KSB5-3 KitchenAid Blender - Instructions

I used a screwdriver,pulled out the piece,then change with a new one,that I was ordered before.It was ver easy to assembly.

Followed the video you sent removing the old drive coupling. Installed the new part according to instructions. I found I did not need to order the seal. I am a do it yourselfer and have never had such a good experience.

Since the coupling is threaded, it can be easily screwed on and off if you immobilize the shaft. If you don't have a tool that can do this (the space between the drive coupling and the body of the blender is only about 1/8"), you can insert a long bladed screwdriver into the vents on the bottom of the blender and into the motor. When you turn the coupling, the motor won't rotate and you can easily screw off the coupling (the threads are reversed, so turn the opposite way). Good luck!
Good

I utilized the "pound the coupling in a clockwise direction" to loosen the coupling. Two good "wackes" and it was loose. Installed new coupling. I found this method in the previous customer installation instructions on the site. Please note that my new part number is ps401661. This part works normally even though my model number did not list a part number, perhaps because my blender is an older model. Without the installation instructions site I would not have known that the thread was a "reverse thread". This site is very helpful. Good luck

popped off the old one, popped on the new one. could not have been any easier. :)

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

Just took a screwdriver and pried off the broken coupling as the instruction said with the part. Don't stress it really works and is easy. Ordered the part on Monday and recieved it on Tuesday. Great service from Partselect!

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. Good luck.

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 part.

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 bought 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.

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.

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 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

Removed the coupling as shown in the video and on the instruction sheet that came with the part. Put the new coupling in place. Noted that the coupling has left hand threads. No problems.
