YYBXLB00071 For Volvo Ec360 Main Pump Seal Kit — Volvo EC360

This is a seal kit specifically designed for the main hydraulic pump on Volvo EC360 excavators, ensuring a tight seal to prevent hydraulic fluid leaks. Manufactured with high-quality elastomers and metals, it maintains pressure and prevents contamination, unlike a worn or damaged seal. Operators may notice external hydraulic fluid leaks around the pump housing, a drop in hydraulic pressure, or increased noise from the pump when this seal kit begins to fail.

Failure Symptoms

The first sign of a failing seal kit is typically visible hydraulic fluid leakage from the main pump housing. If left unaddressed, the leaks will worsen, potentially leading to a significant loss of hydraulic fluid and pressure. This can result in reduced equipment performance and, in severe cases, pump cavitation due to insufficient fluid.

Installation Tip

Carefully clean the pump housing and shaft surfaces before installing new seals to ensure a proper seal. Avoid using sharp tools that could scratch or damage the sealing surfaces.

Service Note

Inspect the hydraulic pump shaft for scoring or wear, and check the hydraulic fluid level and condition when replacing the seal kit.
