Question about Food Mixers
Hi, MARITZALEW. You don’t indicate your specific KA mixer model, which limits the quality of the solution(s) I can offer, so I’ll start with a general solution. From the symptoms you describe, it appears that either 1) the agitator shaft (what you attach the beater blades to) is dropping out of the planetary, or 2) the whole planetary assembly is dropping from the mixer head.
The bad sound you hear when you attempt to push the assembly back into place is the gears protesting because the mixer is not operating normally. Continued operation in this manner could further harm the internal transmission gears, if not already damaged.
In either case, one of the retaining pins has probably failed and needs to be replaced. This is a job you can perform yourself, but it will be a little messy but very gratifying.
Do you have your mixer’s Parts List manual on hand? . If you're lacking one, you can download it from the KA website at: (http://www.kitchenaid.com/flash.cmd?/#/page/home).
Click on Customer Care>Locate Manuals & Guides> and enter the 6 character model number and select a file under the Parts List. (Check to see it this matches your mixer model). Turn to the pages titled: Case, Gearing and Planetary Unit, which provides an exploded view for the disassembly and reassembly of your mixer, along with all the parts.
Locate the Groove Pin on the parts list and then see where it is show on the exploded view. This pin retains the planetary/agitator shaft to the mixer head, and I suspect this is the pin that has failed and needs to be replaced. There is a similar pin which holds the agitator shaft inside the planetary. Getting to either pin will require the disassembly of the whole transmission. This will be messy as you will need to remove all the grease from the gears and center shaft.
Also, while your mixer’s apart you should check for any other unseemly wear and tear on the gears, etc. You may find more things that need replacement than just the groove pin.
Besides needing a replacement pin(s), grease, and possibly a gear or more, you might consider replacing the gasket, too. I recommend using 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. You should be search for ‘food grade grease’ if you start digging into the transmission. Prices can vary widely between vendors, so do your comparison shopping.
Finally, here are some links to several excellent websites that detail the disassembling/reassembly of a KA Mixer. The mixers may or may not be similar to your mixer, but the principles are the same.
If you feel troubleshooting and repairing is beyond your capability, then I would seek out a local small appliance repair shop in your area. KA Customer Care can give you names of local KA authorized repair shops in your area, but you can also do an online search to supplement what KA may provide you. Call to explain your circumstances and find out their hourly rate and get an estimate of what they think it would cost to repair your mixer. Also, always obtain three or more estimates – do some comparison shopping.
Good luck and have fun. I hope this helps. Howard, Burke, VA
