KSB5WH4 KitchenAid Blender - Instructions

Removed reverse thread coupler, jammed screw driver into fan blade at bottom of mixer, installed new coupler. REMEMBER, REVERSE THREAD!

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. :)

Hammer was used to remove the old one, tapping quickly on old coupling. I did use a thin pliers (wire stripper) to hold shaft when I screwed on new coupling, even though it said one did not need to. Good instruction sheet came with the new coupling.

used needle nose pliers to hold shaft after prying rubber top off. unscrewed metal tap, counterclock wise. installed new piece

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.

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.

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.

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!

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

The bottom of the coupling is threaded so that if you turn it clockwise, it just unscrews. I unscrewed the damaged coupler and screwed the new on back on.

Simply held the shaft, unscrewed the old coupling (left hand threads) and installed the new one. Takes about 2 minutes.

I carefully inserted a long screw driver into the cooling slots on the bottom of the blender to lock the motor. Then, with my hand, I turned the broken coupling CLOCKWISE to loosen. The reality is, the repair took 15 seconds

simple instructions made it easy in 1-2 minutes just by prying the part with a screwdriver. Cleaned up metal threads that fell off and screwed on new part without tightening it down. Machine self tightens. Done!!

The shaft and the coupler are threaded. On could unthread the coupler. But many time it is frozen. The coupler is manufactured out of soft metal center and plastic. If frozen, it can be pried off the shaft using a large screw driver --- per the instructions provided with the part. This worked well with no damage to the blender power shaft. The new coupler was simply screwed on to the shaft and it works fine. The online schematics provided by PartsSelect helped me identify th part, part number and the nomenclature. The part arrive on the west coas in about four day --- very quick service. Thanks, PartSelect. Great job!!!
