Very easy fix. Unplugged microwave, then lowered bottom panel, removed the two leads to the turntable motor, removed two screws attached to motor, removed old motor, put new spacer on motor stem, installed motor with same two screws, reattached the two wires, reattached panel ( after cleaning all the grease that built up over the last 6 years), plugged microwave in and good as new! Took me twenty minutes. Note: the two screws holding the motor were not Phillips like those holding the panel. So I had to take the time to search in my tools for a square head driver.
