5KSB52BNK5 KitchenAid Blender - Instructions

A 5/16" thin wrench fits the shaft beneath the coupling. The shaft has a flat side on it. The coupling comes of easily turning clock-wise for the reverse threads..

Per directions, I pried the drive off the screw. I was surprised that the drive came off the screw by just a prying action, but that's how it's done. The metal base to the drive is softer than the screw so there was no stripping of the screw threads. Then I just threaded the new drive onto the screw and done.

The longest time spent was in getting the part out of the package and reading the directions. All told it took less than 5 minutes.

The rubber part of the drive appears to be very brittle as it chipped off the drive gears. But it was easy to repair and they do last about 5 years.

When I googled the part I got a video of someone replacing it. It looked so easy I order the part and followed the instructions. Amazingly easy.Thank you.

I tried turning defective coupler off after inserting a narrow screw driver into the motor fan bladed. That did not work. I then used a wide bladed flat-head screw driver to pry the defective coupler disc off the motor shaft. After prying each side over and over, the old coupler base broke free. I cleaned the remnants of the base from the threaded shaft and then screwed the new coupler on only finger tight. It went on easily. For less than $15.00 (including shipping) we now have a working blender that hopefully will last another 10 years.

As per instructions provided plus other internet advice, we used a large (10 in) flat blade screw driver to pry and remove the existing damaged coupling. There was a small amount of aluminum thread residue left from the old coupling on the motor shaft. We removed this debris, 'lefty tighty'd' the new one and we were blending again! Really simple. We thought about making a 7MM wrench, then we went to our bicycle repair tools, but we the smallest Shimano we had was 10MM. All is well, we have used the blender 3 times with ice and thick stuff with no problems.

pry rubber up enough for vice grips, unscrew coupling,left hand threads,screw on new. Came with instructions, in English.

I followed the included instructions.

Removal of the old coupling was easily done by gently prying it up. The threads on ot are much softer that the shaft.

Screwed the new coupling on and done.

I also bought two of these couplings as the rubber on it WILL break off again.

I watched the video on the website and I realized I could repair a $100.00 blender myself, for under $20.00! So, so easy and the part came in two days. Great company, Thanks!

To start with the coupling, I followed the directions by using a flat screwdriver and a thick towel. I placed the towel under the screwdriver to protect the base unit from damage as I pivoted 1/2 of the tip under the coupling, pulling it up as I went around until the coupling popped off. Then I cleaned the remainder of any metal left behind. Then I attempted to screw the coupling on clockwise but the screw opening was slightly to small. So I plugged in the unit and held the coupling with the screwdriver in place and turn the unit on stir and it screwed it on clockwise.
Next, the seal was replaced at the bottom of the jar. And I was finished. Easy as pie.

The replacement part arrived so swiftly I didn't know what it was until I opened the packet.

The motor drive shaft has two flanges on it that can accept a narrow wrench and the drive wheel can be screwed off clockwise!
Alternatively the drive wheel can be easily prised off and the drive wheel screwed on anti-clockwise thread.
Success
Of course if the drive wheel was made of a more durable material this would not have been a problem unfortunately typically american not made to last!

Used a wrench 19/64 flat

Just like the directions said, I pryed up on the coupling at a few points around it's circumference and it became loose enough to unscrew. I didn't believe it was going to work at first but, amazingly, it did. All that was left to do was screw on the new part. No problem!

Forget about the repair blogs. The coupling includes a repair instruction sheet. It actually took longer to read the sheet than it did to do the repair. Follow the repair sheet instructions. Very easy, however not intuitive.

After I discovered that it needed to be screwed on turning to the left it was simple.

Intructions were simple. Pried off the old coupling with the screwdriver and applied presser to replace the new one on the spindle.

Comment: KitchenAid appliances are made to last unlike most other small kitchen appliances. They are made of strong materials and repairable where as other similar products get thrown out when they break.
