The RAM T0 Hydraulic linear actuator combines a cylinder, pump, motor, clutch, and reservoir in a pre-filled, sealed unit. Designed to be used on vessels fitted with mechanical primary steering that can be back-driven. When the clutch is disengaged the cylinder is free and moves with the primary steering. To operate the unit in autopilot mode the course computer energizes the clutch solenoid coil and runs the bidirectional motor to extend and retract the ram. Internal relief valves protect the unit and its mountings from rudder strikes, grounding, etc
