Title: How to fix a shattered blender drive coupling of KSB5
Review: I tried to make a date smoothie and the metal blade jambed, but the motor kept going. when I took off the glass container I found that that vulcanized rubber blender drive coupling had shattered. I was able to chip the rubber away to reveal that inside it there was an aluminum disk. This was attached to a shaft sticking out of the casing. the shaft had flattened facets on each side which I gripped with thin wire cutters, and using a channel lock wrench turned the disc CLOCKWISE (this thing was reverse threaded). This revealed the threads at the end of the shaft. Then we ordered Modle # 9704230 from gourmet depot.net. We will hand tighten that by turning counter clockwise and running the blender should automatically tighten it. Good luck
