Product Specifications

Compatible Applications

Designed for compatible:

Excavator Models:
E320B • E320C

Engine Models:
S6K • 3066

Compatibility may vary according to machine production year, engine version and serial number. We recommend verifying the original part number, engine model and cylinder head configuration before ordering.

Cylinder Head Function

The cylinder head is a critical component of the diesel engine. Mounted above the cylinder block, it helps form the combustion chambers and houses important valve-train components.

Its primary functions include:

Combustion Chamber Sealing • Intake Air Management • Exhaust Gas Flow • Valve Support • Cooling Passage Integration • Engine Compression Management

A correctly manufactured and installed cylinder head is essential for maintaining proper compression, combustion efficiency and overall engine performance.

Main Components & Structure

Depending on the supplied configuration, the cylinder head assembly may include or support components such as:

Cylinder Head Body • Intake Valves • Exhaust Valves • Valve Springs • Valve Seats • Valve Guides • Sealing Surfaces • Intake & Exhaust Ports

Please confirm whether you require a bare cylinder head or assembled cylinder head before ordering.

Common Replacement Situations

Cylinder head replacement may be required after proper engine diagnosis identifies issues such as:

• Cracked or damaged cylinder head
• Excessive overheating damage
• Warped sealing surface
• Worn valve seats or valve guides
• Poor cylinder compression
• Coolant or combustion gas leakage
• Severe corrosion or internal passage damage
• Major engine overhaul or rebuilding

For best results, the head gasket, cylinder block surface, cooling system, valves and related engine components should also be inspected during installation.
