UNIT REMOVAL AND REINSTALLATION

6.1

GTX 330/330D

Removal:
1. Insert the hex drive tool into the access hole on the unit face and rotate counterclockwise until the unit
is forced out about 3/8 inch.
2. Pull the unit straight out of the rack.
Reinstallation:
NOTE
It may be necessary to insert the hex drive tool into the access hole and rotate the cam
mechanism 90° counterclockwise to insure correct position prior to placing the unit in
the rack.
1. Slide the GTX 330/330D in the rack straight in until it stops, about 1 inch short of the final position.
2. A 3/32-inch hex drive tool is then inserted into the access hole at the bottom of the unit face.
3. Rotate the hex tool clockwise while pressing on the left side of the bezel until the unit is firmly seated
in the rack.
4. Count the number of complete revolutions the Allen screw can be turned until it cannot turn any
more. Take care not to over-tighten. Three (3) turns is the minimum for proper installation. If fewer
than three (3) turns are possible, ensure there are no obstructions to the unit fully seating in the rack.
Also, the mounting rack may need to be moved aft (toward the pilot) such that the aircraft panel does
not obstruct the unit from properly engaging in the rack.
CAUTION
Be sure not to over-tighten the unit into the rack. The application of hex drive tool
torque exceeding 15 in-lbs can damage the locking mechanism.
