4360520 Spring-Valve — Cat 323-D3 Engine: C7

This is a high-quality valve spring designed to maintain precise control within the hydraulic system of Caterpillar equipment. Manufactured to meet stringent OEM standards, it ensures consistent performance and durability compared to a worn spring that may lose tension. Operators may notice sluggish hydraulic response or a loss of lifting/actuation power when this spring begins to fail.

Failure Symptoms

A failing valve spring may initially cause a slight delay in hydraulic function or a reduction in system pressure. If left unaddressed, the spring's reduced tension can lead to inconsistent valve operation and potential leakage, compromising the overall efficiency of the hydraulic system.

Installation Tip

Ensure the valve bore is clean and free of debris before installing the new spring to prevent damage. Avoid forcing the spring into place, as this can cause misalignment and premature failure.

Service Note

Inspect the associated valve spool and bore for wear or scoring when replacing the valve spring.
