PSVL-54CG-16 RD411-61113 RD538-61111 RD538-61112 RD538-61115 Main Hydraulic Pump for Kubota KX161-3 KX161-3S Mini Excavator

1. OEM Part Number & Machine Compatibility

Original pump model: KYB PSVL-54CG-16 single variable displacement axial piston pump assembly
Kubota OEM part numbers: RD411-61113, RD538-61111, RD538-61112, RD538-61115
Fully compatible excavator models: Kubota KX161-3, KX161-3S
All four part numbers are iterative supersession replacement numbers, with identical external mounting dimensions and internal hydraulic parameters, fully mutually interchangeable for direct replacement installation

2. Core Technical Specifications

Structure type: Variable axial piston main pump (first stage + second stage) integrated with built-in pilot charge gear pump
Displacement: 54 cm³/rev, precisely matched to factory load-sensing hydraulic system configuration of KX161-3 / KX161-3S midi excavator platform

Second Stage Specified Parameters

Rated working pressure (second stage): 24.5 MPa
Maximum relief pressure (second stage): 28.0 MPa
Rated operating speed (second stage): 2200 rpm
Corresponding rated input power (second stage): 51.8 kW
Operating speed range calibrated to match the rated output speed of original engine equipped on these two excavator models
Mounting hole layout, input shaft spline size and hydraulic port position strictly conform to Kubota OEM dimensional drawings
Pump housing adopts high-strength ductile iron; internal pistons, valve plates and friction wear components are made of quenched wear-resistant alloy steel to improve abrasion resistance and extend service life

3. Internal Structure & Functional Introduction

Variable main piston pump outputs high-pressure hydraulic oil to drive boom, arm, bucket, travel and swing composite movements
Integrated pilot gear pump supplies stable pressure oil for pilot control circuit and system hydraulic oil replenishment
Built-in load-sensing power regulator automatically adjusts pump total flow output according to real-time load variation, effectively preventing engine stall during heavy digging and loading operations
Compact integrated structure fits perfectly inside the reserved hydraulic compartment space of KX161-3 and KX161-3S excavators

4. Product Advantages

Exact 1:1 OEM casting external size, supporting plug-and-play installation without modifying hydraulic pipelines or chassis mounting structure
Every finished pump passes comprehensive hydraulic bench test before shipment, including pressure stability, flow consistency and internal leakage inspection
Complete overhaul spare parts are in stock, including seal repair kits, piston assemblies, swash plates and valve plates for individual component replacement during maintenance
Multiple supersession OEM numbers correspond to two machine versions, simplifying spare part ordering, classification and inventory management for dealers and repair workshops

5. Packaging & Global Delivery Details

Input shaft and all hydraulic ports are coated with anti-rust grease and sealed with dust-proof plugs
The whole pump is wrapped with moisture-proof plastic film and fixed inside export solid wooden case to avoid collision and damp corrosion during long-distance sea or air transportation
In-stock products can be arranged for delivery within 3–5 working days after order confirmation
Multiple global shipping solutions are available: international express, sea LCL/FCL bulk shipment, and overland truck transport for Southeast Asian markets

6. FAQ

Q: Are RD411-61113, RD538-61111, RD538-61112, RD538-61115 interchangeable with each other?

A: Yes, these four part numbers are upgraded replacement codes for the same KYB PSVL-54CG-16 pump assembly, fully cross-replaceable for KX161-3 and KX161-3S.
Q: Can this pump be directly installed on both KX161-3 and KX161-3S?

A: Yes, unified mounting dimension and factory preset hydraulic calibration enable direct bolt-on installation for both models without extra adjustment or modification.
Q: What is the relationship between PSVL-54CG-16 and these Kubota OEM numbers?

A: PSVL-54CG-16 is the official model designation of KYB original pump, while the four serial numbers are exclusive OEM part numbers assigned by Kubota for this complete main pump assembly.
Q: Are separate repair spare parts available for this hydraulic pump?

A: Matching full overhaul seal kits, piston shoe assemblies, valve plates, swash plates and independent pilot gear pump spare parts are all available for partial overhaul and single component replacement work.
