HOW IT WORKS

Converting Hydraulic Pressure into Starting Torque

Hydraulic starting uses pressurized fluid to produce the rotational force needed to bring an engine up to starting speed. In turbine and reciprocating engine applications, this allows hydraulic power to be converted into mechanical motion through the starter assembly.

The hydraulic drive configuration supports high starting torque efficiency and high-speed operation, making it suitable for demanding applications where controlled startup performance is required.

Hydraulic Pressure Conversion

Uses pressurized fluid to generate rotational starting force.

Efficient Torque Delivery

Supports high starting torque efficiency during the startup sequence.

Circuit Flexibility

Works with open or closed loop hydraulic circuit designs.

Starter Drive Protection

Includes an overrunning clutch to support proper drive behavior as the engine accelerates.

Hilliard Hydraulic Start Assemblies use hydraulic power to drive the starting mechanism and transfer torque through the shaft connection to the engine. Once the engine reaches the required operating condition, the overrunning clutch supports disengagement of the starter drive from the running engine.
