Hi JO18395. I believe you meant to say the ‘gears’ are stripped... But, to answer your question you will need to go “under the hood” to determine which gear assembly has failed.
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 (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 K45SSW, and then select the file under Parts List (1) K45SSWH0.pdf (341.41 KB) (be sure to check that it 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. 8, Worm Gear, in Illus. No. 38, 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 gears, etc. You may find more parts that need replacement than just a bad gear. You may also want to consider replacing all the grease, particularly if gear debris is suspended in it.
Besides any replacement gear(s) and grease you might consider replacing the gasket (Illus. No. 19) and “O”-ring (Illus. No. 34), too. I recommend using a food-grade grease that you can order online (although I’ve seen automotive bearing grease used too – your call).
It can be messy but quite gratifying to diagnose and repair your mixer yourself.
Here are some links to several excellent websites that detail the disassembling/greasing and 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.
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

How do i insert dough hooks into stand mixer professional 600??? There are no holes.


Your Flat Beater, Wire Whip and Dough Hook attachement ends should
look the same. They are inserted onto the beater shaft and held in place
by a single pin. The reason you cannot attach the dough hook to the
beater shaft because it is the wrong hook for your particular model.

KitchenAid stand mixer KSM50PWH. Was kneading dough with dough hook attachment and it quit turning. Motor works fine but the part that's supposed to go round and round doesn't. Can I fix this?


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.

The dough hook is stuck in the beater shaft of kitchenaid mixer


It sounds like it got overloaded when you last mixed dough. It will only come off the way it went on. If it has been bent on, it may need a bit of gentle encouragement.

Used the bread kneading hook, after 10 minutes, smoking


The mixer motor has probably overheated, as proper use and care was not being followed with the stand mixer.

Bread doughs are recommended to be mixed on speed 2 only and never for longer than 7 minutes. With the resistance of a bread dough that is provided against the beater, mixing for over 7 minutes may overheat mixer and cause smoking.

Please consult your use and care guide to refresh your memory about how to properly use your mixer for making bread doughs.

Bread dough hook slips when mixing


This is not a solution but I think you have a serious problem you might have sheared some gear teeth whent the mixer jammed and it only manifests itself under a heavy load, I would take it to a repair guy, those mixers are expensive and it would be worth it.

KitchenAid 600, Stand Mixer - Loud grinding noise, happened when mixing bread dough. When bowl is lowered (dough hook disengaged)....no noise, hook turns. When bowl is raised so that hook engages dough,...


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.

KSM5PS won't turn under load


Hi. Remove the top cover and look for the plastic transmission housing, it's toward the front of the machine. Look for cracks in this housing. If the housing is cracked, remove it and look for further damage to the worm gear assembly and the bearings and bearing seats that support them. You'll have to remove some of the grease to inspect the parts. If you're lucky, only the trans. housing will need replacement. If, like me, you're not so lucky, you may have to replace the housing, wormgear assembly, bearings and re-work the bearing seats so that the new bearings fit properly. Although Kitchenaid advertises that their mixers can easily handle bread dough, the truth is...They can't. This scenario happened to me and I had to replace all of the above. Be prepared to wait a month or more before your parts arrive. Specify that you want the METAL trans. housing. I'm still waiting (6 wks.), for a single bearing. If this solution works for you, please rate my solution. Good Luck! ricardok45

Beater jams


You are going to DESTROY YOUR MIXER by kneading dough with the flat beater. Read the directions. They spell it out in big letters. Only use the dough hook for dough; only use speed 2.
If the mixer generated enough torque to knead dough with the flat beater (it doesn't), it would tear up and overwork the dough. As it is, you're lucky you didn't strip a gear.
