This drive coupling has reverse threads. You must turn it clockwise to unscrew from motor shaft. This part is used on Blenders.
This part works with the following brands: Whirlpool, Admiral, Estate, Inglis, Kenmore, KitchenAid, Roper, Maytag, Crosley, Jenn-Air, Hardwick, Magic Chef, Amana, Caloric & Glenwood.
This part fixes the following symptoms:
First I inserted a small diameter rod in the motor fins to keep the motor from turning. Then I simply loosened the coupling. (Please know this is a left-hand thread). The coupling was not that tight. New coupling only requires a snug hand -tightening. You are are good to go!

My first step in repairing the broken KitchenAid blender, was to politely inform my wife HOW & WHY the blender broke in the first place. She thanked me for that, so she would know for the future. (whew...)Replacing the drive tooth wheel was a cinch. We who are reading this are all fortunate to have others, before us, fill us in on the details. I'm glad I read previous testimonials instead of banking on KitchenAid's instructions. Although the motor shaft is a left-hand threaded mount, the mfg's instructions said to remove the defective coupler by prying the wheel off in various positions with a 1/2" screwdriver!! Reading previous repair stories here, proved to be more reliable.It took more time for me to find a tool to aid in the removal of the old part, than it was to replace the part itself. I needed to find something that was thin enough to fit around the motor shaft and hold it from turning while I unscrewed the defective coupler in a "clockwise" direction. I eventually found a small, old pair of adjustable wire strippers. I was able to wiggle them in and barely grab the motor shaft. I turned the coupling clockwise and it came right off. No problem at all. Turns out that all that was probably needed was to insert a small punch between the motor fan blades through the bottom of the unit just to keep the motor from turning. The new fitting doesn't have to be on any more than hand tight, as the blender runs in a clockwise rotation, and will keep the fitting snug all the time.Good luck, home mechanics.
I slid a cheap, stamped-steel 7.5 mm bicycle wrench under the coupling - into the grooves on the shaft - and held the shaff so that the coupling could simply be unscrewed. (backwards thread) Took less than 60 seconds to make the entire repair. No prying, no problems.
Inserted a very thin (approx. 3/32") open-end wrench into the gap between the old coupler and the base of the blender to engage two flats on the drive shaft and hold the shaft from rotating. Grasped old coupler with adjustable pliers and turned clockwise to loosen and unscrew. Threaded the replacement part back onto the drive shaft and patted myself on the back for a job well done.Other people's repair stories were extremely valuable -- alerting me to the fact that the coupler has a left-hand thread and that the shaft has flats ground on it to engage a very thin open-end wrench. The only advice I can add to others' stories is that you can use a bench grinder to slim down a wrench which is too thick to fit into the gap between the coupler and the base housing. I already owned a set of so-called "ignition" wrenches, and all the sizes up to "1/4" were thin enough to fit into the gap. But the 9/32" wrench (which was what I needed) was just a a little bit too fat. Grinding down the head to fit into the gap was the most-time consuming part of the repair.
The drive coupling on my Kitchen Aid Blender shattered into dozens of pieces. Found this website and realized I could buy a new one. Could not remove coupling base with "official" instructions. However, user comments on how they removed coupling base very helpfull. Put thin blade screw driver thru hole on bottom of blender base, held the blade from turning and twisted the coupling base off. Very easy and quick. New one when on just as easily.
I have to disagree with several other feedbacks. The instructions included with the part direct the user to "pry" the old attachment plate off the drive shaft. Because the plate is made of aluminum and the shaft is steel, this took about 1 minute to accomplish with absolutely no damage to the shaft. It took about 30 seconds to install the new part. It took longer to clean up than it had to perform the repair and I didn't need to find and/or make any special tools.
Old coupling was harder to get off than I anticipated from reading the other repair stories on your site, but those reviews gave me encouragement to keep trying. Using the screw driver under the coupling as instructed, I lifed up on the coupling but had a very hard time getting it to budge. After many tries it eventually came off, but the rubber and metal parts of the coupling had separated by that time. No damage done. I cleaned off the shavings before installing the new part, as instructed, and had no more problems at all. To test the repaired blender I then made a batch of margaritas. Success! My problems getting the old part off might have been partly because I' m 77 yrs. old, female (less strength to gein with) with arthritis in my hands, BUT I DID IT! Thanks!
The coupling simply screws on to the base. The only difficulty is holding the shaft still to break the coupling loose. You need a thin wrench which I didn't have so I had to grasp it with needle nose pliers. Remember the coupling has left hand threads.
1)removed remains of the rubber2)bent the metal so the pliers had room to hold the pin3)hold the pin w/pliers4)while holding pin unscrew the copling5)screw new copling6)done!
I wasn't expecting a package when the part arrived LESS THAN TWO DAYS AFTER I ORDERED IT! I had my own idea about how I was going to replace the old coupler, which involved rigging a clamp to hold the shaft etc.I read the instructions that came with the part and couldn't believe how simple it was. The female threads on the coupler are aluminum (soft) and the threads on the driveshaft are steel(hard) so it can be simply pried off with a screwdriver. I love it when brute force is the right way to fix something. The new coupling screwed on with a left hand thread, no problem. I was somewhat disappointed that I didn't get to the day tinkering, but for the price of a movie I got a new blender.Part Select exceeded my expectations.
Our blender is about two years old. My son was making a smoothie and must have not seated the glass carafe down correctly, because after he was done, all of the plastic teeth on the drive coupler (on top of the base) were sheared off and scattered on the countertop. I was about to throw the thing away and spend another $125 on a replacement blender. After an internet search, I found the replacement part at PartSelect for $8.00. I watched their online video on how to switch out the drive coupler and realized how easy it was. The part arrived three days after I ordered it. In a little more than 15 minutes of gentle prying with a screwdriver, I had removed the old coupler and hand tightened the new one on the drive spindle. I had my son christen the new coupler with a smoothie. Worked perfectly.
With a flat bladed screwdriver I pried off the existing rubber of the old drive coupling. The old coupling was dry and hard and I believe this is the reason it broke. Left on the drive shaft is an aluminum piece with reverse threads. It is impossible to remove this without a very flat wrench (which I didn't have). I took my screwdriver and carefully pried upward from the underside of the aluminum piece, turning the piece as I went, and prying in each side. It seems scary to do this, but the drive shaft is quite strong and I was careful not to damage the edge of the blender. After doing this 8-10 times and gradually deforming the edge of the aluminum piece (bending up a few millimeters each time) the piece turned freely. I was able to unscrew (remember reverse threads) and put the new drive coupling on. Very easy fix and glad I didn't run out and buy a set of flat wrenches.
The directions discribing how to remove the drive coupler i thought implied that you needed to unscrew the coupler. The first part of the directions discribed the the coupler was threaded counter clockwise and needed to turn clockwise to remove te coupler. The step by step directions discribed how to use the screw driver to lift the coupler then turn 1/4 turn then use the screw driver again. After a few tie trying to turn the coupler by hand and with a pair of pliers I realized that the couple was made out of a soft metal and was actually bending away from the drive shaft. once that was accomplished the rest of the directions made sense.
First I lifted the container off the base, stuck a screw driver up through the bottom of the base to hold engage the motor blades so I could, by turning counterclockwise, disingage the broken coupling, Much easyer than prying it off as directed by the instruction sheet that came with the part. Very simple operation and saved me the cost of a new food processor. Thank you
I used a flat screw driver and gently and forcibly removed the part as recommended in the instructional manual. Putting the replacement part was not at all difficult. With the new part in place the blender now works like new.
