Komatsu PC300-6 hydraulic pump piston sub 708-2H-23311

Piston Assembly: The piston assembly in a hydraulic pump is a critical part responsible for reciprocating motion within the pump. It is driven by the pump's mechanism to create pressure within the hydraulic fluid.

Piston Subassembly: A piston subassembly could refer to a group of components related to the piston, such as the piston, piston rings, piston rod, and associated seals. It's common to have subassemblies to simplify maintenance and replacement.

Piston Rings: Piston rings are circular bands fitted around the piston. They create a seal between the piston and the cylinder, preventing hydraulic fluid from leaking and ensuring efficient operation.

Piston Rod: The piston rod connects the piston to the hydraulic pump's drive mechanism. It translates the reciprocating motion of the piston into rotational motion, driving the pump.

Seals and Gaskets: Subcomponents may include seals and gaskets that ensure a proper seal between the piston and the cylinder, preventing leaks and maintaining hydraulic pressure.
