Please HELP! I don't know if I blow the motor when I removed the brushes (with the plug in) Or maybe the brushes are in the wrong way?? Many thanks

The Service Manual covering mixers with the control plate can be downloaded at:

http://www.kitchenaidparts.eu/documents/pdf/service-manual/classic-svc-manual-new-email-version.pdf

Things to consider:

The brushes have a chamfer on one edge and must be oriented so that the chamfer can pass a small stop in one corner of the brush sleeve.

Are all the wires to the control board connected correctly? The board is marked for the wires colors.

There are instructions in the manual for measuring the stator coils to find out if they are OK or not.

Checking out the armature is another whole thing and you can get information on-line about this (try searching "armature testing"). I really hope that you don't need to go this far.

If you look into the brush holder you will see a stopper at the botom ,(this is so when brushes are wore the spring is not driven into armature) .. the brushes have to be inserted so the groove is lined up , try that

hi

there is a ring clamp on top of the main worm follower gear on the drive shaft. you might not see it due to the grease.

you need to get one of those weird little pliers with points on them to spread the ring clamp to remove it. Then the gear is just friction fit on the shaft...it's pretty tight. I carefully used a screwdriver to slowly separate the main follower gear from the lower gear and it goes up the shaft....

after a bit you can wiggle the follower gear by hand and it will come up. Then you can see there is a pin holding the drive gear underneath it in place. The pin in my mixer was actually bent (must have been some tough dough).

then you reverse the process to put the gear back on -- except that the top follower gear has to go on the pin in the right orientation or the ring clamp won't fit.

buy your parts from mendingshed.com

hope it helps.

SOURCE: KitchenAid KSM5PSGR Stand Mixer - attachments not turning

Hi Gail. Kitchenaid no longer has a Parts List for your model. This means that they consider it obsolete. Do an Internet search for parts. You may get lucky. Good luck!

SOURCE: took brushes out to check and cannot get

Look at the brush from the side.. The surface that rides on the armature is curved> One leg is longer than the other leg. The long leg is the trailing and the short is the leading edge. Looking at the cooper end of the motor you can tell which way the motor rotates by the traces the brushes make. The leading edge will be on the clean side and the trailing edge is the side that is smeared black.on tthe copper. The long leg of the curve on each brush goes on the smearch side of those copper bars the brush rides on. Both brushes. Looking in the hole of the brush holders you will see what I mean. When you put the brushes in, you must make sure they are up against the copper and the springs are holding them down evenly.. You can lift the brush carefully and let it go to make sure it is working freely. Now, see if you can put an attachment on and turn it by hand. I'm not sure you will be able to so don't bend anything or hurt yourself.. Put the brush caps back on, remove the attachment and plug the mixer in.. Attachments off, fingers clear, turn it on. Does it run? If not, tap the mixer on its side with your hand.. Make sure the switch is on high. Tap it several times if need be. This is to straighten up the brushes to where the springs want them. When the motor starts turning, slight taps help. Keep it going until it picks up speed and let run for five minutes to seat the brushes. Let me know if it still won't run. I'll be watching for a comment from you.

SOURCE: k45ss kitchenaid stand mixer, i took out the brushes

jrichards - I hate it when that happens! It seems that power is not getting to the armature from the brushes so I would suspect that one or both of the brushes is (are) not seated properly. Did you remove the brushes to replace them or were you just inspecting them? I'd suggest removing them again and making sure the contacts are facing in the right direction to contact the armature. The concave contact face should be resting completely on the armature. If you've turned it 90 degrees too much, it wont' seat properly. I hope this helps... Howard, Burke, VA

I just replaced the worm gear in my Kitchenaid model ksm500pssm stand mixer. Now it only turns on when speed is set to 9 or 10. What might I have done wrong?

This is most likely has to do with either or both the control plate and control link. If the spring which goes from the control link to the control plate is not connected, the power to the motor will not turn on properly. This is most likely the source of your problem.

Take a look at the Service Manual which covers your mixer (even though it may not specifically reference your model):

Hi, I have a Kitchenaid stand up mixer custom edition 500 watt model #Kd2661xmc that sounds fine when I don't have anything in it, but sounds like its crying when I put just a single cake mix in it. ...

Get A Copy of the Repair Parts List for your model at Kitchenaid.com.
Remove the Gearcase Motor Housing (1) & the Transmission Housing (7)
Remove the 2 screws (23) holding down the Motor (2) and lift off way from
the Worm Gear (17). Test run the motor by itself at different speeds.
If it runs fine then it's time to inspect all the gears in the Transmission
Housing(7). Remove all the brown Grease covering the gears.
Pay attention in particular to the teeth of the Worm Follower Gear (19).
(the Bevel Gear (21) sits on top of this gear)
They should not be worn out or chipped. If they are then this is the source
of the noises you're hearing (the Worm Gear is grinding away the teeth of
the Worm Follower Gear). Once the Follower is replaced, your mixer will
be just as new again.
Please Note that this replacement is not an easy task. You need the right
tools and don't use a hard object like a steel screwdriver to pry out the
Planetary plate (15) from the beater shaft. Before re-assembly, use only
fresh new Food Grade Grease from Kitchenaid (the old grease may contain
metal filings from the worn out gear that will damage your new one)

I have a KitchenAid stand mixer model KT2651X. It recently ground down the worm gear follower, which I purchased a new one along with a new worm gear because this is not the first time it ground down that...

