9KSM180QHSD0 Whirlpool Mixer - Instructions

Punched out the roll pin to remove eccentric from spindle, undid 5 screws (after removing trim ring), and removed 4 screws to undo the motor housing. Make sure to keep the one screw with a lock washer in the BACK of the housing. Undid the screw on top to remove the back of the motor housing to take out the strain relief grommet, prior to removing the motor housing. Scraped the excess grease into a tub to re-use. Pulled out the shaft, and lifted out the old (stripped) gear and plopped the new one in. Make sure to mark match points for parts, and put the pins back in in the right order. You have to put the 5 screws back in before sliding the trim ring on, and putting the roll pin back. make sure all gears mesh and test before snugging the motor housing screws. Be sure to orient the strain relief grommet securely, and be careful of the filter plates in the back of the housing (they're brittle). putting the grease back is like frosting a cake. Save a little for the planetary ass'y.

Literally the whole top of this stand mixer had to be taken apart. With the help of U-tube! We realized the silver strip was removable and there where screws underneath. We figured we would replace both parts while it was all taken apart. We cleaned the mixer and added some grease where necessary. I now have a 25 year old new mixer. Thanks for having our parts and guiding us with a diagram of the unit. Very helpful.

Looked for the probable cause from a U-tube video, then found the parts list and repair video on the PartSelect website. When the parts arrived within 3days the shipped email had a video on exactly how to complete the repair. Repair video was very well done and easy to follow.

Looked at the mixer schematic form your website,which made it easy for me to take it apart. Once it was apart & all the grease removed I disassembled & cleaned all the drive parts. Saw what was warn, ordered the parts from you. Three days later received the parts, everything fit perfect. Added grease,assembled the mixer and it ran perfect, good for another 20 yrs. Thank you for making it so easy to repair an old mixer in just over two hours. Rolf

Pulled off end cover. Used the how-to video's to show me how to remove the (3) components (watch out when it comes to removing the spring). Removed all (3) components (one issue was the black cardboard seal, which because of its age broke. Hindsight tells me that I should have purchased a replacement seal along with the (3) new parts.
Fixed the broken part of the seal with scotch tape). Installed all new parts with the help of the video's and put the cover back on. Even with the new parts, the mixer would not run. Come to find out, after I took it to an appliance repair person, that someone had pulled both brushes and put them back in improperly. I could not find a how-to video that showed me how to de-install/re-install the brushes properly. I assume that was because new brushes were no longer available for purchase. At any rate, when the brushes were put in properly, everything worked. The repair person also adjusted the (2) screws on the speed control plate so that when you change the speeds via the lever, it all works properly. I didn't find a how-to video covering those adjustments either.

remove the back cover part # 36, remove the top cover part # 1 (by removing the chrome ring parate # 28, the mobile disk part # 25 and six screws part # 24). This done, remove the system parat # 38 to release the Pevel Pinion Center Gear part # 15 and remove the damaged part and put the new part. The install the removed parts in reverse order as they withdrew.

Place Pin in hole where it was missing then gently tap pin into place
Run a test and all is good ??
make sure to use a drift pin set

We disassembled it with the help of a YouTube video from partselect.
We saw the damaged gear, removed the 4 screws to remove it, cleaned all the old grease out with rags so it wouldn't be contaminated by metal shavings.
We reassembled it per the YouTube video and it works better than ever!!
Make sure you remove the roll pin before trying to pry off the planetary plate, because I watched a different video first, which didnt tell me that and i bent it a bit.

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

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

Fairly easy if you have done it once before.

I just thought there had to be a way to replace a component to correct the speed problem. I've never worked on a mixer before, so I thought it would be a challenge. Actually the repair was fairly easy. Make sure the unit is unplugged from AC. I removed the back motor cover with one screw and removed the end seal. I compared the parts on the mixer with the diagram provided at the Part Select website. I then ordered the parts. When the parts arrived 3 days later, I removed the Speed Control Plate ( 3 screws) and Phase Control Bd (1 screw) as one Assy. Removed the old Governor and slipped on the new one. Assy the new Speed Control Plate and Phase Control Bd comparing wiring and screwed them back to the unit. Removed the two motor bushes by unscrewing the side black motor brush holders and inserting the new brushes. I tried powering motor and nothing happened. I thought, great, now what did I do? I found out that you must make sure the brushes actually touch the armature otherwise the motor doesn't run. The gears are worn from grinding to much deer meat and my wife says no more. I've ordered new gears and looks like that job, too, will be easy to repair. Adding these parts is alot cheaper than buying a new unit and it will run like new. Not bad for over 10 years of usage.

i disassembled the mixer until i could remove the worm gear; is in a housing that that includes another gear and shaft. make sure you have a magnetic tray to put parts in as you work or you will spend more time looking for parts than reassembling the mixer. once you have the gear housing out you will need a small diameter punch to drive out the pin that holds the gears in the housing(i used a 5/32 transfer punch.) make sure you punch the pin out where it will be caught or you will need to order that part because you will not find it. after knocking the pin out it is just a matter of removing the old gear, putting the new one in, and reversing the steps and getting everything reassembled.

I did some research and evaluated a modern day Kitchen Aid Mixer. Looked a the wire diagram and found out what items I needed. Ordered them from Partselect. Overall Mixer is updated and running. I made up some cookie dough with it. The Project took a few evenings due to rewiring the coils on the motor/armature and modifying the rear bearing bracket to hold the Phase control board (not OEM on 70's mixers). Then put it back together and adjusted the speed control.

I followed the instructional video linked to my email order confirmation. Partselect provided one of the best how-to videos I've ever seen. With the right tools, a little patience and the video, I had an outstanding repair experience.
