This video from Sears PartsDirect shows how to replace a worm gear in a stand mixer. Located inside the lower cover, the worm gear rotates on the inside edge of the stationary planetary gear to spin the attachment. The worm gear teeth are nylon, so the teeth strip out by design if the drive system binds up. This protects other gears and the motor from damage in the event of a problem. If the worm gear teeth are worn or damaged, then you may need to replace the worm gear.

Located inside the lower cover, the worm gear rotates on the inside edge of the stationary planetary gear to spin the attachment. The worm gear teeth are nylon, so the teeth strip out by design if the drive system binds up. This protects other gears and the motor from damage in the event of a problem.

Using a 5/32-inch drift punch and hammer, drive the pin out that holds the planetary gear housing to the vertical center shaft. Use 2 slot screwdrivers to pry off the planetary gear housing. Remove the power cord from the bottom cover. Remove the 5 screws from around the planetary gear. Remove the 4 mounting screws from the cover. One of the rear mounting screws has a lock washer. Slide the drift punch through the center shaft hole to help lift the bottom cover. Gently pry the bottom cover up and remove it. Remove the 3 Phillips screws and washers from the worm gear bracket. Pull the worm gear assembly up and off. Position the new worm gear assembly on the bottom cover and reinstall the mounting screws and washers. Lubricate the new assembly with grease. Lift the bottom cover and align the gears. Lower the bottom cover into the upper housing, working the gears back into place by slightly twisting the center shaft. Once the gears mesh, lower the bottom cover fully. Reinstall the screws around the planetary gear. Reinstall the screws in the cover. Reinstall the lock washer on the rear mounting screw. Slide the planetary gear housing down onto the center shaft. Using the drift punch, align the mounting pin holes with the hole in the center shaft. Reinstall the mounting pin.
