4KSB5 KitchenAid Blender - Instructions

I unscrewed the old coupling and screwed on the new coupling from Partselect.
This was a personal repair job.
However, I am a local Handyman in Northern NJ that does a ton of minor repairs. For all of my appliance part needs I will buy from Partselect.com. They under promised and over delivered! Just incase you dont know what I mean by that statement,,, I ordered the blender part, they told me I would have it in 6-10 days (which was acceptable to me) and I had it in two days... AWESOME job FOLKS!!!!!!!

After reading repair stories on this site, I used wire splicers that just fit between the coupling and housing to hold the shaft while I used pliers to remove the broken coupling. I then hand tightened the new one . It works fine now.

i used the screwdriver method prying up on side to side old one comes off new one goes on pretty cool also it was a nice long flat head with pretty big head

Piece of cake. Part was expensive and shipping likewise. Very fast

with a flat wrench grab the shaft and unscrew the coupling (note: left handed threads)... then install the replacement part.

Intructions were simple. Pried off the old coupling with the screwdriver and applied presser to replace the new one on the spindle.

Comment: KitchenAid appliances are made to last unlike most other small kitchen appliances. They are made of strong materials and repairable where as other similar products get thrown out when they break.

Hardest part was taking off the old coupling. I locked the drive with a thin wrench and pryed the coupling off. Took about ten minutes to get off and two minutes to put the new gear on. Remember the thread is counter clockwise. PartSelect was great the part arrived in two days.

using the screw driver I pryed up on the old coupling as out line in the instructions that came with the part. The old part cam off easily and the new one just screwed on. The replacement took only a few minutes.

It was harder than the directions said to get the old drive coupling off, but once the old was taken off, it was a piece of cake to put the new one on.

Thanks, great service from this website, received my part the next day after I ordered it!

Using the precise instructions provided by parts select, I used a big screw driver and pried off the old coupler and cleaned the area and screwed on the new coupler. Fixed!

The part finally arrived 3 weeks later, after being out of stock and back ordered a couple times.

I couldn't unscrew the old coupling (left hand thread) so I carefully sawed a piece off being careful (the somewhat difficult part of the job) not to damage the threads on the drive motor. Then I used pliers to remove the rest of the drive coupling. Then it's just a matter of screwing on the new coupling. Good as new and I didn't have to buy a new $150 blender.

Followed the instructions that came with the replacement drive coupler, first removeing the old part using a screw driver, and then easily screwed on the new part. Removing the old part without the aid of the instructions would have been problematic.

I repaired it as per instructions provided by using a flat head screwdriver to pry the original off.

simply hold the axel with the wire stripper to prevent from rotating. Using the pliers firmly turn old coupling counterclockwise until loose. Once this coupling is totally off you are ready to screw on the new one. Very simple. The most difficult part was finding a tool slim enough to fit between old coupling and base to hold axel from spinning. I ordered part on sunday and received it on tuesday. It spared me from throwing away a $120.00 dollar kitchenaide blender.

I inserted a metal rod in the bottom of the base while I held it sideways to keep the motor from turning and I used pliers to twist the coupling off counterclockwise.
I thought at first I was doing it wrong because it wouldn't nudge so I left it alone. I then read the repair stories again and went back to it and it right came off. I guess there was a lot of gunk holding it tight.
Of course when the new one came days later it was easy to twist it on. Thank you for all of your stories. They were very informative and encouraging. Without them I'm not sure if I would have attempted it myself.
