4KSB5WW4 KitchenAid Blender - Instructions

Unscrewed the bottom and screw it into the new glass jar.

I wasn't expecting a package when the part arrived LESS THAN TWO DAYS AFTER I ORDERED IT! I had my own idea about how I was going to replace the old coupler, which involved rigging a clamp to hold the shaft etc.

I read the instructions that came with the part and couldn't believe how simple it was. The female threads on the c ... Read more oupler are aluminum (soft) and the threads on the driveshaft are steel(hard) so it can be simply pried off with a screwdriver. I love it when brute force is the right way to fix something. The new coupling screwed on with a left hand thread, no problem. I was somewhat disappointed that I didn't get to the day tinkering, but for the price of a movie I got a new blender.

Part Select exceeded my expectations.

With a flat bladed screwdriver I pried off the existing rubber of the old drive coupling. The old coupling was dry and hard and I believe this is the reason it broke. Left on the drive shaft is an aluminum piece with reverse threads. It is impossible to remove this without a very flat wrench (which I didn't have). I took my screwdriver an ... Read more d carefully pried upward from the underside of the aluminum piece, turning the piece as I went, and prying in each side. It seems scary to do this, but the drive shaft is quite strong and I was careful not to damage the edge of the blender. After doing this 8-10 times and gradually deforming the edge of the aluminum piece (bending up a few millimeters each time) the piece turned freely. I was able to unscrew (remember reverse threads) and put the new drive coupling on. Very easy fix and glad I didn't run out and buy a set of flat wrenches.

The directions discribing how to remove the drive coupler i thought implied that you needed to unscrew the coupler. The first part of the directions discribed the the coupler was threaded counter clockwise and needed to turn clockwise to remove te coupler. The step by step directions discribed how to use the screw driver to lift the cou ... Read more pler then turn 1/4 turn then use the screw driver again. After a few tie trying to turn the coupler by hand and with a pair of pliers I realized that the couple was made out of a soft metal and was actually bending away from the drive shaft. once that was accomplished the rest of the directions made sense.

First I lifted the container off the base, stuck a screw driver up through the bottom of the base to hold engage the motor blades so I could, by turning counterclockwise, disingage the broken coupling, Much easyer than prying it off as directed by the instruction sheet that came with the part. Very simple operation and saved me the cost o ... Read more f a new food processor. Thank you

I was not sure how this peice was attached to the shaft or if even replaceable like some cheap kitchen gadgets. I checked online with parts select and sure enough as always it was, and even had some tips on how to replace from other
customers.
A 1/4" wrench that I have lots of ground kind of thin that is now in the bag with an ... Read more extra coupling for future repairs did the trick.
Grinding the wrench to fit between the coupling and motor took most of the replacement time.
The next time the blender needs a new coupling it will be done right in the kitchen.
Partselect has been super for past and present finds for replacement parts.

We:
tipped the mixer over on its side
pulled the old feet off
put the new feet in place and pounded them w/our fists
set it back up on its new feet

I used a flat screw driver and gently and forcibly removed the part as recommended in the instructional manual. Putting the replacement part was not at all difficult. With the new part in place the blender now works like new.

replaced the whole collar...very easy to repair.

All I had to do was replace the part! Service was excellent! Ordered the part and had it the next day and my blender was up and running!!

Took the old feet (5) off and put new on the Kitchen Aide, looks great. Stands high and your assistance on the phone, was so appreciated.

Did not have an open end wrench thin enough to engage the coupling shaft, so I inserted a flat screwdriver through the vent holes at the bottom of the blender to keep the motor from turning and simply unscrewed the coupling (reverse thread) from the shaft. FYI, the instructions that came with the new coupling were useless. Makes no sense ... Read more to "pry" the old coupling off with a screwdriver, in effect destroying it, when all you need to do is what I describe above. By the way - it would be really great if you provided a thin cheap open end wrench with the new coupling. Probably only add a few pennies to the cost.

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 ... Read more 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.

I got the parts in about 2 days and took me about 10 minutes to repair the blender.Best of all the parts were delivered faster then I expected.Thanks again.Greg
