KitchenAid Mixer Repair - How to replace the Worm Gear

[@blakbuzzrd]

Without a doubt the most straightforward, easy-to-follow guide I've ever watched. Thanks to you, our mixer is aliiiiiiiiiiive!

[@Robsbrd99]

Just finished up surgery on my mother's mixer. Because of your video, I was able to make it right again and my mother very very happy. Thanks.

[@ellenholmes6162]

Found broken off pieces of the old worm gear in amoungst the grease. Just thought I’d mention to look out for that. Excellent video! Explained patiently and in plain language.

[@joshgoldberg466]

Great instructions! I was able to repair my 18 year-old KSP150. The only suggestion I would make would be to explain when the worm gear needs replacement, and to show a damaged worm gear. My mixer started to make a rapid clacking noise when it was turning. Fortunately, when I opened up the mixer according to these instructions, I saw right off that several teeth of the worm gear had been sheared off. Again, well done!

[@m_recordz]

Absolutely the best worm gear replacement vid out there. Camera angles, clear instructions, pleasant background tunes…everything led to me fixing my Kitchen-Aid!

[@douglasmartin1265]

Great video. I bought the whole worm gear assembly, on Amazon rather than just the gear, and used this video to repair and extend the life of our 20+ year-old stand mixer. Thanks for posting!

[@JensKoenig-x1r]

I really like your video, very good stepwise explanation, let me add a recommendation, if the worm gear is broken you really should remove all old grease and not reuse it, because the broken parts of the old worm gear (the dents) are partwise in the grease and you do not want to ruin your new wheel with this. :-)

[@phillipennis]

Just fixed my broken gear. This was up there with one of the best “how to” videos I’ve watched. Instructions were to the “t”. You do need to know how to use basic tools and have a little bit of a “handy-person” in you, but other than the messy grease, it’s an easy fix. Thank you! Never mind what that loser said about the ball peen hammer; appreciate a free video that shows how to do a job that would be nearly impossible to do w/o this tutorial. Kudos!

[@TomDandeneau]

Extremely helpful tutorial. Camera angles are very good. Explanations are clear and correct. Can't give this enough kudos!🙂

[@MarcoCasteleijn]

We went from a non-working machine to a working one! So happy for this video, so much cheaper than a new one :D Clear and easy...

[@annettechisholm495]

Excellent video. Repaired my KSM90 worm gear. I broke it when I jammed a wooden spoon in the paddle. So happy to have it working again. Thankyou so much.

[@montielhancock2279]

Thank you! EASY to follow instructions even for a non-mechanical type like me. My mixer is back in business in a little less than an hour. Thanks again!

[@andrewpearce3608]

I would like to add a note about the grease. KitchenAid mixers specify part number 4176597, which is a black colored BENALENE 930-2 grease. This is a grease designed to run at higher temperatures. Not all of the 930-2 greases are food grade H-1 registered with the NSF. The one made by Microlubol is, and the 6oz jar at Amazon is enough to generously grease your gears twice. This is a superior lubricant compared to the standard H-1 white gear grease, which I found to be almost immediately disappointing. When you take the mixer apart to get at the gears, clean it like crazy. Don't just wipe the old grease off, get down into the gear teeth with a toothpicks and an old toothbrush. Wipe things off with a lint free rag; you'll need several of them. Work the new grease into the teeth and coat the shafts and washers. Put things back together and spoon on even more grease. If, after all this work and carefully putting things back together, you find that the mixer runs a bit slow and might freeze for an instant once in a while, it's either because the grease is too thick or the replacement worm gear is NOT exactly the same as the factory part. Many of the imported gears are "close enough" but not exactly perfect. It may be the best idea to spend a few extra dollars and buy the OEM official KitchenAid gear. If you didn't do the crazy-level cleaning and find this stop & go issue, you may still have a bit of crud in the gear teeth. Take things apart, get the right parts and grease, and do it again the right way this time.

[@4hiltiman]

awesome, step-by-step instructions!! Well made, repair took less than an hour and was fun at that.

[@TheLegendOfMegaMan]

I have made my Mrs very happy today! Many thanks!

[@TheMickabob]

Great video, good pace, descriptive, nice close ups. Easy to follow for a successful repair. Just a note, some screws on my machine were square heads rather than flathead. Maybe an updated machine, or different screws due to being an Aus model.

[@adrianapulice9198]

My husband and I, along with you, tag-teamed and it is repaired!! Thank youuuuuu

[@elka5768]

I love your instructional videos! You have a clear and concise teaching manner that is easy to follow and understand. Thank you

[@xblfac3sh0t]

Thanks for the very clear video, KitchenAid back in business once again! Have some old shop rags and maybe latex gloves when you take the housing apart there's a lot of grease!

[@michadeutsch]

Excellent step by step guide 😊 it was quite easy to fix. Now my wife is happy 😅 Thank you

[@RustykPurple]

Thanks so much for the video. It was extremely helpful. I see others have mentioned it already, but it looks like at some point the phillips screws got switched out for square bits.

