7KSM180LEZLB0 KitchenAid Mixer - Instructions

Replaced gears and cleaned and re-greased gears

1. Removed the mixer from the base by removeing the pivot pin at the mixer base support. 2. removed the retainer ring from the housing. 3. removed the pin from the shaft. 4. removed 5 philips machine screws from the round base. 5. removed the round base from the mixer housing. 6. removed the o-ring from the shaft. 7. removed the shaft and large worm/pinion gear from the shaft. 8. pressed out the pinion drive gear from the mixer. The reverse operation repaired the mixer to new condition.

Knob fell out of the front of the mixer into the bowl and jammed the beater. This caused the motor to strip the plastic worm gear. Open unit to investigate and found about 4 teeth missing out of the worm gear. Ordered a replacement. Installed the new gear once received in about 30 minutes. Wife is now happy again. Just need to make sure you pack enough gease into the new gear before reassembling the unit.

removed one screw from back cover, loosened two screws holding speed control plate, removed one wire at a time from old unit to new, screwed two top screws back on mixer,plug mixer back in, adjust speed control screws until I reached correct speed, put back cover back on

Neither motor brush popped out with the spring as shown on videos. Both appear to have disintegrated in part and had to be chiseled out delicately using and ice pick and tapping gently with a hammer. This left a carbon powder and pieces of the old brushes on the counter. Inserting the new brushes was as easy as shown on the video.
