Abstract:
A hydraulic system having a clutch assembly (30) which is hydraulically actuated, a pressure device (32) in fluid communication with the clutch assembly, and a multi-position actuator device (34) in fluid communication with the pressure device and the clutch assembly. The position of the actuator device includes at least a first position in order for the pressure device to fluidly communicate with the clutch assembly, a second position for maintaining fluid pressure in the clutch assembly, and a third position for bleeding the hydraulic system.
