guide to the up (vertical) position to help with removing and re-installing the Main Drive
Assembly.
16. Make sure the gears are aligned properly before installing the main drive assembly. The four

right (they may fall off when removing the MDA), align with the three large bottom gears.
Notice the two holes on each of the small gears align with the small holes of the large gears.
