4KB25G1XGA5 KitchenAid Mixer - Instructions

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.

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!

The KitchenAid is "old school" in that it is held together with simple (but very stout) bolts and screws. I removed about 10 such fasteners, slipped off the gear retainer, and pulled it out. On Sunday, a very nice customer service rep helped me order the right part, but I did the rest on line in a matter of seconds. It shipped on Monday and arrived on Wednesday. Took about 10 minutes to put everything back. I REALLY WISH everything was this easy in 2012!!!

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.

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.

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!!

I looked on line found the product sent in information and 3 days later was in my mailbox,great service and ease of ordering. thanks marjorie

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.

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 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

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.

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.

First of all, go to the web site and download the schematics of the model #. It will show all the parts and part #s. Secondly watch a u tube video of the actual strip down process of the professional 600 series stand mixer. With this knowledge, do one of two processes 1: strip down the machine, remove the gears and check for defects- order parts. Or 2: replace all the parts( little money) and have a totally refurbished , smooth running mixer. I kept the good used gears for spares. I replaced 90 % of the internals ( including motor) and have a smooth running machine. I initially burned out the mother 2 months after initial purchase, sent it back under warentee, and received it back . Wen I stripped it down 10 years later, there was very little grease in the gear housing. This is what probable ruined the gears. Use plenty of grease in the housing and gears. The grease is one of the most expensive items, but you can't find it anywhere, so order it, along with everything else, from Parts Select.

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.
