Application
The 3314A121 Valve Seat is precision-engineered for 4.4-liter and 6.6-liter inline diesel engine platforms, specifically compatible with 1004 and 1006 series power units. This valve seat is extensively utilized across heavy-duty agricultural machinery, construction equipment, material handling systems, and power generation units.
The valve seat serves as the critical sealing surface for exhaust valves, ensuring proper valve-to-seat contact and maintaining combustion chamber integrity during engine operation. It is compatible with naturally aspirated and turbocharged diesel engines, supporting reliable operation in high-demand farming, earthmoving, and industrial power applications.
Technical Specifications
  • Seat Type: Exhaust Valve Seat Insert
  • Compatible Engines: 4.4L and 6.6L diesel engines (1004-4, 1004-4T, 1004-40, 1004-40T, 1006-6, 1006-6T, 1006E-6T, 6.354 series)
  • Outer Diameter: 42.7 mm (1.681 inches)
  • Inner Diameter: 32.8 mm (1.290 inches)
  • Overall Height: 9.5 mm (0.374 inches) - stepped top design
  • Seat Angle: 45 degrees
  • Material Grade: High-grade cast iron or sintered alloy steel with enhanced wear resistance
  • Surface Treatment: Precision-machined seating surface with hardened wear layer
  • Weight: 0.05-0.10 kg (0.11-0.22 lbs) per unit
  • Operating Temperature Range: -40°C to +800°C (continuous exhaust gas exposure)
  • Valve Compatibility: Designed for 37.4 mm head diameter exhaust valves (3142A051 series)
  • Seat Insert Type: Stepped top design for interference fit installation
  • Quantity per Engine: 4 units (4-cylinder engines) or 6 units (6-cylinder engines)
  • Installation Method: Interference press-fit into cylinder head valve seat bore
  • Valve Guide Compatibility: Works in conjunction with 3343J021 exhaust valve guides
Material & Performance Features
The valve seat is manufactured from high-grade cast iron or sintered alloy steel, featuring exceptional wear resistance, thermal conductivity, and dimensional stability under cyclic high-temperature operating conditions. The material composition includes alloying elements such as chromium, nickel, and molybdenum that provide superior resistance to valve seat recession, pitting, and corrosion from combustion byproducts.
The seat undergoes precision machining and grinding operations to achieve tight dimensional tolerances and optimal surface finish on the 45-degree sealing face. This precision ensures effective sealing against high-pressure combustion gases and proper heat transfer from the valve head to the cylinder head cooling system. The stepped top design provides positive location during installation and enhanced heat dissipation characteristics.
The 45-degree seat angle is engineered to match the valve face angle, ensuring maximum contact area and uniform seating pressure distribution. The material exhibits excellent resistance to micro-welding and adhesive wear between the valve face and seat insert, preventing valve seat recession and maintaining compression integrity over extended service intervals.
