Гидронасос 487-6207 4876207 для мини-экскаватора Caterpillar 301.7CR 301.8 302CR

1. Product Core Overview
Component Type: Variable Displacement Axial Piston Pump.

Function: The primary power source for the mini excavator's hydraulic system, providing flow to the boom, bucket, blade, and travel motors.

Compact Efficiency: Specifically designed for the Next Generation CAT mini excavators, where high power density is required within a very confined engine compartment.

2. OEM Compatibility and Fitment
Part Numbers: 100% direct replacement for Caterpillar OEM part numbers 487-6207 and 4876207.

Machine Compatibility: Specifically engineered for the "Next Gen" series:

CAT 301.7CR

CAT 301.8

CAT 302CR

Seamless Integration: Features the exact mounting flange, input shaft spline, and hydraulic port layout as the factory-installed unit, ensuring no modifications are needed during installation.

3. Technical Performance Features
Load-Sensing Technology: Calibrated to work with the machine's load-sensing hydraulic valve, providing flow only when needed to reduce fuel consumption and engine strain.

Operating Pressure: Rated to meet CAT's high-pressure specifications for maximum breakout force and lifting capacity in the 1.7 to 2.0-ton class.

Precision Internal Components: Built with high-grade alloy cylinder blocks and precision-ground pistons to ensure high volumetric efficiency and minimal heat generation.

4. Why Partner With a 13-Year Industry Expert?
Technical Precision: We understand the specific flow requirements of the 487-6207 series, ensuring our pumps restore the factory speed and "feel" of your machine.

Quality Assurance: Every pump undergoes a comprehensive bench test—checking for pressure stability, flow accuracy, and zero leakage—before it is cleared for international shipping.

Factory-Direct Pricing: Benefit from a 13-year optimized supply chain that offers competitive wholesale rates compared to local dealer retail prices.

Global Logistics: Shipped in reinforced, vibration-dampening packaging via DHL, FedEx, or UPS, typically arriving in 3 to 7 business days.

5. Essential Installation Protocol
Case Priming (Critical): You must fill the pump housing with clean, fresh hydraulic oil through the highest drain port before starting the engine. Running the pump "dry" even for a few seconds will cause immediate internal damage.

Hydraulic System Flushing: If the previous pump failed due to internal contamination (metal particles), the entire system—including the tank and lines—must be flushed to prevent damaging the new unit.

Filter Replacement: Always install a new high-quality hydraulic return filter and suction strainer during the pump replacement process.

6. Ordering and Support
Fitment Verification: To ensure 100% accuracy, please provide your machine Serial Number (e.g., Prefix JH7, LBB, or GBB) when inquiring.
