21326667 — Cylinder Head Valve Spring 21326667 For Volvo Engine D16 Loader L350F Excavator Ec700Chr Ec700Blc Ec750El Ec750Dl Ec700Chr

This cylinder head valve spring is a crucial component within the engine's valvetrain, responsible for closing the intake and exhaust valves after they have been opened by the camshaft. Manufactured from high-tensile spring steel, it provides the necessary force to ensure rapid and complete valve closure, maintaining engine timing and compression. Operators might notice rough idling, misfires, or a loss of engine power if a valve spring weakens or breaks.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

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 intermittent misfires, particularly under load or at higher RPMs. As the spring degrades further, the misfires can become more frequent, leading to a noticeable loss of engine power and rough running. A completely broken spring will result in a severe loss of compression and a non-operational cylinder.

Installation Tip

Ensure the valve is fully seated and the spring compressor is securely engaged before attempting to compress the spring. Always install valve stem seals before installing the valve spring and retainer.

Service Note

When replacing valve springs, it is essential to inspect the valve seats for wear and ensure the valve guides are within specified tolerances.
