C3971371 XCMG GR2605 motor grader crankcase ventilation pipe

Technical Parameters

• Part Number: C3971371 (3971371)
• Brand: DCEC Cummins (adapted to the original specification of XCMG Grader GR2605)
• Type: Crankcase Ventilation Pipe (Crankcase Ventilation Hose, Ventilation Hose)
• Material: The main body is oil-resistant nitrile rubber (NBR), the joints at both ends are high-quality carbon steel (surface galvanized), and the pipe body is added with anti-aging and anti-tear additives, which have good oil resistance, high and low temperature resistance, vibration resistance and impact resistance, and are not easy to age or crack.
• Fit Model: XCMG Grader GR2605 (equipped with Cummins QSB6.7 engine, the rated power of the engine is 194kW/2200rpm, displacement 24L)
• Structure: Integrated hose structure, the pipe body is flexible design, both ends are equipped with integrally formed carbon steel joints, the joints are equipped with sealing grooves, which can be matched with sealing gaskets to enhance sealing performance. The pipe body has no joints or splicing, good flexibility, and can adapt to the installation angle requirements of the pipeline layout of XCMG GR2605 body.
• Key Dimensions: The length of the pipe body is 320mm, the outer diameter is φ32mm, and the inner diameter is φ24mm; the length of the joints at both ends is 25mm, and the outer diameter of the interface is φ32mm, which is adapted to the interface size of the crankcase ventilation part and the intake system of XCMG GR2605 engine, with precise installation gap.
• Surface Treatment: The surface of the pipe body is oil-resistant and anti-fouling treated, with no obvious scratches; the surface of the carbon steel joint is hot-dip galvanized for anti-rust treatment, and the anti-rust grade reaches 48 hours of salt spray test without rust, which can withstand corrosion of engine oil vapor and dust in the operating environment.
• Installation Method: Clamp fastening connection. Insert the joints at both ends into the crankcase ventilation part interface and the intake system interface of XCMG GR2605 engine respectively, and fasten them with special pipe clamps to ensure tight sealing. Adjust the angle of the pipe body during installation to avoid excessive bending and prevent pipe body damage and air leakage.
• Cross Reference: 3901238, 4932304, C3971372 (interchangeable, all adapted to XCMG Grader GR2605 and the equipped Cummins QSB6.7 engine)
• Weight: Approximately 0.18kg per piece (including joints at both ends, slightly different according to actual size)
• Applicable Parts: Between the crankcase ventilation part and the intake manifold of XCMG Grader GR2605 engine, used to connect the two and transmit crankcase blow-by gas, which is the core connecting pipeline of the ventilation system.

Application Scenarios

• Fit Model: XCMG Grader GR2605 (exclusive adaptation, precisely matching the engine interface size and body pipeline layout of this model, perfectly fitting with the crankcase ventilation part and intake system, no installation interference)
• Construction Machinery Scenarios: Various operating scenarios of XCMG GR2605 grader, including mine site leveling, highway infrastructure leveling, farmland renovation, factory site finishing, etc., adapting to the high-frequency operation and continuous operation needs of the grader, and can adapt to the pipeline deformation caused by body vibration.
• Conditions: Suitable for the common harsh working conditions of XCMG GR2605 grader, including high temperature and high humidity, high altitude and cold, dusty mine sites, frequent starts and stops, continuous heavy load operations, etc. The pipe body can withstand high and low temperature cycles of -40℃~120℃, resist corrosion of engine oil vapor, not easy to age and crack, and prevent ventilation blockage or air leakage.
• Location: On the side of the engine block of XCMG GR2605 grader, between the crankcase ventilation part and the intake manifold, fixed according to the body pipeline layout, the pipe body naturally fits the body bracket, avoiding interference with other moving parts and not affecting the normal operation of the grader.
• Functions: Connect the crankcase ventilation part and the intake system of XCMG GR2605 engine, stably transmit the blow-by gas in the crankcase, ensure that the blow-by gas smoothly enters the intake system for re-combustion, and reduce air pollution; buffer the impact of engine and body vibration on the pipeline, compensate for pipeline installation deviation, and avoid pipe body damage; excellent sealing performance, prevent blow-by gas leakage, avoid engine oil waste and engine carbon deposition; isolate external dust and moisture from entering the ventilation system, protect core engine components, extend the service life of XCMG GR2605 engine and ventilation system, and reduce the risk of operation shutdown failure.
