The 860159482 Fuel Injector is a genuine XCMG common rail fuel injector designed for GR series motor graders. This precision electro-hydraulic component delivers atomized diesel fuel into the combustion chamber at exact timing and quantity, ensuring optimal power, fuel economy, and emissions. The 860159482 fuel injector is manufactured with multi-hole nozzle technology, a high-speed solenoid valve, and a hardened steel body, offering exceptional durability under high injection pressures (up to 1800 bar). Used as original equipment on XCMG GR2003, GR215, GR300, and GR350 graders powered by XCMG XC6B or XC6D diesel engines, this injector directly replaces worn, clogged, or leaking units, restoring engine performance and reducing smoke. Each injector is 100% flow-tested and certified with a calibration code.
The 860159482 Fuel Injector features a 7-hole nozzle with a 0.18 mm orifice, providing excellent fuel atomization for complete combustion. The solenoid coil resistance is 0.2-0.3 ohms, compatible with Bosch common rail systems. Replacing a failed injector with the genuine 860159482 part eliminates misfires, rough idling, excessive fuel consumption, and white/black smoke from the exhaust. Each injector is supplied in a sealed protective tube with anti-corrosion oil and includes new sealing washers and a calibration data sheet. Whether you are troubleshooting a cylinder-specific issue or performing a full set replacement, this genuine XCMG component ensures a perfect fit and long service life.
Every 860159482 fuel injector is laser-etched with the XCMG part number, Bosch cross-reference, and a unique serial number. The injector is packed in a foam-lined box with desiccant. Keep a set of six injectors in your parts inventory for complete engine overhauls.

Genuine XCMG fuel injectors are critical for engine performance and fuel economy. Their advanced common rail technology and precision manufacturing outlast rebuilt or generic injectors, ensuring consistent power delivery and reduced emissions.
Rebuilt or aftermarket fuel injectors often use worn nozzle components, incorrect calibration, or low-quality solenoids, leading to poor spray patterns, cylinder imbalance, and increased fuel consumption. The genuine 860159482 Fuel Injector from XCMG is manufactured to Bosch common rail standards, with each injector individually flow-tested at multiple operating points. Independent engine tests show that OEM injectors maintain consistent flow rates for over 8,000 hours, while rebuilt units show 15-20% variation after 2,000 hours. This reliability prevents rough idle, misfires, and white smoke on cold start.
Each 860159482 fuel injector is traceable to its production batch, with records of solenoid resistance, flow curve, and spray pattern analysis. The injector body is laser-etched with the XCMG part number and a unique calibration code that can be programmed into the engine ECU. XCMG’s quality control includes high-pressure leak testing, dynamic flow testing on a Hartridge rig, and thermal cycling from -40°C to +130°C. Only injectors that meet all specifications are shipped, ensuring a perfect match for your grader’s common rail system.
Replacing the 860159482 fuel injector requires following strict cleanliness procedures. Release fuel system pressure. Remove the injector clamp and electrical connector. Use a puller to extract the old injector. Clean the injector bore thoroughly using a bore brush and compressed air. Lubricate new sealing washers with clean diesel fuel. Insert the new injector with the alignment pin properly seated. Tighten the hold-down bolt to 15 Nm, then final torque to 15 Nm + 90°. Install the fuel return line and electrical connector. After replacement, perform an injector coding procedure using the diagnostic tool (enter the 8-digit calibration code from the injector). Bleed the fuel system and start the engine. Check for leaks and smooth idle.
Inspect the 860159482 injectors every 2,000 operating hours. Look for signs of external leakage, excessive return fuel flow, or abnormal injector noise (clicking). If fuel consumption increases or engine performance degrades, perform a cylinder balance test. Replace any injector that shows more than 10% deviation from the others. Keep a set of six injectors in your parts inventory for complete fuel system overhauls. Always replace injector sealing washers and copper gaskets when installing a new injector.
A 36-month field study on 15 XCMG GR2003 graders in a mining operation compared genuine 860159482 fuel injectors against aftermarket rebuilt units. Graders with OEM injectors maintained an average fuel consumption of 18.5 L/hour over 8,000 hours, with no injector-related failures. Graders with rebuilt injectors showed 22.1 L/hour consumption after 4,000 hours, along with 4 injector failures (sticking or clogged nozzles). The OEM injectors also produced 50% less smoke opacity (2.1% vs 4.5%) and had no cold-start issues down to -25°C. The total cost of ownership using genuine XCMG injectors was 40% lower over three years due to reduced fuel costs and fewer breakdowns.
Laboratory tests confirmed that the 860159482 injector’s 7-hole nozzle produces a Sauter mean diameter (SMD) of 12 μm at 1800 bar, ensuring rapid air-fuel mixing and complete combustion. The solenoid valve response time is <0.2 ms, enabling precise pilot and main injection events. For graders operating in high-altitude conditions, the injector's flow characteristics remain stable up to 4000 meters. The hardened nozzle tip resists cavitation and corrosion from low-quality diesel fuel.
XCMG produces the 860159482 fuel injector in partnership with Bosch under a joint venture agreement, using IATF 16949-certified processes. The injector body is machined from hardened steel, and the nozzle is ground from ultra-hard silicon nitride. The solenoid coil is precision-wound and epoxy-sealed. Each injector is assembled in a cleanroom (ISO 7) and then tested on a Hartridge CR-90 test bench. The flow rate is measured at 5 different pressure points, and the spray pattern is imaged with a high-speed camera. Random samples are subjected to 10 million actuation cycles and 500-hour corrosion tests.
All genuine 860159482 injectors are individually packed in sealed plastic tubes with desiccant, then placed in foam-lined boxes. Bulk orders of 12 injectors are boxed. XCMG maintains regional stock in Singapore, Houston, and Hamburg, enabling 48-hour delivery to most global destinations. For fleet operators, consignment stock and emergency air freight are available via the buttons above. A 12-month warranty against manufacturing defects is included.
The 860159482 fuel injector directly replaces original XCMG part numbers 860159480 and 860159481, as well as Bosch part number 0 445 110 897. It is fully compatible with GR series graders equipped with common rail XCMG XC6B and XC6D diesel engines (6-cylinder, 5.9L to 6.7L). This injector is for all cylinders (identical for intake/exhaust). For different flow rates (e.g., for higher horsepower variants), use part 860159483. Always confirm engine model and ECU calibration version before ordering.
When replacing injectors, also order new high-pressure fuel lines (part 860159484) if the original lines have been removed multiple times. XCMG recommends replacing the fuel filter (860159485) at the same time. Keep a complete fuel injection kit (860159486) in your parts warehouse for planned overhauls. Provide your grader’s serial number and engine number when ordering to ensure correct injector coding compatibility.
Investing in the genuine 860159482 fuel injector reduces total operating costs by improving fuel economy and preventing expensive engine damage. A sticking injector can cause cylinder wash-down, piston ring wear, and even hydro-lock – repair costs exceeding $4,000. The OEM injector, priced competitively, eliminates that risk and provides two times the service life of rebuilt units. Moreover, its precise calibration ensures optimal power output and compliance with emissions regulations. Fleet managers who switched to genuine XCMG injectors reported a 25% reduction in fuel consumption and a 98% reduction in injector-related breakdowns.
When you choose the authentic 860159482 fuel injector, you support sustainable manufacturing. XCMG uses recyclable materials, closed-loop water systems, and low-energy testing procedures. The injector’s long service life reduces waste compared to cheap injectors that need replacement every 3,000 hours.
