Nancy for Model Number KSB5WH4 Rubber coupling completely crumbled while using the blender. The metal piece holding coupling is still in place. Did this occur because it is old? Can this be repaired? Thank you
Answer Hello Nancy, This part WP9704230 probably failed because of age and can be replaced. Since it has left handed threads, it will need to be turned clockwise to remove and counter-clockwise to install. You should be able to insert a small open-end very thin 9/32" or 7 mm wrench between the coupler and power base onto the motor shaft to hold the motor from turning during its' clockwise removal.
