Common Questions & Answers

Q: Is the 8405-029 compatible with my existing Woodward governor?
A: The 8405-029 works with most Woodward 505, 2301, and 8400-series governors. Verify electrical signal compatibility (4-20mA or 0-10VDC) with your specific controller model.

Q: What hydraulic supply pressure is required?
A: The actuator requires a clean hydraulic supply between 1500-3000 PSI. Ensure your system includes adequate filtration (10-micron recommended) to prevent contamination.

Q: Can this actuator be used in marine environments?
A: Yes, the IP65-rated enclosure and corrosion-resistant construction make it suitable for marine applications. Additional protective coatings are available for extreme saltwater exposure.

Q: What is the expected service life?
A: Under normal operating conditions with proper maintenance, the 8405-029 typically provides 50,000+ hours of reliable service. Regular inspection and hydraulic fluid quality are key factors.

Q: Is calibration required after installation?
A: Initial calibration is recommended to match the actuator stroke to your specific fuel rack geometry. Woodward service tools or compatible controllers provide calibration procedures.