[@williamnash866]

Any advice on how to diagnose that this gear is the problem, prior to disassembly?

[@gianproenca]

Thanks for the video. It helped a lot when I replaced the worm gear and the grease on my wife's Kitchenaid mixer. The only problem I had was with the screws. The model Classic Plus, bought in the US, has square heads on most of the screws, instead of the regular flat heads. Not hex, not torx, but Robertson square. Fortunately, one of my smaller flat screwdrivers fit diagonally on the head and I was able to unscrew them. I'll try to find a Robertson screwdriver in a hardware store to tighten the screws a bit more next week. Otherwise, the video is spot on how to replace the worm gear.

[@mrock29]

This was great. Clear instructions with good video. Just fixed my sister in laws

[@dougkluth2207]

I repaired mine in one hour. I bought the entire replacement gear assembly. Thanks

[@mattl.3861]

Thanks for the video! I had an oil leak, and this helped tremendously

[@troyelisahughes1505]

Thank you your video was awesome. I was able to make the repair and fix the mixer. I have model KSM500PSSM0 Pro 500. the only real difference is two of the four screws could not be accessed unless the base was removed.

[@gooddempsey]

That was a heck of an insertion at 11:39 consider me a lifelong subscriber after witnessing such an event

[@brittonledingham]

This was so helpful. Thank you!

[@dauerv]

Very helpful and detailed. I was able to fix our mixer with the help of this video. Much appreciated!

[@jej3451]

Great video, thank you so much! I followed your instrucitons successfully. I have to say though, you make removing/inserting all those pins look way easier than it is.

[@jej3451]

Had to do this again after 5 years. This time I'm going with a factory part, so hopefully it'll last longer. (It's also important to obey the instructions in the manual about not trying to knead dough faster than speed 2.) It's important to fish out the pieces of the old gear, or just replace all the grease. You don't want pieces of the old gear getting ground up in the teeth of the new one.

[@goffrd137]

Totally worked for me. Thanks for the help

[@jimmerkle6962]

There are two washers, equal size/thickness, one on each end of the worm gear. Make sure you save the washers when removing the old gear and reinstall them, one on each end, with the new worm gear.

[@glendagibson3122]

Thank you, very professional.

[@markfischer150]

Hi. I replaced the worm gear on my mixer and it spins fine now but it slips when it encounters even slight resistance (but when I opened it, the new worm gear doesn't seem to be getting ground down at all). Any ideas?

[@straybricks]

Check the small metal drive gear at the bottom of the same stack where the nylon worm gear is. I had one where that metal gear ground itself down, the cost to replace the whole stack wasn’t much more than just the worm gear.

[@elipil9300]

great video sir

[@gwendolinesanderson8772]

Hi I m with you every step but i cant get the cant the housing off no wiggle at all. I also have the artisan. HELP

[@angelikathiele8351]

Is there any video explaininf how to change the center gear in a kitchen aid 5Ksm175? Thanks very much for an answer.

[@steveb6665]

Thanks. Saved me buying the wife a new mixer. ❤

[@jamescarpenter1553]

Perfect instructions ! Easy Peasy ;)

[@robertknight4672]

On Newer KitchenAid mixers you will need an S1 sqare bit for the body screws and a ⅛ hex for the pedestal if you choose to remove it although I typically find that's not necessary necessary on North American Tiltedhead mixers.

[@Ramentheawsome]

I saved a mixer from the trashcan becasue of this video, thank you very much!

[@aendjaifarrar2807]

thanks for the video great help!

[@mard7569]

Thanks for the video! I need to replace the worm gear for a K5-A, will any worm gear work ? Can anyone help? Thanks!

[@drcoolit]

that pin on the planetary section -- is that a tapered pin (unidirectional) or straight sided?

[@Firstscout_Adventures]

Just saved me $189. Thank you

[@lynnsewell1431]

what size punch should i purchase to make the removal of the pin easier?

[@michaelhorwitz4703]

Fantastic!

[@marcuslundmark9550]

Thank you for the excellent video. I'm working on a KitchenAid model K5SSWH serial WD2522320. It was making some odd noises. When I opened the top cover, I noticed a loose 10-24 nut in the electric motor compartment. It's a plain 10-24 machine nut. It fell off one of the stator hold down studs. I noticed the nuts on your mixer are the aircraft locking type (with the nylon ring)? Fix.com wants $23.88 for one lock nut? Are these available at the local hardware store? Are there enough threads to engage the nylon locking ring? Or just put the plain nut back on with some red bearing grade Loctite?

[@janessagrant]

I put the worm gear back it but it's really rough to spin still. Seems like the long piece that goes through the centre of it has resistance for some reason. Even without the worm gear in, just spinning the other gear in place, it's got resistance to turning....

