The 804423587 Hose Assembly is a genuine XCMG high‑performance hydraulic conduit engineered for reliable fluid power transmission on articulated dump trucks and heavy equipment. This OEM assembly, identified by part number 804423587, features a premium synthetic rubber inner tube, multiple layers of high‑tensile steel wire reinforcement, and a rugged, abrasion‑resistant outer cover that withstands extreme pressures, constant flexing, and harsh environmental conditions. Terminated with precision‑machined steel end fittings and factory‑crimped for a leak‑proof seal, the 804423587 hose assembly ensures dependable fluid transfer, exceptional impulse life, and long service life, making it an essential replacement component for maintaining hydraulic system performance and reducing downtime in mining, quarrying, and heavy construction operations.
The 804423587 Hose Assembly is a precision‑engineered hydraulic conduit designed to transmit pressurised fluid reliably in the demanding operating conditions of XCMG articulated dump trucks.
This genuine XCMG assembly is built to handle the high pressures, shock loads, and constant flexing inherent in steering, braking, and suspension circuits.
Its robust two‑wire braid reinforcement provides exceptional strength and flexibility, while the synthetic rubber inner tube resists oil degradation and maintains a smooth flow path.
The outer cover is engineered to withstand abrasion from road debris, rock impacts, and mud, ensuring long service life in rugged environments.
Factory‑crimped steel end fittings guarantee a leak‑free connection and eliminate the risk of hose blow‑off under pressure.
Each assembly is pressure‑tested before shipment, confirming its integrity and performance.
Hydraulic hoses are the lifelines of heavy equipment, transmitting power to actuate steering, brakes, and implements. A hose failure can cause sudden loss of control, creating serious safety hazards.
The 804423587 assembly is manufactured to stringent quality standards, delivering consistent performance and reducing the risk of unexpected rupture.
Its high impulse life rating ensures it can withstand the repeated pressure spikes that occur during normal machine operation, such as rapid steering inputs or braking cycles.
By using genuine XCMG hoses, operators maintain the original equipment’s safety margins and performance characteristics, protecting both personnel and machinery.
Regular inspection and timely replacement of hoses is a key preventive maintenance practice that extends the life of pumps, valves, and actuators.
The 804423587 hose assembly is engineered with a focus on pressure capacity, fatigue resistance, and ease of routing.
The two‑wire braid reinforcement is precisely balanced to provide maximum burst strength while allowing the hose to flex in tight installations.
The inner tube is compounded for low friction and high resistance to oil additives, ensuring consistent flow and minimal pressure drop.
The outer cover is designed to resist ozone cracking, UV degradation, and chemical attack from fuels and cleaning agents.
End fittings are machined from high‑grade steel and zinc‑plated for corrosion protection; the swaging process is computer‑controlled for consistent crimp diameter and integrity.
The hose is marked with the OEM number and production batch for traceability and quality assurance.
The 804423587 hose assembly is constructed from premium materials selected for their ability to perform in extreme mining and construction environments.
The NBR inner tube offers excellent resistance to petroleum‑based hydraulic fluids, even at elevated temperatures, preventing swelling and hardening.
The steel wire braid is made from high‑carbon steel with a protective zinc coating, ensuring long‑term corrosion resistance and fatigue strength.
The chloroprene (CR) outer cover provides superior abrasion and weather resistance, maintaining flexibility even in sub‑zero temperatures.
All materials are RoHS compliant, making the hose environmentally safe and suitable for use in regulated mining regions.
The 804423587 hose assembly is widely used on XCMG articulated dump trucks, wheel loaders, excavators, and motor graders for fluid power transmission in steering, braking, suspension, and implement circuits.
It is commonly installed between the steering orbital valve and the steering cylinders, or between the brake valve and the brake actuators.
In underground mining, the hose’s robust cover resists damage from rock falls and abrasive dust, ensuring reliable operation in confined spaces.
Its standard M22 x 1.5 fittings allow for quick, simple replacement using common tools, reducing maintenance time.
The hose’s bend radius and flexibility make it suitable for tight engine bay and chassis routing.
Every 804423587 hose assembly is manufactured in an ISO 9001 certified facility under strict quality control procedures.
Incoming rubber compounds and steel wire are tested for tensile strength, hardness, and adhesion to specification.
During production, the hose is continuously monitored for dimensional accuracy, concentricity, and cover thickness.
After crimping, each assembly is proof‑tested to 100% of working pressure and checked for leakage.
A random sample from each batch undergoes impulse testing per SAE J343, with a minimum of 400,000 cycles at 133% working pressure.
Only hoses that pass all tests are released, guaranteeing performance and reliability.
The 804423587 hose assembly is a direct replacement for the original hose on XCMG articulated dump trucks, including XDA30, XDA40, XDA45, XDA45U, XDA60, TA30, AD45, AD60, and many other models.
It is also compatible with various wheel loaders, excavators, and motor graders that use the same hose and fitting configuration.
The M22 x 1.5 thread and 24° cone sealing are standard across many hydraulic systems, simplifying cross‑brand replacement.
For non‑XCMG applications, verify that the working pressure, hose diameter, and end fittings match your requirements.
Always consult your machine’s parts manual to confirm the correct part number before ordering.
Replacing the 804423587 hose assembly requires basic hydraulic tools and cleanliness. Always depressurise the circuit before starting work.
Remove the old hose and carefully note the routing and fitting orientation to avoid twisting the new assembly.
Install the new hose, ensuring no sharp bends or kinks. Tighten the fittings to the recommended torque (35‑40 N·m).
Purge the circuit to remove trapped air, then run the system at low pressure and check for leaks.
During routine inspections, check the hose for abrasion, cracking, or bulging. Replace immediately if any damage is evident.
Maintain a spare hose in stock to minimise downtime during unexpected failures.
The 804423587 hose assembly complies with SAE J517 (100R2) and DIN EN 853 standards for high‑pressure hydraulic hoses.
It meets the impulse test requirements of SAE J343, ensuring long‑term durability under cyclic pressure loading.
All materials are RoHS compliant and free from restricted substances.
Using genuine XCMG hoses ensures compliance with original equipment safety and performance specifications.
Always replace hoses that have exceeded their service life or show any signs of deterioration.
Aftermarket hoses often use inferior rubber compounds, lower‑grade wire, or imprecise crimping, resulting in premature failure and safety risks.
