DX225-9C DX230-9C 100201-02469 Doosan DX215-9C Hydraulic Pump DPA117 Spare Parts Repair Kit Parts Full Hydraulic Pump Overhaul Kit (Best Seller) ✅ Piston shoe assembly ✅ Cylinder block ✅ Valve plate ✅ Swash plate & thrust plate ✅ Retainer plate, ball hinge, positioning pins, springs, bearings ✅ Complete package of oil seals, O-rings, gaskets and sealing elements Applicable Issues Low main pump pressure and inadequate digging capacity Abnormal pump sound and sustained high oil

Excavator Hydraulic Pump Kit Swash Plate for Rexroth A10VS063 R902429370 Excavator Parts Used in excavator main pumps, the swash plate is a vital internal component. It stays still while the cylinder block rotates, and piston shoes glide over its surface. Functions Piston shoes rest against the swash‑plate face. When the cylinder block rotates pistons, the slanted swash plate turns rotary movement into pistons’ back‑and‑forth movement for oil intake and pressurized oil output

Excavator Hydraulic Pump Parts PSVL-54 Set Plate Spare Parts Excavator Parts Hold every piston shoe captive and prevent separation off the swash plate. Under high pressure impact during cylinder block high‑speed rotation, spring force pushes the cylinder block to press piston shoes firmly against the swash plate inclined surface. The set plate encircles piston shoe tails to restrict outward flying motion, guaranteeing continuous fitting between piston shoes and swash plate
