4KN15C1XWH1 KitchenAid Mixer - Instructions

Remove screw at back of mixer,remove metal sleve and remove three more screws (front and sides. remove screws and plastic cap of gear box then remove holding ring in post and remove damaged ring installation is opposed of removal.

Took screw off band. This revealed 4 screws to upper housing. Removed 4 screws and lifted upper housing off . To my surprise I found no screws holding gear housing cover in place. You could tell they were there at one time. Should be 4. I removed cover disasembled what was left of gears. Cleaned old grease ordered parts. Thought since there was only 1 screw on diagram it would ship 4. No big deal. After recieving parts further inspection revealed no screws holding motor in place. This blows me away. Anyway off to local hardware store for more screws. Got home slapped it togethere in 10 minutes. Ordered this off TV about 6 years ago. They must have had it in for repair and forgot to put it back together. All that aside it runs better than ever. Thanks much Michael

Ordered new paddle beater, rmoved old beater from mach, took new beater from plstc bag, inserted into mixer in appropriate plc, turned on mixer. YES!!

Removed top cover, remove snap-ring on shaft, slide top gear and worm gear off. Clean all the grease out and clean parts. Installed new worm gear and parts. Repacked with new grease, careful not to much, leaving room for expansion.

removed the cover as stated in the e-mail and followed their recommendations on how to do the repair, the hardest part was removing the retainer clip, job went smoothly. thanks

Watched the video. Ordered the parts. Watched the video again. Replaced the worm follower gear and bearings on the worm gear. Added grease. Installed new gear housing. Put it all back together and tested. Works like new. Now I get cakes and goodies again and have a happy wife who thinks I'm super handyman. Thanks

The appliances belong to my neighbor who had no papers/manuals so I was on my own to figure out how to even get the machine apart and to find the correct nomenclature for the parts I needed. The PartSelect diagrams on the web site told me everything I needed to know. The key to the dis-assembly was the band around the center of the machine. After I discovered that, the band came off easily followed by splitting of the casing. One the first machine it appeared that the circuit board/switch assembly was in bad shape looking like it had been over heated at one time. As a test, I took the electric component out of the machine that would run and put it on the dead mixer. Beauty, it worked. OK so much for the easy one. On the machine that would only turn part way, I split the transmission housing by removing four small bolts and found that the worm gear was partially stripped. So, I ordered a new gear, switch assembly and transmission gasket since the old one was torn during my dis-assembly process. I don't have any snap ring pliers, so the snap ring(retaining ring) was taken off using a large screw driver and a a pair of slip joint pliers. Worked well, but I was afraid that the old retaining ring may have been damaged, so I ordered a new one. Good idea, since I broke the old one trying to put it back on. When all of the parts were installed, I filled the voids with heavy grease and put it all back together. Both mixers now work perfectly which saved the owners several hundred dollars. They had planned on replacing them both for use at their restaurant. I am now a fan of PartSelect because of the ease at which I, a novice had been able to find and get the correct parts, and the speed at which they arrived. I am also very impressed with the Kitchen Aid mixers because it appears the they are very well made, and are easily repaired if they do break. I was surprised to find a small appliance that is repairable. Many are now just throw away quality. I am a hero to my neighbors (they don't know how easy this was) and will keep the refrigerator magnet that was included with my parts order, for future repairs.

removed the cover, separated the gear casing, cleaned the gears, replaced the thrust bearing kit and worm gear, greased all and reassembled. Wish I would have known to order the grease, it would have saved a couple bucks in shipping.

The transmission housing was cracked and one of the bearings was broken. I replaced both of them, but the mixer really didn't sound any better. So I replaced the gears in the transmission, and while that was better it still wasn't correct. I am going to replace the other bearing and the planetary shaft and see it that aligns everything a bit better. I believe the problem is the way the gear on the end of the motor shaft is working with the worm gear, the bearings are not keeping the correct spacing. Hopefully, the new one in the rear will fix the problem.

Remove Beaty band, one screw. Remove four screws holding top. Remove worm gear, by simply lifting it out. Removed all grease. Repacked with fresh grease. Take out gear case/ transmission bearing, clear all old grease, repack with new grease. Install into new gear case housing. Assemble, and Repack new worm gear and front and rear worm gear bearings, utilize old washers (2), and one small ball bearing washer. Rotate worn gear and bushing to spread the new grease throughout the gears. Replace top cover, four screws . Replace beauty ring, one screw. Run unit for 20 to 30 seconds, under no load to distribute the new grease. Works like a charm. 45 minutes to one hour. To complete.

Removed the cover. Removed the gear assembly cover.. Extracted the C clip with a tool. Removed the bevel gear. Pushed out the dowel pin. Used rubber mallet to push the shaft off the worm gear. Replaced the washer and the worm gear. Used a 1/2" diameter PVC, 3" long over the shaft and on the gear to push back the shaft through the gear with rubber mallet. Pushed back the dowel pin. Reinstalled the C clip. Replaced broken hub bevel gear. Added more grease. Placed the gear cover with 4 screws just tight enough to hold the cover but still allows movement. Turned the mixer to the lowest speed. Allow the cover to self adjust so that the gears have the smoothest sound. Tightened the screws while while maintaining the smooth sound. Turned off the power. Replaced the cover.

Great experience. Reasonable cost. Quick delivery. Would certainly use PartSelect again

removed top casing, removed old switch and sensor,and replaced with new ones. It was just a matter of a half dozen screws and unpluging 4 or 5 wires and then reversing the process. Couldn't be easier. thank you
