When you remove and replace the gear worm take special notice how the bearings are situated. The flat side should be facing the side not the top. I noticed I had mine in the wrong way and had to fix it.
I was just going to say...at 12:20 it looks like the front bushing is turned 90° from where it should be.
I recommend pinning this comment so that it will be at the top and everyone will be sure to see it.
The special pliers are called "snap ring pliers". Regardless of what kitchenaid calls the "gear worm", those are more commonly referred to as a worm gear
Thank you for your video! My 12 year-old Kitchenaid Professional HD mixer (KG25H7X) was leaking "what seemed to be" oil - - which was actually a bit of breakdown of the lubricating food-grade grease originally applied by the manufacturer. Equipped with a Robertson screwdriver (square tip), snap-ring pliers, a few wood coffee-stirrers (popsicle sticks), a few shop towels and nitrile gloves. I followed your instructions to open-up the mixer, take the mother-board out of the way, remove the parts, clean them, apply new food-grade grease and put everything back together. While at it, I also replaced the gasket. Even though my mixer does not have a lot of wear, I was pleased to notice that the gears were all in top shape! By the way, the gasket part # is WP9709511, it is listed in some places as Whirlpool Genuine OEM WP9709511 Stand Mixer Transmission Case Gasket and in other places as Kitchen Aid Stand Mixer Transmission Case Gasket. All in all, I am truly happy to have done this by myself. Thank you "2 Guys & A Cooler !!!! (Christine - - Québec, Canada - - 2020-07-18)
Wow, this video is so great! I had sent my mixer to KA for a factory repair and it didn't come back perfect. Turns out there were two other gears that needed to be replaced but I limped along with it long enough that I couldn't really send it back expecting them to take care of it so I tackled it myself. Thanks so so much! It's purring like a kitten now, not clunking along like an old beater any longer!
This worked perfectly to fix my Kitchenaid Professional stand mixer. Had to find parts from a different site for my model #, but worked great. Saved me tons of money as KitchenAid wanted over $200 to repair. I spent just $45! Thank you!!!
That's awesome!! You are most welcome
I can say this is the best KitchenAid mixer repair video, not one of the best ones...thanks Eric!
You are welcome. I'm glad it helped!!
Thank you just changed my mixer’s gear and other parts , which I had been using for 15 years and I mean using everyday,with your help I bought the parts from KitchenAid will try to see if their part last longer.
But thanks again Very calm and detailed instructions
Fantastic step by step. just popped mine open and followed along and I'm back in business. thank you for sharing!
Yess! Omg ! Now that its pandemic, there’s no way I can get a new mixer like KA again, mine was broken too same problem “gear” now that we watched this video my husband can fix it at home no need to spend lots thousands here in the philippines... parts we need as we checked in the market has reasonable price. So we can diy. Thanks a lot for this video... wish we saw this from last year so I dont need to manually need doughs!🙋🏻♀️🙋🏻♀️godbless! Stay safe everyone!
Thank you thank you thank you! I paid over $200 to get mine fixed 2 years running and I refused to do it again and thank goodness I did! Parts are ordered and I'm doing it myself!
Excellent! That's incredible!! Let me know if you run into any issues..
Thanks so much, I use my mixer often for bread mostly. I’m so happy it can be fixed.
You are very welcome..
Hello, Eric, Finally I replaced the worn gears following your suggestions and the machine seemed to work fine but there was some annoying clatter sound. Then I replaced the worm gear as well (though it is not worn visually at all) and now the machine runs great!
OH That's awesome. I'm just getting around to answering comments and I saw the video you sent me. I'm glad you got it figured out. I was thinking it was a gear issue as well....
If I only had this video one year back. Thank you guys so much. :)
Oh No!! LOL. Hope you don't need to fix it for a while!!
Thanks for this video, the clip that needs the "reverse pliers" had me stumped.
Thanks for the video..it was great help replacing worm gear for my Kitchenaid professional plus 5.
the instructor did a good job
Great video, thanks for sharing! It looks like your main vertical shaft is bent (I could see a wobble when you spun it by hand and when the mixer was running at the end). This could be adding additional strain to the gear, causing it to wear out faster. You may want to consider replacing it.
Great video and extremely helpful.
Thanks for the video! Just repaired this model a friend messed up. Hopefully, I get to keep it.
Thanks man...this was helpful. I believe having that ring split pliers is a must.
Great video with helpful links. Thank you!