[@JAMaxeRestoration]

I wonder why not clean off as much of the old grease and re-grease with new clean grease. And what I mean by clean is if the worm gear is damaged those pieces that have sheared off have to have gone somewhere. As a bicycle mechanic I always clean off all old grease and regrease when working on the moving parts of a bicycle . Also as the commentors below Josh Goldberg and Jeffery V pointed out, this video should have started with showing a bad gear and the running of the mixer with the bad gear so we can hear if the sound is similar to what we are experiencing. Other than that this is a very useful and well done video and I appreciate the demonstration.

[@stamekhad3637]

Thank you so much. Isaac from Israel

[@erwinhudelist4515]

Super - well done - I fixed my machine! Thank you

[@Peppermint1]

Trick: submerge overnight the entire gear assy into a bowl with paint thinner (acetone doesn't work). Next morning, remove and drop into another bowl with 99% Isopropyl alcohol. Let sit 1h, remove and let dry at air. Now you have a pristine assembly to work on. May want to do the same for the gearbox case. Remember to grease all shafts before placing back gears and inside the sleeve bearings.

[@Flasdingleray]

Thank you!

[@baldridgeroy]

I appreciate this video. Thank you.

[@darrylgordon2265]

Use the right size drift punch and the pin comes right out of the worm gear.

[@richreed2227]

This is an F'ing nightmare and I am pretty damn handy, the pin will not come out and have now buggered the entire hub and bent the shaft, do your self a favor and buy that small assembly, best spent 25.00 you will ever spend....

[@Nu11nV01D]

Bought the gear, couldn't get the pin out either (bent several punches) - currently buying the assembly. Still cheaper than a new mixer, though - should've taken it fully apart before buying the part. Ah well!

[@jtors5]

my gears seemed OK, but there was no pin inside with worm gear assembly. a badly bent was found inside, with almost an L shaped bend. Ever seen this before? Should I try to replace just the pin, or the whole gear assembly?

[@FixDotCom]

That pin definitely took a huge strain if it was bent. If the hole where the pin is elongated, replace the gear. If the hole is perfectly round and not damaged go for just the pin.

[@donaldhoover1254]

The grease is cheap, clean out the old grease and use new. The old stuff has pieces of the chewed up gear in it and will immediately start abrading the new gear, drastically shortening its life.

[@fuimas]

On minute 2:26 there is a pin being removed. No matter how hard I try, it seems to be stuck. Any tips?

[@FixDotCom]

That pin is normally very hard to remove. Use a large enough hammer and make sure the shaft is properly supported when striking the pin punch.

[@fuimas]

Thanks a lot. I´ll give ot another try and let you know how it went.

[@jviezel]

Definitely wear gloves and do this on a much larger (covered) work surface than the one pictured here. Another missing but absolutely critical step is to either thoroughly clean the old existing grease by removing any small rubber or metallic particles that may have broken off from the old gear or discard the old grease and use new grease (they sell 'food grade grease' that looks suitable). Any particles in the old grease will grind against the new one and ruin it very quickly.

[@JAMaxeRestoration]

Good point, I just typed out the same point before I read your comment, so I went back and added a reference to your comment.

[@AndrewEdmondson-g6l]

I've reassembled mine but cannot rotate the shaft using a drift through the hole in the end. Is that normal? I seem to remember being able to turn the shaft before dissassembly. I could just turn on the motor ...

[@AndrewEdmondson-g6l]

OK I switched it on and it worked. You cannot turn the mechanism using the shaft; too much gear resistance I suppose.

[@esteticacroc]

Thank's!

[@Mr2hami]

hi , tnx for the video , i have a probleme with my kitchenaid , samtimes start ,& others don't start , i think they have a securité stating, bad i dont know where ? !!!! help me please

[@Rickey904]

The brushes could be worn down.

[@michelevitarelli]

i am curious on why the nameplate is censored?!

[@rashidkhann73]

Sir fine work ever I saw A request to you repair a big dough machine gear assembly Thanks 🙏

[@montereycalifornia]

Perfect

[@jbbrwc]

I bought a new gear and when I took it all apart per the excellent video I found the pin holding the pinion gear to the shaft was missing allowing the gear to spin freely. I searched all thru the case and all the extra grease but never found it. I used a cotter pin instead and it seems to work fine. The mixer was given to us because it wouldn't work, maybe someone tried to fix it first

[@hollywilson8451]

I switched mine out but now it won't turn on. Any suggestions?

[@kimberlythompson2925]

I did everything and the when I plugged it in, a flash of smoke/light came out the back. What could’ve I have done wrong? I didn’t do anything to the electrical parts!!

[@aaronabner4317]

Our Kitchen Aid 600 series is set up a little different.

[@SurvivalReview]

That is not a ball peen hammer.

[@gwendolinesanderson8772]

CANT GET THE HOUSING OFF

[@baldridgeroy]

I would suggest wearing gloves. Just cut my finger cleaning that silver ring. Ouch.

[@flightTime123]

I can’t for the life of me get the pin out from the bottom cover

[@TheOneinthewoods]

Plastic worm gear buried in all that steel

[@nohaloli2651]

[@a1jsmiller]

Do you even know what a "ball peen" hammer is? You lost me at not knowing what tools you use.

[@caprarola26able]

Not good!
