Hydraulic Pump Repair Kits Cylinder Block PSVD2-26E PSVD2-27E For KAYABA Excavator Spare Parts Drive swash plate movement and vary pump output displacement Joined to the swash plate, the servo piston makes linear reciprocating strokes actuated by pilot pressure oil to adjust how much the swash plate tilts: Greater tilt angle increases pump displacement and boosts outgoing flow. Reduced tilt angle decreases pump displacement and cuts outgoing flow. Enable load sensing and

Excavator Parts Ap12 Set Plate Hydraulic Pump Ass'y Spare Parts For Cat E200b E320b Excavators Restrain all piston shoes and prevent them from separating from the swash plate. During high‑speed rotation of the cylinder block under high pressure impact, the spring pushes the cylinder block to press the piston shoes against the inclined surface of the swash plate. The set plate encircles the tails of all piston shoes to restrict them from flying outward, ensuring the piston

E325b A8VO107 099-5713 Piston Shoe Hydraulic Main Pump Part 1232229 Excavator Pump Parts Fit and slide against the swash plate The bottom surface of piston shoe slides on the swash plate. When the cylinder block rotates, the swash plate incline pushes pistons to reciprocate inside cylinder bores for oil suction and discharge. Hydrostatic bearing for friction reduction High‑pressure oil flows through the orifice to the shoe bottom, forming an oil film to separate metal contact
