KSB5ER4 KitchenAid Blender - Instructions

Turned the mixer on its side and slid the part into the bottom of the base.

I removed the bottom part of the blender and added the seal to the blade area, screwed it back on and voila! I appreciate that it was so easy.

The first thing I did--and the first thing you should do--is to read the other repair stories. There are some that recommend prying the coupling off, and some that recommend bicycle wrenches, and some that advocate the use of pliers. Use the strategy that fits the tools you have at hand; the person who actually ground down a wrench is way more dedicated and hard-core handy than I had time to be. Also, prying round things with a flathead? Surefire way to have the screwdriver slip off the drive shaft and go right through your hand. Ouch.

I didn't have a thin enough tool to grip the drive shaft just below the coupling, but I did have a flathead screwdriver narrow enough in diameter to put it through the vent and the fan blades at the bottom of the base--and long enough to fit all the way up through the blades to the motor, to prevent it from turning (6"). I had to insert and re-insert the screwdriver through the bottom a couple of times, until I got an angle that actually prevented the motor from turning (pretty close to straight in, straight up).

Motor secure, I turned the broken coupling CLOCKWISE to unscrew it (thanks for the heads up, fellow repairpeople!). The first turn need an assist from a big pair of pliers, but after that I unscrewed the old and screwed on the new coupling by hand. Easy!

Kitchenaid has a site for self repair videos. I watched the video and did what they suggested. You have to pry the drive coupler off its drive motor. It is screwed on and you can't unscrew it. So you are actually stripping the drive from the motor shaft. It seems destructive at first but just work it gently and keep the housing surface protected from the screwdriver shaft so as not to scratch it.

Continue to pry the coupler loose evenly by gradual turns and prying until it comes off. It will take about 5 minutes or so to do it firmly and evenly as you spin the shaft 30 degrees at a time.

Then you just clean off the shaft screw of any old metal shavings remaining from the old coupler and gently screw on the new one (counter clockwise)so as not to strip it.

Good as new. I love the Blender and the cool blade for making smoothies.

Happy repairs!

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.

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.

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 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

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.

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.

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!

I should have watched the video, and/or splurged and bought the little wrench to hold the motor shaft. To be clear, the video has you use a flat-head screw driver to PRY the old coupler off the threaded motor shaft - not to unscrew it. You might be able to unscrew it (particularly if you have the wrench), but my coupler would not unscrew even after I used penetrating oil. Eventually, I used a pair of vice grips to pry it off - somewhat similar to the method employed in the video. I thought I would strip the threads on the shaft, but I did not. Then I simply screwed on (counter-clockwise) the new coupler and the blender is as good as ever.

This was quite simple and easy to replace.
