Yes, 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

How can I change the blade for my 2 speed hand mixer? The model type is NC-12 if you need to know


you are using your KitchenAid blender and it stops blending, you may think there is a problem with the motor in your machine. However, a common reason for the blades not rotating in the blender is a dirty or faulty coupler. The coupler is what connects your blender dispenser to the motor, and you can easily replace the coupler at any time by only using a screwdriver.
Things You'll Need
  • Flat-blade screwdriver
    • 1 Turn the blender dispenser clockwise and lift up to remove it. Set the blender dispenser aside.
    • 2 Insert a flat-blade screwdriver between the black drive coupler and the frame of the blender on the top center portion of the blender.
    • 3 Lift the screwdriver upward, and the coupler will start to bend out of place. Slightly turn the coupler and then lift up on the screwdriver again.
    • 4 Continue to move the coupler slightly and lift the screwdriver until the coupler is completely removed.
    • 5 Insert the new coupler over the blender's motor blade and then twist the coupler counter-clockwise until it is tightly fastened.

Seems like motor has lost power


This sounds like the black rubber coupler has broken. The teeth often get knocked off. Have a look at the part shown in hte pictures here:

Rubber wheel that blade goes on, how do I replace it?This is the wheel that makes the blade go around. Mine has broken into pieces and can not use blender.


The piece that you need is referred to as the coupler. The coupler is a breakway part that is designed to shear and/or wear down in the event that the blender is overloaded. This is to avoid damage to the motor.

The coupler may be purchased individually and is an easy repair that can be done at home. You may purchase the part and access step-by-step replacement instructions at the following link:

Square drive pin for Osterizer blenders?


I simply slid a small screwdriver in through one of the holes under the base to prevent the fan from spinning and unscrewed the pin counterclockwise using some small channel lock pliers. No disassembly necessary.

Replacing the part that connects the motor to the blades on an Oster blender


I don't know if this will help or if this is what you are looking for. But today I was searching the web for the bottom piece that fits on the jar and saw this website has a lot of replacement parts for Oster blenders. Hope this is what you're looking for.
Good Luck

Rubber coupling


Yes.

The coupler - the black cylindrical piece that juts up from the motor base, and it has 6 teeth protruding inward toward the center of it - is responsible for transferring motion from the motor into the blade assembly. You physically set your jar on top of it.

If you're needing a replacement coupler for your blender, you may order it and find repair instructions at the following link:

Top part of base broke off


This just happened to me too, and I think I just fixed it.  First you have to get a replacement part called the "blender coupling" (I got mine online from Goodmans for $3.99).  I also replaced the square drive and slinger (two parts come together for $2.99)-that's the little part that sticks up and attaches to the pitcher.
Unscrew the bottom four screws of the base where the rubber feet are.  Remove the rubber skirt to reveal four screws that hold the motor in.  They are way in there so you'll need a long screw driver.  Remove the motor and unscrew the old coupling.  Mine had not been replaced since my grandmother bought this blender who knows when, so the coupling was really stuck.  I did not have a tool narrow enough to get a good grip to apply enough torque to remove the coupling so I had to try a few other tricks.  If your blender is the same, remove the bottom nut, fan blade and two washers.  This gave enough of a rod to grip to get the old coupling off.  (I also had to use some WD40, and heat and cool the coupling a few times to break the old seal).
Good luck!  Hope that helps!
