Woodward Service


Woodward Governor continues to meet the demands for more efficient engine management, exhaust emission control, digital control systems, air and fuel valves, engine ECUs and power management controls.

Woodward Governor’s leading-edge diesel engine control systems help you to achieve maximum efficiency and minimum emissions from your engines. Software is easy to use. Controls use digital electronics, electric and hydro-mechanical auxiliaries and servo actuation systems and on-engine accessories.

Our control solutions include speed control, fuel control, integrated speed/fuel control and integration of ancillary devices. Quality and performance are assured through the use of advanced control algorithms, system analysis and system modeling to verify application before installation.

For a range of applications, we can offer upgrading of the mechanical governors to electronic versions, replacing the old mechanical governor with an actuator that is designed to fit directly onto the same drive. An electronic control panel is tailored to add additional benefits, e.g. better electronically controlled load sharing between engines.

Recommended maintenance schedule for Woodward Governors and Controls


        • Ensure that the oil used in the Governor/Control is as per Woodward manual 25071
        • The Governor/Control oil should be changed between 500 and 3.000 running hours depending on operating conditions.
