repair is farly simple just take your time, First attempted i didnt replace the speed covernor looked ok but had problems getting slow end to work properly decided to go ahead and install since i purchased it also and walia took care of the cogging problem. Good Luck

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.

unscrewed the old one........screwed in the new one, no chance for electrocution or power tools..........darn!

Two flat head screws removed, swapped out the latch, and replaced.
The entire repair took about two minutes.
Price was acceptable given the worth of the mixer.

Just twisted it in to place. Parts Select was awesome! Thank you!

This is the tightening screw that holds the attachments into the motor unit of the mixer. Found your web site and reordered 2 replacement pieces (in case one breaks!). Very EZ and user friendly. Thank you!

As I was using my mixer the spring clip broke off. I immediately went to my computer and googled you. Twenty-four hours later the part had arrived and I installed it by removing two screws, holding the spring in place and replacing the screws. At the same time a repairman was in our home repairing our drier and I felt so empowered by my repairmanship that I nearly asked him to leave!
Thanks for your extreme promptness and readable parts chart.

A part required to operate the bowl lift had failed, "broken in half". I removed the base, by removing 4 large philips head screws, then removed the pedestal which housed the broken part by removing 4 more large philips head screws. I used a hammer and punch to drive out the split pin, a pair of pliers to remove the cotter pin and replaced the broken part.

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.

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

Separated the mixer head from the pedestal and base by removing four bolt/screws (It is not necessary to separate the base and pedestal) . Rotated the lift arm to the raised position (a screwdriver might come in handy since the broken part might impede access) and removed the cotter pin (using needlenosed pliers) on the broken lift arm. Then used a hammer and a small hex driver to punch out the lift lever retaining/actuating pin. This allowed me to pull out the lift lever and replace the broken part with the new lift arm. It was a simple matter to then replace the lift lever retaining/actuating pin and the lift arm cotter pin, and reassemble the mixer head and pedestal.

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.

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.

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.
