5K5SSWH4 KitchenAid Mixer - Instructions

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

Two flat head screws removed, swapped out the latch, and replaced.
The entire repair took about two minutes.
Price was acceptable given the worth of the mixer.

I removed the pin from the outside shaft,then removed all screw around the body of the mixer,then removed the top case out,took 3 screws out from the the gear assembly case......punched the pin out of worm gear then release the little shaft out from the case,replaced a new one....then starting go backward till completely all assembled don't forget lube grease to all gears and test run good very smooth.........it's ok

Removed the two screws that hold the bowl spring in place. Removed broken spring. Replaced broken spring with replacement spring. Tightened two screws that hold it in place.

First of all I found the part in no time flat and ordered it early afternoon and it was at my door within 24 hours! My son was off work one day and I asked him if he needed a job to do and he said "sure". So I showed him the new part and where it goes and in less then 10 min it was working. awesome!

Unplugged mixer. Removed screw holding cover on. Removed end seal. Inspected repair area for furhter damage. Installed new end seal and cover.

Was able to use the diagrams to figure out how to put everything back together. Would have been a nightmare without that as I took the thing apart without really paying attention to what went where. The hardest part was inserting a set pin that holds the Bowl lift arm, which fits inside the stand. in place. So new parts - $20, less than an hour of my time disassembling/reassembling, probably saved me $125 in repair plus a couple hours driving it to service place and picking it up. No brainer.

removed old screws and latch, replaced it with the new. took just a few seconds. This is the first time i ever fixed anything. customer service was amazing

While kneading dough, my 27-yo stand mixer walked off the counter, and shortly thereafter the plastic bowl lift arm piece broke. After a quick internet search I ordered the part. Installation was extremely easy. 1) Using a rachet with a #3 Phillips head bit, remove the four screws holding the motor to the base. 2) Using the Roll Pin Punch pop out the roll pin. 3) Loosen and remove the cotter pin with the screwdriver and pliers. 4) Remove the broken piece. 5) Attach the replacement piece to the handle and insert the roll pin, tapping into place with the Roll Pin Punch. 5) Attach the lift arm to the piece and fix with the cotter pin. 6) Reattach the motor to the base. Ready for 27 more years of stand mixing duty!

The insertion part of the foot was tapered to fit in the hole in the mixer. Simple pressure was not the answer. So I used a small key, placed it on the bottom of the foot, after applying a little vegetable oil on the foot, and tapped it into place. Worked well.Joe

Used the diagram on the website and a video
Totally worked!

Fairly easy if you have done it once before.

I screwed the two screws into the place of original holes and Voila! it was repaired.

Rather than duplicate previous repair works, I recommend going to this user site and follow their instructions: http://www.neilcrockett.com/mixer1.htm. Once you have done this repair, taking the unit apart is easier to perform this tasks. Order replacement Grease "Benalene 930-2" in the 3.3 oz container and be sure to use the full container to lather all around all the gear components so grease will be available to units for years to come due to heat build up under load. Too, the 3.5 oz container is made for one unit repair job and is available through Amazon. This grease is available on larger quantities if needed / desired. I did order both, a Worm Gear and the Worm Gear and Bracket as I wasn't sure of my mechanical ability to make this repair until I got inside the unit but the worm gear is easily replaced once you clean out all the old grease. The worm gear is a neoprene type gear with all other gears being metal. I assume neoprene is used as sacrificial to save other gears from breaking under loads and years of use.
