    Once the Nylon gear removed, you have 2 bearings, the middle one is to support the rotor (model # 628RS) and the bigger one is for the version B pinion (Model # 16002RS)

    Next the final one is the stator with the hall sensor circuit board, you can see the actual hall sensors that are inserted in the stator slots marked H1 H2 H3.
