KSM151 KitchenAid Mixer - Instructions

Once I looked at the schematic I was prtty sure what the problem was and what I needed to repair the problem. It was reltively easy to disassemble the mixer and immediately saw that I was correct in what was needed. I ordered the parts. They came through with no delay. It took almost as long to find all of the parts as it was to do th ... Read more e repair. In all it took about a half hour to repair, put it together and clean everything up.

Took the old feet (5) off and put new on the Kitchen Aide, looks great. Stands high and your assistance on the phone, was so appreciated.

My early '60's Kitchenaid K45 mixer screw cap/base plate would no longer hold the bowl, so I looked for another. This item, though not an exact replica of the original, fit and works great. The design is better by being more stout than the original. Pretty straightforward installation: remove three screws, take out old base plate, install ... Read more new plate and screw down.

Very messy as there is lots of heavy grease inside the mixer and you have to fish out the blown gear parts. I vary glad I took shop class in High school as it preped me for the job. The machanical drawing you provide were very useful but you should mention the grease.

Mixer works just like new. and I got the parts in two days w ... Read more ith standard shipping. Pizza on Thursday and fixed by Saturday

Took the mixer apart and cleaned the grease so off I could see the pins. Wasn't a hard fix only thing is make sure to clean the grease off so you can see what your doing

Removed old gear and grease and replaced gear and grease resembled

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 ... Read more 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.

‘Can’t remember well enough to describe accurately. Removed one screw to remove rear cover. Removed two screws to remove bright-metal band - probably not necessary but it did yield a bit more working space. IIRC, three screws and removing wires from spade-connectors was sufficient to remove the speed control plate. Remove one more screw ... Read more to remove phase control board (probably unnecessary). I took close-up pictures with my iPhone first to assure wires would get replaced on the proper lugs (only to discover the wiring diagram later). Adjusting the control plate to meet the speed criteria in the instructions was very easy. It did serve to remind me that I probably didn’t need either of the new parts; readjusting the old speed control plate would probably have done it. But I appreciate the POM brought on by the new parts.

It’s an incredible pleasure to work on something so well-made as this old Kitchen-Aid mixer. I just enjoyed handling it! Having achieved a proper repair was rather satisfying too. I just loved the entire experience!

Obviously the problem was in the gear box of the mixer. I disassembled the gear box by removing the four large screws holding the base then the four screws at the rear and center of the mixer. Then I removed the thin metal ring covering the five screws around the front of the housing by gently prying up with a small screwdriver. The fiv ... Read more e screws beneth the ring have to be removed with a small blade screwdriver turning them a round at a time in sequence until they are free. Gently pry the two housings apart with a screwdriver and lift our the lower half with the plantary gears. I found the drive gear was stripped. I went to PartSelect on the web, eaisly found the exploded view of the mixer's gear box and ordered the gear I needed. The gear is part of an assembly attached to the mixer housing with three screws. Work around the lubricant in the housing. Within four days I received the new gear, installed it by reversing the above procedures and the mixer is working again. The total cost was $34.85. Not a bad investment considering the mixer cost over $400 and would have been trashed for want of one part.

I disassembled the mixer using a YouTube video as a guide. Disassembly was easy, as everything was held together with pins and threaded fasteners, and all electrical connections were plug-on.

Cleaning out the old grease was messy and time-consuming. I used a putty knife, screwdrivers (used them like small putty knives in the ... Read more crevasses), paper towels, and finally, small cloths dampened with alcohol. After about a hour (maybe 90 minutes) everything actually looked like new.

I originally diagnosed the problem as the plastic gear loosening up from it's hub, so I ordered the complete gear tower assembly. It turned out not to be the problem- the gears were fine. With the gears removed to eliminate load, I applied power and saw that the original symptom was still there.

Further research turned up that this symptom is more likely a failed field coil, or possibly the phase control board. I ordered both from PartSelect. In the meantime, I tested the armature by measuring the resistance across the brushes as I slowly turned it by hand. At every angle, the resistance was about 7.5 ohms. Nothing lower, and no opens, so I'm pretty sure the armature is OK.

The phase control board arrived, but as of this writing, the field coil has been back ordered for almost a month. While I waited, I tried a partial reassembly of the head with the new board, and it worked! This weekend, I'll finish reassembly of the motor unit to the base/gearbox and calibrate the speed governor. In addition to the new gear tower and phase control board, it has new grease, seals, and both side levers (tilt and speed control) that had lost their knobs some time ago.

Hopefully it will be ready for another quarter century of use!
