You have sheared a pin. Look at the parts diagram and examine the integrity of the upper dowel pin

Mixer won't start. Fell on its side and on/off lever was bent. Straightened and it now moves back and forth as it did before. I took out the two black screws at the top which hold in magnets on...

Make sure the Speed Lever and and the Speed Link are in place
and operating smoothly. The two Large black screws you are referring to
are the Motor Brushes Caps. The Carbon Brushes are keyed and
designed to be inserted into the Motor Housing but one way. If you
insert them in wrong, they will not make contact with the Motor Coils
and you mixer will never run.

All you have to do now is adjust the mixer speeds (if necessary):

Remove the screw holding the End Cover and locate the three screws from the Control Plate.
All three (2 top left and right, and 1 bottom) must be adjusted.

1. Loosen the lock nuts enough & Turn the 2 top screws clockwise until they cannot be turned
anymore. Leave the bottom screw alone for now.
2. Use a dab of white paint or paper whiteout to mark the positions of the Phillips screws.
3. Plug in your mixer and Set the speed selector to "Stir".
4. Turn each top screw One full turn couterclockwise (alternating between Left and Right)
Keep making one full turn at the time (for both left and right) until the motor starts running.
5. Put your hand near the Agitator shaft and allow it to brush your finger slightly. Use your
watch or clock and start counting the number of times the shaft touches your finger in
60 seconds. The correct count should be 60 RPM (Rounds Per Minute). If it is less
or more than 60, give each screw 1/4 turn counterclockwise or clockwise and start counting
again. Now tighten both lock nuts.
6. Set the speed selector to "6" and turn the bottom screw either clockwise or counterclockwise
to achieve a speed of 180 RPM.

For your reference, the planetary RPM's for the 5-qt. tilt-head Artisan Stand Mixer are as follows:
Stir speed - 60
Speed 2 - 95
Speed 4 - 135
Speed 6 - 180
Speed 8 - 225
Speed 10 - 280

Kitchenaid mixer leaking oil

Get a copy of the Repair Part List for your model at Kitchenaid.com
Grease inside the Planetary Assembly (the shaft is tight fit to the Planetary
plate at the factory and is not designed to be taken apart, so do not use
any hard object such as a screwdriver to separate them) over times can
turn to liquid and leak down the bowl. Removing the Planetary assembly
and adding Kitchenaid Food Grade Grease is not a task for a novice.
To properly remove the Planetary Assembly, you must work from inside
the Transmission Housing: Remove in this order: Retaining Clip(25), Bevel Gear(21),
Retaining Pin(18), Worm Follower Gear(19). Use a soft mallet to tap out the Shaft
of the Planetary Assembly(15). Re-assemble it in the reverse order.
Note: The Bevel Gear is extremely tightly fit on the shaft, and a pin punch
must be used to remove from the shaft.

Head of mixer is loose what do I do?

The Planetary plate comes attached to the shaft from the factory. It is not supposed to get
loose and come apart but it often does due to the mixer's vibrations and the user's constant
attaching and removals of the flat beater, wire whip or dough hook onto the beater shaft.
Try to remove the Planetary plate first : Gently rock it from side to side while pulling on it
to separate from the shaft. Notice the groves on both the shaft and inside the planetary
housing. That is how they are attached to one another at the factory (just friction, no screws
or pins). Now for a permanent solution:
Take a trip to Home Depot or Ace hardware and buy the J-B Industro Weld Compound
(Not the 5 minute type). Mix an equal amount from both tubes (Black and Red). Use a Q-Tip
and apply a thin layer of the mixture on both the shaft (grooved section) and inside the
planetary housing. Now re-attach the planetary plate to the shaft. Use a long strip of duct tape
to hold the plate in place (to prevent it from falling back out). Allow the epoxy to dry overnight
or at least for 8 hours.
The Planetary assembly is now permanently attached to the shaft of the mixer.

