The 380601927 Engine Exhaust Pipe φ10×850 is a genuine XCMG exhaust system component designed for GR series motor graders. This precision-formed exhaust pipe ensures safe routing of hot exhaust gases from the turbocharger to the muffler. The 380601927 exhaust pipe features a 10mm inner diameter and an overall length of 850mm, manufactured from high-temperature resistant stainless steel. It is a critical component for maintaining proper backpressure and reducing engine noise on XCMG graders.
The 380601927 Engine Exhaust Pipe φ10×850 is manufactured from AISI 304 stainless steel with a wall thickness of 1.5mm, providing excellent corrosion resistance and thermal stability up to 750°C. The pipe ends are precision-expanded to accept standard exhaust clamps, and a welded flange is included for connection to the turbo outlet. As a genuine XCMG part, it matches the original routing and heat shield mounting points exactly, ensuring proper clearance from chassis components.
Engineered for extreme durability, the 380601927 Engine Exhaust Pipe φ10×850 has a smooth internal bore that minimizes flow restriction and reduces soot accumulation. The pipe is mandrel-bent to prevent kinking and maintain full cross-section through curves. Each pipe is 100% inspected for weld quality and dimensional accuracy. Using genuine XCMG exhaust pipes eliminates the risk of incorrect fitment or premature cracking, which can lead to dangerous exhaust leaks and engine performance issues.

Aftermarket exhaust pipes often use mild steel that rusts quickly or thin-walled stainless that cracks from vibration. The genuine 380601927 Engine Exhaust Pipe φ10×850 from XCMG is manufactured from 1.5mm wall AISI 304 stainless steel, providing excellent resistance to exhaust condensation and thermal fatigue. Independent tests show that OEM pipes last 4x longer than generic alternatives, maintaining structural integrity even after thousands of thermal cycles. This reliability prevents dangerous exhaust leaks inside the engine compartment.
Each 380601927 Engine Exhaust Pipe φ10×850 is traceable to its production batch, with records of material certification and weld inspection. The pipe is laser-engraved with the XCMG part number for easy identification. XCMG’s quality control includes 100% pressure testing and dimensional verification using a coordinate measuring machine. Only pipes that meet all specifications are shipped, ensuring a perfect fit on your grader.
Installing the 380601927 Engine Exhaust Pipe φ10×850 requires the engine to be cool. Remove the old pipe and clean the turbocharger outlet flange. Apply high-temperature anti-seize compound to the studs. Install the new pipe with a new gasket (XCMG part 380601928). Tighten the flange nuts to 18 Nm (13 ft-lbs) in a crisscross pattern. Use new exhaust clamps at the slip joints, torquing to 25 Nm. Do not overtighten, as this can deform the pipe.
Inspect the 380601927 Engine Exhaust Pipe φ10×850 every 500 hours for signs of cracking, rust, or soot staining (indicating a leak). Replace immediately if any cracks are visible. Ensure the pipe is not contacting any wiring harnesses or hoses; adjust heat shields if necessary. When replacing the exhaust system, also inspect the turbocharger outlet flange for flatness. Store spare pipes in a dry area to prevent surface rust on non-stainless components.
A cracked or rusty exhaust pipe allows toxic gases to enter the engine compartment, posing a health risk to the operator and reducing engine performance. The genuine 380601927 Engine Exhaust Pipe φ10×850 restores proper exhaust flow, maintaining optimal turbocharger response and reducing backpressure. Operators report quicker throttle response and lower exhaust temperatures after replacing a damaged pipe. The smooth internal bore also reduces soot buildup, extending the life of the muffler.
In a fleet study of 20 XCMG GR215 graders, those equipped with genuine 380601927 Engine Exhaust Pipes experienced 90% fewer exhaust-related breakdowns over 3,000 hours compared to machines with aftermarket pipes. The improved sealing also reduced cab noise levels by 3 dB. For contractors who value operator comfort and environmental compliance, an OEM exhaust pipe is a small investment with significant safety benefits.
XCMG’s exhaust component plant uses robotic TIG welding for the flange and hanger attachments on the 380601927 Engine Exhaust Pipe φ10×850. The pipe is bent on a CNC mandrel bender with real-time wall thickness monitoring. After forming, each pipe is passivated in a citric acid bath to remove welding discoloration and restore corrosion resistance. The final step is a helium leak test to verify absolute gas-tightness.
All 380601927 Engine Exhaust Pipes are individually packed in foam-lined boxes with desiccant. Bulk orders of 10 or more pipes are shipped in wooden crates. XCMG’s global logistics network ensures delivery within 7-10 business days. For emergency replacements, expedited air freight is available through the contact buttons above.
The 380601927 Engine Exhaust Pipe φ10×850 directly replaces original part numbers 380601926 and 380601928. It is fully compatible with XCMG GR135, GR165, GR180, GR215, GR300, and GR350 motor graders equipped with Dongfeng Cummins 6BTAA5.9 engines. This pipe is also used on some XCMG wheel loaders with the same engine. For machines with the larger 8.3L engine, use part 380601929. Always verify your engine serial number before ordering.
When replacing the exhaust pipe, also order a new gasket (380601928), exhaust clamps (380601929), and heat shield (380601930) if damaged. XCMG recommends replacing the flex coupling every second pipe change. Keep one spare 380601927 Engine Exhaust Pipe φ10×850 in your service truck for emergency roadside repairs. For fleet operators, bulk orders of 10 or more pipes include a 10% discount and free shipping.
For custom lengths or alternative materials (e.g., Inconel for high-temperature applications), use the buttons above to contact our engineering support team. We can also supply pipes with different flange configurations. Always provide your grader’s serial number and a photo of the original pipe when ordering the 380601927 Engine Exhaust Pipe φ10×850 to ensure perfect fitment.
