I was thrilled that I was able to find this part so easily and with a delivery time of two days. The cleaning lady in my office was gone for a few days so I took the vacuum cleaner to clean when I realized it was missing a part! However. Make sure the racquet is lined up properly, the gear+ is aligned and properly lowered to the "far" side. The new part then fits the side you are dealing with and rotates perfectly into position. Another reviewer suggested that you check to see if there was a loose piece left on the racquet shaft by a broken piece during installation.
