• 226-5611 2265611 Muffler Excavator Engine Parts Fitting For 973C

• Specification

• Function

1.Regulatory Compliance: Meets strict noise limits for construction sites (e.g., 85 dB(A) at operator position, per OSHA standards), avoiding fines or project delays.

2.Engine Efficiency: By controlling backpressure, it preserves the D6R’s torque output—critical for heavy tasks like grading, pushing, or excavating—while maintaining fuel economy.

3.Durability in Harsh Environments: Resists corrosion from moisture, dust, and diesel exhaust byproducts (e.g., soot), ensuring consistent performance in rain, mud, or dusty mining sites.

4.Low Maintenance: Simple design with no moving parts reduces the need for frequent repairs; only periodic inspections (for cracks or blockages) are required.