Thank you for watching and really appreciate the feedback.
Very helpful. This was the same process I followed for my artisan 400 with the key difference being that the flat sides of the worm gear axle are positioned on the sides and not the top and bottom. Thanks for the video.
Nice. Once it's all opened up the mechanics are fairly simple. Glad it's easy to fix!! Thanks for watching.
@@2guysandacooler I opened it. To my surprise every thing looked good, gear teeth all fine. But when rotated food processor larger wheel, which inturn needs to move the small wheel. Didn't move, after removing three screws, I noticed a small pin had come off which keeps top wheel and bottom small aligned together. Pin was bent, is that how it is supposed to be. I put the bin back, vola it start to spin.
Next question, can I use white grease?
@@2guysandacooler linksharing.samsungcloud.com/wwLRXn56vwls
This is the picture of the gear assembly I was talking about. After putting the pin both wheels are moving. I only fear what if the pin comes out again? Its slightly bent
Please keep in mind mine is a different model. Gears are standing up position.
@@jackryder6732 nice!! The innis suppose to be straight. You can use white grease.
Great video. Well done. Thank you for the clear instructions!
You are welcome.
Thank you very much for spending the time to put this video together! I’m now totally prepared to fix my own. Cheers
Hey Dustin, thanks for the message. Glad to hear that you're about to fix your own machine. Talk about save some $$.
I'm glad I found this video o was about to send my 600 to be repaired but instead I'm ordering parts tonight thanks for the info
Nice!! Let me know how it turns out....
Is the 600 the same part number as the 550?
@@sethzelenik1605 I ordered mine off Amazon I just typed in my mixer style and found what I needed.
@@2guysandacooler everything works great
@@davidstreet1628 thanks. I ordered mine off Amazon today. Hope it fits. I'm sure it's the same. Thanks for the reply!
Excellent video. Exactly what I was looking for and ordering parts now👍🏻😎
Took the worry away to watch your video. parts on order! :)
Excellent. Thanks for your comment. Congrats in advance for fixing your machine.. let me know how it turns out...
Links are out of date, but yeah, this is an easy repair. Great video.
I found parts at Genuine Replacement Parts, Kitchen Aid KF26M2XPM5 Follower Gear, $19.89 and $8.88 shipping. I bought two gears so I have a spare. Fast UPS shipping. Bagels this weekend! we're back in business.
Hi. The special tool is called snap retaining ring pliers. Only about 4 to 10 dollars from different stores. Great investment as those rings are located on everything.
I really enjoyed your video. Our 500 Plus gearing still looks good after taking a look and redistributing the grease back towards the gears. We make dough and other heavy products in the 5.5 qt bowl, and IMO overloading the mixer is the problem. Reduce the recipe and do not overload the mixer to have years of good service. Otherwise I would recommend a Hobart commercial mixer.
how did you get the top off of the 500? There are no screws on the sides underneath the metal band.
Thanks my job said this unit didn't work they purchased another one gifted me this one I know now what the problem is, I also have the Kitchenaid heavy duty that has the same problem and is 19 years old both will be operating really soon thanks again
NICE! That's awesome when things like that happen!!
Great video! Thanks for the help.
Thanks.. Appreciate the comment...
Good video thanks for posting!
Excellent. Thanks for your comment...
I’ve got one of these in my shop and the folks tried replacing the gear but they didn’t clean the case of the old contaminated grease and the metal fragments in the old grease caused the unit to sound like it was going to destroy itself, luckily it wasn’t run long. Not having the upper bearing in place also didn’t help either.
well done explained everything
Brand new gears bro.
Sorry, you only mentioned changing the motor and the board... Not sure what to tell you. A grinding sound is the gears not lining up properly. Perhaps tour main rod is slightly bent or the company you bought gears from might not be OEM. Maybe you have the wrong model gear. You should remove the gears and run the unit just to see if there's any weird wobble or noise that comes from it being turned on.. Hope that helps,
Loved this video -- except the "gear worm flat notches facing up" 11:50-- this caused problems when I turned on the motor, and the housing wouldn't close tight... It wasn't until I watched a different video that they said the rounded part, flange, sticks up. So thankful! I couldn't figure out what the problem was. It's all good now. Why the discrepancy here?
Thanks for the comment. I'll have to open mine up and see how it's arranged. Glad you got yours fixed though!! If I was incorrect with the info I'll have to find a way to fix it. Thanks for bringing that to my attention...
