3K5SS KitchenAid Mixer - Instructions

Repair went well after I figured out how to dis-assemble the mixer. Used straight & phillips screwdrivers and a small hammer & punch to drive out 3 pins. Ordered part# PS734233 pinion & shaft as shown in the parts page, it arrived on schedule, received part # 240210-2. Only problem was the new pinion had 10 teeth, the old/failed pinion had 11 teeth. Could not learn from anyone I called at PartsSelect or Whirlpool if the 10 tooth pinion was the correct part to use.
The teeth appeared to mesh with the mating gear,
installed the new pinion, reassembled and it worked fine. Not sure if it made a noticable difference in the output shaft speed.

Got a harvest gold mixer from g maw and thought a project would be nice we have several of these mixers in the family i knew a 2 prong cord was not safe so i took apart the mixer and wanted to regrease it just give a lookie to see what i needed and then i decided after watching video on y tube to convert to a solid state.

Parts select as a whole has been very understanding as a whole and i will continue to get parts thru them they are genuine parts which is something i had to have i have 90% of my parts for a full overhaul we just cannot get the parts delivered fedex and usps i specify the address and they deliver 2 blocks east of the house thanks for honest neighbors usps was late as usual like i said parts select is outstanding at placing the order and appliances can be fixed super simple with the right tools the concern is with the fedex and usps now they are shorthanded but lets be real but when you deliver a package just triple check it is the right house !

The repair guide has understandable text and good photos of how to do a thorough evaluation, disassembly, and reassembly. It is available here,

I used a clamp type amp meter and calculate watts, 120 volts times amps = watts.

INSTALLED PHASE CONTROL BOARD AND SPEED CONTROL PLATE, BOTH AT SAME TIME
Your DYI video was helpful, especially holding the spring with a cloth. Also good for fine tuning to get the speed exact

I replaced the phase control board because the mixer had only
one speed and was surging. I noticed from other posts that it
is important to note the setting of the speed plate before you
remove it in order to remove the phase control board. Also be
careful removing the associated 'slip-on' terminals as it would
be easy to damage the speed plate. If I ever do this again I
will go ahead and replace the speed plate, probably the cheapest
item to replace. The operation was a success and the mixer is
back in business. Thanks.

I watched a YouTube video all the way through, then watched each segment and followed along with the video. It was messier than the professional repair guy, but it worked out fine. This is not a difficult repair when you can watch a video and follow along. It saved me about $130.

Found control backplate out of adjustment. Should be nominal 3/8".Broken speed control spring which attaches to backplate bottom.
I recommend Loctite Blue to complement locknut's when adjusting RPM of "Stir" speed

replaced gear, and brushes.

Followed web site's videos. One step left out of video.

watched how to repair

Followed instructions found onllne at Kitchenaid.com and replaced seals with parts obtained from PartSelect.

First i went to the Kitchen Aid web site and found a video on how to take a part the mixer. Followed the instructions from the video and it was very easy. The grease in the machine was black so i cleaned it out of the transmission and repack it with hi-heat wheel bearing grease that i got from a auto parts store it took about a 1/2 lb. then put the gasket in and back together and put the o-ring on. Have run for awhile and it is ok. Want to say that these are very well built machine.

Took each area apart. Replaced the gear and reassembled it.

I am not handy, but was able to follow this YouTube video and do this repair easily and successfully: https://www.youtube.com/watch?v=1QsgPIL9FpA

I did take the mixer apart first to verify that the worm gear was the issue, then ordered the part from you site. I received it quickly and was able to do the repair and get back to mixing in a few days!

I watched the university of YouTube videos, and followed their instructions.
