Equipment Overhauls

Woodward Gateshaft Governor Overhaul

The governor is completely disassembled from the ballhead down to the relay valve including the relay valve plunger, pilot valve, compensating dashpot, speed adjustment assembly and all pivot pins, linkages and levers.

All components are cleaned and inspected for excessive wear or damage. Parts that do not pass inspection, along with all bearings, packings and gaskets are exchanged with OEM or equivalent replacement parts.

The image above shows the components ready for reassembly.

After assembly, the governor is re-calibrated prior to re-starting the Unit. During start-up, synchronizing and loading of the Unit, the governor is observed, adjusted and tuned for optimum control both off and on-line.
