Strain relief bushing kitchenaid classic mixer

SOURCE: 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.

SOURCE: My wife's kitchenaid classic 250 watt mixer wobbles on the base

It sounds like your mixer likes to take a beating, ive never dropped one and for good reason, they weigh quite a bit. first check to see if all the rubber legs on the bottom are still there. if they are the only possible solution to fix it after being bent or warped is to either re-shape the part using a tool strong enough to do the job, or to replace the parts needed. the hinge pin part number is 16910. is the base is bent the part number is 240151-1. If the lower portion of the mixer itself is bent or warped this is a serious problem and will require you to dissassemble the entire unit. part number for the lower gearcase is 240350-4 Please not that all the parts list are white in colour. hope this helps.

Thanks

SOURCE: Broken attachment knob on brand new Kitchenaid Mixer

Hi LPAYNE724, If you have all the pieces of plastic, you might try ‘super’ gluing them back together around the screw, but you might be better off purchasing a completely new knob.
You say the mixer is brand new. Is it still under warranty? If so I’d contact the KA immediately and tell them about your problem with the stir speed not working. The KA website is at: http://www.kitchenaid.com/flash.cmd?/#/page/home. Click on Customer Care>Contact Us> and the toll free phone number is listed to speak with someone. You can also look under the Warranty & Service Plans to see what KA will do for you. I've extracted parts of it here:
Hassle-Free Replacement Warranty
We’re so confident the quality of our products meets the exacting standards of KitchenAid that, if your mixer should fail within the first year of ownership, KitchenAid will arrange to deliver an identical or comparable replacement to your door free of charge and arrange to have your “failed” mixer returned to us. Your replacement unit will also be covered by our one year full warranty. Please follow these instructions to receive this quality service.
If you reside in the United States and your KitchenAid® mixer should fail within the first year of ownership, simply call our toll-free Customer Satisfaction Center at 1-800-541-6390, 8 a.m. to 8 p.m., Monday through Friday, 10 a.m. to 5 p.m., Saturday, Eastern Time. Give the consultant your complete shipping address. (No P.O. Box Numbers, please.) When you receive your replacement mixer, use the carton and packing materials to pack-up your “failed” mixer. In the carton, include your name and address on a sheet of paper along with a copy of the proof of purchase (register receipt, credit card charge slip, etc.).
If, for some reason KA won’t honor the warranty, you can still purchase a replacement knob, 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: http://www.kitchenaid.com/flash.cmd?/#/page/home.
Click on Customer Care>Locate Manuals & Guides> enter the visitor type “Consumer” and then Enter the 6 character model number, in your case: KP26M1, and select one of the first two files listed under Parts List (47) (The first file, KP26M1XAZ4.pdf (304.18 KB), is for a -4 series model and the second file, KP26M1XAZ5.pdf (724.41 KB) is for a -5 series with slightly different insides, so make sure you have the correct Parts List manual.)
For a series -4 mixer, turn to pgs. 4 & 4, titled Case, Gearing And Planetary Unit that shows an exploded view for the disassembly and reassembly of your mixer, along with all the parts. Locate Illus. No. 4, Thumb Screw. (For a series -5 mixer, turn to Pgs 4 & 5, and locate Illus. No. 23, Thumb Screw). You’ll want either the black or grey Thumb Screw. The parts are the same for both series mixers, so take your pick.
Here are five potential online 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.
Good luck. I hope this helps. Howard, Burke, VA

SOURCE: cannot get drip cup back

I had a major problem with this beauty ring for an hour too, my issue was I could get it on but it would not stay, there was grease and it was slightly odd. I bashed it, tried to stretch it, tried to bend in the top a little.

The only solution I saw was the fact there were dots of where super glue was applied, and then I thought to myself, that they had glued it. I added dots of super glue and slid it on, held for a few seconds and let the glue do its magic. I think either it had been serviced and glued before, or it just was too out of shape to click back in.

I have seen some videos of people sliding it back on tension wise, but a few drips of super glue (front back and sides) allow you to break it loose again if need be but it wont let go on you. This is obviously only going to work if you can get it flush in the first place.
