How to Troubleshoot & Replace Whirlpool AP6007401 / WP240309-2 Worm Gear And Bracket Assembly

Just swapped it out 

I googled make and model number to locate possible resources. I had previously downloaded the mixer manual. Entered the model and part information into your website and made the purchase. Part came in a few days. Pretty simple install. KitchenAid documentation excellent. Appliance Parts Pros makes good use of that. 

I disassembled the motor head of the mixer (according to YouTube video instructions) without a hitch. Then I inspected the different gear parts of the drive train and found the one that was damaged. Just for "insurance", I replaced the entire worm gear and bracket assembly, but could've probably just gotten away with the worm gear replacement. Put it all back together according to instructions and VOILA, it works! BTW, I waited less than 24 hours for the replacement part to be delivered to my home. 

Fast simple fix. Took about 20 Minutes. Worked great. 

Ordered Worm Gear and Bracket Assembly. 

Our local makerspace hosts a repair event once a month where community members can bring in *anything* broken. We'll fix it free but accept donations. This month a woman brought in a KSM5 mixer. The motor ran but nothing moved. It was the worm gear. These mixers can be hard to disassemble but I had done several before. The reassembly happens next month. 

Replaced gear assembly and gasket. 

Replaced the worn WORM GEAR ASSEMBLY. Very easy to do with the help of AppliancePartsPros Repair Videos. 

Replaced worm gear assembly. 

Went online and looked for similar problems and quickly discovered it was probably the worm gear. Then looked for a company that sold the part. I didn't fix it, my husband did, and the worm gear was the problem. The part came fast. This mixer is about 25 years old, and he said it took the longest time to get it apart than to fix it. It looked a mess, so he cleaned it and put it back together. Runs well. Worth the price considering a new mixer is $300.00 He used 2 flat screwdrivers, a philips screw driver, a soft hammer, a ballpeen hammer, a drill used as a punch (a mcgyver)
