KSB5WH4 KitchenAid Blender - Instructions

followed instruction, prying off old coupling and screwed new coupling on less than 5 minutes. Parts came in a timely manner. great service, satisfied customer

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

Took the coupler out with the help of screwdriver and put the new coupler. really easy fix insted of buying a new blender

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

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...

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 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.

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!)

Followed instructions that came w/ packaging. Used large screwdriver and needle-nose pliers to slowly pry old coupling off. ** Would be nice if a small flat disposible wrench the size of the shaft diameter was included. Would make things so much better and quicker!!
