Installation notes
Always consult the applicable maintenance manual for the full installation procedure before performing this work.
- Inspect the flyweight pin, flyweight bores, and mating retainer surfaces for wear, brinelling, or distortion before installing the retainer screw.
- Use the torque, thread treatment, and locking method specified in the applicable Woodward governor maintenance manual to avoid loosening or distortion of the retainer hardware.
- After assembly, verify free movement of the flyweight system and confirm no binding through the full range of motion.
