Is your blender making sounds but the inside is not spinning? So when you take off the glass jar and confirm that a black “clutch” is spinning, yet when you put the jar back in with food, nothing happens? Then this article is perfect for you.
I have owned this Cuisinart BFP-703 for well over 12 years and it has been a workhorse.
To its testament of durability, Cuisinart still makes this exact same model!
So I was sad when I went to make smoothies for my kids one morning and it would not chop at all. Upon closer inspection, I discovered that this little black clutch has a hairline crack.
Even though the clutch was cracked, it had just enough “bite” so that without any weight on it, it would spin.
Thankfully, this clutch is a replaceable part. The bad part was that Cuisinart did not sell this part (I guess they want you to buy a new blender instead).
Well, Amazon.com to the rescue! Cuisinart SPB7-20TXN Blender Blade Driver Clutch fits perfectly to BFP-703 blender.
You might want to consider picking up a spare one or two because it is designed exactly the same (molded plastic around brass screw), my guess is that the blender will outlast the clutch.
No special tools are required for this project:
- Phillips screwdriver that was longer than 5″ or so (base screws are in deep seated holes).
- Adjustable Pliers (don’t have one? see my review here)
- Flat or slotted screwdriver (multiple sizes)
STEP 1 – Disconnect the power cord from the outlet
STEP 2 – Lay down the blender on its side and remove three Phillips screws from the bottom
STEP 3 – Carefully separate the base from the top (top unit has the motor
STEP 4 – Remove the rubber bushing that is loosely attach to the bottom of the motor
STEP 5 – In order to remove the broken clutch assembly, you actually have to break off the plastic part. Using a small plastic flat screwdriver, carefully work around the hairline crack to pop it off
STEP 6 – With clutch removed, you can remove the motor assembly from the housing
STEP 7 – While firmly gripping the brass nut with an adjustable pliers, use a flat head screw driver to turn the bottom screw, located at the bottom of the motor. The brass nut thread is reversed so you will need to turn RIGHT OR CLOCKWISE to unscrew the brass nut
STEP 8 – Reinstall the motor back into the housing
STEP 9 – Screw on the new clutch
STEP 10 – While holding down the new clutch with your finder, tighten the motor screw on the bottom
STEP 11 – Finally, reinstall rubber bushing back on the motor, adjust kraft paper if necessary and re-attach the base
That’s it! Now you can go back to making smoothies for your kids!

if the brass nut thread is reversed wouldn’t you want to turn it clockwise to remove?
yup, your are correct.
reverse threads or left-handed threads are loosened by turning clockwise as opposed to common right-handed threads that are tightened by turning clockwise.
it has been corrected. thank you!
Awesome info , saved me about a 100.00 ! Thanks !
great! thanks for sharing!
I appreciate this information, so I want to share my experience. I removed the bottom to gain access to the screw head at the bottom of the shaft. I popped off the plastic top to the clutch with two flat head screwdrivers.. This exposed the brass nut. I held on to it with vise grips. With a screw driver holding the shaft from turning, I turned the vise grips, removing the brass nut. I did not take the motor out.
Thanks Joe for sharing your information!
I have watched this video, I absolutely cannot get the brass nut off. I even had someone else try it with help from the directions. Any suggestions?
Tough situation. The suggestion is to buy or borrow a mini plumber’s pipe wrench with sharp teeth intact (like this one). Before tightening, make sure the teeth on the wrench face the opposite direction of turn to give it more “bite” and turn the thumbscrew on as tight as you can and turn. If that fails, you can try to drill it off using a Dremel but i think that is more trouble than its worth.
Let me know how it turns out!
What’s between the threads and the motor body?
I replaced the clutch, turned it on, and it ran a little while, then jammed. Opened it up again and removed the clutch, and saw that the bottom of the clutch was wearing away onto the shell. I also noticed a loose C-ring, and what looks like a thin split washer. I see a notch on the shaft where the C-ring could go, but I’m not sure if anything is missing. I tried putting the C-ring on the notch and reassembling it, but after a couple of minutes it jammed again.
If you look at fig. 4.3, you will see a black spacer then a locking c-ring on top.
It sounds like the clutch was defective. I would ask for a replacement
I guess we pick and choose what is published.
What do you mean?
Any tips on why the ON light is flashing and when I select a speed, the motor turns on for a second and then off?
This blender has a pulse mode (you power one, press pulse-which will make the power on light blink, then you must choose a mode (mixing) and hold the button down.
Are you doing this?
