Mudder 5 Packs 9704230 Blender Replacement Parts with Wrench

Pay attention to the wrench! There are no instructions and I did not realize that it was a wrench needed to unscrew the old one. I pried the old with a flathead and nearly ruined the alignment of a 28-year old KitchenAid. This was my second or third time needing to do it but I forgot the process. Just pay attention to the opposite spin than a normal thread direction. I have been using this for several months a couple of times a week with no deterioration.

Couple of things, first if you have the K585 blender the included wrench will not fit between the base support tabs but this isn't the end of the world, simple take the other end of the wrench and grind the hole open (see pic) and you will be able to slide it in between the tabs to remove the old part. Now with that said the kit comes with 5 couplers. As you can see by the pictures the original part (left, picture 2) is much more substantial then the replacement (probably why you get 5) and is made of a hard plastic instead of the original hard rubber. An installation tip, when installing the new part place a dab of anti seize on the part before you install. This will allow the next time you need to replace this part much easier. My original lasted 20 years I really doubt the replacement will do as well but I now have 4 more and a wrench to easily replace it again when it fails. Anyway you look at it beats the heck out of $300 for a new one.

I’m so glad that I can actually change the part instead of changing the whole blender. The part appears to be as durable as the original, and it was a breeze to install. One thing to pay attention to is that the part is reversed threaded so tightening is actually loosening the part. 🙂

100% works. Kitchen aid blender. The tool worked the replacement parts were great.

After destroying the original part on my blender, I found these. They're nothing but a cheap piece of plastic and a prime point of failure for the blender, but thankfully these replacement parts are easy to install, and because they're likely to wear out like the original, buying them in small multiples is a good idea and not expensive.

This fit our kitchen aid blender very well. We seem to destroy the coupling every few years, so having spares on hand is good. Note that in some cases you can remove the old coupling using the "inertia" method (whack the gear sharply and rely on the inertia of the motor to hold the shaft still), but that doesn't aways work. It those cases the wrench is very handy.

First - Why does the coupler break in the first place? - one way to break it is by assembling the jug incorrectly after washing it. The rubber gasket has to touch against the glass... if the gasket is placed against the plastic side instead, the drive shaft will be too high for the coupler (it reaches it only with its fingertips) and it will break. The rubber gasket "looks right" in either position, but only the glass side is correct and checking it will keep the coupler alive for a long time! (Ask me how I know...) It is literally a 2 minute job to install a new coupler. You will need a pair of pliers (the Channelock type is perfect for this). The easiest way to remove the old coupler is to just slide the little wrench under the coupler on the blender, then grab the coupler with the pliers and turn it CLOCKWISE (turning right) to unscrew it from the shaft. Note that this is the opposite direction of normal screws! To install - just screw the new coupler on ANTICLOCKWISE (turning left) while holding the shaft with the wrench. Hand tight is enough as this thread is self tightening during use. As far the the product is concerned, the material and workmanship look and feel good - the blender works as new again.

I saw my wife about to throw out our KA blender. She said it was not working and there were bits of plastic at the coupler. Our unit is well over a decade old. I checked and indeed the coupler had perished (rubberized plastic). Luckily I looked on Amazon and saw this part was a typical failure and somewhat easy to replace. I ordered this pack - which had five couplers and the removal tool for the same price as many of the two packs. I have photos of the failed part and the new part. Fits well and works as the original. Will update on longevity if needed, but so far save my unit from the recycle bin! (And these units are pretty expensive). Note: as others have mentioned removal and install of the coupler is opposite to normal as the treads are reversed which is typical in rotation devices (so they don’t get loose with use) - such as circular saws and angle grinders too. I used the supplied tool and channel locks to get the old one off. Review as of Dec 2024.

Fit perfecty. Excellent value pack

I have used 3 of these already, as other users in the household (and me) will shred the part every few years. a very cheap way to keep your kitchenaid blender forever and saving it form landfill. worth it. every time. lots of youtube videos dedicated ot epxlaining, with variang degrees of clarity, how to do the installation. they are rigth, the aluminium part of the screw just rips off the strong steel component its attached to, without damaging the base unit. have fun out therein kitchenaid land...

Fast delivery, only two days. Replacing the blender coupling part was so easy, thanks to the included wrench. Will order again.

Pour ma part ,une chance que Amazon est la !! Un mélangeur de 300$$ aurait fallut en acheter un autre. Mais ils en avaient chez Amazon, merci beaucoup
