316-5977 Outer Valve Spring Fits Caterpillar 3516C

316-5977 Inner Valve Spring – Precision Fit for Caterpillar 3516C Engines

The 316-5977 inner valve spring is a critical component installed inside the outer valve spring (part number 316-5976) within the cylinder head assembly of the Caterpillar 3516C diesel engine. Designed to enhance valve closing force and vibration resistance, it works in tandem with the outer spring to maintain optimal valve timing and engine efficiency under high-load conditions.

Manufactured with the same high-grade spring steel and precision craftsmanship as its outer counterpart, the 316-5977 inner spring ensures long-lasting durability, reliable performance, and reduced maintenance requirements. It is especially suitable for use in demanding applications such as marine propulsion, power generation, and mining operations.
