KSM150PSER1 KitchenAid Mixer - Instructions

dis-assemble, replace part, re-lube, reassemble, test good.

We simply replaced the gear with the new one. It was very easy to install.

Easily took apart and replaced gears. thanks

just as the you tube instructions said.

replaced worm gear and wonderd why they used plastic instead of a stronger metal gear, unit works fine

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 !

Watch U Tube video. Take care to keep track of disassembly. Hard part was to have 4 types of screw drivers to fit the different screw heads. Be sure to clean broken gear clogs out of the grease. Parts select lady was a great help. Download Parts select diagram for extra help. Time and patience!

Watched a couple of youtube videos and it was easy.

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.

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

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 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.

Dismantled the mixer, took photos, and re-assembled unit.
