Repairing/replacing worm-gear (FSP part# W10112253) for a KitchenAid Stand Mixer model number K5SS. First: I am writing this story because all the videos or repair articles I’ve viewed are either misleading or incorrect in that they do not include older K5SS models. 1. These older models from the mid 1960’s or even earlier have four very large #4 chrome plated Phillips Head Screws holding the mixer base to the motor assembly and NOT four small machine screws (one with a lock-washer) as seen on other repair videos. In addition, the stand is composed of two separate pieces with the bottom half being held together with another four identical #4 chrome plated Phillips Head Screws. The upper four holding the stand to the motor housing (I used a manual impact driver to loosen the very stubborn, #4 Phillips screws) must be removed so as to access the four smaller Phillips machine screws (no lock-washers found here, best buy at least four #10, split, before reassembly) 2. Lastly, you will need two pin punches however the recommended smaller 3/32 inch is still too large to remove the pin in the tower assembly. You will need one size smaller or a #4 pin punch instead. These older Kitchen Aid mixers were built with very tight tolerances. Please be patient and take your time removing the pins. Good Luck……. Jim

removed the screws holding the mixer housing and then removed the worn worm gear by removing the roll pin holding it on the shaft. Replaced the worm gear and inserted the pin that hole it in place. Replaced some of the gear grease and reassembled mixer. Went very easily. No problems at all.

The part fit great! PS. I may need to buy a gasket to go around my refrigerator door. I have an Amana Model #THI1853W, Serial No. 9502301998. Do you have instructions on how to install this gasket?

Motor would not turn on

Initially removed carbon brushes then inserted the new carbon brushes. The motor still did not turn on. Then I removed the brushes again, used a flashlight to look in the hole where the carbon brushes are installed. I noticed that there was a square notch on one side of the hole. I then reinstalled the carbon brushes, ensuring that the beveled side of the carbon brush was installed so it lines up with the square notch. This allows the carbon brushes to touch the motor. I turned the unit on and it worked.

Fast speed on every setting. No control of speeds.

I removed the cover off the back of the mixer. Carefully remove the cardboard gasket around the outside edge. Unlock the nuts that hold the two adjusting screws. Count the turns to remove each screw in order to keep the right adjustment. Pull the plate away enough to remove the control board. There is one long and one short wire that gets plugged into each side of the plate. Watch the location of each wire to make the right connection. Reattach the screws to the proper position. Then install the gasket and rear cover. Check for proper operation.

My kitchenaid stopped moving

My husband looked at youtube to figure out what the issue was. He saw a video that identified that the likely problem was the worm gear. My husband took the kitchenaid applicance apart, as he saw in the video. We ordered the part, it took less than a week to arrive. He rewatched the video that demonstrated how to put the kitchenaid mixer back together. It's a bit messy due to all the packing grease, but a pair of nitrile gloves, paper towels, and an old rag help. We put a garbage bag over the appliance after it was taken apart to protect it from any dust and my curious cat. We let the kitchenaid cycle for about a minute to make sure the gear was greased. I haven't used it to make bread yet, but I'll do that soon. Thanks for supplying the part that saved us at least one hundred dollars and TRY to get a person who will repair small appliances.

Neither motor brush popped out with the spring as shown on videos. Both appear to have disintegrated in part and had to be chiseled out delicately using and ice pick and tapping gently with a hammer. This left a carbon powder and pieces of the old brushes on the counter. Inserting the new brushes was as easy as shown on the video.

I took out the worm gear and replaced it with the new one. It is important to have the correct punches that are just under the diameter of the pins.

The screw cap no longer held the bowl in place.

This is the easiest repair ever! I removed the 3 screws, cleaned around the area with a sponge and kitchen cleaner and put on the new cap. The screws went back in easily and voila ! Done!
