LIUGONG 11C4160 Excavator Main Hydraulic Piston Pump Assembly

● LIUGONG 11C4160 Hydraulic Pump Technical Support

● Part number 11C4160 (engineering model K5V160DTH-9N4A / replacing earlier revision 11C2672) is the genuine tandem variable-displacement axial piston main hydraulic pump assembly engineered for LIUGONG heavy crawler excavators.

● Material number 11C4160 is coupled directly to the engine flywheel damper via a flexible coupling. Utilizing twin high-pressure swashplate cylinder blocks and proportional electronic regulator valves, it dynamically modulates high-pressure oil output to supply the main control valve, powering boom hoist, arm crowd, bucket digging, swing, and crawler travel circuits.

● Inspect pilot control pressure lines, pump regulator solenoid signals, case drain filter elements, and hydraulic oil cleanliness during scheduled excavator maintenance.
