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.
