5KSB52BBU5 KitchenAid Blender - Instructions

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.

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.

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

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

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

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.

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

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.

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

I used a pair of diagonal cutters to nip away at the drive coupling which had become gummy and soft. This exposed the inner aluminum hub that the drive coupling was molded to. I used several pieces of masking tape to protect the blender finish under the drive coupling. The instruction supplied suggest to pry upward with a screw driver at 1/4 turn intervals until it comes off the motor shaft. I thought this was a rough approach, as I was concerned about damaging the threaded motor shaft. Also note that the motor shaft has left handed threads, you would turn clockwise to loosen the drive coupling. The first approach I tried was to use a small ignition wrench, there are two flats directly below the coupling aluminum hub which measured 9/32" across the flats. The wrench even though small would have to been ground thinner to fit, this may have worked. I decided to use approach two. I used my dremel tool with a 1/32" cut off wheel and cut through each side of the aluminum hub staying away from the center where the motor shaft is threaded. Across the center of the hub I only cut through half the thickness, I then used the diagonal cutters to fold each half agains itself (the hub actually fell off). I installed the new coupling turning it counter clockwise on the motor shaft. I attached the blender jar filled with water with the jar lid on and toggled the blender on and off a few times to further tighten the drive coupling.

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

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

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!
