Actuator Bracket
The actuator may be installed on a bracket holding to the 2.248–2.251 inch
diameter male pilot concentric to the terminal shaft or to a bracket which attaches
to the base with four .312-18 screws with a minimum engagement of 16 mm
(0.625 inch). The actuator may be mounted in any attitude. The actuator is
weather proof and resistant to the corrosive effects of water and salt water,
however pressure washing of the feedback device side of the actuator should be
minimized.
Replace the four outside through bolts with longer .250-20 bolts when mounting on a
fixture locating on the pilot diameter. Torque the bolts to 7.3 to 8.5 N·m (65 to 75 lb-in).
The actuator will fall apart if the inner bolts are removed.
When mounting on the bottom of the actuator, torque the attaching bolts to 17 to
18 N·m (150 to 160 lb-in).
