OEM 804019972 The XCMG Oil Cooler (804019972) is a genuine OEM high‑efficiency heat exchanger engineered to maintain optimal fluid temperatures in the hydraulic systems, transmissions, and torque converters of XCMG articulated dump trucks. This critical cooling component, identified by part number 804019972, ensures that hydraulic oil and transmission fluid remain within their ideal operating temperature range, preventing degradation, viscosity loss, and component damage in the most demanding mining and construction applications.
Manufactured from high‑grade aluminum alloy with advanced fin-and-tube core technology, the 804019972 oil cooler delivers exceptional heat dissipation while maintaining low pressure drop and high flow capacity. Its robust construction, including heavy‑duty brazed joints and corrosion‑resistant coatings, withstands the extreme vibration, thermal cycling, and contamination typical of off‑road mining operations.
The 804019972 oil cooler is fully compatible with XCMG ADT series, providing a direct replacement solution that restores original cooling performance, protects expensive hydraulic and transmission components, and maximises uptime – keeping your fleet productive and reliable.
The 804019972 Oil Cooler is purpose‑designed to manage the thermal loads generated by hydraulic pumps, torque converters, and transmissions on XCMG articulated dump trucks, preventing overheating that can cause premature fluid breakdown and component wear.
Articulated dump trucks operate continuously in high‑ambient temperatures and under heavy loads, generating significant heat that must be dissipated to maintain fluid viscosity and protect pumps, motors, and valves.
This genuine XCMG oil cooler uses a high‑efficiency aluminum core with offset strip fins and turbulators that maximise surface area and promote turbulent airflow, achieving superior heat transfer per unit volume.
The brazed construction ensures leak‑free joints that withstand thermal cycling and pressure fluctuations without failure, while the corrosion‑resistant coating protects against environmental attack from salt, dust, and chemicals.
Its low internal pressure drop ensures that fluid flows freely, minimising parasitic losses and maintaining efficient system operation even under high flow conditions.
Field data from mining operations shows that genuine XCMG oil coolers reduce average hydraulic oil temperatures by 10‑15°C compared to blocked or aftermarket units, extending oil life and pump reliability.
The 804019972 Oil Cooler is essential for maintaining the chemical and physical properties of hydraulic and transmission fluids, directly influencing the lifespan of pumps, motors, and gearboxes.
Excessive fluid temperatures accelerate oxidation, reduce viscosity, and cause formation of sludge and varnish that clog valves and restrict flow, leading to erratic operation and component failure.
This genuine XCMG cooler restores factory‑spec heat rejection, ensuring that oil temperatures remain within the ideal 70‑90°C range, where fluid life is maximised and wear is minimised.
Proper cooling also reduces thermal stress on seals and hoses, preventing premature hardening, cracking, and leakage that can result in fluid loss and environmental contamination.
Fleet operators have reported a 35% extension in hydraulic oil change intervals after installing genuine XCMG coolers, significantly reducing fluid consumption and disposal costs.
Regular inspection of cooler fins, core cleanliness, and flow is recommended; blocked or damaged cores should be replaced immediately to restore cooling performance.
The 804019972 Oil Cooler is manufactured using controlled atmosphere brazing (CAB) technology, producing strong, consistent joints without flux residue, ensuring uniform heat transfer and long‑term reliability.
The aluminum alloy used for the core and tubes offers excellent thermal conductivity, lightweight properties, and corrosion resistance, ideal for mobile equipment applications.
XCMG’s engineering team has optimised fin density and louver patterns to balance airflow resistance and heat transfer, achieving maximum cooling in compact packaging.
The heavy‑duty inlet and outlet connections are precision‑machined and reinforced to withstand high pressure and vibration, preventing leaks at critical points.
All coolers are pressure‑tested to 1.5 times maximum operating pressure to verify integrity before release, guaranteeing leak‑free operation under service conditions.
The production facility is ISO 9001 and ISO 14001 certified, ensuring consistent quality and environmental responsibility.
The 804019972 Oil Cooler features a multi‑pass, cross‑flow core design that ensures even temperature distribution across the entire heat exchange surface, eliminating hot spots that degrade fluid.
The offset strip fins create turbulence in the air stream, breaking the boundary layer and significantly enhancing convective heat transfer compared to plain fins.
The internal oil turbulators induce swirling flow, increasing heat transfer on the liquid side and reducing the thermal resistance that limits cooler performance.
All joints are brazed at high temperature in a vacuum or controlled atmosphere, creating metallurgical bonds that are as strong as the base material and resistant to fatigue.
Thermal performance testing (per ISO 9168) has confirmed that the cooler achieves ≥90% of theoretical heat rejection across the operating flow range, ensuring consistent cooling.
The materials and processes are RoHS compliant and meet stringent environmental regulations.
The 804019972 Oil Cooler is designed for straightforward replacement by trained technicians using standard workshop tools, minimising machine downtime.
Begin by safely isolating the hydraulic or transmission system, relieving pressure, and draining the fluid to prevent spillage during removal.
Disconnect the oil lines and mounting bolts, carefully remove the old cooler, and inspect the surrounding area for debris or damage.
Clean the mounting surface and line fittings, then position the new 804019972 cooler, ensuring correct alignment with the fan or airflow path.
Reconnect the oil lines using new O‑rings or seals, torque fasteners to specification, and refill the system with the recommended fluid, checking for leaks on startup.
A typical cooler replacement can be completed in 2‑3 hours, restoring full cooling capacity and protecting vital driveline components.
Investing in the 804019972 Oil Cooler delivers significant long‑term savings by extending fluid life, reducing component wear, and preventing costly overheating‑related failures.
A single hydraulic pump failure due to overheating can cost over $8,000 in parts and labour – this cooler prevents that risk by maintaining safe operating temperatures.
Extended fluid drain intervals (up to 35% longer) reduce fluid purchase and disposal costs, which can amount to thousands of dollars annually per machine.
Improved cooling also reduces fan clutch activation, saving fuel and reducing parasitic losses in the cooling system.
Field data from a large gold mine showed a 40% reduction in hydraulic pump replacements after installing genuine XCMG oil coolers across their fleet.
The cooler’s robust construction ensures it lasts the full service life, offering excellent return on investment.
