The genuine XCMG Fan with OEM number 800171842 is a high-performance engine cooling fan designed for XCMG articulated dump trucks and heavy off-highway equipment. This fan moves large volumes of air through the radiator, charge air cooler, and hydraulic oil cooler, maintaining optimal operating temperatures under extreme loads. Engineered from advanced composite materials, the OEM 800171842 fan ensures reliable cooling in mining and construction environments.
The XCMG Cooling Fan 800171842 is purpose-built for articulated dump trucks operating in high-ambient temperatures, steep grades, and dusty conditions. It draws air through the radiator core at up to 12,500 m³/h, preventing coolant overheating and ensuring engine power remains consistent. The 9-blade asymmetrical design reduces fan noise by up to 4 dB(A) compared to symmetrical fans, improving operator comfort during long shifts.
This fan directly replaces OEM units on AD45 through AD100 models. It is calibrated to work with viscous fan clutches or direct drive hubs. Field tests show that using the genuine 800171842 fan reduces coolant temperature spikes by 15°C under full-load climbing, extending engine head gasket and radiator life significantly.
Blades are molded from PA66 with 35% glass fiber reinforcement, providing excellent fatigue resistance and stiffness across a -40°C to +120°C range. The material resists stone impact and chemical attack from coolant or oil mist. Each blade profile is optimized using CFD (computational fluid dynamics) to maximize pressure rise while minimizing horsepower draw from the engine.
The aluminum die-cast hub features a corrosion-resistant coating (MIL-A-8625 Type III anodizing). Ultrasonic welding combined with stainless steel rivets attaches blades to the hub – a redundant joint that prevents blade separation even at 2,500 RPM. Dynamic balancing to ISO G6.3 ensures vibration-free operation, protecting water pump bearings and fan drive belts.
The 800171842 fan is a direct OE replacement for all AD-series trucks manufactured after 2015. Its 710 mm diameter, 8-bolt mounting pattern, and 65 mm pilot bore match the fan clutch interface exactly. No modification to the fan shroud or radiator guard is required. For older AD45 trucks with 680 mm fans, this fan can be retrofitted if the shroud is also upgraded – contact XCMG parts for compatibility.
Beyond dump trucks, the same fan is used on XE470LC excavators and LW900K wheel loaders that share the Cummins QSX15 engine platform. When ordering, verify the rotation direction: clockwise (suction) is standard. Counterfeit fans often have reverse rotation, causing overheating due to air being pushed forward instead of being drawn through the radiator.
To install the Fan 800171842, safely lock the engine from rotating. Remove the existing fan bolts (M10) using a 17 mm socket. Inspect the viscous clutch or fan hub for oil leaks or bearing play – replace if defective. Clean the mounting face and apply threadlocker (Loctite 243) to the new bolts. Torque bolts in a star pattern to 45 Nm.
After installation, spin the fan manually to ensure no contact with the shroud. Start the engine and run at idle; the fan should engage as coolant temperature rises. Use an infrared tachometer to verify fan speed matches clutch command. If fan vibrates excessively, rebalance by checking for cracked blades or missing weights – but genuine XCMG fans are pre-balanced and should not require field adjustment.
Common indicators of a failing fan include cracked blade roots, uneven blade pitch, or vibration that worsens with RPM. A blade that detaches at high speed can puncture the radiator, destroy the fan shroud, and damage the hood. In AD-series trucks, a single fan blade failure often leads to $5,000–$10,000 in collateral damage, plus extended downtime.
Counterfeit fans often use recycled nylon with insufficient glass fiber content; they become brittle in cold weather and crack after 500 hours. Genuine XCMG 800171842 fans have a service life exceeding 8,000 hours in normal duty (or 5,000 hours in severe dust/sand). Replace the fan whenever you replace the viscous clutch – the cost of the fan is minimal compared to engine overheating repairs.
Every XCMG Fan 800171842 is manufactured in an IATF 16949 facility. Each fan is 100% dynamically balanced and tested for burst speed at 3,200 RPM (28% safety margin). X-ray inspection verifies weld integrity at blade-hub junctions. The fan is marked with the XCMG logo, OEM number, and date code on the hub face. Packaging includes a holographic seal and QR code for authenticity verification.
Counterfeit fans often omit the stainless steel rivets and rely solely on plastic welding, which fails under thermal cycling. Some fakes use a different bolt hole pattern (e.g., 6-hole instead of 8-hole) leading to improper clamping. Protect your engine and cooling system – always insist on genuine XCMG parts. The OEM 800171842 fan delivers reliable cooling for years, even in the most demanding aggregate and mining operations.
The 9-blade design uses staggered leading edges and variable blade spacing to disperse tonal peaks. This results in a 4 dB(A) reduction in overall fan noise without sacrificing airflow. For AD-series operators, that means lower cab noise and less driver fatigue. Additionally, the optimized blade sweep angle reduces fan power consumption by 8% compared to older 7-blade designs, saving fuel.
If noise persists after installation, check for missing fan shroud seals or debris lodged between blades. The fan should not contact the shroud at any RPM – a gap of at least 10 mm is required. Genuine XCMG fans are matched to the AD-series shroud geometry, so interference indicates a misaligned engine mount or damaged shroud, not a fan defect.
XCMG is committed to eco-friendly manufacturing: the fan’s nylon material is produced using 30% recycled industrial waste, and the aluminum hub is made from post-consumer recycled alloy. The fan’s long service life reduces waste generation. Furthermore, its high efficiency lowers engine fuel consumption and CO₂ emissions by up to 1.5% per machine annually – a significant saving for large fleets.
When the fan eventually reaches end-of-life, the aluminum hub can be recycled, and the nylon blades can be shredded and reprocessed into non-critical parts. Choose genuine XCMG 800171842 for performance, safety, and environmental responsibility. Keep your articulated dump trucks cool and productive with XCMG original cooling components.
