Cuisinart mixer leaking oil...Still on warranty

The shaft of the beater is bent. After frustrating discussions with Cuisinart customer service, I was able to free my shaft. First, you will notice that the beater screws onto the shaft. Unscrew it. Then, take the nut off the shaft. Next, put a wrench on the shaft that is only slightly larger than the shaft, followed by a washer. Next, screw the nut back onto the shaft. Finally, holding the wrench at the end, hit the wrench close to the shaft with a hammer. If the shaft doesn't come out, hit harder. Since the shaft is bent, you'll need to purchase a new beater.

Cuisinart hand mixers are not repairable. You can buy replacement accessories like beaters, but you can't buy any internal replacement parts.

I have a Cuisinart HM-70 and I stripped the plastic gears inside by trying to mix a really thick dough. It was easy to open and get to the plastic gears. When I called Cuisinart to try to get replacement gears, they said that they don't sell replacement parts and their hand mixers are not repairable. I looked all over the internet and no one sells internal parts.

Unless your mixer is still under warranty, I believe that you're out of luck and your mixer is headed to the electronics recycle pile.

Most handmixers today are sold with plastic gears - including high end brands like Viking. For me the lesson learned is to buy low end hand mixers (don't buy a top of the line 9 speed mixer) and treat them like they're disposable when they break.

eaking 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.

If you still feel as though the mixer is in need of service, you may locate Kitchenaid certified repair centers through the following link: http://caservice.kitchenaid.com/

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.

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.

Exploded parts views for all mixers are available at www.kithchenaid.com. Click "Customer Care" in the upper right hand corner of the main page, and then select "Locate Manuals and Guides." You will need to enter the unit's model number exactly as it appears on the bottom of the mixer. It will be listed on a white sticker.

Ah, I found the solution.
