KSB5SSOB4 KitchenAid Blender - Instructions

As per instructions provided plus other internet advice, we used a large (10 in) flat blade screw driver to pry and remove the existing damaged coupling. There was a small amount of aluminum thread residue left from the old coupling on the motor shaft. We removed this debris, 'lefty tighty'd' the new one and we were blending again! Really simple. We thought about making a 7MM wrench, then we went to our bicycle repair tools, but we the smallest Shimano we had was 10MM. All is well, we have used the blender 3 times with ice and thick stuff with no problems.

Exactly as described in installation instructions included with new coupling. Great feeling hearing the sound of the motor and fruit being chopped. Mission accomplished!

Use the purpose made wrench to hold the drive shaft while unscrewing the broken coupler from the drive shaft. The shaft has a left hand thread, so turn the coupler clockwise to remove it from the drive shaft. Then screw the new coupler onto the drive shaft, turning it counter-clockwise. That's it!

To start with the coupling, I followed the directions by using a flat screwdriver and a thick towel. I placed the towel under the screwdriver to protect the base unit from damage as I pivoted 1/2 of the tip under the coupling, pulling it up as I went around until the coupling popped off. Then I cleaned the remainder of any metal left behind. Then I attempted to screw the coupling on clockwise but the screw opening was slightly to small. So I plugged in the unit and held the coupling with the screwdriver in place and turn the unit on stir and it screwed it on clockwise.
Next, the seal was replaced at the bottom of the jar. And I was finished. Easy as pie.

pry rubber up enough for vice grips, unscrew coupling,left hand threads,screw on new. Came with instructions, in English.

I followed the included instructions.

Removal of the old coupling was easily done by gently prying it up. The threads on ot are much softer that the shaft.

Screwed the new coupling on and done.

I also bought two of these couplings as the rubber on it WILL break off again.

I watched the video on the website and I realized I could repair a $100.00 blender myself, for under $20.00! So, so easy and the part came in two days. Great company, Thanks!

None needed.

simple clear instructions to follow

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!

It was very easy to unscrew the coupler I used locktight to put on the new part. Thank you sending
the right part the first time

Released cup drive with screw driver and un-screwed, screwed on new driver.
That is all, works like a new blender.

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

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.

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!
