Failure Symptoms

A failing main valve seal kit often first manifests as a slight decrease in hydraulic system precision or a minor external leak from the control valve. If left unaddressed, internal leaks will worsen, leading to sluggish or jerky operation of hydraulic functions and increased external fluid loss. This can compromise the machine's ability to perform tasks safely and efficiently.

Installation Tip

Thoroughly clean the valve body and all internal components before installing the new seals to prevent contamination. Be extremely careful not to damage the sealing surfaces or the new seals during installation.

Service Note

When replacing the main valve seal kit, inspect the valve spools for scoring and check the hydraulic fluid for contamination.
