2064127 Spring-Valve — Cat 312B l 312C

This is a valve spring designed to provide the necessary return force for valve operation within the hydraulic system. Manufactured to precise specifications, it ensures consistent performance and durability, outperforming worn or fatigued springs. Operators may notice symptoms such as erratic hydraulic control, slow response times, or a loss of system pressure when this valve spring begins to fail.

Installation & Application Notes

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A weakened valve spring may initially cause a slight delay in hydraulic function response or a minor drop in operating pressure. If left unaddressed, the valve may not close properly, leading to loss of hydraulic holding power or uncontrolled movement. This can compromise the safety and efficiency of machine operations.

Installation Tip

Ensure the valve spool is clean and free of burrs before installing the new spring to prevent binding. Avoid stretching the spring during installation, as this can permanently weaken its return force.

Service Note

When replacing valve springs, it is also prudent to inspect the valve spool and bore for wear and to check the condition of any associated seals.
