KSB53 KitchenAid Blender - Instructions

The part comes with instructions on how to replace the coupling. The instruction basically says to pry out the worn coupling. This is exactly what you should do. It might sound strange or brute force but it actually works. The coupling is actually made of some soft metal that comes out easily. The only downside is that you have to clean up the leftover metal bits. You don't need to find a slim wrench for the motor spindle as suggested by other in the thread ..... just follow the instruction pry out the old coupling.

Removed reverse thread coupler, jammed screw driver into fan blade at bottom of mixer, installed new coupler. REMEMBER, REVERSE THREAD!

Just as the provided instruction says, pry-off old coupling than screw on the new. This repair was too easy! This blender was out of commission a long time, it is good to have it back in use.

I looked on the Web for help in changing this part they suggested prying the part off with a screwdriver. This would work but I figured this approach was a little to brutal.I had a set of distributor wrenches and these had one that fit the shaft under the drive coupling Using the wrench to hold the shaft I used a small set of water pump pliers to remove the coupling.As the directions on the Web states this is a reverse thread.The whole project took all of five minutes to complete

I utilized the "pound the coupling in a clockwise direction" to loosen the coupling. Two good "wackes" and it was loose. Installed new coupling. I found this method in the previous customer installation instructions on the site. Please note that my new part number is ps401661. This part works normally even though my model number did not list a part number, perhaps because my blender is an older model. Without the installation instructions site I would not have known that the thread was a "reverse thread". This site is very helpful. Good luck

Just took a screwdriver and pried off the broken coupling as the instruction said with the part. Don't stress it really works and is easy. Ordered the part on Monday and recieved it on Tuesday. Great service from Partselect!

Very easy. Enclosed instructions were excellent! Part arrived early than anticipated, also.

Remove blender jar to get to drive cog. Use a 1/4 to 3/8 flat open-end wrench to hold cog shaft then turn the cog with your hand CLOCKWISE to loosen. Screw new cog gear on COUNTERCLOCKWISE hand tight. Reassemble your blender and you're good to go. It takes a very thin flat wrench but even if you have to buy a set the're not very expensive. Good luck.

Thanks to the good advise of those who did this before me ,I know I need a very slender wrench to get between the screwed on base of the coupling and the copy of the base of the blender.
I tried to file one myself, but the metal was too weak. Because i had the size (from what I filed), I measured and knew i needed a 7 MM wrench. I bought one at the parts store and ground it thin enough to slip into the small space and from there it was a five minute job.

A very flat wrench or needle nose pliers was needed. I could not get the nut unscrewed with what I had so I had to mail the unit to a service center for repair. They were able to use the part I had purchased but if I had known I wouldn't be able to do it I could have saved a little money in the shipping I had to pay when I ordered the part.

Tried to follow the included instructions - no way that just prying the coupler off would work without bending the shaft and wrecking the threads! Then used a flat, open-ended 7mm wrench to hold the shaft and pliers to remove the coupling. The coupler was so tight that I could not unscrew it without the wrench slipping. Ended up shoving a screwdriver through the fanblade from the bottom (unplug it first!) and use the pliers to unscrew the coupler (remember, it's a left handed thread!)

it need a special tool...to remove the broken coupleing..had to have my brother-in-law who fixes industrial equipment, remove it with a special tool, that a home owner would not have

Directions included with replacement part were no help...maybe I'm stupid, but prying up on a threaded metal part didn't help unthread it at all.
Vise grips solved the problem. I used vise grips to remove the rubber from the coupler while it was still attached to the blender base, exposing the metal base to the coupler. (yes, I used vise grips to destroy the damaged coupler. after all the hell I went through to try to do it as the directions said, it was very satisfying.)
After removing the rubber, I used the vise grips to bend and distort the metal base until I could get a pair of needle-nose pliers around the drive shaft and hold it still while I unscrewed the now bent-up metal base. Victory!
I thoroughly recommend this method to anyone else, as using vise grips to destroy something is very gratifying.

Read provided instructions but unfortunately looked at part and re-interpeted the instructions....Should have just followed instructions as printed. I tried to pry up and unscrew instead f just prying off...

Followed instruction sheet, but as it stated just remove by hand, not so, had to grind open end wrench to fit between coupler and base to fit flat sides of shaft, then use channel locks to break lose and to unscrew most of the way off.
But in the end the part worked just fine.
