RC788-61112 RC788-61113 RC788-61122 RC788-61123 RC788-61124 Main Hydraulic Pump for Kubota U35-4 KX033-4 Mini Excavator

1. OEM Part Number & Machine Compatibility

Original pump model: Nachi PVD-0B-28P-6G3-5243A tandem variable displacement piston pump assembly
Kubota OEM part numbers: RC788-61112, RC788-61113, RC788-61122, RC788-61123, RC788-61124
Fully compatible mini excavator models: Kubota U35-4, KX033-4
All five listed part numbers are upgraded supersession versions with identical mounting structure and internal hydraulic configuration, fully interchangeable for direct replacement on these two machine models

2. Core Technical Specifications

Structure type: Dual variable axial piston main pump integrated with built-in pilot charge gear pump
Main pump displacement: 28 cm³/rev × 2; pilot gear pump displacement: 10.8 cm³/rev
Rated continuous working pressure: 23.5 MPa; preset maximum relief pressure: 27.0 MPa for system overload protection
Rated operating speed range: 2200–2400 rpm, precisely matched to the original D1703 engine configuration of U35-4 and KX033-4
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 components use quenched wear-resistant alloy steel to extend service lifespan

3. Internal Structure & Functional Introduction

Dual main piston pumps output high-pressure hydraulic oil to drive boom, arm, bucket, travel and swing operational movements
Integrated pilot gear pump supplies stable pressurized oil for pilot control circuits and system hydraulic oil replenishment
Built-in load-sensing power regulator automatically adjusts total pump flow output according to real-time load changes, preventing engine stall during heavy digging and loading operations
Compact tandem integrated layout perfectly fits the limited hydraulic compartment space of U35-4 and KX033-4 compact excavators

4. Product Advantages

Exact 1:1 OEM outer casting dimensions, supporting plug-and-play installation without modification to hydraulic pipelines or chassis mounting structure
Every finished pump undergoes comprehensive hydraulic bench inspection covering pressure stability, flow consistency and internal leakage testing before shipment
Complete maintenance spare parts are held in stock, including overhaul seal kits, piston assemblies, swash plates and valve plates for separate component replacement during repair work
Multiple supersession part numbers fit two machine models, simplifying spare part ordering and inventory management for suppliers and repair workshops

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 prevent collision and moisture damage 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 all five RC788 series part numbers mutually interchangeable?
A: Yes, RC788-61112, RC788-61113, RC788-61122, RC788-61123 and RC788-61124 are iterative upgraded part numbers for the same Nachi PVD-0B-28P pump assembly, fully cross-replaceable for U35-4 and KX033-4.
Q: Can this pump install directly on both U35-4 and KX033-4?
A: Yes, unified mounting sizing and factory-calibrated hydraulic parameters enable direct bolt-on fitting for both models with no extra adjustment or modification required.
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.
