Droopy head on Kitchaid Stand mixer - KitchenAid KSM150PS Artisan Series Stand Mixer

SOURCE: Question regarding KitchAid mixer, Model K45ss. excessive noise.

Maeveda, Congratulations on your 30 year old KA mixer! Was it a wedding present? Do you still have the K45SS Parts List? If not, 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, use K45SSW select Parts List (1) and then check to see it this matches your mixer). You can check on page 4 & 5 for the disassembly and reassembly of your mixer, along with all the parts. It will be messy but gratifying. Once apart you can check for any other unseemly wear and tear on the gears, etc.
As far as parts go, here are four potential vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com (this vendor the best prices for my wife mixer's parts, but sadly they had to back order them, which was disappointing to SWMBO). Prices for the same part vary widely between vendors, so do your comparison shopping. Here's a link to a 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
Good luck and have fun. I hope this helps. Howard, Burke, VA

referring to:

You can see that there are 5 screws holding the upper and lower gearcase together. They pinch the gasket number 26 together and prevent the oil and grease from leaking. Remove the chrome ring by prying gently around the ring. You will see the 5 screw heads. Tighten them and the leaking will stop.

If it still leaks then you may have to replace the fiber washers number 29 which will involve disassembling the lower gear case.
