KF26M2CCA5 KitchenAid Mixer - Instructions

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.

replaced planetary assembly. Was not difficult to do.

First and foremost, I am not mechanical at all. I typically refer to parts as thing-a-ma-jigs, and whatca-ma-call-its. When it froze up and started to make a loud grinding noise, I guessed it was a gear problem. I decided to try to take it apart, What did I have to lose? If I couldn't figure it out, I would be down a mixer. I was already down one as it was. It was very easy to take apart and I could immediately see what gears needed to be replaced. Parts Select made it very easy to see what parts I needed. And delivery was lightning fast; the next day after it shipped! I found a PDF on line on how to dis-assemble and re-assemble the mixer. I got it together and it mixed for a few minutes and froze again. I took it apart and realized that I didn't have the whatcha-ma-call-it (worm gear) seated properly. Fixed it and put it back together and put it to the test. Working just fine now! Thank you Parts Select for making this very easy!

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

Removed shroud and gear case top. No snap-ring pliers, so I used two small vice grips, one on each lobe, and spread and "worried" the ring up the shaft. Changed out all ghe grease in case of metal chips. Put it back tegether. Works fine.

This is a 6 Qt. made by Kitchen Aid Stand Up mixer 575. watts with 6 qt. bowl. A powerful machine. But not geared to crush Almonds. After about 2 quarts of Almond crushing to make Almond butter I heard the machine thumbing inside and turned it off immediately. Mind you, I am a 60 year old man with Maintenance Mechanic, and Machinist skills. If you listen to my instructions which aren't that hard you can do this. REMOVE THE POWER CHORD BEFORE CONTINUING. First you have to find the screws that hold the top half of the machine together. They are under the silver Kitchen Aid Stainless Steel 5/8th Band that runs around the middle of the machine. On the back of the machine is a small machine screw that when taken out removes the band. Remove the band carefully as not to bend it because it has to go back on looking pretty. Comes off easy. You will then see 4 longer 3/4 inch screws around the middle of the machine head. When you remove these screws the top half of the machine head will lift up. The top half of the machine head lifts off very easy. Throw all your screws into the top so you don't mis place them. You will see a Motor some gears on the side and a shaft that comes from the motor going into a Cast Aluminum Casing with another 4 screws 3/4 exactly the same size as the ones you took from around the top mixer casing. This is easy cause you don't have allot of different size screws only the one small one that screws on the back of the band. After these four screws are removed, again lift up the top half of the casing but this time it will be full with gear grease. Put the casing aside and using paper towels wife a little of the gear grease off the top gear. In order to turn the gear you must use the side drive gear or look around the gear you will notice in some of the gear slots will be shinny and worn. This is the Bevel Gear. There is a C locking shaft cliff that keeps the gear locked in. You must have a multiple C clip remover pliers that has different size C clips for the holes in the clip must be spread apart in order to remove the clip all the way up the shaft. NOTE:; DO NOT USE A PLYERS TO TRY AND PRY THIS CLIP OFF IT IS STRANG AND YOU MAY MAR THE STAINLESS STEEL GEAR SHAFT. You must use the gear C clip remover, I found one moderately prized for 25 dollars at the Home Depot or any large chain hard ware stores will have it. After the C clip is removed, slide the gear evenly up. If it's stuck that's only because of grease unless you mar the shaft by not listening to me. I also replace the Top Hum Bevel gear which is in the top half of the hub. Parts select has a Diagram that shows you the parts and where they are. When putting on the Bevel Gear over the shaft be sure to lower it evenly and guide it onto the worm gear. There is a small pin that sticks out in the middle of the gear make sure this lines up when setting the gear into the worm gear. The Top Bevel Gear, falls right out and you can use your figures to pull this one out and put the new one in. If you replace the Bevel gear my experience as a mechanics is to always replaces the adjacent gear as well, both will be worn. attach the C cliff the same what as taking it off except opposite. Pull the tow clip holes apart and slide it down to the shaft groove for the clip. Put everything back the way you took it off. One NOTE;.. DO NOT DO TOUGHT THE SIDE DRIVE GEAR IT IS SET IN WITH BRASE LOCKING SHIMS AND HAVE TO BE SET A CERTAIN WAY TO CLOSE. When closing make sure the Top Hub is in line with these brace shims. After screwing the hub back down do not over tighten, just snug it tight. Be sure to buy axle gear grade and replace any grease removed, this chamber must be loaded with grease. There is never too much only too little as you will wear the gears down without the proper amount. DO NOT TOUCH ANY THING THAT DOES NEED TO BE TOUCHED LIKE THE MOTOR OR DRIVE SHAFTS OR SIDE MAIN GEAR…

Ordered new worm gear and received in a few days. I cleaned out old grease from the gear housing, replaced the worm gear and packed with new grease. Machine runs well now. Easy repair.

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.

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.

We are a pretty handy bunch here. However, the diagrams provided with the part numbers did assist in the disassembly. It went smooth and easy.

___ Remove silver decorative band/1 screw ___ Remove top of mixer/4 screws ___ Remove circuit board/2 screws ___ remove 5 wires from ckt. bd. (be sure where they go) ___ Install new ckt. bd. with proper electircal connections ___ test mixer/OK ___ Reassemble & retest/OK

Following Replacement Part Youtube instructions, I disassembled the mixer and found what caused the sounds and prevented the mixer from operating. The worm follower gear had been ground down by the worm gear. I found that the shaft from the planetary gear had not been adequately greased and siezed preventing the worm follower gear from turning. The worm gear is obviously made of harder material and thus, was able to wear away the follower. I appreciate the your help which saved having to replace a perfectly good/expensive mixer. Thanks.

Took housing off, removed computer board and disconnected speed control assembly from board. Soaked plastic slide in hot water and freed up mech. Discovered a crack in plastic slide from forcing it. Ordered new assembly and installed. TIP: Keep slide clean of substances that will jam it by cleaning occasionally with water. For a complete cleaning you will have to remove it. Total of 6 easy to reach screws.

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.