@@2guysandacooler Thank you for responding. Your instruction seemed to be right and this adds to why this is so perplexing! Could it be a different model situation? Take care and hope we can get the answer!
Very good instructional video, thanks! Subscribed to your channel. Replaced the two main gears and got it all back together. It works fine now but seems to be louder than before. Read all the comments below and nothing seems to address it. No knocking, clunking or anything unusual, just louder than before. Any thoughts on why?
The retaining pliers linked in the description are not going to work. The tips are too big to fit in the holes in the retaining ring. I tried grinding them down but they just kept slipping. I got channel lock’s 927 8 inch retaining ring pliers. The looked a lot more like the ones used in the video. Only other issue was the shaft was much harder to remove and I had to use hammer to get the new gear on. But this is the first time I’ve changed any gears on it.
Other wise awesome video. I was able to follow it and fix my machine. Thanks
Thanks for the comment. I just updated the links.
great video, thank you!
Your welcome. Thanks for watching...
Thanks for your video. I have the Professional 5 Plus. The circular piece that holds the dough hook and paddle is falling off which does not allow them to move. I don't see how it stays on. Do I need to replace the shaft? Thanks for your response.
Thank you Sir. Good video. However, I put my parts back, I only hear the gear is spinning. The main axis is not propelled. I haven't figure out where the propelling force is from? Friction?
Thank you so much!
Thank you for the detailed video.. Can you please share from where you bought the gears. Thanks in advance!
thank a lot , bravo
Just happy I found my kitchenaid model. I have a problem finding replacement for the power cord part no. W10132081 since its old. What part no. can take its place?
I have an extra piece that I don't find in the video nor in the diagram... A ring about 1'' long that fits the shaft. I don't remember where it was. Any idea?
I actually fixed the bras worm follower gear as described in your video, it worked great... And 2 weeks later the gear hub worn out. I still don't understand why, I was making bread dough. Anyway, it could be because if this piece I put back on top of the retaining clip.
Eric, great video. Big Question... I have ordered all of the replacement gears from your links, Thank you! Problem: I cannot get my Shaft to drop down to remove the brass worm gear 😵💫, any tips? It does not want to drop down, nor can Iift the gear off the shaft!?
The vertical shaft seems to be bent. It does not stay on axis as it rotates
Very helpful, thanks. What kind of grease did you use?
food grade gear grease
I wonder if I could do the same with my Pro 600 and even my 4.5. qt Deluxe? 🤔
Thanks for the video. Great machine, it only needs some gears changed every year though? Hmmm. I regret getting one. Is there really one of these mixers that doesn't need yearly rebuilding?
Hey Greg. Most people won't have this issue. We use our machine commercially so we put extra wear and tear on it.. We've had ours for 10 years and it's still working strong...
Eric, Great video. I have a KA pro 5 plus. that looks just like yours in the video. The bottom of the motor housing is moving on the pedestal. I'm assuming the screws that hold the housing have loosened up. My question is do I have to remove the entire motor to tighten the screws. I would have to remove the transmission housing also which would allow me to replace the gear anyway. Just asking your thoughts.
What grease did u used?
Just subscribed your channel
Thank you very much..
Great video, thanks. My 500 series just started slipping. Was thinking of replacing all gears rather than opening and inspecting (since I'm not quite positive I can tell what's good or bad). Would you recommend a different approach?
Hi, I replaced this gear as it was stripped but now the mixer squeal at high speeds. What could the issue be as I have checked it over multiple times.
Very high-quality video, thanks. Tell me, what brand of grease do you recommend for the gearbox? And how often to change it?
Any high temp food grade grease will work. I think I have a link the description box as well. I don't change it very often. Usually only when I'm fixing the gears.
They’re called snap ring pliers
Hello, if you do not first identify the origin of the problem (lower levels). To observe the very important play of it at the level of the plunging axis and support of accessories, "WHAT WOULD SEEM EXCEPTIONALLY NORMAL".
It is certain that your problem will resurface even faster than the first time. Good luck and thank you for this video. FALCO
I changed the motor & Board for my Professional 550 HD Mixer. Why it is there is a grinding sound when I mix 700g flour?
If you hear grinding then that means it's a gear issue.. You most likely need to change the follower or the worm gear (the main 2 that operate the unit)
Very good video. Thank you. Can you please send me the link for me to buy those parts you have? 😊🙏
They should be in the description box 😁
I have the exact problem you describe, but I can't find a place to buy the 2 gears. Can you please tell me where you purchased them from? Thanks. Mike
Hey Mike. Take a look under the machine and let me know the model number. I'll point you in the right direction 😉
Exelent !!
