4KSB5GN4 KitchenAid Blender - Instructions

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.

it was too easy, i only used my hand to screw the coupling to the blender.

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.

The coupling split apart on my Kitchenaid Blender. I ordered the coupling part and "Bingo", I was back in business. It took no time at all and one screwdriver. I saved penty of money by not having to buy a new appliance.

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

Just like the directions said, I pryed up on the coupling at a few points around it's circumference and it became loose enough to unscrew. I didn't believe it was going to work at first but, amazingly, it did. All that was left to do was screw on the new part. No problem!

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

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.

The replacement part arrived so swiftly I didn't know what it was until I opened the packet.

The motor drive shaft has two flanges on it that can accept a narrow wrench and the drive wheel can be screwed off clockwise!
Alternatively the drive wheel can be easily prised off and the drive wheel screwed on anti-clockwise thread.
Success
Of course if the drive wheel was made of a more durable material this would not have been a problem unfortunately typically american not made to last!

Because the old coupling was so tightly screwed onto the shaft it was necessary to use very flat wire crimpers to slide between the old coupling and the blender housing to grip the shaft and immobilize it while pliers were used to grasp the old coupling and loosen it---rotate clockwise.

I used a straight edge screwdriver. At first my husband and I were afraid to much too much force behind the old coupling, but I figured it's no good the way it was so used more force and "pop" it came off. Then installed the new one and I love my blender!!

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

Simply followed the online video instructions. Screwdriver to remove the worn out part. Rag to clean threads. Hand tighten replacement part (reverse threads). Blender fully functional. Couldn't have been easier.

Went easy

Last time this happened we simply used a thin wrench to unscrew the damaged coupling. This time it was so tight no wrench could undo it. We had to grind it off using a grinder drill until it was so loose it popped off.
