Governors & Actuators
The hardware that holds a diesel engine at frequency under changing load — GAC electronic governors, actuators, magnetic pickups and the linkages between them.
Speed control for diesel engines
Governors America Corp make the speed governing hardware that holds a diesel engine at frequency under changing load. We stock the range in Brisbane: electronic speed control units, the actuators they drive, magnetic speed pickups, and the harnesses, brackets and linkages that connect them.
Most enquiries here are replacements for a failed unit on an existing set. If you have the part number from the old unit, find it below. If you only have the engine and the symptom — hunting, drooping under load, failing to reach rated speed — send us those and we will work out what you need.
