Application
The 3681E051 and 3681E046 Head Gaskets are precision-engineered cylinder head sealing components specifically designed for 4.4-liter inline diesel engine platforms, compatible with 1104 series power units. These gaskets are extensively utilized across heavy-duty agricultural machinery, construction equipment, generator sets, material handling systems, and industrial power generation units.
The gasket serves as the critical sealing interface between the cylinder head and engine block, maintaining combustion chamber integrity, preventing coolant and oil cross-contamination, and ensuring proper compression sealing. It is compatible with naturally aspirated and turbocharged diesel engines featuring electronic fuel injection systems, supporting reliable operation in high-demand farming, earthmoving, stationary power, and material handling applications.

Material & Performance Features
The head gasket is manufactured utilizing advanced Multi-Layer Steel (MLS) technology featuring 4 layers of precision-embossed stainless steel with elastomeric coatings. This construction provides exceptional resistance to combustion gases, engine coolants, and lubricating oils while maintaining structural integrity under extreme thermal and mechanical loads.
The MLS design incorporates strategically placed rubber-bonded sealing beads around combustion chambers, coolant passages, and oil galleries. These elastomeric coatings ensure micro-sealing of surface imperfections while the steel layers provide the primary structural sealing force. The embossed steel layers create multiple sealing barriers that prevent leakage even under high thermal cycling and pressure fluctuations.
The gasket material exhibits excellent chemical compatibility with modern engine coolants including ethylene glycol-based formulations, as well as synthetic and mineral-based lubricating oils. The stainless steel construction resists corrosion from combustion acids and coolant additives, ensuring long-term durability.
The precision-engineered thickness and embossing patterns provide optimal compression characteristics when installed with proper head bolt torque procedures. The gasket accommodates minor surface irregularities in the cylinder head and block mating surfaces while maintaining positive sealing contact pressure.
