Azimuth Motion Stops
4.7.1
Current Configuration (Since August 2004)
The current Azimuth stop configuration was introduced in August 2004. It consists of two adjustable
stop blocks. Each stop block is attached to the Azimuth Adapter ring by two shoulder bolts (Figure
12). The stop blocks limit movement of the Gimbal when the stop blocks come into contact with a
high- strength stationary shoulder bolt that is mounted on the Gimbal Arm through the doubler. You
can detach and reposition the stop blocks to restrict Azimuth movement according to your installation
and aircraft requirements.

Inspect the Azimuth stops by checking the torque of the following:
