1U1625 Gear Pump-Hydraulic — Cat D6H

This Gear Pump-Hydraulic is the heart of the machine's hydraulic system, generating the necessary flow and pressure to power implements and steering. Manufactured to exacting standards, it provides consistent fluid delivery and durability, unlike worn pumps that can cause system inefficiency and component damage. Operators may notice a significant loss of power, slow or unresponsive hydraulics, and increased system noise when this pump begins to fail.

Failure Symptoms

A failing Gear Pump-Hydraulic will first present as a noticeable reduction in hydraulic system performance, such as slower boom or bucket movements. If ignored, this can lead to a complete loss of hydraulic power, rendering the machine inoperable and potentially causing overheating of the hydraulic fluid. Continued operation with a worn pump can lead to severe damage to other critical hydraulic components.

Installation Tip

Ensure the hydraulic reservoir is clean and the suction line is free of obstructions before installation to prevent immediate damage to the new pump. Do not run the pump dry, even for a moment, as this can cause internal scoring.

Service Note

Clean the hydraulic reservoir, replace the hydraulic filter, and inspect all suction and pressure lines for leaks or damage when installing a new Gear Pump-Hydraulic.
