Treva M Wapakoneta , OH June 03, 2015 My old kitchen aid blender drive coupler was completely shredded My son -in - law fixed it. I told him I would show him the instruction video. While I was looking up the video, he used a screwdriver and already had it repaired before I knew it. Blender works fine. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
