Question edited for clarity, name of maker.Question moved from Cars and Trucks.The company handles these as Blendtec now. The web site is at
http://www.blendtec.com/default.aspx Maybe this will help:Customer service and sales are available from 8:00 am to 5:30 pm (MST) M-F.I just talked with Blendtec about this issue, since I had the same problem. I asked if there was a stronger drive shaft since my previous Kitchen Champ model had a different, sturdier drive shaft that lasted about ten years.The company representative explained that the new drive shaft
is designed to break, but that's to save the motor. If the stress on the drive shaft could damage or cause excessive wear to the motor, the drive shaft breaks instead.She also recommended using just enough flour so that the bread dough pulls away from the sides of the bowl. The reason most drive shafts experience too much stress is due to too much flour in the recipe.To replace the drive shaft, go to
http://www.blendtec.com/Parts.aspx or call Blendtec at 1-800-BlendtecThe only part that will work for the Kitchen Champ is the Drive Shaft (Champ). Apparently, the German drive shaft -- which looks like the one from my old Kitchen Champ -- is not interchangeable.Since this is my second Kitchen Champ and my previous one lasted over ten years, I'm delighted to understand what went wrong. I'm hopeful that using less flour will prevent another problem. And, I'm very pleased with how helpful Blendtec was, explaining this to me.All taken from here.