Is this gear worm okay to use in pro 6qt mixer ?
ThankYou!
You are welcome. I hope this helps....
Are these parts the same for the 600 as it is for the 550?
Im not sure. Click this link and type your serial number in the space provided. It should give you the parts that you need to order. www.ereplacementparts.com/kitchenaid-parts-c-114958.html?osCsid=k2j237eeeh79kk0lticefht1d0
How to order that gear? My mixer same as that you repaired it goes down the connection of whisk every time i do mixer but when i push up it wiil okay again what maybe the problem? Is there any parts to change? Thank you in advance 😊
Can you explain the problem again. I didn't understand in your original comment.
I followed the steps but the machine was very loud. I took it apart and tried again. This time it is a little quiter but I hear a clicking sound. Any idea what I am doing wrong? I believe I might not be putting the worm gear back corrsctly but I am ensuring that the flat ends are up.
Hi Tam, It really hard to trouble shoot without looking at it but my guess is that if you hear clicking it's because the main gear (the long one) might be placed incorrectly. It may be loose or therefore its not fitting just perfectly in the space provided... If the other gears are on the rod and the pin has been put back in place to hold everything together then you will want to focus on the gear worm. This is the gear that has the ball bearing rings on either end. Sometimes its tricky to get on just right but look at the video again and check out the position of the brackets. Hope that helps. I cant wait to hear about how you have fixed your machine.
It seems like there is too much wiggle room where the worm gear fits into the housing in my unit. This causes the gears to slip and strip out far too quickly. I just replaced gears and they are already slipping when my wife is making her bread dough. Has anyone else noticed this? I’m thinking about modifying the housing to hold the gear in place better. Not sure how yet. Might superglue a thin piece of metal in there.
Great video, but I don’t have that tool you mentioned. My kitchenaid rotation part fell down while I was using it. I bought mine second hand :0( I had no idea it came damaged. I think is missing that little pin you put the very first time after you cleaned it up and started putting it back together. What brand oil you used? I’m so nervous to do it but I want to use my lovely kitchenaid.
Hi Laura. I think you are absolutely right. That little pin holds everything in place while it's spinning. Should be an easy part to get. Here is where I but my replacement parts for my kitchenaid. www.ereplacementparts.com/shear-pin-retaining-pin-p-621981.html Be sure to check the model number on your unit to see if this part will work.. The little tool I have is this one: amzn.to/2NxWkDi it comes in real handy when removing those rings that secure the rod and the grease that I use is this amzn.to/2wtSHaT but you could use any food grade grease.
It's a very easy machine to repair. If you have any questions you can always reach out..
Thank you very much
Good job.

+I changed the brass gear and packed the housing with grease...getting some noises but machine seems to work..any ideas?
I cannot get the bottom gear on the shaft off I have an older professional 6
I bought the machine in January 2020 and have used for about 4 months & today it has stop spinning do you think I need to change the worm gear ?
Does it make any sound when you turn it on? Like a grinding sound or does it sound normal it just isn't spinning?
Hi! I've followed your instructions to a T, and afterwards the mixer functions as you would expect, but is accompanied by a clinking noise. Any ideas on what I should check?
Me too!!
@@jennasotomayor4310 6 months later and I've not figured it out. I've replaced many bits, and I am currently about to put a new motor in.
I suspect that the issue is a bent planetary shaft. Let me know if you manage to figure yours out.
@@EliPutney I’ve just been replacing parts until hopefully it stops lol. One thing that makes me think the planetary shaft is bent: in the video, it slides off pretty easy. On mine, I had to whack it with a rubber mallet A LOT to get it off.
I have the same Professional 550 plus Model KV25MEXCU5 serial W22964476 and the speed control is hard to move - do you know what part I would need to fix (if this is easy to do)?
Thanks very much for the video! When you mentioned stripping the circlip while using pliers what did you mean? I removed the clip with pliers and it got slightly bent but I think it should still work. It seems like it should still be fine. Do you have any advice on what to look for in a damaged clip?
When I removed my clip with regular pliers I opened it up too much. I could never get it back to having a tight fit. If yours goes on tight then I think it'll be good to go.
@@2guysandacooler Thanks for the reply! I got it all back together but now it makes a really loud clicking without being under any load. Does that seem like a problem with the worm gear itself?
