5KSB52BOB4 KitchenAid Blender - Instructions

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!!

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,

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?!

Used a wrench 19/64 flat

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.

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

Simply followed the online video instructions. Screwdriver to remove the worn out part. Rag to clean threads. Hand tighten replacement part (reverse threads). Blender fully functional. Couldn't have been easier.

place screwdriver under old coupler and pried up on it in different spots until it popped off. Took less than 5 min. to do.

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

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.

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 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.

Read prior reviews from people who have done the same repair. Grasped shaft with thin nosed pliers and turned drive coupling counter clockwise.

The repair is easy. Just follow the directions that come with the replacement part. And parts select is awesome. I received the parts within a couple of days and fixed it right away.

I will definitely use this company again. The blender was over $120 when I brought it and I did not want to spend that kind of money again. My cost to fix was about $8.00 for the part and $7.00 for shipping. Hmmmm, $15 vs. $120+ sounds like a good deal to me.
Thank you.

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.
