Einleitung

The powertrain assembly is comprised of the motor, the gearbox, and the transfer gears. Unlike previous generations of KitchenAid AC Motor bowl-lift mixers, which had these broken in to discrete parts, this is a single unit in this model and must be replaced as such.

Note: Depending on the generation of your motor it might have a different coloration than the one in the picture (e.g. older models were all silver). Verify the motor part number before continuing.

    • Before starting ANY repair/disassembly of the mixer, make sure it is fully unplugged from the electrical outlet.

    • If this mixer is being used in a commercial environment, a LOTO tag can be affixed via the hole on one of the prongs on the mains plug to prevent accidental activation.

    • The speed/motor control assembly contains capacitors which can retain their charge for an indefinite amount of time. These capacitors can present a significant and potentially fatal shock hazard.

    • Place a couple dish towels or other soft materials on the base to protect it from any potential impact.

    • Disconnect the planetary from the motor drive shaft by removing the retaining pin (circled in yellow). You can do this with a hammer and either a pin punch or a Torx T15 screwdriver. Simply hammer the punch/screwdriver on the pin until it comes out the other side.

    • If the planetary assembly doesn't fall out, you might have to give it a firm pull straight down to remove it.

    • Using a #2 Phillips Screwdriver, remove the four screws (circled in yellow).

    • When removing the last screw, make sure to place your hand under the planetary gear as it is heavy and will fall out immediately.

    • There are two motor support brackets: one in front, one back (shown in the first image)

    • Each bracket is attached to the motor by two screws (one on each side).

    • Using a #2 Phillips screwdriver, remove the four screws (circled in yblue in the second and third images) which attach the two motor support brackets.

    • Take care to place your hand under the support bracket when removing the second screw as they will fall out and could damage the finish.

    • Disconnect the motor power cable by depressing the locking tab (circled in yellow) while pulling the connector apart.

    • Do not attempt to remove the hall effect sensor, the cord which attaches back by the fan, as it is much more easily removed at a later step.
