7. Carefully twist and lower the actuator into the girdle support bracket
until the spring pin locates into the opposite side of the girdle tube.
Caution: It is most important that both the solid and spring location pins
are fully engaged in the actuator girdle tube. Failure to do so will result in
autopilot failure and possible steering system damage.
8. Position the drive unit pushrod over the top of the adaptor pin and
secure with the safety clip.
9. Slowly turn the steering system from hard-over to hard-over. The drive
unit and the adaptor pin bracket must not touch any part of the engine
or steering system. This includes any engine hoses that may have
only passing contact with the autopilot actuator; after a time these
will wear and ultimately fail.
