Product Description
PSVD2-17E 172B04-73100 172B04-73120 172B04-73130 172B04-73110 Main Hydraulic Pump for Yanmar VIO50-6A VIO50-6B VIO50-2A Mini Excavator
1. OEM Part Number & Machine Compatibility
  • Original pump model: KYB PSVD2-17E variable displacement axial piston pump assembly
  • Yanmar OEM part numbers: 172B04-73100, 172B04-73120, 172B04-73130 172B04-73110
  • Fully compatible mini excavator models: Yanmar VIO50-6A, VIO50-6B, VIO50-2A
  • All three listed part numbers share identical external mounting dimensions and internal hydraulic configuration, supporting mutual cross replacement for these machine models
2. Core Technical Specifications
  • Structure type: Integrated unit of variable main piston pump and built-in pilot charge gear pump
  • Main pump displacement: 17 cm³/rev, matched to original ViPPS hydraulic system design of VIO50 series excavator platform
  • Rated continuous working pressure: 24.5 MPa; preset maximum relief pressure provides reliable overload protection for the whole hydraulic system
  • Operating rotation speed range precisely calibrated to match rated speed of original engine equipped on these compact excavators
  • Mounting bolt layout, input shaft spline size and hydraulic port orientation strictly comply with OEM dimensional drawings
  • Pump housing adopts ductile iron material; internal pistons, valve plates and friction components use quenched alloy steel to improve wear resistance and extend service lifespan
3. Internal Structure & Functional Introduction
  • Main piston pump outputs high-pressure hydraulic oil to drive boom, arm, bucket, travel and swing working movements
  • Integrated pilot gear pump supplies stable pressurized oil for pilot control circuits and system hydraulic oil replenishment
  • Built-in power adjustment regulator automatically modulates pump flow output responding to load changes, preventing engine stall during heavy digging operations
  • Compact integrated layout fits neatly inside the limited hydraulic compartment of VIO50 series mini excavators
4. Product Advantages
  • Exact 1:1 OEM outer casting dimensions, enabling plug-and-play installation with no 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
  • Three interchangeable part numbers fit three machine variants, simplifying inventory planning for spare part suppliers and repair service 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 Southeast Asian markets
6. FAQ
  • Q: Are 172B04-73100, 172B04-73120 and 172B04-73130 interchangeable?

    A: Yes, all three part numbers correspond to the same PSVD2-17E pump assembly with matching installation dimensions and internal hydraulic parameters, suitable for cross fitting on VIO50-6A, VIO50-6B and VIO50-2A directly.

  • Q: Can this pump install directly on all three listed Yanmar models?

    A: Yes, unified mounting sizing and factory-calibrated hydraulic settings support direct bolt-on fitting for VIO50-6A, VIO50-6B and VIO50-2A with no extra adjustment 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.
