Garmin GHP 12 Autopilot System Installation Instructions - Page 2

1 Drill a 12. 2 mm (0. 48 in. ) hole in the quadrant or tiller arm À (not included) for the tiller bolt. 2 Place the tiller bolt Á into the quadrant or tiller arm, and secure it with the M12 washer  and the M12 lock nut Ã. It is recommended to apply Loctite 638, or an equivalent retaining compound, to the tiller bolt where it passes through the quadrant or tiller arm. 3 Place the drive unit rod Ä on the tiller bolt. 4 Fasten the rod to the tiller bolt with the other M12 washer Å and the locking pin Æ. Installing the Feedback Sensor To use the drive unit with a Garmin autopilot, the feedback sensor must be installed after the drive unit has been installed. 1 Place the base of the feedback sensor À on the pin at the top of the drive unit Á. 4 Secure the feedback sensor to the pin at the top of the drive unit with the other included M5 washer and other locking pin. Connecting the Drive Unit to a Garmin Autopilot NOTICE The cables connected to the drive unit should not be cut, because cutting the drive-unit cables voids your warranty. Consult the installation instructions provided with your Garmin autopilot to install the autopilot components and to connect the drive unit to the correct component. Maintenance To maximize the life of your drive unit, these maintenance guidelines should be observed. • The cylinder rod should be kept free from damage. • The drive unit should not be exposed to salt water. • The mounting hardware and the tiller-bolt hardware should be inspected on a regular basis, and any components should be tightened if necessary. • The rod end and the tiller bolt should be kept lubricated with marine-grade grease. Only high-quality marine grease that is compatible with nitrile seals should be used. Removing the Drive Unit from the Base The drive unit can be removed from the base for service, if needed. 1 Remove the motor coil, secured by a 17 mm nut À. 2 Loosen and remove the allen screw Á and retaining plate Â. 2 Extend the rod of the feedback sensor if necessary, and place it on the top of the tiller pin Â. 3 Secure the feedback sensor to the tiller pin with the included M5 washer à and locking pin Ä. 3 Remove the mounting pin à to release the drive unit from the base. If the pin is difficult to remove, you can remove the plastic cap from the head of the pin and insert the screw you removed in step 2 to provide a grip for pliers. 2
