The most common symptom is that the blender motor runs, but the blades inside the jar do not spin or turn very slowly. You may also notice a burning rubber smell or see visible damage, such as stripped teeth or cracks, on the black rubber coupling located on the blender base.
Yes. This coupling features reverse threads, which means it is designed to tighten during normal operation. To remove the old, damaged coupling, you must turn it clockwise—the opposite of a standard screw. You can hold the motor shaft steady with a flat-blade screwdriver in the slot at the top of the shaft while turning the coupling clockwise to unscrew it.
You will typically need a flat-blade screwdriver to hold the motor shaft in place and a pair of pliers or a spanner wrench to grip and turn the coupling. The process is straightforward and usually takes less than 10 minutes.
The coupling is designed as a sacrificial part. It is made of rubber to protect the more expensive blender motor from damage if the blades become jammed by frozen fruit, ice, or thick ingredients. Over time, the rubber teeth can wear down or strip, requiring a replacement to restore the connection between the motor and the blade assembly.
