It actually can be a couple things1 the worm gear2 the worm follower gear3 the thrust bearing4 the transmission cover5 the bearings on the worm gear front or rear6 the planetary main gear 7 the planetary shaft gear

You will have to open up the mixer and clean each of those to check them out. On the KV25 all are easily do-able just have a large work space and a lot of paper towels. This is a very serviceable machine. let us know what else you need.

Hi. Stop using your mixer. If your mixer is still covered by warranty, call Kitchenaid Customer Service, they are very good with warranty repairs.

If your mixer is out of warranty, remove the silver band that surrounds the top of mixer. Remove the top cover. At the front of the mixer, locate the transmission housing which is now exposed. Examine this housing carefully for cracks. If you find cracks anywhere in this housing, you have found the under-engineered plastic transmission housing. Kitchenaid's replacement housing is made of metal. Your plastic housing has no business being in a mixer that is marketed as being able to mix bread dough. It cannot!

If you're confident that you can make the repairs yourself, go to the Kitchenaid website and download the parts drawings. Remove the Trans. housing, remove the worm gear shaft assembly which is driven by the motor.. Remove and save as much grease as necessary to thoroughly inspect the worm gear. Inspect the worm shaft bearings. Look for cracks, or missing pieces on the bearings. Look for crunched cogs on all gears. Be prepared to wait at least a month for your parts to arrive after you order them. The replacement grease should be Shell Darina 2, or Chevron FM ALC EP 2.

If you're not confident about repairing this yourself, call Kitchenaid and determine the nearest "approved" repair shop.

You may be able to pressure Kitchenaid to pay for the damaged parts in your mixer. They are still installing these plastic Trans. housing on new mixers. Insist on a metal cover when replacing. Apparently, Kitchenaid feels no shame in their manufacturing process, and will not issue a recall notice for these housings. They are substandard at best.

If you found this solution helpful, please rate it. Good luck! ricardok45.

SOURCE: Kitchenaid Household stand mixer. Model no.

it is hard to tell you exactly what it could be, but a common problem is after a while the transmission gasket does deteriorate and will begin to leak oil.the gasket is part number4162324. the rattling noise inside your unit is most likely cause by a chipped gear inside, this can happen when the unit is put under heavy loads, such as dough. this problem could get worse as there may be fragments inside that will damage it more.hope this helps

Thanks

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.

Thank you for choosing FIxYa.com

The Nylon Worm Gear has stripped. This is designed into the part so if the Mixer gets overloaded, it won't burn out the motor. Which is odd if you have the reset switch like I do.

Part# 4162897

Don't worry about the Worm Gear for now. You have to make sure that the Motor
is fully functional by itself: Remove the Transmission Housing Cover (4 screws) and
the two screws holding the Motor down. Lift the Motor off the Worm Gear and set it
on the side (be careful of AC voltages from the Motor and Control Assembly).
Select Stir setting and observe the motor shaft. Is the Motor running? If it is,
Select other speeds to see how the motor performs.
With the motor now fully functional, you can now check the Worm Gear Follower
for worn out/broken teeth. Remember the motor drives the Worm Gear, it then in
turn drives the Worm Gear Follower (you may have to remove the grease to see it)
The Bevel Gear sits right on top of the Follower and drives the Attachment Gear.

Kitchenaid Mixer Planetary becomes sluggish when met with resistance.


The problem will be with the worm gear, if the gear is not stripped then check that the locating pin for the worm gear is not broken or missing. Occasionally the plastic gear can detach from the aluminium boss between plastic and shaft. The worm gear is the 99.9% place where drive can slip. Afterthought, I suppose the planetary pin is not missing or broken??

The motor is making a grinding noise. The mixer still works, it just sounds weird.


I have fixed many mixers with the same problem. The only part that consistently wears out
is the Worm Gear Follower located inside the Transmission housing. The teeth are wearing out
and becoming chipped. The grinding noises you hear are made by the Worm Gear and the
Follower. As time goes on, the metal filings from the damaged follower will eventually destroy the Follower and the Planetary will stop rotating.
Sooner or later that gear need to be replaced. Also remember to use new Grease after
a new gear replacement (metal filings from the old gear will damage your new gear)

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.

Trying to replace the gear worm on a kitchenaid mixer ksm5ps


Hi. Go to the kitchenaid website, search for the parts catalog for your model of mixer. Download the file and use these expolded diagrams to get to the worm gear shaft. You'll have to remove and save the grease when you remove worm gear. This is a messy, but necessary job.

You don't say what caused the worm gear failure in the first place. If you were making a heavy bread dough when it failed, you need to look further than the worm gear.

Once you have removed the top cover of the mixer, look at the now exposed transmission housing at the top front of the mixer. If this is a plastic housing, check it carefully for cracks. If you find cracks anywhere on this housing, you have discovered Kitchenaid's cheap plastic housing. If your warranty has expired, remove this trans. housing. If you've never done this type of work before, I recommend that you take a digital photo at every stage of part removal, as these photos will help you when you re-assemble the mixer.

If you find that the trans. housing has cracks, this is the direct cause of your worm gear failure. You must check for further damage to the worm gear bearings and their seats. Look for cracks and/or pieces broken off of these bearings. Re-assemble in the reverse order using the photos and the drawings to guide you.

Be prepared to wait for a month for your parts to arrive. Insist on a new METAL housing for the under engineered trans. housing. Kitchenaid is now owned by Whirlpool Corp. The product is but a shadow of the way Hobart used to manufacture these mixers. If this solution has assisted you. please rate it. Good luck! ricardok45

Hobart A200 mixer motor worm gear


sometimes you read of other problems and solutions and it puts you at the edge of your seat. in this case of changing the worm gear on the A200F was cake. when you drop the lower end (3/4 acorn and jam nut), pull out yoke (speed select handle) the center transmision shaft and gears pull right out.worm gear easy to change at this point. if you can change a motor bearing, then you can do this job. Note: change seals and bearings as needed,check all gears,keys and spacers for wear and if you go the mile take gears off drive gears, these are the 2 smaller trans shafts put in lath if you have accsess to one if not roll shafts on flat surface to see that shafts have no bends in them. Also remember when you put the bottom back do not over tighten the jam nut,hold and lock acorn nut, should spin free and have about .016 to .030 movement up or down. Lay out all part on cardboard the way they came out. should go back together easy.

Replacement parts for Wolfgang Puck stand up mixer


Very close; stand mixer parts (included accessories and manual only) can be accessed from this page:
http://www.wpcookware.com/categories.asp?cat=32
Just select your mixer's part number (located on a sticker inside the base) and click the link for a list of available parts. You will have to create an account to see anything useful, but all they ask for is your name, a password and an email address. When adding items to your shopping cart, be sure to check the 'Select Item' box. The ordering page will ask for the usual info. Prices are reasonable, but beware the shipping cost!