It is not a good idea to modify anything in the unit to make part(s)
designed for another model fit. The KT and KP models have different
part numbers for the motor. I still don't understand why do you have to
change motor in the first place, just because the Worm Gear Follower
has to be replaced. Something is telling me, you have just purchased
the wrong part (Follower). The KT2651x is similar to the KP26xxx
latest models and the Worm Gear does not come with the Follower.
(i.e. they are 2 different distinct parts)

I caught a spoon in my kitchen aid stand mixer. The mixer will not turn, and oil leaked out of the side

It sounds like you have lost some teeth from your worm gear. This usually happens when the mixer has been overloaded. The teeth on the worm gear are designed to fail first to prevent more serious damage. To replace the part you will need to open the head on your mixer. The gears are at the front of the mixer packed in grease. It should be obvious that the worm gear has broken once the head is open. If it is not the worm gear, with the head open it should be easy to spot the problem. The gears are available as spare parts from several places on the internet. search for "kitchenaid worm gear".

When you replace the worm gear, you should be able to see if you need more grease. This will have been the "oil" you saw escaping.

Just replaced the worm gear and cleaned out old grease adding clean new grease. Plugged the machine in and it will not run at all. The machine had been working but not well since I had stripped the worm...

Hi PEGNGEORGE. I can understand your frustration after getting all that work done for the gear and grease replacement just to find that it won’t run. Makes you want to scream. But before screaming, let's see what might be causing problems.
If your machine is not getting power to the motor, and you’re confident that the motor was not damaged by the stripped worm gear, which necessitated the replacement in the first place, then there are a few things that we can look at.
The easiest to check are the motor’s brushes. During your disassembly, did you remove either or both of the motor’s brushes (from the side of the mixer’s head)? If yes, then you need to check their alignment on the armatures’ commutator. The concave contact face should be resting completely on the comutator. If you've turned it 90 degrees too much, it wont' seat properly and you'll get no 'juice' to the electric motor so it won't start.
If the answer is no, and you said the mixer worked, but not well after the worm gear stripped, that would lead me to suspect the problem most likely will be with your speed control assembly.
Since you’ve already replaced the stripped worm gear, I imagine you have your mixer’s Parts List manual on hand, but if you don’t, you can download a PDF version from the KA website: http://www.kitchenaid.com/flash.cmd?/#/page/home.
Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case use K45SSW, and select the file listed under Parts List (1), K45SSWH0.pdf (341.41 KB). Check to ensure it matches your mixer model.
Turn to pages 6 & 7, titled: Motor And Control Parts, which provides an exploded view for the disassembly and reassembly of your mixer’s electrical components, along with all the parts. You’ll want to focus on Illus. No. 25, Control Plate Assembly.
First inspect around the control plate assembly to ensure all the wire connections are OK. It's possible a connection has come loose. Unfortunately the whole controller assembly is fabricated on a little PC board which was not meant to be 'home fixed', and my 'expertise' ends there. A local small appliance repair shop should be able to determine if the controller assembly is functioning properly or not, or you can just order replacement parts without the testing.
As far as parts go, here are four potential vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com. Prices for the same part can vary widely between vendors, so do your comparison shopping.
You may already know about the website links below when you replaced your worm gear, but it’s always good to keep these sites in your ‘toolbox’. Here are some links to several excellent websites that detail the disassembling/reassembly of a KA Mixer.
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.
Good luck and have fun. I hope this helps. Howard, Burke, VA

Kitchenaid artisan mixer does not turn the blade at low speeds

If it is the worm gear then the planetary will stop turning when there is a load on the paddle but the motor will continue to run at the speed you set it at. I'd be checking the carbon brushes, checking that the field assembly has not loosened up a bit and then I would see if the speed control plate adjustment screws are loose. I'd then reset the speed and see if it stays as it should be.

Repairing a kitchenaid 6qt mixer and replaced worm gear. parts list shows a thrust washer needs to be there but it won't fit. after a closer look it appears that I have two back bearings for the worm gear...

Hi. Go to the whirlpool.com website, for some insane reason they don't list their mixers, enter a search for mixers, then find your model #. Look for a parts catalog. Look at the "exploded" drawings for the transmission area. There you'll notice that there are Front and Rear bearing locations. This drawing also shows the correct place for the "washer". Also, the front and back bearings may look alike, but the're not. Every part needs to be in it's correct place or damage will occur when you start it up, or when you place the machine under load. Let me guess...The original PLASTIC transmission housing broke causing damage to the worm gear assembly. If this is the case, your replacement transmission housing should be made out of metal. If it isn't, call customer service and demand that they send one. The plastic housing has no place in a Premium priced mixer, especially when they advertise that the mixer can handle heavy bread dough. Finally, check the bearing seats, when the worm gear failed it may have also damaged these seats. It happened on my Kitchenaid. Good Luck!
