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!

a special wrench should have been provided, due to the small space available under the coupling. I had to cut the existing damaged part off in order to grasp the shaft, to remove the old part.

you should provede a wrench and instructions with future sales. the average person would have returned the part for credit, and bought a new blender. i repaired it. L. Clauss, ME.

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.

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.

Followed the enclosed directions, Pried the drive coupling off the shaft with a screwdriver, cleaned the soft metal chips off the threaded shaft and screwed on the new coupler.

My husband actually did the repair and he simply followed the instruction that came along with the Coupling part ordered. Within 10 minutes, he was done with his repair. We were both happy and surprised. I thought it would be difficult for him to do it and I initially wanted to just buy a brand new blender rather than trouble ourselves with doing the repair. With the cost of $15.00 inclusive of shipping cost, the blender is working perfectly and we were able to save money. We are happy with our order and would definitely recommend others to do the same thing. In only takes a few minutes to place the order on-line, about two days for shipping, and about 10 minutes for the repair... What a relief! Thank you to part Select.com :) Deb and Don Dominguez

I was going to throw this expensive blender in the trash but decided to buy the part instead. I'm sure happy that I found this part dealer and was able to fix the blender since it was quite an expensive item. I watched the video on how to replace the coupler and I was able to replace the coupler within minutes and the only tool needed was a screwdriver. I just gently and patiently worked the old one out and basically screwed on the new one. It was very easy and a woman can easily master this repair! I did.

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.

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!
