If you haven't solved this problem yet, I have a couple suggestions.
Take off the motor housing, be VERY careful where the exposed electrical contacts are, then plug it in and turn on the motor with no gears attached. If it spins, cycle through the speeds to make sure they all work, then if they do, revisit your gears. Turn them all by hand and make sure they move easily and smoothly. Make sure the teeth aren't too worn down. I don't know what model you have, but also check anything that holds gears on or in place to make sure they aren't loose or cracked.
If the motor does not spin, look at the brushes (you could start by doing this if you wanted to, since they are far easier to take apart than the motor housing, but my guess is this isn't the problem). If the brushes are worn down to near the spring, buy new ones. If the brushes look fine, then either get real brave and pull open the motor to look for broken or worn out parts, or call an electrical engineer friend, or send it off to kitchenaid or a repair shop.

I have this problem too -it is rather common if you search the web. There was a suggestion posted on this site about what to do. See http://www.fixya.com/support/t125253-mixer_leaking_oil I have also read about other people taking it to a Kitchen Aid repair place where they repacked the grease for about $45. I took mine apart and there is gobs of grease around the gears. Right now I am still trying to figure out what to do. I am going to have my father look at it to see what he thinks since he is good with motors. The Kitchen Aid web site says that the grease is FDA approved, so at least it's not going to kill you if a little gets in your food. Their suggestion is to take it out and run it for about 5 minutes at least once a week. They say it leaks if it is not used often enough. That logic doesn't make much sense to me, but you could try it. Mine seems to leak more when I run it because the grease heats up and liquifies more. I hope that helps. I'll let you know what happens with mine, once it's fixed. Lisa

SOURCE: Kitchen aid mixer drops metal shavings in the

Hi REDLACQUER. Sorry to hear about the metal shavings. This is probably not to best way to take iron in your diet... My first thought would be to ask if your mixer is still under warranty. If you’ve had the machine less than one year, then I’d let KA replace your mixer with a new one. However, I suspect like many who seek assistance from FIXYA.com, your mixer is out of warranty, so what can you do?
Have you been able to find exactly where the metal shavings are originating? From the symptoms you describe, it appears that the planetary/agitator shaft assembly may be rubbing against its housing and generating the metal shavings at higher speeds. Have you noticed any increased noise levels/squeaking/screeching when the planetary rotates? It’s also possible that the planetary is out of alignment and not rotating true. Could the agitator shaft been jarred or hit hard during set up or moving in or out of you storage cabinet? Or the shavings could be symptomatic of other internal gear problems, but that would be the least likely scenario as the mixers internal gears are pretty much self-contained.
The good news is that this can be troubleshot and fixed quite easily (OK, maybe with a little effort) by yourself if you are a DITY type person, and feel adventurous. However, before you start to disassemble your mixer, be sure you have the Parts List manual on hand. If you're lacking one, you can download a PDF version from the KA website at: http://www.kitchenaid.com/flash.cmd?/#/page/home.
Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case, KP2671, and select the last file, KP2671XWH3.pdf (325.07 KB) listed under Parts List (24) (check to verify that it matches your mixer model).
Turn to pages 4 & 5, titled “Case, Gearing and Planetary Unit”, which provides and exploded view for the disassembly and reassembly of your mixer, along with all the parts. I suspect your Planetary Assembly, Illus No. 15, is rubbing somewhere against its housing, Lower Gearcase, Illus. No. 24.
To gain access to these pieces you’ll need the following tools: a regular or Phillips screw driver, retaining clip pliers, and a small drift pin punch and a small hammer. You need to remove the Transmission Housing (Illus No. 7) and remove all the lubricating grease from the transmission housing and gears (when removing the grease be on the lookout for shavings in the grease which would indicate excessive gear wear). This will allow you to remove Illus No. 25, 21, 18 & 19, Retaining Clip, Bevel Gear, Retaining Pin and Worm Gear Follower, respectively.
Once you remove the Retaining Pin (Illus. No. 18) the Planetary Assembly can be tapped down through the Lower Gearcase Assembly (Illus. No 24). With the Planetary removed, you can inspect it and the inside of the Lower Gearcase to determine where the shavings originated. Be sure to look closely at the Planetary Gear in the lower gearcase as well as the Agitator Shaft Pinion Gear (Illus. No. 12). That will also identify what parts need to be replaced, which you can order online.
You’ll need to replace the grease you removed with new grease. You should use a food-grade grease that you can order online (although I’ve seen automotive bearing grease used too – your call). Do not try to reuse any original grease as it may have ‘debris’ in it.
Here are five potential vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com; and Grainger.com (for grease). You should search for ‘food grade grease’. Prices can vary widely between vendors, so do your comparison shopping.
It can be messy but quite gratifying to diagnose and repair your mixer yourself.
Finally, here are some links to several excellent websites that detail the disassembling/reassembly of a KA Mixer. The mixers displayed in the links are different KA models, but the principles are the same.

