First, I watched the video provided by AppliancePartsPros.com. It was incredibly helpful to know that it’s a left handed thread. I took a flat head screwdriver and stuck it all the way through the bottom of the blender and into the cooling blades of the motor. Doing this, I was able to grasp the Coupler with my hand and, turn it to get it loose. Then it just spun right off. I replaced the new part and tightened it with the screwdriver still in place. The whole process took 45 seconds and most of that time was spent looking for a screwdriver.
