KSB53 KitchenAid Blender - Instructions

I followed the instructions on the sheet that came with the replacement part. The instructions are accurate, however, the working is misleading. I think additional information is needed to make the install easier. First, a flat head screwdriver works best. Also, all the rubber that is on the broken coupling needs to be removed before trying to get the coupling off. Once all the rubber has been removed then it becomes easier to see the metal rod that holds the coupling and distance between the coupling and the base of the blender, take the screwdriver and gently pry the coupling off in an upward movement while going around in a circular manner. Then you can see the coupling rising up from the rod. Then take a hold of the broken coupling and pull it off. Then attach the new coupling, screwing it on counterclockwise. Once you realize what is going on, it's actually quite easy.

Went easy

I used a straight edge screwdriver. At first my husband and I were afraid to much too much force behind the old coupling, but I figured it's no good the way it was so used more force and "pop" it came off. Then installed the new one and I love my blender!!

Last time this happened we simply used a thin wrench to unscrew the damaged coupling. This time it was so tight no wrench could undo it. We had to grind it off using a grinder drill until it was so loose it popped off.

Went to several online blog sites. Repair of the Kitchenaid blender is a hot topic. Could not repair it the way the instructions indicated. One person used a hammer and that did the trick! Who would have thought to use a hammer?!

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.

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

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.

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

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

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

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

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.
