    Is this a problem I can fix? Tried looking up the part through one of your links and it couldn't identify my specific mixer by model #. Your suggestions?

    I'll give this a try. I'm not sure it will take care of my problem!

I called KitchenAid about this issue with my mixer. The agent on the phone told me they are aware that it tends to happen to some mixers after they sit for some time. Basically, a "lifetime" of grease has been packed into the assembly and it is normal for it to release grease on occasion. I was told to run the mixer at 10 for at least 2 minutes to get it going and I should see a reduction in the oil leak. I had about a tablespoon worth of oil dripping down off the assembly. I was told that if over time it seemed to amount to about 1/4 cup then I should call to see about repairs due to a potentially bad seal. I was also told that the repair for that would most likely NOT cost the same as a new appliance.

This is the end seal of the motor, you can get parts from manufacturer. you will need a service manual, OR go to the manufacturers web site and contact them.

The oil leaks when the grease has broken down. One way to fix this is to take the mixer apart. Click on link to see how.

Clean the old grease out and google (KitchenAid mixer grease) and you'll find new grease on amazon for around $17.

Repack and it should be as good as new.

    If your model was not listed it was a farmed in model made by some importor. Best to purchase a better grade of mixer if you use yours quite often

SOURCE: Mixer leaking oil

I have the same problem. It is not oil, but the oil residue from the grease that surrounds the gear box. There is a very heavy grease that is wrapped around the gears. I am assuming that the leak is the broken down grease that seeped out from the gasket. Here is what I did: Remove the chrome ring(pound down on it gently, it will come off very easily) remove the pin on the shaft. Clean all the oil out of the assembly. Remove the motor cover. Remove all the screws from the large gear(about 5 of them)this will allow ou to pull the top of the mixer off. There are 2 screws holding the band around the mixer, remove them. There are 4 screws holding the top of the mixer to the bottom, remove them. You should be able to lift the top of the mixer off. Remove the black gasket, inspect it for cracks. I cleaned mine and put the same one back on. I thing all that was wrong was the screws were loose letting the grease leak out. It runs fine now. no leaks yet. You will find all the diagrams at this web site: http://www.appliancepartspros.com/partsearch/model.aspx?model_id=239812

SOURCE: My kitchenaid stand mixer is leaking oil

First off -- if it's still under warrantee, you'll want to go to kitchenaid.com and find the nearest service center. The next thing I say starts with "void the warrantee" steps. :)

It's very simple to open a stand mixer to see if you've got a simple problem or a bad one.

Unplug it.

Follow the aluminum "Kitchen Aid" band to the back of the unit, there's one main screw. Remove this, and set it aside with the band which should come right off at this point.

Now, there should be two screws on each side of the unit where the band used to be. Remove each of these. They're all identical, so no worries if you mix them up.

Now you can lift the top off of the unit and see inside. The motor is at the back of the unit, the gear box at the front is where the oil is coming from. Try (GENTLY) to tighten the screws that hold the gearbox together. With a little luck, the gearbox screws had come loose and it was oozing oil out through the seals. If they're all firm, then you've got more serious problems and you'll want to find a service center for it.

Good luck!

SOURCE: oil leaking from hobart d300 mixer

DEFINITELY contact the manufacturer (Hobart) on that one. Sounds like you're having some sort of an internal problem with it (something might be cracked), and in this situation, the best way to go is to contact the manufacturer rather than try to repair it yourself. If you're still under warranty, and you try to open the machine up to fix it yourself, you could wind up VOIDING the warranty, and if you're out of warranty, most repair places won't touch a machine that you've messed with already--too much of a liability.

Just give Hobart a call, and they should be able to help you (if you're in warranty, sometimes even for free!). Their phone number (according to their website, www.hobartcorp.com ) is 1-888-4HOBART (1-888-446-2278)


Good luck! :)

KitchenAid uses a grease in the transmission, and anything that may drip from the transmission will be very low in quantity.

If you want to disassemble, clean, and re-grease to remove the liquid part that has weeped out of the existing grease, do so with a food safe grease.

Mixer leaking oil is it possible some got into my cookie batter


It's pretty impossible to say for sure without having been there to witness it, but it seems possible that it happened. Some mechanical oils and greases are all-natural and wouldn't harm you if you ate a little of them, but that's not something that KitchenAid would ever tell you. As frustrating as it is, I for one would probably choose the safe route and make a new batch.

I'm having oil leak out of the top of the unit? It's still working all right though, what could cause that? I don't want oil going into the mixing bowl.


It can be that the lubrication oil that was meant for the gear drives loosened off and flowed out. You can use a good wipe of the excess that have flown out, wash off with light oil and clean dry on the drive.
Occasionally you can check this to repeat the oiling and dry wiping so as to keep the top mechanism lubricated without total drying.

Leaking oil


Leaking of oil in a stand mixer is not necessarily indicative of a large problem.

Kitchenaid stand mixers are overpacked with oil to last the lifetime of the motor. If the motor sits idle for some time (is not used), the oil may begin to drip from the gears and settle. Oil leakage may primarily be seen from around the beater shaft or planetary action.

A stand mixer can lose up to a 1/4 cup of oil before it needs to be serviced.

It is recommended to run the mixer on speed 10 for 2 minutes in order to redistribute oil back into the motor. In order to prevent future occurences, this is recommended to be done every 3 weeks if mixer is not being used.

KitchenAid 250 Watts; Classic: Leaking Oil


Found this,may be helpful.
Why do I see oil leaking from the beater shaft of my stand mixer?
Some KitchenAid® stand mixers that are not used very often or have been tipped may experience slight oil leakage from the shaft or hub attachment. To avoid the oil leakage, KitchenAid suggests that you run the mixer weekly for short periods of time. Generally, the mixer may lose approximately X cup of oil before repair is necessary. The oil used is FDA approved and is not harmful to consume, should any get into the food that you are preparing.

How do I add oil to my kitchenaid stand mixer?


if the oil is black or dark green this is the transmission grease. There is plenty in the case don't worry. You may have a cracked transmission case or a bad gassket. I think the most likely thing is a loose screw or two. Take the trim band off, 1 screw. Then take the 4 screws that hold the cover on. You can now lift the top and take a look for the sourse of the leak
