Reinstallation
1. Inspect the electrical and coaxial connectors and pins for signs of damage. Repair any damage.
2. Reconnect the electrical connector and GPS coaxial connector (if installed) to the G5 unit.
3. Reconnect the pitot and static lines to the G5 unit. The ports are labeled on the unit using the
abbreviations “P” and “S” respectively.
4. Insert the alignment pin located at the top of the unit into the mating hole in the mounting ring,
pushing the unit flush with the instrument panel.
5. Insert a hex drive tool through the access hole in the front cover of the G5 as shown in Figure 6-1
and tighten the unit to the instrument panel using 10-12 in-lbs torque.
6. Proceed to Section 7 for configuration and testing.
If a replacement G5 unit is being installed in an instrument panel greater than 0.150 inch thick, the
captive mounting screw must be replaced with a longer #6-32 hex socket head screw. To replace the
captive mounting screw, remove the two #4-40 flat head Phillips mount plate screws, the G5 screw mount
plate, and the captive screw as shown in Figure 6-2. Install a longer #6-32 hex socket head screw and
reinstall the screw mount plate. Ensure correct orientation of the screw mount plate before applying 6-8
in-lb. of torque to the #4-40 mount plate screws.
