1959097 Pump Gp-Ps — Cat D6N

This is a pilot hydraulic pump assembly, crucial for supplying pressurized fluid to the machine's control systems and power steering. Constructed with precision components and high-quality seals, it ensures consistent and responsive hydraulic power delivery, unlike a worn pump that would result in sluggish controls. Operators may notice a lack of power steering assist, slow implement response, or difficulty in maneuvering the machine when this pump begins to fail.

Failure Symptoms

The first indication of a failing pilot pump is often a slight delay in steering response or a reduction in the sensitivity of pilot controls. If the issue progresses, steering may become noticeably heavy, and implement movements will become slow and unresponsive. Continued operation with a faulty pilot pump can lead to operator fatigue and potential loss of directional control.

Installation Tip

Ensure the hydraulic reservoir is filled to the correct level with the specified hydraulic fluid before starting the pump. Bleed the air from the system thoroughly after installation to prevent cavitation and damage.

Service Note

Inspect the pilot hydraulic filter, reservoir fluid level and condition, and all related hoses and fittings for leaks or blockages.
