Servo Control Orifice Reassembly
1. Install the orifice (G020), and torque to 2.7 N•m [23 in•lb]. Then install the orifice backup plug (G030),
and torque to 2.7 N•m [23 in•lb].
2. Install the PC spool (C132), spherical end first, into the PC bore. Install plug (C103). Torque the plug to
12 N•m [8.9 lbf•ft].
3. Using petroleum jelly to retain them, install the four O-rings (C200) in the recesses on the control
housing.
4. Install the control assembly onto the endcap using four screws (C300). Torque the screws to 6.5 N•m
[4.8 lbf•ft]. Torque screws in a criss-cross pattern and re-torque the first screw to ensure proper torque
retention.
