9J5049 Caterpillar Pump Gr Vane 9J5049 — Cat

This is a vane for a hydraulic pump, specifically designed to create a seal against the pump's cam ring to generate hydraulic flow. Manufactured to precise tolerances and durable materials, it ensures efficient operation and longevity within the hydraulic system. Operators may experience a reduction in hydraulic pressure, slower machine functions, or increased pump noise if these vanes are worn or broken.

Failure Symptoms

The initial symptom of worn or damaged vanes is a gradual decrease in the hydraulic system's overall pressure and flow rate. As the condition worsens, machine functions will become noticeably slower and less responsive, and the hydraulic pump may begin to emit an audible whining or grinding noise. Continued operation with compromised vanes can lead to increased heat generation and potential damage to the pump housing and other internal components.

Installation Tip

Ensure the pump housing and rotor slots are meticulously clean before inserting the new vanes to prevent binding or damage. Lightly lubricate the vanes with clean hydraulic oil to aid installation and initial operation.

Service Note

Inspect the pump housing and rotor for wear, and replace the hydraulic filter and fluid.
