KSB5WH3 KitchenAid Blender - Instructions

simple clear instructions to follow

I couldn't unscrew the old coupling (left hand thread) so I carefully sawed a piece off being careful (the somewhat difficult part of the job) not to damage the threads on the drive motor. Then I used pliers to remove the rest of the drive coupling. Then it's just a matter of screwing on the new coupling. Good as new and I didn't have to buy a new $150 blender.

I just followed the instructions to remove the old drive coupling and screwed in the new one.

Hardest part was taking off the old coupling. I locked the drive with a thin wrench and pryed the coupling off. Took about ten minutes to get off and two minutes to put the new gear on. Remember the thread is counter clockwise. PartSelect was great the part arrived in two days.

using the screw driver I pryed up on the old coupling as out line in the instructions that came with the part. The old part cam off easily and the new one just screwed on. The replacement took only a few minutes.

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

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

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.

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.

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 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

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.

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
