Three phillips-head screws held the "Cap Screw" in place on the stand of the mixer. After cleaning the stuff out of the screw slots, the screws came out surprisingly easy. After the plate was lifted off, we cleaned the residue from under the plate, placed the new one in position and easily screwed in the 3 screws.
We were very pleased by the quick delivery of the part.

Punched out the roll pin to remove eccentric from spindle, undid 5 screws (after removing trim ring), and removed 4 screws to undo the motor housing. Make sure to keep the one screw with a lock washer in the BACK of the housing. Undid the screw on top to remove the back of the motor housing to take out the strain relief grommet, prior to removing the motor housing. Scraped the excess grease into a tub to re-use. Pulled out the shaft, and lifted out the old (stripped) gear and plopped the new one in. Make sure to mark match points for parts, and put the pins back in in the right order. You have to put the 5 screws back in before sliding the trim ring on, and putting the roll pin back. make sure all gears mesh and test before snugging the motor housing screws. Be sure to orient the strain relief grommet securely, and be careful of the filter plates in the back of the housing (they're brittle). putting the grease back is like frosting a cake. Save a little for the planetary ass'y.

Obviously the problem was in the gear box of the mixer. I disassembled the gear box by removing the four large screws holding the base then the four screws at the rear and center of the mixer. Then I removed the thin metal ring covering the five screws around the front of the housing by gently prying up with a small screwdriver. The five screws beneth the ring have to be removed with a small blade screwdriver turning them a round at a time in sequence until they are free. Gently pry the two housings apart with a screwdriver and lift our the lower half with the plantary gears. I found the drive gear was stripped. I went to PartSelect on the web, eaisly found the exploded view of the mixer's gear box and ordered the gear I needed. The gear is part of an assembly attached to the mixer housing with three screws. Work around the lubricant in the housing. Within four days I received the new gear, installed it by reversing the above procedures and the mixer is working again. The total cost was $34.85. Not a bad investment considering the mixer cost over $400 and would have been trashed for want of one part.

stripped nylon drive gear

Followed the repair instructions from the manual. ...

I did notice that the replacement part had an extension on it that allowed for the gear grease to be "pulled up" onto the drive gear ( the one that broke), while the unit is running. This feature was not on the original part, but was obviously an upgrade design which was added after my particular mixer was made. I think that the extension on the bracket will help prevent the new nylon gear from binding and stripping as we use the mixer from now on.

I'm glad that PartSelect had the more modern part on hand, and not just an "overstock" from the original, inferior design.
