A blade on my immersion blender was bent slightly. The motor still works and the blades spin, but they no longer emulsify. Can I buy just a new blade attachment?

match it up at any hardware store

I have a 9090 I am selling (all blades) including wall rack. If interested let me know.

I don't have one, but inspect the shaft, it looks like there is a key on the shaft, then inspect the inside of the blade where it goes on top of the shaft, see if it looks like the shaft has spun out the blade and this is why it's not spinning.

Remove the blade and the container, then turn on and see if the shaft is spinning, it should be most are a direct drive.

So now if the shaft is spinning, that most likely means that the blade hole is broke where it sets on top of the shaft.

Look closely at the inside of the blade, you should see some type of damage like the groves are worn, I hate to see you buy one and it was the shaft that wore, but usually the blade will go first.

As stated earlier it could be the shaft needs lubing, remove the bottom part of the blender blade... the rubber thing that engages on the motor. I started with WD-40 and worked some lithium grease into it. Spins like new now.

mine just broke as well the hand blener is working but the piece on top of the inside lide broke off so as not to make a good attachment with handle where can i geta lid

Does the motor still work if you take the pitcher off of the base? If so, the rod that's in the blade assembly is probably corroded. The blades are connected to a metal rod that passes through a brass tube through to the piece that makes contact with the motor when you put the pitcher on the base. The grease wears down eventually and if you don't pulse and run the motor for a long time at once, the heat can corrode the bar and cause the blade to stop spinning. You can either disassemble the blade unit, or buy a new blade unit online. google blender parts and you can get one for $10

your blade assembly is corroded. take it off, and using a rag, grab the blades. using another rag, grab the other end (probably rubber) and turn CLOCKWISE - it's threaded reverse, so you have to turn to the right to loosen, not the left like usual. I had to clean out the rod that connects to the blades - it was all nasty and corroded. I cleaned it with my Dremel and regreased with a tube of grease I keep in the garage, cleaned all other parts with some Dawn, dried well, reassembled, and works almost like new. I'm guessing I ran it too long without pulsing the motor and the heat corroded the rod that's connected to the blades. OR you can buy a replacement blade unit for about $10 online on a blender parts site

Replace the blade assembly immediately. They are available from Cuisinart's website. Sugars and other stuff can gum up the blade assembly over time, so it will periodically need to be replaced. A quick and easy way to keep the blade assembly clean and working longer is to put water and a drop of dishwashing soap in the blender after use and run the blender at low speed for 15-20 seconds - an old Osterizer trick.

I had this problem and, after seeing these posts, was motivated to avoid paying the cost of a new blade unit. Here's how it can be fixed:
1. Take a kitchen hotpad and hold the blade (top) side of the unit in your hand as you unscrew the rubber gear on the base. This is a left-handed screw, so you must turn it clockwise, to free it up. This should be doable by hand. Be careful, removing the gear exposes a washer note which side is up, and place both the gear and washer aside.
2. With the blades held in the hotpad, unscrew the top nut, again clockwise. This takes more effort, but it will eventually give way. As this nut comes off, it exposes a rectangular post, to which everything is attached.
3. Remove a washer with a rectangular cutout. Make sure you remember which side is up (I think it makes no difference). This may require some rocking to remove the washer from the round-threaded end. It will come off.
4. Remove both blades in a similar manner. Note their orientation, which is important.
5. Next, remove a rubber gasket. On mine, it has a groove which is asymmetric. I don't think the orientation is important, but, again, you may want to note it.
6. What is left is an axle inside a sleeve. There are no bearings. In mine, I had to tap/drive this out. Take a flat-ended rod (ideas: I used the hex-shaped post end of a nut socket. An old drill bit you don't care about, rotated would also work). Place the unit on the edge of the counter, up-side pointing up, in a way so the bottom end of the axle could fall free when you drive it out. Gently tap the axle through the unit, using the helper tool when the axle is within the sleeve. It will drive completely out.
7. Clean everything. I simply scrubbed the axle and took a small brush to the inside of the sleeve. This doen't need to be perfect, but anything left on either surface may ultimately impair the functioning of the axle.
8. Lubricate the axle with household oil or a dab of grease. You will find that the axle will now slide into the sleeve fairly easily (I had the best luck from the top.)
9. Reattach the base gear, then the top in the obvious order. Everything should spin freely from this point on.
REMEMBER: always use the hotpad whenever you grip the blades and to tighten the bolt on top so that the axle protrudes slightly above the nut.
Good luck!
