KM25G0XWH4 KitchenAid Mixer - Instructions

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.

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.

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.

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.

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.

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…

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.

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

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!

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.

After removing the single philips screw from the back of the unit, the metal band will come off. Under the band you will find 4 phillips screws. Remove them to get the cover off of the unit. Once open, access the gear box in front by removing the four philips screws holding the gear box cover down. Remove any old grease from the unit as there may be pieces of broken gear in the grease that will damage the new gears. I used a small plastic scraper, some paper towel, rubber gloves and q-tips to get all of the grease out. Try to make a note of how much grease you removed and from where, so that you can replace about that amount later and in the correct spots. To remove the bevel gear remove the split ring holding the bevel gear down on the vertical drive shaft. Once the ring is removed it will be easier to move the bevel gear, but I found that it was somewhat press fitted on the shaft and I needed to use some channel locks to gently rock it back and forth to get it moving up the shaft. I then, also, (since I was in there) replaced the worm gear underneath the bevel gear by tapping the retaining pin out of the hole above the worm gear and then tapping down on the vertical drive shaft with a hammer to push the planetary gear down and out of the unit. Once free, I then regreased the planetary and reinserted it in the holder taking care to align the gears on the shaft and the panetary housing. Then I tapped the worm gear all the way down to the base taking care to keep the recessed notch on the top of the worm gear parallel to the pin hole above it. Then I replace then pin and tapped the bevel gear down onto the top of the worm gear and replaced the split ring. Realigned all of the horizontal and vertical gears and then repacked the grease. Closed up the gear box and test ran the unit on low. THen closed up the rest of the unit in reverse of opening.

Noticed worm gear was worn out, ordered the parts, it came very next day. On YouTube instructions were very easy to follow. Important point to remember,I washed the parts in water with chlorine in it. Retaking ring was tough to take out, as I did not have parrot beak plier, could not find it at Home Depot or Lows. Putting the retaining ring I used circular nut driver, to press it on the shaft to slide down by hammering it. While assembling follow the instruction step by step from the you tube. Machine works smoothly. Performing well. Thanks to part select, excellent web page, efficient delivery. I would recommend them to all.
