C3966164 XCMG GR2605 motor grader crankcase ventilation part

Technical Parameters

• Part Number: C3966164 (3966164)
• Brand: DCEC Cummins (adapted to the original specification of XCMG Grader GR2605)
• Type: Crankcase Ventilation Part (Crankcase Breather, Ventilation Pipe Assembly)
• Material: The shell is made of high-quality aluminum alloy (anodized), the seals are nitrile rubber (NBR), and the ventilation pipe is oil-resistant rubber pipe, with good oil resistance, high and low temperature resistance, anti-aging and impact resistance
• Fit Model: XCMG Grader GR2605 (equipped with Cummins QSB6.7 engine, the rated power of the engine is 194kW/2200rpm, displacement 24L)
• Structure: Integrated assembly structure, including aluminum alloy ventilation shell, oil-resistant ventilation hose, nitrile rubber sealing gasket and fixing clip. The shell is equipped with a filter structure to filter engine oil impurities in blow-by gas. Both ends of the interface are equipped with sealing grooves, which are adapted to the crankcase interface and intake system interface of XCMG GR2605 engine, with precise installation and positioning.
• Key Dimensions: The length of the ventilation hose is 180mm, the outer diameter is φ30mm, and the inner diameter is φ22mm; the length of the aluminum alloy shell is 85mm, the width is 50mm, the height is 40mm, and the interface thread specification is M20×1.5 (precisely adapted to the installation size of XCMG GR2605 engine)
• Surface Treatment: The aluminum alloy shell is anodized, and the anti-rust grade reaches 48 hours of salt spray test without rust; the surface of the ventilation hose is oil-resistant treated, with a temperature resistance range of -40℃~120℃, which can withstand corrosion of engine oil vapor
• Installation Method: Bolt fixing + hose clamp connection. Fix one end of the shell to the crankcase ventilation port of XCMG GR2605 engine with bolts, connect the other end to the intake system interface with a ventilation hose, and fasten it with a clamp to ensure tight sealing. Check the interface size during installation to avoid air leakage.
• Cross Reference: 3901237, 4932303, C3966165 (interchangeable, all adapted to XCMG Grader GR2605 and the equipped Cummins QSB6.7 engine)
• Weight: Approximately 0.35kg per set (including shell, hose, seals and fixing clips)
• Applicable Parts: Between the crankcase and intake system of XCMG Grader GR2605 engine, used to connect the crankcase ventilation port and intake manifold to realize the recovery and reuse of crankcase blow-by gas

Application Scenarios

• Fit Model: XCMG Grader GR2605 (exclusive adaptation, precisely matching the engine interface and installation size of this model, perfectly fitting the pipeline layout of the machine body)
• 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
• 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., can withstand dust and engine oil vapor corrosion, prevent ventilation blockage, and ensure smooth ventilation
• Location: At the crankcase ventilation port on the side of the engine block of XCMG GR2605 grader, one end is connected to the crankcase, and the other end is connected to the intake system, fixed according to the pipeline layout of the machine body, closely fitting with the engine and the machine body bracket, without affecting the operation of other components of the grader
• Functions: Discharge the blow-by gas (engine oil vapor and combustible mixture) in the crankcase of XCMG GR2605 engine, introduce it into the intake system for re-combustion, avoid direct emission of blow-by gas causing pollution; maintain the pressure balance inside and outside the crankcase, prevent engine oil from leaking from oil seals and interfaces due to excessive pressure; filter engine oil impurities in blow-by gas, reduce engine carbon deposition, and protect core components such as cylinders and pistons; isolate external dust and moisture from entering the crankcase, avoid engine oil deterioration, extend the service life of XCMG GR2605 engine, and reduce the risk of grader operation shutdown failure.
