Review on 🔧 Ultra Durable W10112253 Mixer Worm Gear Replacement Part - Fits Whirlpool & KitchenAid Mixers - Pack of 2 by Stephen Burgstaller

Don't buy them as a waste of money and the seller is aware of the issue. I sent them a video of the issues and reported it in 3 separate emails. The only response was "sorry", maybe you bought the wrong gear, maybe you installed it wrong. After sending them a video about the problem. The GEAR is not attached to the aluminum hub. If you just mix lozenges and runny stuff it will work. When using the attachments or kneading bread dough, the gear slips. Looking at the design it looks like the gear is being pressed/restricted onto the hub rather than injecting the gear onto the hub. My solution to the problem would be to attach the gears with two stainless steel pins. If you're not willing to take that extra step, run away.
