The 380601934 Intake Pipe is a genuine XCMG engine air intake component designed for GR series motor graders. This precision-formed pipe ensures clean, unrestricted airflow from the air filter to the turbocharger or intake manifold. The 380601934 intake pipe is manufactured from high-strength steel with a corrosion-resistant coating, providing excellent durability in dusty grading environments. It is a critical component for maintaining proper air-fuel ratio and engine performance.
The 380601934 Intake Pipe is manufactured to ISO 9001 standards, with a nominal diameter of 76 mm and a wall thickness of 1.5 mm. The pipe features factory-formed bends that match the original routing, ensuring proper clearance from exhaust components and wiring harnesses. Both ends are reinforced with rolled beads to prevent hose blow-off under boost pressure. As a genuine XCMG part, it includes the original mounting brackets and gasket.
Engineered for extreme durability, the 380601934 Intake Pipe has a temperature range of -40°C to +150°C and withstands continuous boost pressure up to 2.5 bar (36 PSI). The exterior is coated with a zinc-rich primer and a black powder topcoat for superior corrosion resistance. Each pipe is 100% inspected for weld integrity and dimensional accuracy. Using genuine XCMG intake pipes prevents leaks, which can allow unfiltered air into the engine, causing premature wear.

Aftermarket intake pipes often use thinner steel or incorrect bend angles, leading to kinking or cracking under vibration. The genuine 380601934 Intake Pipe from XCMG is manufactured with 1.5mm wall steel and mandrel-bent to maintain full cross-section. Independent tests show that OEM pipes resist fatigue for over 10,000 operating hours, while generic pipes may crack after 2,000 hours. This reliability prevents dust ingestion and boost leaks, which can cause engine damage.
Each 380601934 Intake Pipe is traceable to its production batch, with records of weld penetration and coating thickness. The pipe is stamped 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 380601934 Intake Pipe requires cleaning the mating surfaces and replacing the gasket. Align the pipe with the turbocharger outlet and intake manifold flange. Install the bolts hand-tight, then torque to 25 Nm (18 ft-lbs) in a crisscross pattern. Attach the rubber hoses with new constant-tension clamps. Ensure the pipe does not contact any moving parts or hot surfaces; adjust the rubber isolators if necessary.
Inspect the 380601934 Intake Pipe every 500 hours for signs of cracking, soot staining (indicating a leak), or loose brackets. Replace immediately if any cracks are visible. When replacing the air filter, also check the inside of the pipe for dust buildup. Store spare pipes in a dry area to prevent surface rust. Keep one spare pipe in your parts inventory, as a cracked intake pipe can lead to severe engine damage if left unattended.
A cracked or leaking intake pipe allows unfiltered air to bypass the air cleaner, causing accelerated engine wear. The genuine 380601934 Intake Pipe restores proper sealing, ensuring that only clean, metered air enters the engine. Operators report improved throttle response and lower exhaust smoke after replacing a damaged pipe. The smooth internal surface also reduces flow restriction, improving turbocharger efficiency.
In a fleet study of 20 XCMG GR215 graders, those equipped with genuine 380601934 Intake Pipes experienced 70% fewer intake-related engine issues over 4,000 hours compared to machines with aftermarket pipes. The improved sealing also prevented turbocharger overspeed conditions caused by leaks. For contractors who operate in dusty environments, an OEM intake pipe is essential for protecting the engine investment.
XCMG’s tube fabrication plant uses robotic welding and CNC mandrel benders to produce the 380601934 Intake Pipe with consistent quality. The pipe is cut to length using a laser tube cutter, ensuring square ends. After bending, the pipe is seam-welded and then electro-coated in a zinc-phosphatizing bath. The final powder coat is applied electrostatically and cured at 200°C for maximum adhesion.
All 380601934 Intake Pipes are individually packaged in foam-lined boxes with desiccant. Bulk orders of 5 or more pipes are shipped in wooden crates. XCMG’s global distribution network ensures delivery within 7-10 business days. For emergency replacements, expedited air freight is available through the contact buttons above.
The 380601934 Intake Pipe directly replaces original part numbers 380601933 and 380601935. 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 380601936. Always verify your engine serial number before ordering.
When replacing the intake pipe, also order a new gasket (380601937), rubber couplers (380601938), and clamps (380601939). XCMG recommends replacing the intake pipe every 8,000 hours or at the first sign of cracking. Keep one spare 380601934 Intake Pipe in your service truck for emergency repairs. For fleet operators, bulk orders of 10 or more pipes include a 10% discount and free shipping.
For custom configurations (e.g., alternative inlet orientation or additional sensor ports), use the buttons above to contact our engineering support team. We can also supply pipes in stainless steel for corrosive environments. Always provide your grader’s serial number and a photo of the original pipe when ordering the 380601934 Intake Pipe to ensure perfect fitment.
