4KV25H0XMC5 KitchenAid Mixer - Instructions

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.

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.

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.

the plastic covering the thumb screw cracked almost half way and lost the piece....so the new one is being used to replace this old one...very easy to install

I had previously ordered several other gears after I found one of the worm gears stripped. After putting it all back together, the one major gear in the unit that I had not replaced because it looked fine, the bevel gear, also stripped. Learning experience: this is a unit worth several hundred dollars, so don't skimp on a $4 part. Once you work on this thing, you might as well spend a few bucks more and replace ALL the gears - even if they look like they are okay. Furthermore, if you only take 15 minutes to do this repair, as some on this site suggest, you are probably not cleaning the old grease carefully enough. Make sure you properly clean out the old grease to remove any metal from stripped gears, and use a good quality grease to re-pack the gear case.

took mixer apart down to removal of gear case cover.upon removal of this cover found the bevel gear and hub bevel gear chewed up .removed them both then replaced them both.and also had to solve a clearence problem between the 2 gears they were too loosely meshing. so had to push the hub retainer closer to take up the meshing slack.not sure my repair will hold but i have another set of gears and another solution that will surely fix it.

Used the meat grinder attachment, with the retaining ring too tight for the motor to turn the augur, so a gear stripped and the mixer would not run. I opened the mixer top, removed the transmission cover, removed enough grease to diagnose the problem (6 teeth stripped off the steel worm gear). I ordered a replacement steel worm gear and, while I was at it, a new retaining ring, bevel gear, retaining pin and the large planetary gear, as I could not tell the condition of these until I disassembled the whole gear train. I then removed the gear train components (needed a snap ring pliers to remove the retaining ring -- I don't recommend trying to remove it with an y other tool), washed them in acetone, cleaned out the transmission case and went over it with a magnet to get stray gear tooth remnants, replaced the worm and bevel gears and reassembled, using the original planetary gear, retaining pin and retaining ring. Filled the bottom of the transmission with planetary grease first, then, once the gear train had been replaced, slathered a big pile of grease over it, replaced the transmission cover. The machine then ran perfectly, so I replaced the mixer's top cover and decorative band and was back in business mixing with it about 30 minutes after cleaning the last of the grease off my hands. I should mention, I used a LOT of paper towels for this job. This was a fun job and I was sorry that it was so easy to do, as I enjoy working with gears and grease.

removed cover. Removed cover over gears. Used lock washer pliers to remove lock washer. Took out gears. Cleaned metal shavings from old gear and grease. Reassembled using new gear. Took about 15 minutes and saved $$ over sending mixer out for the repair.

I unplugged the mixer, then I removed the Phillips screw holding the beauty ring, then removed the 4 screws that hold the motor housing together. I removed the housing top, and unscrewed the speed control switch. I marked each one of the connectors of the switch (there are 4) 1-4 then disconnected the speed sensor from the switch and the motor. Replaced the new sensor and connected that to the new speed control switch. reconnected the connectors to the terminals I took them from ( 1 - 4 ) screwed it into place. replaced the top motor housing, I screwed that back with the four screws. replaced the beauty ring and screw. plugged it in and tested it and it was like new

Removing the cover of the mixers "guts", it was immediate evident the a major gear had lost a few of its "teeth". Parts Select clearly offered the required part of this $300 mixer for a favorable price. I was fully impressed that it arrived within 4 days or my ordering the part. I simply exchanged the damaged gear and restored the mixer to service and I'm fully impressed with the Parts Select Company for their swift response to my needs.

remove the cover,take out four screw from gear box,remove the gear box,clean all gears,then you see damage gear,replace it ,install new grease.

Removed one screw to remove deco band around mixer body. Removed four screws under band to remove mixer top. Removed two screws holding switch. Removed wires one at a time putting them in the same position on the new switch. Re-attached switch, mixer top, and deco band. Works perfectly.

I have to thank you at Partselect.com. You happen to help me help other people. Now I have several people bringing me their Kitchenaids to me instead of sending them in. I replaced two worm gears on a Kitchenaid 6 and the Hall sensor on a Kitchenaid 5. Very easy to do. Next week I have another Kitchenaid 5 to replace the motor on. Thankyou again for having the parts I need

Looked at the schematic for this model on Parts Select. Removed Aluminum band screw, removed the 4 screws that hold the top of the mixer. Lifted the top off. Removed 4 screws and lifted the gear case. Removed snap ring and took off tapered gear. Removed pin and removed worm gear. Picked out the metal, in the grease, from the old worm gear, using a magnet then inserted new worm gear and put it back together in reverse order. There was plenty of grease and didn't need to add any.

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
