미니 굴착기 Caterpillar 304C CR 305D CR용 유압 펌프 KYB PSVL-54CG-13 266-6942 2666942

Product Title:
KYB PSVL-54CG-13 Hydraulic Main Pump for CAT 304C CR 305D CR | Part No. 266-6942 2666942

1. Product Overview
The KYB PSVL-54CG-13 is a high-performance, variable displacement axial piston pump engineered for the heavy-duty cycles of the 4 to 5-ton mini excavator class. As the primary hydraulic power unit for the CAT 304C and 305D series, it provides the precise flow and high-pressure output required for smooth, synchronized movements of the boom, bucket, and travel motors. Its robust design is specifically optimized for "Compact Radius" (CR) machines, ensuring peak power delivery within a confined engine compartment.

3. Why Partner With a 13-Year Industry Expert?

Technical Precision: We specialize in the KYB PSVL series and understand the specific regulator calibrations required for CAT C-series hydraulic systems. Our pumps restore the original responsiveness and speed to your machine.

Rigorous Bench Testing: Every unit undergoes a comprehensive hydraulic test to verify volumetric efficiency, pressure stability, and response times before it is cleared for export.

Direct Factory Value: Benefit from our 13-year optimized supply chain, offering high-quality OEM and Premium replacement options at competitive wholesale prices compared to local retail dealerships.

Global Logistics Expertise: All pumps are secured in reinforced, shock-proof export wooden crates. We offer rapid delivery via DHL, FedEx, or UPS, typically arriving in 3 to 7 business days.

4. Critical Installation & Maintenance Protocol

Case Priming (Mandatory): You must fill the pump housing with clean, fresh hydraulic oil through the highest drain port before starting the engine. Running the pump "dry" will cause immediate and irreversible internal damage to the pistons and bearings.

System Decontamination: If the previous pump suffered a mechanical failure (metal-to-metal contact), you must flush the entire hydraulic tank, lines, and oil cooler. Residual metallic debris is the primary cause of premature failure in replacement pumps.

Filter Mandate: Always install a new high-efficiency hydraulic return filter and suction strainer during the pump replacement to maintain oil cleanliness and protect the precision internal components.

5. Ordering & Professional Support

Fitment Verification: To ensure 100% accuracy, please provide your machine Serial Number (e.g., Prefix FPK or HWZ) or a photo of your existing pump nameplate.
