5K45SS KitchenAid Mixer - Instructions

We have the classic Hobart-made KitchenAid mixer from the mid-1980s. The original cord sheathing was disintegrating. The replacement cord is actually a better design, but the housing needs to be filed down to slide the cord into place. The old housing channel on my mixer only allowed for something basically the cord width to fit through. The part of the cord that now fits tight against the housing is much thicker and sturdier than the original. I started with a metal file to widen the housing channel, which was working but taking a long time. My son the electrical engineer suggested a Dremel, which was indeed faster on the thick aluminum housing. We used a small circular sanding tip to avoid damaging any adjacent workings. My son also saw that the slim strain relief collar at the top of the cord was pushing and bending the wires too much against the rest of the unit, so he took an X-acto knife and gently rolled the cutting edge along the base of the top collar until he could tear away that extra collar and let the wires lie more naturally in the space. We also managed to break the paper gasket meant to shield the motor from vented flour (in my case lots of years of cocoa powder! Time to vacuum here), but taped that back together with black electrical tape. After the adjustments were made, the cord replacement itself took about 2 minutes. If your mixer is more modern, you may not need to make any adjustments like we did. Just take a picture of how the wires attach and duplicate that with the new wires in the cord.

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.

Replace went good used the online video, my husband doesn't usually use any help but said the video helped him. Now my mixer works perfect. Also the price and shipping time was awesome.

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

Got the right parts, very quick delivery, will use again.

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

I removed the spring loaded brush screw on the side of my mixer and lost it the next day. I found a schematic of this part on your website and ordered the four pieces that make up the brush screw(?). They arrived in just a few days and I referred back to the schematic to put it together. I then popped it in my mixer, screwed it down, plugged her in and away we go! Easiest repair I’ve ever done! I’m a 70 year old retired lady and not very handy, but this was an easy fix! Thank you, PartSelect!

Skewer the screw in with my fingers,

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.

Replaced the speed control plate and phase control board and works well. Pay attention to speed control board spring and adjustment lever when reassembling.

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.

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.

Watched a YouTube video to disassemble,from there went smoothly. One small piece of advice,take pictures with your smart phone during the process. Makes remembering easier.

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.
