and no longer serviceable.

How to Install a New Washer Motor Coupling

1. Push the first piece of the new coupling onto the transmission shaft by tapping it into place, ensuring that it is flush.
2. Install the round piece of the coupling, and then reattach the motor bracket.
3. Tap the third and final piece of the coupling onto the motor, and then the motor can be reinstalled onto the transmission.
4. Ensure that the lugs on the coupling are inserted into the slots of the round piece.
5. With all the coupling pieces now connected, the motor can be clamped in place and the washer reassembled.
