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

If you happen to have a friendly toolmaker with a small metal lathe it should not be too difficult to modify KITCHEN AID accessories that fit on to the front powwer outlet. However Puck Stand Mixer accessories are occasionaly offered on the Web. Meat grinders are very common and original Puck pasta maker have also been seen. Get searchin'!

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.
I hope this helps. Howard, Burke, VA

Hi TIOBEAN, by the symptoms you describe it appears the Center Shaft ‘O’-ring and quite likely the Transmission Gasket need to be replaced. You don’t mention how old your Artisan mixer is, but I assume it is out of warranty.
The internal gears of your mixer are factory packed with enough grease to last a 'lifetime'—whatever that means, and depending on the age of your mixer, where it was stored, degree and intensity of usage; these factors all contribute to the breakdown of the grease into its constituent parts (oil and suspenders), which have seeped beyond the gasket and ‘O’-ring, down the planetary (agitator shaft). Gravity can be very insidious. The residue coming from the agitator shaft is the gear lubricating grease oil that has come out of suspension.
So how bad is this oil leak problem and what can you do to fix it? First, if the amount of oil found leaking was small and if your mixer otherwise works normally with the missing oil you really don’t need to take your mixer apart to ‘fix’ it. The good news, though, is that you can take the mixer apart and 'fix' it, if you feel it is necessary.
It would be helpful to have the Part List manual as a reference. If you're lacking one, you can download a PDF version from the KA website at: http://www.kitchenaid.com/flash.cmd?/#/page/home. Having the Parts List on hand will also be helpful as you will have to disassemble and reassemble your mixer to replace the ‘O’-ring and gasket.
Click on Customer Care>Locate Manuals & Guides> and enter the 6 character model number, KSM150 and select the file KSM150PSWH0.pdf (773.44 KB) listed for your model that appears under Parts List (61), and save that file to your PC.
Turn to pages 6 & 7, titled:”Case, Gearing And Planetary Unit” and locate Illus. No. 28, Center Shaft & O-Ring; particularly Illus No. 15 & 16, Transmission Gasket and ‘O’-Ring respectively. I suspect these parts have failed and will need to be replaced. Now the real fun begins!
To get to the Vertical Shaft 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. After removing the Gearcase Motor Housing (mixer top) you will need to remove all the lubricating grease from the transmission housing and gears. This will allow you to remove Illus No. 11, 13, & 14, Bevel Pinion Center Gear, Pin (Vertical Center Shaft) and Groove Pin, respectively.
You should now be able to tap the Vertical Center Shaft (Illus. No. 12) down through the Lower Gearcase housing to access the ‘O’-ring.
Besides ordering a new ‘O’-ring (Illus. No. 16) and Transmission Gasket (Illus No. 15), you’ll also need to replace the grease you removed with new grease. Do not try to reuse any original grease as it may have ‘debris’ in it. You should use a food-grade grease that you can order online (although I’ve seen automotive bearing grease used too – your call).
With your mixer apart and the grease removed from the gears you can check them for any other unseemly wear and tear, too.
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.
