Caterpillar Cylinder Head for 3116 & 3126 Engines

Technical Overview
This new cylinder head is engineered for Caterpillar 3116 and 3126 diesel engines. Cast from high-strength alloy and precision-machined, it restores sealing integrity, heat transfer, and airflow across intake/exhaust ports. The head is offered with valves or with springs (see options), ensuring correct valvetrain geometry and reliable performance under continuous-duty conditions in marine and industrial applications.

Detailed Features
OEM-quality casting with reinforced fire-deck and coolant passages for thermal stability. Machined valve seats and guides support consistent compression and reduced oil consumption. Flatness and surface finish are controlled for MLS/composite gaskets. Each head is pressure-tested and inspected for cracks, porosity, and thread integrity. Supplied ready for final assembly with your existing rocker gear and hardware as required.
