I removed the decorative band that covers the seam by removing 1 screw. I then removed the top portion of mixer by removing 4 square head screws. You will then see the gear housing in the front of the mixer. Remove the 4 screws holding that on. There are no spring that are going to pop out and you never know where they went, but be careful because there is a lot of grease and a gear that it just laying in there on the right side. You will see the stainless shaft with a couple on gear cogs on it. Remove the retaing spring from the shaft and pull the top gear off, it may be a little snug. You will then see the dowel pin, mine was sheared off but I could see where it was. Be sure to remove the broken pieces. Use the punch to knock out the remaining pin. Replace with new pin making sure it is evenly exposed on both side of the shaft. Replace the top gear, then the retaining spring, the the gear housing cover, then the mixer top cover and finally the decorative band. Be sure to unplug before you start. These mixers are expensive and expensive to have someone fix them. I ordered 2 pins because shipping is a little high and the pin is cheap. I fixed this for $17.00 total and have a spare pin.

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.

Really no help from Kitchen Aid sources; but phone call to PartSelect solved the problem. Kitchen Aid repair line didn't even know the part #! Thanks to Part/Select, Christmas cookies are being made.

Mixer suddenly ceased operation after sharp noise

To access the interior of the mixer, I first removed the single screw holding the cup-shaped part at the rear. Then I removed the 4 large screws on the under surface of the mixer head. Next I removed the bright metal ring around the planetary gear area by prying it off. I then pried the dish-shaped part off the shaft using a large-bladed screwdriver. This exposed 5 screws on the circumference of the planetary gear. By removing them, one can pull up the gears and see into the area below. I found the worm gear had fractured. By removing 3 screws at the base I extracted it for closer inspection, checking for any loose pieces. Beware of the jelly-like grease. The replacement part goes into position, and one then follows the steps in reverse.

Very Happy

After stalling the mixer while mixing dough I found that the motor still functioned but the blade didn't move. I basically took the mixer into my shop along with a digital camera to record any complicated disassembly procedure I might have to deal with for reassembly and proceeded to disassemble the mixer. Once apart, I cleaned the mixer parts, removed the broken worm gear and bracket, and got online for someone that carried the replacement piece. PartSelect sent the replacement within 3 days and now it works great again.

No nstallation required, simply attach.
Your website was the only one that made sense. I am blind and follow the instructions with a screen reader. I had no difficulty. It was much easier than this questionaire.

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

I did not do the repair myself, however, I contacted a suggested service company which in turn was a company I had used before when I had problems with my JenAir microwave. Excellent service, prompt and very professional. Thank you JenAir for your assistance in providing promptly the parts needed to complete this job.
