4KP26M1XLC4 KitchenAid Mixer - Instructions

Worm gear strips usually after the lower gear housing breaks. Tore down cleaned grease and shrapnel out, replace stripped worm gear and lower housing. It's convenient that the lower housing plate comes assembled with new bushing and gear. This is now the third one of these expensive mixers I have repaired, word got out that I fix them, and this is a very common problem. Repairs have been for friends and Church, so I don't charge any labor, it's kind of fun, messy, but fun. Note to Kitchen Aid: Please strengthen lower gear case.

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.

After trying to make a batch of heavy frosting, my KitchenAid mixer final stopped turning. After watching a video of how to change the grease in a similar model on PartsSelect and seeing it wasn't that hard to take apart, I decided to give it a try myself. Removing the cover exposed a completely worn gear drive. Luckily, it was easy to determine which parts needed replacing and PartSelect sent them in no time. Once I put everything back together, it sounded terrible which was pretty tough to take. As it turned out, the problem was flecks of metal from the gear were still in the grease and were getting caught in the mechanism. Once I thoroughly cleaned all the grease out and gave it some fresh grease the machine worked great. Much better than before. I only wish I had swapped the grease out at the same time. Thank you PartsSelect for saving me hundreds of dollars on a new machine!

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.

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.

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.

opened the mixer.. all screws in kitchaid are the same so not to worry... opened up and replaced the gears... and put it back together... diagram helped in that front and rear bearings of connecting gear are the same # on diagram it is easy to confuse when you put it back together, but the item number and description of each helped make sure it was in the right place. Otherwise... time to fix would have been less....

took mixer cover off, took gear box cover off, removed gears, replaced gears, replaced covers, made cookies, no problem!!

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.

Remove the top cover , inspect the gears . In my case the worm gear and the gear follower worn out . I removed the damage gears and the old grease , clean the inside and reinstalled everything . Now , the mixer is working good again.

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.

Easy repair that replaced the variable speed switch. The broken switch only ran at high speed. To replace the mixer would cost at least $500. The new switch was $45 and was an easy install. I marked the four electrical leads with a Sharpie and loosened the two screws holding the switch. The repair was super easy. It was like heling an old friend recover from an illness.

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
