Exhaust Manifold 288-6985 for CAT Wheeled Excavator M316D M318D M322D

For CAT wheeled excavator owners and service providers maintaining M316D, M318D, and M322D models, the exhaust manifold represents a critical component where material quality and manufacturing precision directly impact machine performance. Our replacement exhaust manifold (Part 288-6985) delivers OEM-compliant specifications through advanced casting technologies specifically engineered for heavy equipment applications.

Material Excellence for Demanding Conditions
Manufactured from high-nickel ductile iron (Grade D-5S), this exhaust manifold demonstrates exceptional performance characteristics:

• Maintains 450 MPa tensile strength at continuous operating temperatures of 750°C

• Superior thermal fatigue resistance withstanding 1200+ thermal cycles

• Enhanced oxidation resistance through 2.5% nickel content

• Optimal creep resistance under sustained high exhaust temperatures
  The material's vermicular graphite structure provides superior thermal conductivity while maintaining excellent vibration damping properties essential for excavator applications.

Precision Manufacturing Process
Our production methodology ensures consistent quality and perfect fitment:

• High-pressure molded sand casting with resin-bonded cores

• Computer-controlled solidification simulation preventing internal defects

• Five-axis CNC machining of mounting surfaces (flatness within 0.08mm)

• Robotic surface finishing ensuring optimal exhaust gas flow characteristics

• Coordinate measuring machine validation of all critical dimensions

Performance and Reliability Features
Engineered specifically for CAT excavator platforms:

• Optimized runner geometry reducing exhaust backpressure by 18%

• Reinforced turbo flange preventing warping under thermal cycling

• Strategic ribbing pattern controlling thermal expansion stresses

• Precision-machined sealing surfaces ensuring perfect cylinder head contact

• Complete compatibility with factory mounting hardware and gaskets

Quality Assurance Protocol
Each manifold undergoes rigorous validation:

• Hydrostatic pressure testing at 4.8 bar for 20 minutes

• Thermal cycling between 100-800°C for 200 cycles

• Dimensional verification using laser scanning technology

• Magnetic particle inspection for surface defect detection

• Material composition analysis through spectrographic testing
