5KSB52SER4 KitchenAid Blender - Instructions

Very easy. Enclosed instructions were excellent! Part arrived early than anticipated, also.

Remove blender jar to get to drive cog. Use a 1/4 to 3/8 flat open-end wrench to hold cog shaft then turn the cog with your hand CLOCKWISE to loosen. Screw new cog gear on COUNTERCLOCKWISE hand tight. Reassemble your blender and you're good to go. It takes a very thin flat wrench but even if you have to buy a set the're not very expensive ...

A very flat wrench or needle nose pliers was needed. I could not get the nut unscrewed with what I had so I had to mail the unit to a service center for repair. They were able to use the part I had purchased but if I had known I wouldn't be able to do it I could have saved a little money in the shipping I had to pay when I ordered the p ... Read more art.

Thanks to the good advise of those who did this before me ,I know I need a very slender wrench to get between the screwed on base of the coupling and the copy of the base of the blender.
I tried to file one myself, but the metal was too weak. Because i had the size (from what I filed), I measured and knew i needed a 7 MM wrench. I bo ... Read more ught one at the parts store and ground it thin enough to slip into the small space and from there it was a five minute job.

Instructions indicated turning the coupler and gently lifting it with a screwdriver. However, in attempting to do that several minutes without success had to use the screwdriver to pry the old coupler off and in doing so the rubber section separated from the metal. It was removed with pliers. Once off installing the new coupler was acc ... Read more omplished quickly.

It was more difficult than described in the directions. They said to pop off the drive coupling with a straight edge screwdriver. It took me quite a while and a lot of strength to finally get it off. I thought I was going to break it completely. BUT, it did come off and I saved myself a lot of money by doing it myself.

Read provided instructions but unfortunately looked at part and re-interpeted the instructions....Should have just followed instructions as printed. I tried to pry up and unscrew instead f just prying off...

Followed instruction sheet, but as it stated just remove by hand, not so, had to grind open end wrench to fit between coupler and base to fit flat sides of shaft, then use channel locks to break lose and to unscrew most of the way off.
But in the end the part worked just fine.

Directions included with replacement part were no help...maybe I'm stupid, but prying up on a threaded metal part didn't help unthread it at all.
Vise grips solved the problem. I used vise grips to remove the rubber from the coupler while it was still attached to the blender base, exposing the metal base to the coupler. (yes, I used ... Read more vise grips to destroy the damaged coupler. after all the hell I went through to try to do it as the directions said, it was very satisfying.)
After removing the rubber, I used the vise grips to bend and distort the metal base until I could get a pair of needle-nose pliers around the drive shaft and hold it still while I unscrewed the now bent-up metal base. Victory!
I thoroughly recommend this method to anyone else, as using vise grips to destroy something is very gratifying.

Tried to follow the included instructions - no way that just prying the coupler off would work without bending the shaft and wrecking the threads! Then used a flat, open-ended 7mm wrench to hold the shaft and pliers to remove the coupling. The coupler was so tight that I could not unscrew it without the wrench slipping. Ended up shoving a ... Read more screwdriver through the fanblade from the bottom (unplug it first!) and use the pliers to unscrew the coupler (remember, it's a left handed thread!)

it need a special tool...to remove the broken coupleing..had to have my brother-in-law who fixes industrial equipment, remove it with a special tool, that a home owner would not have

The most challenging portion of the repair was the removal of the old coupling. I ended up using a punch and a hammer. Tapped clockwise several times. It took about 20 times. Once the old coupling is removed the installation of the new was super-easy. Just screwed it counter clock wise by hand and was ready to go.

I used a screwdriver as the printed instructions said. After prying it off (took a bit of prying) with a screwdriver, I discovered the thing screws backwards. It would have been easier for me to use needle-nosed plyers to hold the shaft and turn the coupler by hand. Oh well. Works fine anyway.

Using information from other users, I pried/ripped the rubber portion off the drive coupler, leaving the aluminum disc base exposed. I did not have a thin flat wrench of the right size to hold the drive shaft, so I wound up carefully inserting the wrench into the motor to keep it from turning while I loosened the disc with pliers. Once ... Read more loosened, it was easily unscrewed, and the new coupling screwed on.

Repair parts instructions said to pry around in four places with screw driver between motors base and underside of drive gear and it should pop right off. Well it didn't and I had to go around many times being care full not to damage finish of appliance. Finally it came off leaving thread remains on the tapered threaded motor shaft. Using ... Read more a scriber, I dug out and removed all thread remains and then easily screwed on the new replacement completing the job. The blender, a good one, now works fine again.
