4KSB5SSOB KitchenAid Blender - Instructions

used needle nose pliers to hold shaft after prying rubber top off. unscrewed metal tap, counterclock wise. installed new piece

Hammer was used to remove the old one, tapping quickly on old coupling. I did use a thin pliers (wire stripper) to hold shaft when I screwed on new coupling, even though it said one did not need to. Good instruction sheet came with the new coupling.

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

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.

Inserted the screwdriver under the original gear and pried it off. After that you just screw the new gear on, it has reverse threads so no tighting is required.

Took the coupler out with the help of screwdriver and put the new coupler. really easy fix insted of buying a new blender

popped off the old one, popped on the new one. could not have been any easier. :)

I used a screwdriver,pulled out the piece,then change with a new one,that I was ordered before.It was ver easy to assembly.

followed instruction, prying off old coupling and screwed new coupling on less than 5 minutes. Parts came in a timely manner. great service, satisfied customer

Since the coupling is threaded, it can be easily screwed on and off if you immobilize the shaft. If you don't have a tool that can do this (the space between the drive coupling and the body of the blender is only about 1/8"), you can insert a long bladed screwdriver into the vents on the bottom of the blender and into the motor. When you turn the coupling, the motor won't rotate and you can easily screw off the coupling (the threads are reversed, so turn the opposite way). Good luck!
Good

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.

Followed the video you sent removing the old drive coupling. Installed the new part according to instructions. I found I did not need to order the seal. I am a do it yourselfer and have never had such a good experience.

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

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