Between these three websites and their excellent pictures and descriptions and your Parts List manual, you should now be able to completely disassemble and reassemble your mixer.
I hope this helps. Howard, Burke, VA

SOURCE: my kitchen aid mixer will not mix....the motor is

Hi AKRAUSSFAN, I hate it when that happens! From the description of your mixer’s symptom your mixer’s had a transmission failure in the primary gear box or the planetary gear assembly (agitator). One of the main gears has failed, hence the loss of power to the agitator, while the electric motor still runs.
The inspection and troubleshooting of the mixer transmission is a DITY capability, particularly if your mixer is out of warranty. Just be sure to have the correct Part List manual around when you start to disassemble your mixer. If you're lacking one, you can download it from the KA website at: (http://www.kitchenaid.com/flash.cmd?/#/page/home).
Click on Customer Care>Locate Manuals& Guides> and enter the 6 character model number, in this case KSM190P, and then select the file under Parts List (61) KSM150PSWH0.pdf (773.44 KB) (definitely check to see if this matches your mixer).

Turn to pages 4 & 5 titled: “Case, Gearing & Planetary Unit”, for the disassembly, troubleshooting, and reassembly of your mixer, along with all the parts. I suspect your culprit gear is Illus. No. 6, Worm Gear, in Illus. No. 27, Worm Gear Bracket and Gear assembly. KA designs this gear to fail on purpose so the rest of the mixer will not self destruct.
Once apart you can check for any other unseemly wear and tear on the other gears, etc. You may find more parts that need replacement than just a bad worm gear. You may also want to consider replacing all the grease, particularly if there are gear particles suspended in it.
Besides needing a replacement worm gear and grease, you might consider replacing the gasket (Illus. No 15), too. I recommend using a food-grade grease that you can order online (although I’ve seen automotive bearing grease used too – your call).
Here are five potential vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com; and Grainger.com (for grease). You should search for ‘food grade grease’ online (although I’ve seen automotive bearing grease used too – your call). Prices can vary widely between vendors, so do some comparison shopping.

Between these three websites and their excellent pictures and descriptions and your Parts List manual, you should now be able to completely disassemble and reassemble your mixer.
If you feel this is beyond your capabilities and will be too difficult to do by yourself you can take your mixer to a local small appliance repair shop and have them troubleshoot and fix your mixer. KA Customer Care can provide you with the name and phone # of the closest authorized KA repair shop in your area or you can do a Online web search, but be sure to get at least three estimates before deciding to commit to one repair shop.
Good luck and have fun. I hope this helps. Howard, Burke, VA

Where can I get the grease for my Kitchen aid stand mixer?


The grease is food grade grease and Kitchen Aid supply it as a spare part so depending on where you live either from themselves or an Authorised Service Agent. If you are in New Zealand then I can supply.

Motor clicks every turn


The clicking is probably a small nick in one of the gears, even the smallest chip can cause alot of noise or make the mixer click. Is the beater shaft still turning when you have a load in the mixer (bowl is full)
Or is it just clicking?

If the beater stops turning it is going to be caused by stripped gears, however if it is just clicking this would indicate just a nick in the gear. Either way I would recommend opening the mixer and replacing the damaged gear/gears.

