R.A. Motor Removal
1. Disconnect the R.A. Motor cable (7 Pin connector) from the Printed Circuit Board.
2. Remove the 2 hex (Allen) screws holding the RA Motor assembly to the drive base.
Be very careful you don't drop the hex screws down into the base as it's very difficult
to retrieve them, and you could jam the worm gear.
3. Remove the drive assembly. Note there is a spring located between the two sides of
the motor assembly that ensures proper meshing of the worm with the worm wheel.
Keep pressure on the motor assembly hinge while removing it so the spring doesn't
fall out when pressure is released.
