4KB25G1XOB5 KitchenAid Mixer - Instructions

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.

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.

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.

replaced planetary assembly. Was not difficult to do.

Simply placed it in the slot and pounded until firmly in with a soft mallet. Thanks to your site I was able to find the piece easily and very inexpensively. Thank you so much. I would die if I couldn't fix this machine.

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

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.

Easy thanks to your instructions

ordered the part and put in in with the help from the instant repairman

Open the case, removed gear cover, removed planetary drive shaft and gear, replaced with new planetary and reassemble.

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.

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

watched the youtube video on how to repair a Kitchenaid Pro 600.

replaced Speed control board. less than 40.00 took ten minuets from the time I started until we were making cookies.
