5KSM180LEALB5 KitchenAid Mixer - Instructions

My girlfriends' stand mixer failed when the accessory drive cap fell into the mixing bowl and jambed the beater, spliting the worm gear. The teeth on this gear are made of nylon and are molded to an aluminum center. This part is designed to fail in situations like this, saving the more expensive transmission parts. Following a repair manual I found online, I first removed the rear cover and pulled out the cord strain relief out from the base. Next I removed the drip cup from around the base of the planetary drive. I then used a pin punch to drive out the pin holding the planetary to the center shaft and removed the planetary. The unit was then inverted and I removed 4 screws holding the bottom cover to the gear case, and the 5 screws from around the planetary drive. The bottom cover was then lifted off. Three screws holding the worm gear bracket in place were then removed and the worm gear assembly lifted out. A small pin holds the worm gear to the shaft. I drove this out with a small pin punch and the shaft and worm gear were then removed. There is also a thrust washer on this shaft, and it's location is important. Make a note for re-assembly. The new gear was installed and the entire process reversed for re-assembly. A successful repair completed! My girlfriend would have replaced this $200 appliance, but I was able to repair it for less than $30 including shipping.

I removed the rear cap, decorative strap, and decorative ring. Next I drove out the pin holding the mixing head. I then removed the 9 screws holding on the motor/gearing portion. This facilitated removal of the gearing from the motor assembly. I next laid in the new gears and calculated what thickness of fiber washers were needed to hold the gears in place. Reassembly was in reverse order of dissassembly.

My kitchenaid mixer is at least 37 years old. Everything has worked fine after all these years except the screw cap was flimsy, still stainless steel, but not sturdy. So I tried to replace it , but was told it was too old and couldn't get the part. I contacted Part Select and found a screw cap from newer models fit perfectly and should outlast me and the mixer, it is a lot sturdier than original one. It also arrived in 2 days, which was fantastic. Thanks guys

We:
tipped the mixer over on its side
pulled the old feet off
put the new feet in place and pounded them w/our fists
set it back up on its new feet
smiled

just took the unit apart and replaced the worn gear and bracket . Then took the old worn gear and bracket apart and replaced the worn gear . Then put the assy back together and now I have a spare

remove 6 screws for top of unit, remove gear assymble (23 screws), reassmbly and test it works great

We followed the you tube instructional video. It was excellent with good advice that kept us out of trouble. My mixer works like new again.

first removed the dress ring by tapping it very gently.then drive the pin out that holds the beater plate on, now wiggle it off, then you can see the screws that hold the gear reducer on. remove them. take that off and you will see the housing that hold the worm gear. remove the 3 screws that hold it down . 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

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 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.

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.

I called my fiancée.
