Question about KitchenAid K45SS Classic Stand Mixer
My mixer is about 15 years old works well except it growls at slow speed
Hi BCPSBT. You say your mixer growls at slow speed. It could be that it’s time for an oil (lubrication)
change. KA packs your mixer’s
transmission with enough grease to ‘last a lifetime’, but depending on the age
(in this case a middle-age appliance) and usage (you don’t indicate) of your
mixer the grease breaks down into its constituent parts: oil and additives. Over time, the additives will thicken and provide
less lubrication to the transmission gears and this is probably what is
If you are DITY type person, feel adventurous, and your mixer is not under warranty you can troubleshoot it yourself. Be sure you have the Parts List manual on hand. If you are lacking one, you can download it from the KA website http://www.kitchenaid.com/flash.cmd?/#/page/home.
Click on Customer Care>Locate Manuals & Guides> and select “Consumer” for User Type, then 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 model.
Turn to pages 4 & 5 for the disassembly and reassembly of your mixer, along with all the parts. For starters, you should consider reordering the gasket (Illus. No 19) and O-ring (Illus. No 34). With the mixer apart and transmission exposed, you should be able to confirm how well the lubrication grease is distributed and doing its job. Also, once apart you can check for any other unseemly wear and tear on the gears, including the planetary and agitator shaft gears.
When you re-grease the gears and assemblies, you should use a food-grade grease that you can order online (although I’ve seen automotive bearing grease used too – your call).
As far as parts go, here are five potential online vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com and Grainger.com (for grease). Prices can vary widely between vendors, so do some comparison shopping.
Finally, here are some links to several excellent websites that detail the disassembling/reassembly of a KA Mixer.
Good luck and have fun. I hope this helps. Howard, Burke, VA
