This is a high-quality main valve seal kit designed to ensure proper sealing and prevent hydraulic fluid leaks within the main control valve assembly of Volvo excavators. Manufactured to meet stringent OEM quality standards, it provides reliable sealing performance superior to worn or degraded seals. Operators may notice external hydraulic fluid leaks around the main valve, sluggish hydraulic functions, or a drop in hydraulic system pressure when these seals begin to fail.

Failure Symptoms

The first indication of failing main valve seals is often visible hydraulic fluid leakage from the valve body. If ignored, this leakage can lead to a significant drop in hydraulic system pressure and performance, making machine operations slow and inefficient. Continued operation with leaking seals risks contamination of the hydraulic fluid and potential damage to pumps and cylinders.

Installation Tip

Carefully inspect the valve spools and bores for any scoring or damage before installing the new seals. Ensure all seals are properly seated and lubricated with clean hydraulic fluid to prevent tearing during installation.

Service Note

Inspect the hydraulic fluid for contamination and consider replacing the main hydraulic filter element when rebuilding the main control valve.
