JCB JS130 hydraulic pump

The JCB JS130 excavator  uses a Kawasaki axial piston hydraulic pump as the main hydraulic pump. While the exact model might vary depending on the year of your machine and specific configuration, here's some information to help you identify and maintain it

Pump Model

Based on parts suppliers, a common hydraulic pump used in the JCB JS130 is the Kawasaki K3V63 series. This is a variable displacement pump, meaning its flow rate can be adjusted to match the excavator's needs. The specific model number might have additional letters and numbers after the base model (e.g., K3V63DT).

Identification

Refer to your JCB JS130 operator's manual or parts catalog for the exact model number and any other identifying information on the pump itself.

Look for a plate or label on the pump housing that might specify the model number, displacement (ccrev), and other details.

Functions

The hydraulic pump in the JCB JS130 is responsible for converting the engine's mechanical power into high-pressure hydraulic fluid. This fluid is then distributed throughout the excavator's hydraulic system to power various functions like

Arm and bucket movement

Track drive

Blade control (if equipped)

Attachment operation (breakers, augers, etc.)

Maintenance

Regular maintenance of the hydraulic pump is crucial for the excavator's performance and longevity. Here are some key maintenance practices

Oil changes and filter replacement Follow the recommended intervals in your JCB JS130 manual for hydraulic oil and filter changes. Clean oil is vital for proper pump lubrication and preventing wear.

Fluid level checks Regularly check the hydraulic fluid level according to the markings on the reservoir. Low fluid levels can lead to cavitation (formation and collapse of vapor bubbles) and damage the pump.

External inspection Look for leaks, loose connections, or visible damage on the pump housing and surrounding components. Address any issues promptly.

Replacement

If the hydraulic pump needs replacement, consider using a genuine Kawasaki K3V63 series pump or a high-quality equivalent from a reputable manufacturer. Non-genuine replacements can compromise performance, reliability, and safety.

Consult a qualified technician for pump replacement, as it might involve specialized tools and procedures.
