You likely need a new coupling if the blender motor is running but the blade assembly is not spinning, or if you notice a burning rubber smell during operation. Over time, the internal teeth of the coupling wear down, lose their grip, or strip completely, preventing the motor from transferring power to the blender jar.
Yes. This coupling features left-handed threads. To remove the old, damaged coupling, you must turn it clockwise. If you turn it counter-clockwise, you will only tighten it further.
The installation is straightforward and typically takes about 5 to 10 minutes. You will need a flat-head screwdriver to hold the motor shaft in place (often through a slot in the bottom of the unit) and a spanner wrench or a pair of pliers to grip and unscrew the coupling. Always ensure the blender is unplugged before beginning the repair.
