KSB-5 KitchenAid Blender - Instructions

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.

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.

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.

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.

I followed the advice of others who have written their story. It is very important that you know the coupler has a left handed screw pattern. I had to use pliers the entire process to unscrew the coupler and a screw driver through the bottom between the fan blades to hold shaft. I finally had to put the screw driver -gently- as far in as possible in a position that would hold the blade.

The shaft and the coupler are threaded. On could unthread the coupler. But many time it is frozen. The coupler is manufactured out of soft metal center and plastic. If frozen, it can be pried off the shaft using a large screw driver --- per the instructions provided with the part. This worked well with no damage to the blender power shaft. The new coupler was simply screwed on to the shaft and it works fine. The online schematics provided by PartsSelect helped me identify th part, part number and the nomenclature. The part arrive on the west coas in about four day --- very quick service. Thanks, PartSelect. Great job!!!

I followed the instructions included with the new part.I do admit that I needed decide to trust in the instructions , before starting the repair, and that took a lot of time and blind faith,,, I was very pleased with the deliberate design of the coupling that allowed a very easy fix. Fifteen minutes or less of tool time. I like it! Thank you, thank you, Ernst

first I unpluged the appliance, then using a thin blade 1/4 inch screwdriver I pride up the old coupler. when I had movved it just a litte bit, I tapped it with the handle of the screwdriver it came right off. the threads were clean so I screwed on the new coupler. plugged it in and it works like new. tme for repairs, around 10 minutes.

Followed the instructions included.

Nothing could have been simpler-I just inserted a flat bladed screwdriver between the coupling and the blender and pried up in about 3 different places. The old coupling came off and left no residue on the threads.

It took me longer to clean off the particles of rubber left on the blender from the old part crumbling than it did to replace the coupling.

Easiest appliance repair I've ever done!