Planetary housing fell off

BRUCE, sorry for the initial solution... I had a total brain cramp of what you were describing and after reflecting on your original problem and then seeing your second entry realized what happened. You are absolutely correct that the planetary shaft is press fit onto the planetary housing. For whatever reason, I overlooked that.
I cannot explain why it the housing came of the shaft, but suspect that vibrations during its use caused the fitting to loosen and the planetary housing to fall off.
You have two options. Option #1) Purchase a new planetary assembly that includes the agitator shaft, which will run between $35~$57, plus S&H depending on the vendor or Option #2) try to reattach the planetary housing back onto planetary shaft. (BTW, if you reorder the planetary use the part number from your Parts List manual for your particular color and model, not the 9078036 number you found on the housing)
I suspect the planetary housing’s spline well has already been weakened and there may be micro-cracking which is not clearly evident so the refitting may or may not work. Of course it may be worth trying and fit back together without any problems.
Since it will be difficult to get good mechanical advantage by hitting the planetary housing back onto the planetary shaft while the mixer is upright, you will need to remove the planetary shaft from the transmission housing before you attempt to hammer the shaft back onto the planetary housing.
If you attempt to refit the planetary shaft back to its housing, place the housing on a piece of soft wood to protect the enamel paint before you start to hammer the shaft. Also use a piece of wood on the top of the shaft so you don’t accidentally damage the top of the shaft with your hammer. Good luck. I hope this solution was more helpful than my first one. – hslincoln, Burke, VA -

Planetary gear housing fell off.

Hi BHENDERSON_C, sorry to hear about your mixer’s malaise. The Planetary should not fall off! Something has failed inside the transmission housing to allow the planetary to drop from the head. It may not be evident from the planetary assembly, so you need to get ‘under the hood’ to find the point of failure.
It would be helpful to have the correct Parts List manual on hand when you start to disassemble your mixer. 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> and enter the 6 character model number, in your case, KP2671, and for starters, select the last file, KP2671XWH3.pdf (325.07 KB), of the 24 listed under Parts List (24) (NB: There are five different model versions of this manual, so check to see that it matches your mixer model. If it doesn’t try a different version).
To disassemble your mixer you will need a regular and Phillips screwdriver, snap-ring pliers, a small drift pin punch and a small hammer. By using the exploded views in the Part List manual, you should be able to disassemble, inspect, identify and replace broken/worn parts, and reassemble your mixer. The Parts list manual doesn’t provide that step by step assembly instructions that would be nice to have, but just a general idea of how all the parts fit together.
Turn to pages 4 & 5, titled: “Case Gearing And Planetary Unit” which shows you an exploded view of all the mechanical parts and assemblies for your mixer. You will need to remove the Transmission Housing and remove all the grease from around the gears to clearly see the parts. Inspect the grease for debris. I expect you’ll find pieces of the retaining clip and retain pin that hold the planetary to the mixer head somewhere in the grease.
After you’ve determined which parts failed, you will want to order replacement parts. Here are five potential online 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.
Also, here are links to three 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, troubleshoot, determine appropriate repair parts and reassemble your mixer to get it working again. Good luck. I hope this helps. Howard, Burke, VA

Kitchenaid 625 watt 6 quart mixer. Was using it

HAMILTONCOOL - It appears that your mixer had a mechanical failure in the transmission box or planetary gear assembly of your mixer failure - one of the main gears has failed, hence the loss of power to the agitator. You didn't mention any associated noise prior to the loss of power to your agitator, but I'm assuming there was just a little more noise than usual, prior to failure.
The inspection and troubleshooting of the 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. Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, and then select Parts List file. You can check the page titled 'Case, Gearing & Planetary Unit, for the disassembly, troubleshooting, and reassembly of your mixer, along with all the parts. It can be messy but gratifying. Once apart you can check for any other unseemly wear and tear on the gears, etc. Good hunting... I hope this helps - Howard, Burke, VA

We moved and the mixer fell on it side and oil came out of it. Its a Kitchen aid Artisan Model rrk150ww

nydadinga - Sorry to hear about your fallen mixer. This is not a tragedy, and after cleaning up the grease with soap and water, it should operate normally. Your KA mixer has internal transmission and planetary gears which convert the electric motor's rotation into the mixer's rotation. The internal gears are factory packed with enough grease to last a 'lifetime' (whatever that means), and over the course of your move the shifted mixer leaked the grease inside the transmission housing. You did not mention where the 'oil' was found. Hopefully it was not exuding 'oil' from the brush cover caps located on opposite sides of the body, but coming from the planetary (the part that turns with the blades under the body). I also don't know how old/how used your mixer is. The older the mixer, the more used it is, the more fluid the gear grease, and tend to seep from cracks and gaskets that aren't tight. Gravity can be very insidious. The inspection and troubleshooting of the inside of your mixer 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. You can download it from KA customer care. Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number and select the Part List file that is listed. I hope this helps! Howard, Burke, VA
