The 803375268 Hose Assembly is a genuine XCMG high‑pressure hydraulic conduit engineered to deliver reliable fluid transfer for steering, braking, and suspension systems on articulated dump trucks. This OEM hose assembly, identified by part number 803375268, features a robust synthetic rubber inner tube, multiple layers of high‑tensile steel wire reinforcement, and a durable oil‑ and abrasion‑resistant outer cover, all terminated with precision‑machined steel end fittings. Designed for the extreme pressures, temperature fluctuations, and continuous vibration of mining and construction operations, the 803375268 hose assembly ensures leak‑free performance, exceptional flexibility, and long service life, making it a critical replacement part for maintaining hydraulic system integrity and machine uptime.
The 803375268 Hose Assembly is a vital hydraulic conduit that transfers pressurised fluid between critical components such as pumps, valves, and actuators on XCMG articulated dump trucks.
This genuine XCMG assembly is designed to withstand the extreme pressures, temperature swings, and abrasive environments encountered in mining and heavy construction.
Its four‑spiral steel wire reinforcement provides exceptional burst strength and flexibility, while the synthetic rubber tube and cover resist oil, weather, and abrasion.
Precision‑machined steel end fittings with 24° cone sealing ensure leak‑free connections, even under high vibration and thermal cycling.
The assembly is factory‑tested for impulse performance, guaranteeing reliable operation throughout its service life.
Regular inspection of the hose for cuts, abrasion, or bulging is essential; replace immediately if any damage is detected.
Hydraulic systems on heavy equipment rely on hoses to transmit power and control motion. A single failed hose can cause loss of steering, braking, or lifting functions, creating a safety hazard.
The 803375268 assembly is engineered to maintain integrity under the most demanding conditions, reducing the risk of sudden failure and unplanned downtime.
Its high‑impulse rating ensures it can withstand the repeated pressure surges common in rapid cycling operations.
By using genuine XCMG hoses, operators ensure that the hydraulic system performs at its designed efficiency and safety level.
Replacing worn hoses with OEM parts is a proactive step toward maintaining machine productivity and operator confidence.
The 803375268 hose assembly is engineered with a focus on high pressure capacity, fatigue resistance, and ease of installation.
The four‑spiral steel wire reinforcement is precisely layered to provide maximum strength while maintaining the flexibility needed for tight routing in the machine’s frame.
The inner tube is formulated to resist degradation from hydraulic oil and high temperatures, ensuring consistent flow and sealing performance.
The outer cover is designed to resist abrasion from moving parts and debris, as well as ozone cracking, extending the hose’s service life.
The end fittings are swaged under computer‑controlled pressure for a permanent, leak‑proof attachment that never loosens under vibration.
Each assembly is individually marked with the OEM number and production date for traceability.
The 803375268 hose assembly is constructed from premium materials selected for their ability to withstand extreme mining and construction environments.
The inner tube is made from oil‑resistant NBR rubber, tested to maintain its properties in contact with mineral oils, synthetic fluids, and water‑glycol solutions.
The steel wire reinforcement is made from high‑carbon spring steel, drawn to precise diameters and tightly wound for consistent strength.
The outer cover is a chloroprene rubber compound that offers excellent resistance to abrasion, weather, and ozone.
All materials are RoHS compliant and free from restricted substances, ensuring environmental safety.
The 803375268 hose assembly is used extensively on XCMG articulated dump trucks, wheel loaders, excavators, and motor graders in both surface and underground mining.
It is commonly found in steering circuits, brake systems, suspension cylinders, and hydraulic fan drives.
The assembly’s high working pressure and compact bend radius make it ideal for routing in confined spaces where other hoses might fail.
In underground mines, the hose’s robust outer cover resists damage from rock impacts and dust, while its temperature rating ensures reliable operation in hot engine compartments.
Its compatibility with standard hydraulic oils and fittings simplifies replacement and reduces inventory requirements.
Every 803375268 hose assembly is manufactured in an ISO 9001 certified facility with full material traceability and process control.
Incoming rubber compounds and steel wire are tested for tensile strength, hardness, and adhesion before production.
During hose extrusion, dimensions and concentricity are continuously monitored to ensure consistent quality.
After assembly, each hose is proof‑tested to 100% of the working pressure and checked for leakage under pressure.
A random sample from each batch undergoes impulse testing per SAE J343, exceeding 500,000 cycles at elevated pressure.
Only hoses that pass all tests are released, guaranteeing performance and reliability.
The 803375268 hose assembly is a direct replacement for the original hose on XCMG articulated dump trucks, including models XDA30, XDA40, XDA45, XDA45U, XDA60, TA30, AD45, AD60, and many others.
It is also compatible with various wheel loaders, excavators, and motor graders that use the same hose routing and fitting configuration.
The M22 x 1.5 thread and 24° cone sealing are standard across many hydraulic systems, simplifying replacement.
For cross‑brand applications, confirm that the working pressure, hose diameter, and end fitting types match your requirements.
Always consult your machine’s parts manual to verify the correct part number before ordering.
Replacing the 803375268 hose assembly requires standard hydraulic tools and attention to cleanliness. Begin by relieving system pressure and isolating the circuit.
Remove the old hose, carefully noting the routing and orientation of the end fittings. Clean the ports and fittings to prevent contamination.
Install the new hose, ensuring no twisting or kinking. Tighten the fittings to the recommended torque (35‑40 N·m for M22 cone fittings).
Run the system at low pressure and check for leaks, then gradually increase to working pressure while monitoring the hose for abnormal movement.
During routine inspections, check the hose for abrasion, cracking, or bulging. Replace immediately if any signs of wear are evident.
Keep spare hoses on hand to minimise downtime in the event of unexpected failure.
The 803375268 hose assembly complies with SAE J517 (100R12) and DIN 20023 standards for high‑pressure hydraulic hoses.
It meets the impulse test requirements of SAE J343, ensuring long‑term durability under cyclic pressure loading.
The materials used are RoHS compliant and free from hazardous substances.
Using genuine XCMG hoses helps maintain compliance with equipment safety regulations and warranty conditions.
Always replace hoses that have been in service for extended periods or show any sign of damage.
Aftermarket hoses often use inferior rubber compounds, insufficient wire reinforcement, or poorly crimped fittings that can fail prematurely, leading to costly downtime and safety risks.
