China Parts for KOBELCO SK350-8 Main K5V140DTP Pump | Tonkee®

Pump Housing: The pump housing is the main body of the K5V140DTP pump.

It houses various internal components and provides structural support.

Swash Plate: The swash plate is a critical component that converts the rotational motion of the pump into linear motion. It consists of a tilted plate attached to the pump shaft, and as the shaft rotates, it pushes the pistons back and forth.

Piston Shoe: The pump has multiple piston shoes that are pushed by the swash plate. These shoes help generate pressure by reciprocating inside the cylinder block.

Cylinder Block: The cylinder block contains multiple cylinder bores where the piston shoes slide back and forth. It is responsible for guiding the pistons and controlling the flow of hydraulic fluid.

Valve Plate: The valve plate is located between the cylinder block and the pump housing. It contains various valves and ports that direct the flow of hydraulic fluid to different parts of the excavator's hydraulic system.

Drive Shaft: The drive shaft connects the K5V140DTP pump to the engine or motor of the excavator. It transfers the rotational power to the pump, enabling it to generate hydraulic pressure.

Bearings: The pump incorporates various bearings to support the rotating components and reduce friction.

These bearings ensure smooth operation and help prolong the lifespan of the pump.

Seals and O-rings: Seals and O-rings are crucial for preventing hydraulic fluid leaks and maintaining the pump's efficiency. They are located at various points throughout the pump and help create a tight seal between moving parts.
