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

and I thought replacing the hinge pin would fix it, I used an awl to push out the old pin then used the new pin to push the old one all the way out. That did not fix the problem. Went to a store to look over a new one and saw that the screw under the head at the hinge point on the new machines was not screwed in tight. Turns out that screw is the "bumper" for the head against the neck, so the head is held back by the screw. FIXED

Repair was easy. Remove the seal ring with a flat blade screwdriver and drive out retaining pin. Pry out lower unit using two screwdrivers, one on each side. Once apart, use spring clip pliers to remove snap ring. Pull out shaft and replace. Clean and lubricate as you reassemble in reverse. Google the model number to get detailed instructions.

worn teflon worm gear

  • Customer: Frank from Bethlehem, PA
  • Difficulty: Really Easy

it was a kitchen aid dough mixer, had to take the top portion off and replace the assembly with a new one that holds the teflon gear. You can purchace the gear only and it becomes less expensive, but at the time I didn't take the chance cause the greese was there and didn't want to take a chance. Its a simple repair by removing some cotter pins and phillips head screws.

The brushes on the inside of the motor were destroyed. We thought that it would be easier to just replace the brush holder and the brushes, however, the brushes were easy! and QUICK! The brush holders...not so much. We had lots of problems getting the brush holders into place because of a metal piece that had to fit perfectly on top of the brush holder. It made it easier when I held the mixer upside down (we dissembled it) and my husband did his magic on fixing the brush holders. Pray that you won't need to replace the brush holders because it was NO FUN...but the brushes were QUICK AND EASY :)

I was very happy with the customer services department and the support I received in identifying the part I needed for the repair. I received an email confirming my order with all details. I do wish you had a more cost effective shipping alternative, like Priority mail.
The repair went well and the mixer is back in business, for making those Chocolate Chip Cookie and brownies if you know what I mean.

Thank you
Ron Ashby
