4KSB5 KitchenAid Blender - Instructions

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.

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 inserted a metal rod in the bottom of the base while I held it sideways to keep the motor from turning and I used pliers to twist the coupling off counterclockwise.
I thought at first I was doing it wrong because it wouldn't nudge so I left it alone. I then read the repair stories again and went back to it and it right came off. I guess there was a lot of gunk holding it tight.
Of course when the new one came days later it was easy to twist it on. Thank you for all of your stories. They were very informative and encouraging. Without them I'm not sure if I would have attempted it myself.

Following the instructions which was quite clear.

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!!

Simply to find the look of dismay in her face. After I violently began shaking and dismantling the compactor in disgust. I decided to unplug it from the wall, I then gathered my senses and began to perform a electrical diagnosis and found that the rotary swich contacts, which activates the compactor, had gone bad. I simply went to the website and selected my part # from the detailed spec sheet. I chose to receive the package on a three day shipment. Here it arrived, installed the part and away the problem went. While on the parts list I included bag brackets that had broke over time and now my compactor is like new.

Because the old coupling was so tightly screwed onto the shaft it was necessary to use very flat wire crimpers to slide between the old coupling and the blender housing to grip the shaft and immobilize it while pliers were used to grasp the old coupling and loosen it---rotate clockwise.

Part is left hand thread. Use screwdriver to lock motor fins and twist off part.

Pried the old coupling off and unscrewed the metal piece remaining then screwed the new coupling on.

simply hold the axel with the wire stripper to prevent from rotating. Using the pliers firmly turn old coupling counterclockwise until loose. Once this coupling is totally off you are ready to screw on the new one. Very simple. The most difficult part was finding a tool slim enough to fit between old coupling and base to hold axel from spinning. I ordered part on sunday and received it on tuesday. It spared me from throwing away a $120.00 dollar kitchenaide blender.

I first tried to do the repair just like the directions ,trying to force off the wheel. Then I tried doing it the way the readers here did with a tthin pliers and was not sucessfull. I then took it to a hardware store and ask about a certain pliers,they did not have it. The older man at the register took two screwdrivers from the jar next to him took my blender and pried on either side and popped off the wheel just like the original directions said. It was then easy to put the new one on.

Being an aircraft mechanic for years I pride my self on being able to fix anything that my wife buys. So I tried to replace the drive gear for her kitchen aid blender without reading the instructions, much easier to read.
Thanks,

My husband lifted off the old piece with some difficulty and then just screwed it back on. We were really glad to have our blended back as good as new for under 20$!

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?!
