Woodward governor/actuator recommended maintenance schedule:
- Change governor/actuator oil between 3,000 and 5,000 running hours
- Ensure the use of proper oil
- Perform overhaul and calibration between 20,000 and 25,000 running hours
- Repair of auxiliary equipment is also recommended
Catastrophic failure may result if your governors are pushed past recommended limits of maintenance, i.e. seizure of oil pump, bearing failures, etc. If your prime mover is critical to your operations, a recommended preventive maintenance schedule should be followed. Repair costs can be excessive when units are operated beyond the hours of recommended maintenance.
