5KSB52BBU5 KitchenAid Blender - Instructions

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 coupler 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 and 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 coupler 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.

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 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.

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 of a new food processor. Thank you

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.

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 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 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

Replaced collar

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.

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

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!
