Product details

1. Applicable Models

• Caterpillar 365C: A large-scale excavator designed for heavy-duty operations in mining and earthmoving projects.

• Caterpillar 374D: An upgraded model with higher power and efficiency, commonly used in large-scale infrastructure projects.

2. Hydraulic Pump Model Breakdown

A11VO260

• Type: Axial piston variable-displacement pump (swashplate design).

• Displacement: 260 cm³/rev (per revolution).

• Features:

• High-pressure, large-flow design for heavy-duty applications.

• Variable displacement control adjusts output based on load, optimizing energy consumption.

• Used in main pump systems to power travel, swing, boom, and bucket operations.

A20VLO260

• Type: Load-sensing variable-displacement pump (with pressure compensation).

• Displacement: 260 cm³/rev.

• Features:

• Load-sensing control automatically adjusts output pressure and flow based on system demand.

• Energy-efficient operation reduces waste.

• Ideal for precise hydraulic control (e.g., swing, boom, and attachment movements).

4. Core Functions

• Power Output: Supplies hydraulic power for excavator movements, including travel, swing, boom lifting, and bucket digging.

• Energy Optimization:

• A11VO260 reduces energy waste through variable displacement.

• A20VLO260 further enhances efficiency via load-sensing technology.

• Reliability: Designed for harsh conditions (e.g., mining, extreme temperatures).

5. Common Failures & Maintenance

• Failure Symptoms:

• Pump leakage (seal degradation).

• Unstable pressure (variable mechanism issues).

• Abnormal noise (bearing or piston wear).

• Maintenance Tips:

• Replace hydraulic oil and filters regularly (every 2,000 hours).

• Check pump mounting bolt tightness.

• Avoid prolonged overloading.