I have spar spiral mixer 60 qt liter it is trouble in third gear I need help to rectify this I think third gear wheel problem how we open this model gearbox
What would cause this machine to Bog down when mixing dough? Only 1.5lb dough
sometimes the dough is very stiff (like for bagels or pretzels) and it really puts a strain on the gears when there's too much in there.
Bonjour, si vous ne n'identifiez pas d’abord l'origine du problème (les paliers inférieurs). à en observer le jeu très important au niveau de l'axe plongeant deu support d'accessoires, "CE QUI SEMBLERAIT EXCEPTIONNELLEMENT NORMAL" .
Il est certain que votre problème resurgira encore plus rapidement que la première fois. Bonne continuation et merci pour cette vidéo. FALCO
Our Kitchenaid professional was making noise. I took it apart and the gears look good to me. How can you tell when it is worn out?
That's a great question. Generally the teeth will not have sharp edges and you will see the center start to wear out. The symptom of gears getting worn out will be signs of skipping. If it's making lots of noise maybe it just needs a good cleaning... Remove all the grease and replace with new grease...
@@2guysandacooler I think the motor itself needs lubrication. Is there a hole to oil it with liquid oil?
You know, I' don't know. I've never had to fix that part...

Hello , my 550 HD mixer attachment hub does not spinning. What is the problem possible? Thanks.
The gear worm probably needs to be replaced
@@2guysandacooler I can mix dough, but can not use attachment part, the attachment hub does not spin.
What is the best way to clean the grease out of the mixer.
Great question. I'm not sure about the best way because I haven't been able to do it with out it getting messy but I put some gloves on and remove all the gears. I then scoop out the grease with my hands (gloves on) and detail the housing with a q-tip and some paper towels. I'm sure you can use a can of solvent to really get it perfect but I've never needed to go down that road..
How much grease does it take to fill the assembly? Thx
not much. About 1/4 cup +/-
Which tool did you use to remove the clip? please name that tool and where can I buy parts in Canada

Hii
I have a question
I have kitchenaid stand mixer
Recently when i use it melted plastic smell with white smoke coming out from the speed plate i just stopped it and wait like 5 hours and try to work it and its work but the sound is a little weird
Now when i try to use it in dough i feel that its work hardly and the smell getting out from the attachment place its not working like before
What's the problem?
Hello Lena, Not sure. It might be a motor issue. All the gears are made out of some sort of metal so you generally won't have any smoke coming from the gears but the motor if it starts to overhear and burn up might give you some smoke and melted plastic smell. just a thought.
Thanks for replying
You know what ... I use it many times after that happens and it's still working but the sound comes while working is not like before
Do you think I have to change the gear ?
If its motor issue its gonna work ?
There is a used one for sale near where I live,......are those good or I should look for something else ?...tx
I would (depending on the price). This is a great machine..
@@2guysandacooler Thank you !!
I just purchased an Ankarsrum mixer, Swedish made and costly. I much prefer using quality made equipment than products made by greedy manufacturers who plan obsolescence and invest more in marketing than quality.
I only used my kitchen aid about five times. How do I know if it's the gear. It's not starting . It's just dead. I tried plugging it into different outlets to no avail.
That's a tough issue. If the unit isn't getting power it could be that the chip panel that controls the switches may be damaged, the gears have seized, or the motor could be burned out. Hard to say... I hope you can figure it out..
@@2guysandacooler 👍

It looks like your gears are very stripped. Take your machine apart like I did in this video and replace the main gears. The main 2 gears. Here is a place to check your model number and see what parts you need. www.ereplacementparts.com/kitchenaid-kv25mexer5-empirered-and-stand-mixer-parts-c-114958_114959_290204.html
where you buy the greace ?
I got mine here: amzn.to/2wtSHaT
Both the old and new worm follower I got are extremely difficult to get on and off the worm gear. Am I missing a step?
I don't think so. Just make sure you place the worm follower all the way down the shaft till the small hole is exposed. Then Place your pin back in the hole. Replace the gear that goes on top of the worm follower by lining it up correctly and finally your worm gear should be put back. Be sure to watch the video again as that particular gear ha to go in a certain way otherwise it doesn't fit perfectly. It should be a perfect fit once you are all done
I got it! Thanks!
Shelly Gray awesome!!! Great to hear.
My gears are not coming off that easily.. i’m banging them up with a screwdriver and hammer and still not budging
