Fully compatible mini excavator models: Yanmar VIO70-2, VIO70-3A, VIO75-C
Unified mounting flange, input shaft spline and hydraulic port layout supports direct cross replacement for all three machine models
2. Core Technical Specifications
Structure type: Integrated tandem variable axial piston main pump with built-in pilot charge gear pump
Displacement configuration engineered to match factory hydraulic system design for VIO70 / VIO75 series mid-size mini excavator platform
Rated continuous working pressure complies with original system parameters, with preset maximum relief pressure for reliable overload protection
Operating rotation speed range precisely calibrated to match rated output speed of the original engine equipped on these machines
Mounting bolt layout, shaft dimension and oil port orientation strictly follow OEM dimensional drawing standards
Pump housing is made of high-strength ductile iron; internal pistons, valve plates and friction wear components adopt quenched alloy steel to improve durability and extend total service life
3. Internal Structure & Functional Introduction
Dual main piston pumps generate 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 responding to real-time load changes, preventing engine stall during heavy digging and loading operations
Compact tandem layout fits neatly inside the designated hydraulic compartment of VIO70 and VIO75 series excavators
4. Product Advantages
Exact 1:1 OEM outer casting dimensions, enabling 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 held in stock, including overhaul seal kits, piston assemblies, swash plates and valve plates for separate component replacement during repair work
Single pump model fits three machine variants, streamlining 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: Can this AP2D36LV1RS7 pump install directly on VIO70-2, VIO70-3A and VIO75-C?
A: Yes, unified mounting sizing and factory-calibrated hydraulic settings support direct bolt-on fitting for all three listed models with no extra adjustment or modification required.
Q: What is the connection between AP2D36LV1RS7 and the listed OEM numbers?
A: AP2D36LV1RS7 is the official Uchida Rexroth pump model designation, while 172478-73100, 172478-73101 and 172989-73100 are exclusive OEM part numbers assigned by Yanmar for this complete pump assembly.
Q: Are individual repair spare parts available for this hydraulic pump?
