To access the interior of the mixer, I first removed the single screw holding the cup-shaped part at the rear. Then I removed the 4 large screws on the under surface of the mixer head. Next I removed the bright metal ring around the planetary gear area by prying it off. I then pried the dish-shaped part off the shaft using a large-bladed screwdriver. This exposed 5 screws on the circumference of the planetary gear. By removing them, one can pull up the gears and see into the area below. I found the worm gear had fractured. By removing 3 screws at the base I extracted it for closer inspection, checking for any loose pieces. Beware of the jelly-like grease. The replacement part goes into position, and one then follows the steps in reverse.

stripped nylon drive gear

  • Customer: James from Naperville IL
  • Difficulty: Really easy
  • Time to Complete: 30 - 60 mins
  • Tools Required: Pliers, Screw drivers

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.

This is the tightening screw that holds the attachments into the motor unit of the mixer. Found your web site and reordered 2 replacement pieces (in case one breaks!). Very EZ and user friendly. Thank you!

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.

I did not do the repair myself, however, I contacted a suggested service company which in turn was a company I had used before when I had problems with my JenAir microwave. Excellent service, prompt and very professional. Thank you JenAir for your assistance in providing promptly the parts needed to complete this job.

VERY HAPPY
