Swash plate for Terex HC230

The swash plate, identified by part number 0781 143 51, is a critical internal component within the axial piston pump assembly of the Terex HC230 crane. It serves as the mechanical interface that determines the stroke length of the pistons during pump operation. By adjusting the angle of this plate, the system modifies the displacement of the hydraulic pump, which directly influences the output flow and pressure delivered to the crane hydraulic circuits.

This component is designed specifically for the Terex HC230. It functions within the pump housing to convert rotational movement into the reciprocating action required for fluid displacement. Proper alignment and surface integrity of the swash plate are necessary for the pump to maintain consistent pressure levels during crane operations, including lifting, slewing, and boom extension.

In axial piston pumps, the swash plate acts as the primary control mechanism for variable displacement. By tilting the plate relative to the drive shaft, the pump can vary its output volume without changing the rotational speed of the input shaft. This allows for precise control over the speed and force of hydraulic actuators throughout the machine.
