4KSB5SSOB KitchenAid Blender - Instructions

Popped off old drive with a screw driver. About 30 seconds after receiving it from FedEx I screwed it on and it was ready to go!

I followed the instructions as provided and as seen on your video. If I had not seen your video repair clip I would have had the blender all apart. Thanks. I saved an expensive appliance.

This is my favorite blender and I wasn't willing to buy a new one without trying to repair it. I have replaced other components of the motor but the grooves finally wore out and needed replacement so that the blades would rotate. I really didn't need the dome assembly but thought the new blades would be sharper so, might as well change it too. A flat head screwdriver was recommended for removal of the drive coupling. I found that it was digging grooves into the metal ring in the base - which would not have damaged the operation - so I took an old pair of (very dull) steel calipers, covered the ends and it popped right off. I had it up and running in less than five minutes.

This was quite simple and easy to replace.

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..

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.

followed on line instructions. Real easy to do. Now I have my blender back.

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.

Just follow directions included with part, very simple and understandable. GOOD BUSINESS, THANK YOU

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.

Use the purpose made wrench to hold the drive shaft while unscrewing the broken coupler from the drive shaft. The shaft has a left hand thread, so turn the coupler clockwise to remove it from the drive shaft. Then screw the new coupler onto the drive shaft, turning it counter-clockwise. That's it!

Exactly as described in installation instructions included with new coupling. Great feeling hearing the sound of the motor and fruit being chopped. Mission accomplished!

used 2oz. gasket hammer tapped drive coupler clockwise and ,
R&R coupler.

The instructions provided an easy repair. I just followed the recommended procedure and the repiar was a snap. Thanks for the quick delivery too, I really appreaciated that.
