4360524 Spring-Valve — Cat 120M 2 2384C

This is a valve spring, a crucial component in an engine's valvetrain responsible for returning the valve to its closed position after actuation by the camshaft. It is manufactured to meet stringent OEM quality standards, providing consistent spring tension and durability compared to weakened or broken springs. Operators may notice engine misfires, loss of power, rough idling, or increased exhaust smoke when a valve spring begins to fail.

Failure Symptoms

The first symptom of a failing valve spring is often an intermittent engine misfire, especially under load or at higher RPMs. If left unaddressed, the spring can weaken further, leading to persistent rough idling, loss of engine power, and potential valve float. Continued operation risks valve-to-piston contact, causing severe internal engine damage.

Installation Tip

Ensure the valve spring retainer and valve stem are properly aligned before assembly to prevent binding or damage to the spring. Always use a torque wrench to tighten cylinder head bolts in the correct sequence and to the specified torque.

Service Note

Inspect the valve seals, valve guides, and valve seats for wear or damage when replacing valve springs.
