Now you will have to drive the drift pin out that holds the worm gear in place, slide the shaft out then remove gear. reverse order to assemble

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 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 with 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

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 five 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 called my fiancée.

Turned the mixer on its side and slid the part into the bottom of the base.

Three phillips-head screws held the "Cap Screw" in place on the stand of the mixer. After cleaning the stuff out of the screw slots, the screws came out surprisingly easy. After the plate was lifted off, we cleaned the residue from under the plate, placed the new one in position and easily screwed in the 3 screws.
We were very pleased by the quick delivery of the part.

Took out 3 screws, removed old plate, put down new plate the tightened screws. Runs like new, great service, price, quick delivery!

Inserted new pin and tightened set screw.

Followed step-by-step video instructions for dis-assembly/reassembly found at ereplacementparts.com. All went well except when driving out the pin that holds the worm gear in the tower. The video wasn't exactly clear enough about what position the pin should be in when driving it out and I inadvertently drove the pin out so that it was trapped inside the tower assembly. Result? I had to bend the pin to get it out, causing an extra expenditure and wait time to order a new pin. So, lesson learned: be sure the pin is horizontal to the tower and not perpendicular to when driving the pin out. Also, I found that having the mixer apart was a good time to replace the grease in the housing. I don't think it would be required to replace the grease at this time but I was worried that pieces of the old worm gear could remain in the grease and possible get jammed in the gears after repairs were completed. Be sure to get a "food grade" grease not grease from your local auto parts store! The table knife was the best tool to use to remove the grease and to smear the grease all over the internal gears when replacing it.

removed the screws holding the mixer housing and then removed the worn worm gear by removing the roll pin holding it on the shaft. Replaced the worm gear and inserted the pin that hole it in place. Replaced some of the gear grease and reassembled mixer. Went very easily. No problems at all.

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

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.

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.