Your mixer is considered a 5 Quart Professional, which means it has the same parts as a KitchenAid 6 quart mixer. The first thing you will want to do is take the mixer apart and disassemble the gearing. You will want to clean off the gears with paper towels and wd-40. Carefully inspect each gear once clean and replace damaged gears.

In the professional mixers when a gear strips you need to replace the grease and housing gasket, this is because the gears are all metal and there may be metal shavings in the grease which could cause the gears to strip again.

The most common gear to go bad in the Professional series mixers is the Worm Follower Gear (9706529). Here is a link to that gear on our website: http://www.mendingshed.com/wormfollower.html

Also, here is a link to the service manual for the mixer, this will aid you in taking the mixer apart and putting it back together correctly. http://lib.store.yahoo.net/lib/mendingshed/kitchenaid6qtservicemanual.pdf

We are one of KitchenAid's largest service centers within the US, and all parts we sell are genuine KitchenAid products. All parts are available at our website, www.mendingshed.com

Kitchen Aid 550 Pro Mixer New Worm Gear and Worm Gear Follower Issue


It would be helpful to get the model number and serial number off of the bottom of the mixer. This will help determine if the gearing has changed at all.

Usually when a mixer is making a lot of noise after replacing the gears we can find a small nick or gouge in the gear. even the smallest damage can cause these mixers to make a lot of noise. Also if you have an older mixer there was a change in the worm gear from 53 teeth to 60 teeth on the gear. If your mixer originally took a 53 tooth gear, and you replaced it with the 60 tooth gear it will make a lot of noise like you are describing.

So first check your serial number, if the first 4 digits are after WL45 your mixer would have a 60 tooth gear, however if it is a WL44 or before you would have originally had a 53 tooth gear and this is what is causing the loud noise.

If your mixer is new enough that it took the 60 tooth gear, then take the mixer apart, clean and remove all gears, clean them off with wd-40 and inspect closely, even the smallest chip can cause a ton of noise.

If you have any questions, or you cannot find the problem feel free to contact us at The Mending Shed.

Mixer turns but makes a clunking noise, stops on contact.


Hello Martyn,

I understand that you are having a problem with you Kitchen Aid K5SS. When the unit is on it is turning, when a load is put on it it stops. This is due to the gears in the head being stripped. However, we do not know what gears and how many are stripped without taking the unit apart. If you are not interested in taking the unit apart yourself, I would suggest taking in to a repair shop. If you are interested in taken the unit apart please post back to this thread and I will try and walk you thru it. However, if you want to locate a repair shop please post back your location and I will try to locate one for you.

Hello Suzann,

I understand that you are having a problem with your Kitchen Aid 5 Quart mixer. It sounds like you have stripped the gears or the worm gear out. Although, it may not be an expensive parts repair it is not an easy task to complete if you are not mechanical enclined. There are many different little gears in these units.

My suggestion would be to take it a local appliance repair shop that works on mixers. If you can tell me the city that you live in I would be more than happy to give you the location of one or two repair shops. As the unit is so old you want to invest in a new unit and keep that one as a reminder of how long Kitchen Aid has been around.

Kitchen Aid Mixer leaking grease around beater shaf


yes there are still pars avalible. the model will change but the internal parts are the same for the most part. there are screws on the back of the mixer. two on the metal band and one on the top of the motor houseing. open the mixer up you may want to disconect it from the base of the stand. to do this. see where greese is comming from. i dont think that it has a gasket you will see the gears and lots of grease you can take you finger and re smear the grease on the gears. but unfortunatly you may never get rid of the new noise. mine has been grinding for years. i use it 2 to 3 time a week. it works fine except for the noise which to me is not a big deal. if you need any parts you can get them from kitchen aid I hade to replace a gear once. (making to much pasta)
but they are easy to replace.

There are 2 possibilities, the attachments are worn out where they go on the shaft, simply replacing them could fix it, the other is the shaft is worn out inside the planetary ( where it spins), if it moves allot, 1/8 " or more from side to side, the housing is probably worn, and the planetary needs to be replaced, easy job, don't know cost, a new mixer may be in order.
