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
