PSVL-42CG-20 RD829-61110 RD829-61112 RD829-61113 RD829-61115 Main Hydraulic Pump for Kubota KX080-4 Mini Excavator Parts
1. OEM Part Number & Machine Compatibility
Original pump model: KYB PSVL-42CG-20 tandem variable displacement piston pump assembly
Kubota OEM part numbers: RD829-61110, RD829-61112, RD829-61113, RD829-61115
Exact compatible excavator model: Kubota KX080-4
All four listed part numbers are successive supersession upgrade numbers, sharing identical external mounting dimensions and internal hydraulic configuration, fully interchangeable for direct replacement installation
2. Core Technical Specifications
Structure type: Dual variable axial piston main pump (first stage + second stage) integrated with built-in pilot charge gear pump
Displacement per main pump: 42 cm³/rev, perfectly matched to factory load-sensing hydraulic system configuration of KX080-4 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): 45.2 kW
Overall working speed range precisely calibrated to match rated output of original V3307-CR engine equipped on this machine
Mounting bolt layout, input shaft spline dimension and hydraulic port positioning strictly comply with Kubota OEM dimensional drawings
Pump housing adopts high-strength ductile iron; internal pistons, valve plates and friction wear components use quenched alloy steel to improve abrasion resistance and extend overall service life
3. Internal Structure & Functional Introduction
Dual main piston pumps generate high-pressure hydraulic oil to drive boom, arm, bucket, travel and swing compound working movements
Integrated pilot gear pump supplies stable pressurized oil for pilot control circuits and system hydraulic oil replenishment
Built-in total power matching regulator automatically adjusts total pump flow output responding to real-time load changes, preventing engine stall under heavy digging and loading conditions
Optimized tandem compact layout fits neatly inside the designated hydraulic compartment of KX080-4 medium mini excavator
4. Product Advantages
Exact 1:1 OEM outer casting dimensions, supporting plug-and-play installation with no modification required for hydraulic pipelines or engine mounting structure
Every finished pump undergoes comprehensive hydraulic bench inspection including pressure stability, flow uniformity and internal leakage testing before shipment
Complete maintenance spare parts are kept in stock, including overhaul seal kits, piston assemblies, swash plates and valve plates for separate component replacement during overhaul work
Multiple supersession OEM numbers fit one machine model, simplifying spare part ordering, stock classification and inventory management for suppliers and repair service centers
5. Packaging & Global Delivery Details
Input shaft and all hydraulic ports are coated with anti-rust grease and sealed with protective dust plugs
The entire pump is wrapped with moisture-proof plastic film and secured inside export-grade solid wooden crate to avoid collision and moisture corrosion during long-distance sea or air transportation
In-stock items can be dispatched within 3 to 5 working days after order confirmation
Multiple global shipping solutions are available: international air express, sea LCL/FCL bulk shipment and overland truck transportation for global customers
6. FAQ
Q: Are RD829-61110, RD829-61112, RD829-61113 and RD829-61115 mutually interchangeable?
A: Yes, these four part numbers are iterative updated replacement numbers for the same KYB PSVL-42CG-20 pump assembly, fully cross-replaceable for Kubota KX080-4.
Q: Can this pump install directly on KX080-4?
A: Yes, unified mounting sizing and factory-calibrated hydraulic settings enable direct bolt-on fitting for KX080-4 with no extra adjustment or modification work needed.
Q: What is the relation between PSVL-42CG-20 and these Kubota OEM part numbers?
A: PSVL-42CG-20 is the official KYB original pump model designation, while the four RD829 serial numbers are exclusive OEM part numbers assigned by Kubota for this complete main pump assembly.
Q: Are individual repair spare parts available for this hydraulic pump?
A: Corresponding full overhaul seal kits, piston shoe assemblies, valve plates, swash plates and standalone pilot gear pump spare parts are all available for partial overhaul and individual component replacement work.
