You want to ask how to replace the dehydration barrel coupling of the washing machine? Remove the bottom case screws, loosen the two screws on the coupling, and then pull out the coupling.
1. Open the back cover of the washing machine first.
2. Remove the screws that fasten the motor brake wheel and the dehydration barrel.
3. There is a coupling between the barrel shaft and the motor shaft. There are two screws on the upper and lower opposite sides. Loosen the upper screws.
4. Remove the cover on the bucket and gently pull out the bucket to pull it out. The barrel and barrel shaft are molded and integrated into one component. Separating them will cause damage.
The washing machine coupling is a mechanical part used to connect the two axes in different mechanisms, the driving shaft and the driven shaft, to rotate simultaneously to transmit torque.
