Both part numbers share identical external mounting structure and internal hydraulic configuration, supporting mutual replacement across all three 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 matches the original hydraulic system design of the SV100 series excavator platform
Rated continuous working pressure complies with factory system specifications, with preset maximum relief pressure to deliver reliable overload protection
Operating rotation speed range is precisely calibrated to match the rated speed of the original engine fitted on these machines
Mounting bolt layout, input shaft spline dimension and hydraulic port positioning strictly adhere to OEM dimensional standards
Pump housing is produced from ductile iron; internal pistons, valve plates and wear components use quenched alloy steel to strengthen wear resistance and prolong total service lifespan
3. Internal Structure & Functional Introduction
Main piston pump generates high-pressure hydraulic oil to actuate boom, arm, bucket, travel and swing operational movements
Integrated pilot gear pump supplies steady pressurized oil for pilot control circuits and system makeup oil replenishment
Built-in power adjustment regulator automatically modulates pump flow output in response to load variations, avoiding engine stall during heavy digging operations
Compact integrated layout ensures proper installation inside the dedicated hydraulic compartment of SV100 series excavators
4. Product Advantages
Exact 1:1 OEM outer casting dimensions, allowing plug-and-play installation with no modifications needed to hydraulic piping or chassis mounting structure
Every finished pump completes comprehensive hydraulic bench inspection covering pressure stability, flow consistency 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 repair work
Two 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 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 172499-71200 and 172499-73100 interchangeable with each other? A: Yes, these two part numbers correspond to the same AP2D36LV3RS6-854 pump assembly with matching installation dimensions and internal hydraulic parameters, suitable for cross fitting on all listed Yanmar models.
Q: Can this pump mount directly on SV100, SV100-1 and SV100-1A? A: Yes, unified mounting sizing and factory-calibrated hydraulic settings support direct bolt-on fitting for all three models without extra adjustment or tuning work.
Q: Are separate repair components offered 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.
