Excavator Pump Parts Hydraulic Pump Repair Parts PSVD2-26E/27E Set Plate for KYB Kayaba Excavator Control the movement of all piston shoes and prevent them from pulling away from the swash plate. As the cylinder block rotates rapidly under heavy high‑pressure loads, springs push the cylinder block to press piston shoes onto the swash plate inclined plane. The set plate wraps around piston shoe tails to restrain outward flight, ensuring persistent contact between piston shoes

Excavator Parts PSVL-54 Hydraulic Repair Parts Kit for KYB Kayaba Kubota 6T 155 Excavator Pump Parts Alter swash plate inclination and adjust pump displacement Coupled to the swash plate, the servo piston undergoes linear back‑and‑forth movement under pilot hydraulic oil pressure to change the swash plate tilt: Expanded swash plate angle leads to higher pump displacement and stronger output flow. Contracted swash plate angle leads to lower pump displacement and weaker output

PSVL-54 Hydraulic Pump Swash Plate PSVL-54 Piston Pump Cam Rocker Excavator Pump Parts The swash plate is a key internal part for excavator main pumps. It stays static while cylinder block rotates; piston shoes slide on its surface. Functions Piston shoes bear against swash‑plate face. Swash‑plate inclination converts cylinder‑block rotary motion into pistons’ reciprocating linear motion for oil suction and pressure delivery. Pump displacement varies with swash‑plate

Excavator Parts SA8230-03340 SET PLATE RETAINER FOR MAIN PUMP FITS EC55B AP2D25 Pump 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

Ap2d21 Pump Repair Parts Valve Plate Excavator Pump Replaecment Parts Valve plate porting and commutation: As the cylinder block rotates, each piston chamber is automatically alternately connected to the high-pressure and low-pressure ports to complete oil suction and discharge, replacing a separate directional valve. Sealing and isolation: Forms an oil film friction pair with the end face of the cylinder block, isolates high-pressure and low-pressure chambers, and prevents

Excavator parts AP2D21 Hydraulic Piston Pump part Ball Guide for Hydraulic Pumps UC1100195746 It is the swash plate mounting base. Mount swash plate on the support; the support pivots on the pivot shaft to adjust swash plate tilt angle. Full assembly sequence: Drive Shaft → Cylinder Block → Ball‑Guide → Set‑Plate → Piston Shoe → Swash Plate → Support Ⅱ. Core Functions Load-bearing & mounting: Positions swash plate and bears heavy thrust loads from piston shoes. Swing pivot:

Excavator Pump Parts Hpv75 Piston Shoe 708-1W-33310 Set Of 9 Pc Fits For Pc60-7 Pump Attached to the spherical end of the piston, the piston‑shoe slides against the swash‑plate surface. Its tail passes through the holes of the set‑plate. Core Functions Sliding load‑bearing: Its bottom surface slides on the swash‑plate and bears high pressure loads, preventing direct friction between the piston ball‑head and swash‑plate. Oil‑film lubrication: High‑pressure oil flows through

Excavator Pump Parts REPLACEMENT REXROTH A10V71 BALL GUIDE R902443449 Excavator Parts This is the mounting base for the swash plate. The swash plate mounts to the support, which swings on the pivot shaft to adjust the swash plate’s tilt angle. Complete assembly lineup: Drive Shaft → Cylinder Block → Ball‑Guide → Set‑Plate → Piston Shoe → Swash Plate → Support Ⅱ. Core Functions Load-bearing & mounting: Holds the swash plate and carries heavy thrust loads transferred from

Excavator Pump Replacement Parts A10V71 SET PLATE R902437512 Excavator Spare Parts Core Functions Enable piston return for oil suction. The swash plate drives pistons inward to build oil pressure. As components rotate to the suction side, pressure drops. The Set Plate retains all Piston Shoes and pulls pistons out of the cylinder block, expanding cylinder bore volume to draw in oil. Locate and restrain every piston shoe. Each piston shoe neck runs through holes in the set

AP2D-36 Drive Shaft 277-3201C Compatible With DH80 Main Pump ZX70 Main Pump Excavator Pump Parts Commonly referred to as main pump drive shaft or hydraulic pump input shaft. It accepts engine drive power and rotates the cylinder block. Main Functions Transfers engine torque to facilitate high‑speed cylinder block rotation Produces hydraulic energy by driving piston shoes through repeated oil suction and discharge strokes Common Failures Spline wear and key displacement: Power

Excavator Pump Parts AP2D21 Spare Part For Hydraulic Pump When the pump rotates at high speed, the retainer plate pushes all piston shoes backward continuously. As a thrust washer, the shoe plate bears the axial force from the retainer plate, separates the retainer plate from the pump housing and prevents direct wear of the housing. It forms a sliding friction pair and builds up oil film lubrication. A hydrostatic lubricating oil film is formed on both surfaces to reduce

This is primarily the main pump drive shaft, namely the hydraulic pump input shaft. It takes engine power and turns the cylinder block. Main Functions Conveys engine torque to spin the cylinder block at high speed Moves piston shoes for cyclic oil intake and discharge to generate hydraulic power Common Failures Worn splines & sheared keys: Power transfer slip, low pump performance Scuffed shaft surface: Oil seal leaking Bent or broken shaft: Strange noise, total pump

Excavator Pump Parts HPV75 SET PLATE 708-1W-23340 For Pc60-6 Pc60-7 Excavator Located between the Piston Shoe and Swash Plate, it is a circular steel plate with round holes corresponding one‑to‑one to the number of pistons. The tail of each piston shoe passes through these holes. It works as a matched component with the Ball‑Guide: Cylinder Block → Ball‑Guide → Set‑Plate → Piston Shoe → Swash Plate Core Functions Retain piston shoes (return‑stroke function): During the piston

Excavator Parts AP2D36 Swash Plate AP2D36 Hydraulic Pump Parts The swash plate is a core inner part for excavator main pumps. It does not rotate with the cylinder block. Instead, piston shoes slide along its surface. Functions Piston shoes press to the swash‑plate face. As the cylinder block rotates pistons, the tilted swash plate converts rotation into pistons’ reciprocating movement for oil suction and pressure delivery. Swash‑plate tilt controls pump displacement. Larger
