381100613 XCMG GR2605 motor grader exhaust hose

381100613 is a genuine XCMG GR2605 motor grader exhaust system original flexible exhaust hose (metal corrugated hose assembly). Installed between the engine exhaust manifold and the muffler/aftertreatment device, it functions as a flexible shock absorber, compensates for thermal expansion, and seals the exhaust system. It isolates high-frequency vibrations, absorbs thermal deformation of the pipes, prevents exhaust gas leakage and cracking of rigid joints, and is suitable for harsh working environments such as high temperatures, dust, and strong impacts on construction sites.

Core Functions and Effects

Vibration Isolation and Fatigue Resistance: The corrugated flexible structure effectively absorbs vibrations generated by engine operation and machine body vibrations, preventing weld cracking and flange loosening at rigid pipe connections due to long-term stress concentration; significantly reducing exhaust system resonance noise.

Thermal Expansion and Contraction Compensation: Withstands high exhaust gas temperatures, allowing for slight axial and lateral expansion and contraction to compensate for changes in pipe length caused by alternating hot and cold temperatures, preventing pipe twisting or breakage.

Exhaust Gas Sealing and Environmental Protection: The flange/clamp sealing structure at both ends, combined with high-temperature resistant gaskets, ensures 100% exhaust gas is discharged through the pipeline, preventing toxic exhaust gases from entering the cab or work area, protecting operator health, and complying with emission regulations.

Installation Tolerance and Aftertreatment Protection: Allows for minor coaxiality deviations during installation, avoiding component damage caused by forced docking; protects precision aftertreatment equipment such as SCR/DPF from direct impact from engine vibration.

Replacement and Maintenance Points

The exhaust system must be stopped and thoroughly cooled (at least 1…) Disconnect the battery negative terminal (for hours) to prevent burns, electric shock, and accidental starting; Clean oil and carbon deposits from the flange surface before disassembly; Remove bolts in a crisscross sequence to avoid uneven stress and deformation of the flange; When installing a new hose, first install the locating pin, then tighten the bolts evenly to the original factory specified torque; Replace with a brand new high-temperature resistant gasket, and never reuse an old gasket; After installation, check that the hose is not twisted, excessively stretched/compressed, or has any interference around it; Start the engine and check for leaks, abnormal noises, and abnormal vibrations under idling and full load conditions; Regular maintenance: Check bolt torque and appearance every 500 hours; Increase the frequency of checks in dusty/high-humidity coastal conditions to prevent corrosion of the mesh sleeve and flange; Replace any damaged parts immediately with original factory parts.
