This is a Cuisinart Food processor. The blade has been on and off many times, but lately has been difficult to remove. Now, it seems to be stuck on the shaft, big time.
I used a large pair of pliers to attempt to pull up on the plastic center core of the blade. I tried to pry the blades up from the bottom, I tried lifting the plastic basket to pull up on the blade.
Nothing has worked. Is it possible for a vacuum to form between the motor shaft and the blade? If there was dampness inside the blade core, could that cause a vacuum? Will the vacuum eventually disappear or should a hole be drilled in the plastic core of the blade to break a possible vacuum?
Are there any special tools recommended for removing the blade?

Re: Food processor blade stuck on motor shaft
My friend if you had not removed that blade for a while it will certainly stuck due to the moisture that forms on the shaft of the blade holder causing it to have corosion you will have to carry that item to be removed by a qualified tech by you doing it your self could cause damage,which could cost you more.good luck

If the unit works OK with other attachments and the problem is only with the one cup; then the blade may be loose and spins on the shaft, the connection gear under the bottom is worn or binding up. Debris is stuck around the blade shaft or from heating up the metal parts expanded and bind when turning.
My old Cuisinart has this problem because the motor shaft and the corresponding socket on the cutter are worn. The shaft has jammed in the cutter. To un-jam it, stick a bar of wood behind one blade of the cutter (I use the wood handle of my dough whisk) and give it a light, sharp tap with a hammer. Check after every tap to see if it is loose, if not do it again. You want to tap against the back side of the cutter, not the cutting edge side. The socket on your cutter may be cracked, allowing it to open up and slip (and jam) under the stress of cutting. You'll probably need a new one. If the motor shaft is also worn, that can also be replaced. The new part is about $10. I got a few more months of life from my cutter by reinforcing the inner socket with a thin plastic tube from the barrel of a syringe.
it is either the seal around the blade shaft that is worn (but if it is worn so much that liquids can leak, then you probably heard the machine vibrate more than normal or sound screechy). Or it is the gasket at the bottom of the container that is not seated well or is out of shape. Goodluck, Macgivor
I had the same problem: Cuisinart sent a "replacement" sheath for my DLC-8E which turned out to be the wrong one. When I replaced mine,which was cracked, none of my blades would fit over the new sheath! I "solved" the problem by purchasing a new DLC-8E motor base on Ebay for only $9.99!
I phoned the 800 number at Cuisinart (800-243-8540) and the person who answered the phone explained to me what to do: Fill the bowl with the hottest tap water I have (but not boiling) above the entire blade (including the part that fits over the shaft). He said to pulse a few times, then try to pull it off, but not to expect it to work right away. He said to do this until it comes off and that it could take 1/2 hour. I did what he said, and the blade came off after the first pulses. But also, the water was pouring out all over the counter--leaking between the bowl and the base (possibly because my old work bowl is also cracked, but I'm not sure).
I was told that the problem would happen again, and that I needed replace the blade and the shaft (which is cracked, as he guessed), both of which are available from Cuisinart.
On the DLC 7 Pro cuisinart the blade was removed by removing the plastic bottom. Make sure the unit is unplugged. Remove the four rubber pads on the bottom. This was the hardest part because the pads are glued so securely that the inner rubber surface tears as it's removed. I used two flat blade screwdrivers and worked carefully, back and forth. Using a #2 philips, remove the four screws. Place the unit on its side and while inserting a screwdriver between a spoke and the motor frame gently turn the blade counter clockwise. Be careful not to put pressure against the cooling fins. Very little pressure was needed and the blade came right out. I might have been able to hold the shaft from turning without removing the bottom, by going through the vent slots in the bottom, but I was concerned with cracking the plastic. To replace the rubber pads I matched the design of the torn rubber pad with the shape (design) of the surface glued rubber and used thin two-sided tape.
If the blade is actually fused, I would seek professional help to avoid slicing your fingers off. You can test to see if it is fused by removing the lid of work bowl, twisitng work bowl to the left, and removing the work bowl - if work bowl will not come off (difficult even under normal circumstances), then find out from Cuisinart if you are still under warranty.
Had the same problem. The Cuisinart folks said to fill it with hot tap water - not boiling - then turn it on and off. The heat from the water will unstick the bowl. If it doesn't work first time - refill with hot water and try again. Worked like a charm for me.
