YYBXLB00067 For Volvo Ec290 Main Pump Seal Kit — Volvo EC290

This is a main pump seal kit specifically designed for Volvo excavators, containing all necessary seals and O-rings to prevent hydraulic fluid leaks from the main hydraulic pump. Manufactured to meet stringent OEM quality standards, these seals offer superior resistance to heat, pressure, and wear compared to degraded or damaged original seals. Operators may notice external hydraulic fluid leaks around the pump housing, a gradual loss of hydraulic pressure, or increased noise from the pump when the seals begin to fail.

Failure Symptoms

The first sign of failing main pump seals is typically visible external hydraulic fluid leakage around the pump housing. If left unaddressed, this leakage can lead to a gradual loss of hydraulic pressure and performance, potentially causing overheating of the hydraulic system. The primary risk is reduced operational efficiency and potential damage to the pump or other hydraulic components due to low fluid levels or contamination.

Installation Tip

Carefully clean all sealing surfaces on the pump housing and shaft before installing the new seals to ensure a proper seal and prevent damage. Avoid using sharp tools when removing old seals, as this can easily scratch the mating surfaces and compromise the new seal's integrity.

Service Note

When replacing the main pump seals, it is advisable to inspect the hydraulic fluid for contamination and check the condition of the hydraulic filter.
