A gear lever actuator is provided for remotely or automatically moving the gear lever of a gearbox connected to an engine to be tested. The gear lever actuator comprises a first actuator for moving the gear lever between a neutral plane and gear selecting positions on either side of the neutral plane. Movable jaws are provided for clamping the gear lever during gear changing and for disengaging the gear lever when the engine and gearbox are running under load. The gear lever is then free to jump out of gear upon the occurrence of a fault, thus preventing damage to the gearbox. |
