The black rubber that blender sits on is breaking off.

Hello, Carla -

For all electric blenders the rubber gasket is placed between the glass or plastic blender container and the rotor with the blades.

The assembly is easy to recall when one realizes the rubber gasket is the seal for keeping liquids leaking out of the blender.

See the image here (it's for a Black and Decker, but the assembly is the same):

The image here shows the assembly for a Waring blender (different model than yours):

Best wishes.

I have not seen the drive gear made available. You could try making an inquiry with either of the above sites to see if they can locate a replacement. Alternatively contact a local small appliance repair shop; they may be able to scavenge the part from another blender.

It is very easy to fix. You will need a new coupler, which is part number 9704230. There is a set of instructions with video here:http://www.kaparts.co.uk/Howtoremoveablendercoupler/tabid/219/Default.aspx The part is available on Amazon as well as many other sites.

I did the same thing. Order parts at thegourmetdepotco.com -- This problem is caused when you put the rubber gasket underneath the blade instead of above it. This causes two problems: 1. It lifts the teeth on the jar away from the teeth on the drive gear, which can grind down and break off the teeth, and 2. If the drive gear contacts the rubber gasket, it will melt the rim of the drive gear. In the future, to reassemble the jar after cleaning, first put the rubber gasket on the jar, then the blade, lastly screw on the base ring.

The rubber gasket should go between the blades and the jar.

You can most likely find all kind of blender parts at www.thegourmetdepotco.com. I just bought a Krups blender rubber drive gear from that online store. It's the best lowest price, compared it to Amazon.com too. Try it.
