Tip & How-To about Food Mixers
If your KichenAid mixer doesn't seem to have the power it once had try the following repair procedure.
More than likely the armature needs to be cleaned if you have made sure that the brushes are OK. The brushes are acceptable if they have 1/4 inch of carbon left. Disassembly of the unit is not that difficult.
First remove the screws holding in the brushes and remove the brushes. Make a note of which direction the 45 degree off set faces or you will have to dissable the entire unit to get the brushes in properly. Remove two screws from the rear of the unit holding the cover between the two halves of the unit (top and bottom). You will need to remove all the screws on the underside of the unit. Approximately 6.
The shaft located vertically has a pin in it which needs to be driven out with a punch/hammer. Then a "C" clip must be removed form the shaft to remove it. If you do not have a "C" clip pliers you can get them at most automotive parts distributors.
Next pry the bezel off around the exterior of the shaft which will expose about 6 screws which need to be taken out. Now you can remove the head assembly as well as the top of the unit exposing the motor armature. When reassembling this drive unit use some Loctite on the threads of the screws to prevent them backing out. This is a common problem with these units.
At this point you should be able to see how burnt the armature is. Using crocus cloth (very fine emery cloth) available at any home improvement store such as Lowes or Home Depot, clean the armature until it shines.
Clean the armature with a solvent to get rid of any filings or debris that was left from the cleaning process and wipe the entire unit clean.
Reassemble the unit and it should be as good as new. Remember to insert the brushes the proper way or the unit will not work. They are keyed.
