    ok. I LOOKED AROUND THE NET SOME MORE. FOUND THE MENDING SHED. USING THE MANUAL TOOK APART THE MIXER. THE WORM GEAR IS SHOT, SO I ORDERED THAT FOR $12. THE OIL LEAK WAS JUST MELTED GREASE, BUT THERE WAS STILL PLENTY OF GREASE IN THE GEAR BOX. LOOKS LIKE I'LL HAVE MY MIXER FIXED FOR ABOUT $20 ONCE I PAY SHIPPING ON THE PART!

Hi, SUSAN ? Sorry to hear about your mixer?s problems. You have a couple of issues that need to b be addressed. Your KA mixer?s internal gears are factory packed with enough grease to last a lifetime (whatever that means?). Depending on the age of your mixer and how long it's been idle and/or how heavily it?s been used; these factors will eventually cause the grease?s base oil to separate from its additives, with the resultant oil seeping from openings beyond the gasket and generally following the path of least resistance to an exit point, e.g.; the brush covers or motor air vent, particularly since it was resting on its side during moving. Gravity can be very insidious. Depending on how much oil was lost, it is possible that friction between the gears may cause overheating, so you probably should look at replacing the grease in the mixer?s transmission box. However there is a larger concern and that?s if the oil, in its quest to seep out of the mixer, found its way into the electric motor compartment and the motor components. The only way to check if that occurred is to actually take your machine apart and look inside. The inspection and troubleshooting of the inside of your mixer is a DITY (or you spouses) capability, particularly if your mixer is out of warranty. Just be sure to have the Parts List manual on hand. If you're lacking one, you can download a PDF version from the KA website. Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case, try KSM90P, and select one of the files listed under Parts List (check to see it this matches your mixer model). Turn to pages 4 & 5, titled ?Case, Gearing and Planetary Unit?, which provides and exploded view for the disassembly and reassembly of your mixer, along with all the parts. The transmission case gasket is Illus. # 18, which you might want to reorder for starters. Once apart you can check for any other unseemly wear and tear on the gears, etc. It can be messy but gratifying to fix your own mixer. As far as parts go, here are four potential KA parts vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com. Prices can vary widely between vendors for the same part so do some comparison shopping. Finally, here's a link to an excellent site that details the disassembly and replacement of a mixer's grease, which might be helpful, too. http://www.foodonthefood.com/food_on_the_food/2009/04/how-to-repair-a-kitchenaid-mixer-yourself.html You?ll also need to inspect your electric motor components to see if any of them have been contaminated with oil. On page 6 of the Parts list manual, titled ?Motor And Control Parts?, you want to carefully inspect all the components, particularly Items # 8, 28, and assembly 32, and anywhere else in the motor compartment that may have been contaminated with oil. Grease is good for lubricating gears, but bad for electric motors. Any parts exposed to oil will need to be degreased and dried before reassembly. I use GUNK degreaser and blow-dry the parts with a hair dryer or toaster oven (N.B. Be exteremly careful when doing this). If you feel this is beyond your capabities 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. I hope this helps. Howard, Burke, VA If this solution has helped you, please rate it, thanks! - hslincoln

How do I replace the oil that came out when the mixer was stored on its side?


Mary Ann,
There actually is not actual oil inside the mixer. There is however GREASE. When the grease gets old it can begin to separate and then leak out like oil. The grease needs to be replaced in the mixer. You can find online video's on how to that and where to get replacement grease.

Tip

My mixer is leaking oil.


This kind of unit are lubricated with grease paste. If the unit stays inactive for a long time, or if the motor and gears are overheating the grease paste gets melted into thin oil, and that will cause the leak.
The oil leak is usually coming from the gear box inside the appliance.
To fix the problem the unit must be taken apart, and cleaned. After this step, there is need to spread again the grease, using special foodsafe grease paste.
Disassemblying the gear box is not that easy, you will need previous experience and a gear puller to do the job properly and safely.
This appliances are also held with security screws to prevent the users from taking apart the unit, and can only be disassembled using a Security screwdriver tip.

The grease can be purchased here, check at the bottom of the page: Kenwood chef food mixer Grease.

Mixer was laid on side for travel and it appeared that a small amount of 'oil' was found on outside of head. Can oil leak out of head? Is the oil refillable?


Hi FDLISS, sorry to hear about your mixer’s ‘leaking’ issues. KA mixers should never be placed on their sides, or you see what can happen. So how bad is this oil leak problem and what can you do to fix it?
First, if the amount of oil you found leaking was small and if your mixer otherwise works normally with the missing oil you really don’t need to take your mixer apart to refill it. The good news though, is that you can take the mixer apart and refill the grease, if you feel it is necessary.
The internal gears are factory packed with enough grease to last a 'lifetime', whatever that means? Depending on the age of your mixer, where it’s been stored, degree and intensity of usage; all these factors contribute to cause the oil to come out of suspension and seep to the bottom of the transmission box. When you laid your mixer on its side, the oil flowed to the lowest point and found a way out. Gravity is very insidious.
What should you do? Clean your mixer head where the oil came out with a sponge and hot, soapy water (DO NOT immerse your mixer in a sink of hot soapy water, though!) Hopefully it did not come out of your electric motor brush ports (those ‘screw’ heads on each side of your mixer head.)
The inspection and troubleshooting of the inside of your mixer is a DITY capability, particularly if your mixer is out of warranty. Just be sure to have the Parts List manual on hand. If you're lacking one, you can download a PDF version from the KA website at: http://www.kitchenaid.com/flash.cmd?/#/page/home. Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case use KSM50P, and select the file that matches your mixer under Parts List (4) from the three versions listed.
Turn to pages 4 & 5 for the disassembly and reassembly of your mixer, along with all the parts. It can be messy but gratifying. You might want to reorder the gasket and an ‘O’-ring for starters. Once apart you can check for any other unseemly wear and tear on the gears, etc.
If you think you need to replenish the grease in your transmission, you should use a food-grade grease that you can order online (although I’ve seen automotive bearing grease used too – your call).
Here are five potential vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com; and Grainger.com (for grease). You should search for ‘food grade grease’ online (although I’ve seen automotive bearing grease used too – your call). Prices can vary widely between vendors, so do some comparison shopping.
Here are links to three excellent websites that detail the disassembling/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, regrease and reassemble your mixer.
Finally, 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.

When my 85 year old mother, who no longer does much cooking or baking, heard that my trusty KitchenAid stand mixer finally gave up the ghost after 25 years of great service, she sent me her KitchenAid...


The mixer normally has it's gearbox packed with (quite thick) grease. Over time it can heat up and become more fluid and leak out. I would guess that the amount of oil you saw would not be a problem to loose. If it were mine, I would use it and not worry. If you do feel you need to check, the grease is packed in the front of the head. You will need to remove the head, split it (you will need to remove the band and planetary) and then you can see the gears.

KitchenAid wobbles when mixing


Do not store or transport the mixer on its side ever. Always upright. The grease in the gearbox should even out eventually. Try sitting on it when it wobbles. At least yours works.

KitchenAid wobbles when mixing


The "wobbling" sounds like an issue of beater to bowl adjustment, which can come out of alignment naturally over time and with use of the machine.

If the flat beater is striking the bottom of your bowl, this may cause the locking mechanism to loosen and may cause the mixing head to "bounce" during use.

Your Use and Care Guide will cover the "beater to bowl adjustment," which you can do at home in a few minutes with a flathead screwdriver.

Also, 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.
