172456-73100 172956-73100 172173-73100 AP2D9LV1RS7 Main Hydraulic Pump for Yanmar VIO20 VIO20-2 VIO20-3 Mini Excavator (Point-by-Point Layout)
1. OEM Part Number & Machine Compatibility
Original pump model: AP2D9LV1RS7 variable displacement piston pump assembly
Yanmar OEM part numbers: 172456-73100, 172956-73100, 172173-73100
Fully compatible mini excavator models: Yanmar VIO20, VIO20-2, VIO20-3
All three listed part numbers feature identical external mounting structure and internal hydraulic setup, allowing mutual replacement across these machine generations
2. Core Technical Specifications
Structure type: Integrated assembly of variable axial piston main pump and built-in pilot charge gear pump
Main pump displacement is matched to the original hydraulic system design of the VIO20 ultra-small excavator platform
Rated continuous working pressure follows factory system specifications, with preset maximum relief pressure to provide overload protection
Operating rotation speed range is precisely calibrated to match the rated speed of the original engine fitted on these excavators
Mounting bolt layout, input shaft spline size and hydraulic port positioning strictly comply with OEM dimensional standards
Pump housing is manufactured from ductile iron; internal pistons, valve plates and wear components use quenched alloy steel to boost wear resistance and extend operational lifespan
3. Internal Structure & Functional Introduction
Main piston pump produces high-pressure hydraulic oil to power boom, arm, bucket, travel and swing movements
Integrated pilot gear pump delivers steady pressurized oil for pilot control circuits and system makeup oil replenishment
Built-in power adjustment regulator modulates pump flow output automatically in response to load changes, preventing engine stall during heavy digging operations
Compact integrated design conserves installation space within the confined hydraulic compartment of micro mini excavators
4. Product Advantages
Exact 1:1 OEM outer casting dimensions, enabling plug-and-play installation with no alterations required to hydraulic piping or chassis mounting structure
Every finished unit undergoes full hydraulic bench inspection covering pressure stability, flow uniformity and internal leakage testing prior to 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 repair work
Three interchangeable part numbers fit three machine variants, streamlining inventory planning for spare part suppliers and repair service shops
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 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: Can 172456-73100, 172956-73100 and 172173-73100 replace one another?
A: Yes, all three part numbers correspond to the same AP2D9LV1RS7 pump assembly with matching installation dimensions and internal hydraulic parameters, suitable for cross fitting on all applicable Yanmar models.
Q: Is direct installation possible on VIO20, VIO20-2 and VIO20-3?
A: Yes, unified mounting sizing and factory-calibrated hydraulic settings support direct bolt-on fitting for all three models with no additional modification or tuning needed.
Q: Are separate repair components 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.
