High Light C6.4 Excavator Engine Cylinder HeadE320D Upper Cylinder BlockEngine Cylinder Head 297-7644

This C6.4 excavator engine cylinder head, also known as E320D engine upper cylinder block, is a critical engine core casting component designed for CatC6.4 diesel engine and CAT E320D / 323D excavator models. As a high-precision engine upper assembly part, it integrates combustion chambers, valve seats, coolant passages and oil galleries to ensure stable engine power output and efficient heat dissipation. Made of high-strength ductile iron casting with precision-machined sealing surfaces, this C6.4 cylinder head delivers outstanding pressure resistance, thermal stability and sealing performance under heavy-duty working conditions. It perfectly matches OEM specifications for direct replacement during engine overhaul, widely used in construction machinery repair shops, fleet maintenance and global aftermarket parts wholesale.

Characteristics

  • OEM Exact Casting & Machining: 100% match original dimensions, hole positions and thread specs for bolt-on installation.
  • High-strength Ductile Iron Material: Excellent tensile strength, crack resistance and thermal fatigue resistance.
  • Precision 24-valve Seats & Guides: CNC-machined valve seats (30° intake / 45° exhaust) for perfect valve sealing.
  • Optimized Coolant & Oil Passages: Smooth internal galleries ensure efficient heat dissipation and lubrication.
  • Reinforced Combustion Chamber Design: Thickened wall structure resists high combustion pressure and thermal shock.
  • Ultra-flat Sealing Surface: Precision grinding ≤0.05mm flatness eliminates leakage risk.
  • Anti-corrosion & Anti-rust Treatment: Surface shot blasting + anti-rust coating for long service life.

Production Process

  • Raw Material Inspection: High-grade low-carbon ductile iron with certified spheroidization rate.
  • Precision Sand Casting: Resin-bonded sand mold for smooth surface and accurate geometry.
  • Post-casting Stress Relief Annealing: 550–600°C heat treatment to eliminate internal stress.
  • 5-axis CNC Machining: Milling, drilling and tapping for all ports, seats and bolt holes.
  • Valve Seat & Guide Installation: Cryogenic interference fit and precision reaming.
  • High-pressure Hydraulic Testing: 180 bar pressure hold for 3 minutes to check leakage.
  • Surface Treatment & Final Inspection: Shot blasting, anti-rust coating and dimensional verification.
  • Anti-rust Packaging: Sealed plastic bag + wooden crate for international shipping.
