Ultra Durable 9704230 Blender Drive Coupler with Spanner Kit Replacement Parts by BlueStars Easy to Install Exact Fit for KitchenAid KSB5WH KSB5 KSB3 Blenders Replaces WP9704230VP WP9704230

For the second time, I needed to replace the drive coupler on our KitchenAid blender. When I did it years ago, the only method I could find online was the screwdriver/brute force method. This time I searched Amazon and found this little kit with one coupler and a flat spanner wrench. The wrench holds the threaded spindle while the coupler is then unscrewed and replaced. IMPORTANT - the coupler is reverse threaded, so it unscrews in the opposite direction. I had trouble removing the old coupler with my hand, as it was tight and the rubber was coming off on my hand. So I retrieved a pair of channel-locks from the garage and easily removed the coupler and screwed on the new one. Took about two minutes. As everyone knows, the coupler design on these blenders is terrible. However, with this little spanner wrench, replacement of the coupler just got a lot easier. I don't know how long the coupler will last as the rubber is soft so that it will grab to the spinner blades assembly. I don't know why the part could not be made of something more durable. I'll probably order a multi-pack of the couplers to keep on hand. I don't understand the negative reviews for this product. People are saying the spanner wrench bent and was unusable. Maybe they didn't understand the part about reverse threading? Maybe they had the wrong blender?

Was ready to replace my KitchenAid blender- works great but the gear had fallen apart. Saw the price and cheap quality of new blenders and on a lark decided to see if I could buy the gear. Found this gear with the wrench for just a few dollars. In a few minutes it was working like new. Gear fit perfectly as is actually better quality than the original.

Replacing the coupler was a 2 minute job, and super easy with the supplied spanner. I also needed to replace the cutting blade dome, but once both were out the KitchenAid blender is as good as new. Operates smoothly and much more quietly than the old one.

Here are the instructions you'll need in order to use this set: 1. Fit the wrench (spanner) between the coupler and base. 2. In order to remove the existing coupler, turn the wrench counter clockwise, while turning the coupler clockwise. Depending on the condition of the coupler, you should be able to do this with your bare hands but may need to use pliers on the coupler. 3. In order to attach the new coupler, put the coupler on and turn it counter clockwise to tighten, while turning the wrench clockwise. Gave 4 stars for installation: it was easy, but only after I had to look up instructions. 4 stars for material quality: the wrench was strong enough, the coupler seems to be made well enough. 3 stars for durability--I have no idea how durable this will be. UPDATE 10/17/2023. Coupler teeth are starting to tear. Will be purchasing a new one. This last one lasted us 4 years and 8 months, with maybe the equivalent of weekly usage? Or every other week usage? Hard to say---our daughter makes smoothies regularly over the summer and then doesn't use it in the winter.

Part came with necessary tool to remove the old one. Clear directions and easy replacement. Just as described reasonably priced and blender works like new. Would recommend.

I had previously purchased the blender head sans wrench (after watching a no-wrench video on how to attach the new head by forcing it on which didn't work). After more exploration I discovered I needed this wrench. I tried to buy the wrench from my hardware store, but couldn't find the lone wrench so went ahead and purchased the set. I installed the new head quite easily and gave a whole new life to my blender.

this item has way outlasted it's OEM brother. The OEM part used to shred itself at least once a year. since I installed this item it's still works great.

Perfect replacement part for our Kitchen Aid blender. Tool worked perfect for the repair.

Easy-Peasy. Repair took 5 minutes Coupler fit perfectly and our kitchenaid blender is working again. Do watch the YouTube video on replacing the coupler. The coupler is left hand threaded (turn CLOCKWISE to loosen) It will show how to use the tool

Fonctionne tres bien

It was very easy to replace this part with the tool provided. I had my blender for 20 years before I needed this part.

These things break when you least expect them to. Have a spare on hand.

This coupling was an exact fit to replace the original on my KitchenAid blender. Easily changed using the wrench supplied with the coupling and the delivery was quick!
