This is a valve spring designed to control the precise movement of hydraulic fluid within the valve system of CAT equipment. It is manufactured to meet stringent OEM standards, ensuring superior durability and performance compared to a worn or fatigued spring that may exhibit reduced tension or breakage. Operators may notice erratic hydraulic control, slow or unresponsive implement movements, or a loss of system pressure when this spring begins to fail.
Always verify with serial number before ordering.

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.
Initial signs of a failing valve spring may include slight sluggishness in hydraulic functions or inconsistent operation. If ignored, the spring's reduced tension can lead to a gradual loss of hydraulic control precision and potential leakage. Continued operation with a weakened spring risks improper valve seating, affecting overall system performance and potentially causing damage to other hydraulic components.
Ensure the valve bore is clean and free of debris before installing the new spring, as any foreign material can impede proper seating. Avoid over-compressing the spring during installation, as this can lead to premature fatigue and failure.
Inspect the associated valve spool and bore for wear or damage when replacing this spring.
