FBFXLB00074 — For Volvo Excavator Ec380D Main Valve Seal Kit

This main valve seal kit is designed to replace worn or leaking seals within the primary hydraulic control valve manifold of Volvo excavators. It is manufactured using high-grade elastomers and metals that meet or exceed original equipment specifications, providing superior resistance to pressure and temperature compared to degraded original seals. Operators may observe external hydraulic fluid leaks from the valve body, a spongy or unresponsive main hydraulic function, or a drop in system pressure when this seal kit is needed.

Failure Symptoms

The first indication of failing main valve seals is often external hydraulic fluid leakage from the valve body. If left unaddressed, this can lead to a gradual loss of hydraulic system pressure, resulting in sluggish or weak operation of boom, stick, and bucket functions. Continued operation with leaking seals risks environmental contamination and potential damage to the hydraulic pump due to cavitation.

Installation Tip

Thoroughly clean the valve body and spool bore before installing new seals to prevent contamination. Ensure all seals are correctly oriented and seated properly to avoid immediate leakage upon system pressurization.

Service Note

Inspect the hydraulic control valve spool for scoring or wear, and check the hydraulic fluid for contamination before reassembly.
