This precision component ensures leak-proof power delivery and consistent performance in GR series graders.
The 804400808 hose assembly features a two-layer high-tensile steel wire braid reinforcement and a premium synthetic rubber inner tube, offering excellent pressure resistance and durability. Its pre-crimped steel fittings ensure secure, leak-free connections.
Whether replacing a worn line or repairing a hydraulic circuit, this assembly guarantees consistent performance. With the 804400808, you ensure reliable hydraulic system operation.
The XCMG Hose Assembly 804400808 is a precision-engineered high-pressure hydraulic line designed for motor grader fluid power systems. It provides reliable, leak-proof fluid transmission between hydraulic pumps, control valves, and working actuators on XCMG GR series motor graders.
Each assembly is constructed with a two-layer high-tensile steel wire braid reinforcement and a premium NBR synthetic rubber inner tube, engineered to withstand extreme operating pressures up to 18 MPa (2,610 psi) in load-sensing hydraulic systems.
The hose assembly comes with pre-crimped steel end fittings attached using XCMG’s proprietary crimping process, which applies precise radial force to compress the ferrule onto the hose. This creates a permanent, leak-proof seal that meets or exceeds the burst pressure rating of the hose itself.
Furthermore, the 804400808 incorporates a premium abrasion-resistant synthetic rubber cover that provides excellent protection against ozone, UV exposure, and hydraulic oil permeation. This makes it ideal for open-pit mining, highway construction, and agricultural applications.
From a quality perspective, every assembly undergoes rigorous testing, including impulse testing per ISO 6803, to guarantee conformance to XCMG’s strict quality standards. The fittings are finished with zinc-nickel plating and trivalent chromate coating.
For maintenance teams, standardizing on the 804400808 simplifies inventory management, as this assembly is used across multiple XCMG grader models including GR135, GR165, GR180, GR215, GR260, GR300, and GR350.
In demanding construction environments, the 804400808 hose assembly has demonstrated exceptional durability. The two-layer steel wire braid provides excellent abrasion resistance and pressure containment, ensuring reliable performance even under extreme impulse spikes.
Unlike standard hoses, the genuine XCMG assembly features a specially formulated cover that resists weathering, ozone, and UV exposure, ensuring long-term reliability in harsh outdoor conditions. The corrosion protection exceeds 500 hours of salt spray resistance per ASTM B117.
The hose’s flexible design absorbs vibration and accommodates machine movements, reducing stress on connections and preventing premature failure. This is critical for graders operating in continuous articulation and blade rotation.
Moreover, the 804400808 is designed to operate effectively in a wide temperature range from -40°C to +120°C, maintaining its performance characteristics from cold starts to high-temperature working conditions.
When used with XCMG-recommended hydraulic fluids, this assembly achieves a long service life, reducing maintenance frequency and associated downtime. A leaking or burst hose can cause sudden loss of steering or blade control, leading to dangerous machine behavior and costly downtime.
With a proven track record in thousands of machines, the 804400808 hose assembly contributes significantly to the reliability, productivity, and safety of XCMG graders.
Installing the 804400808 hose assembly requires careful preparation. First, relieve system pressure and clean the connection areas to prevent contamination from entering the hydraulic system.
Remove the old assembly and inspect the fittings for any debris or damage. Ensure the new hose is routed correctly, avoiding sharp bends and abrasive contact that could compromise the hose integrity.
The factory pre-crimped fittings eliminate the need for field cutting or assembly, significantly reducing installation time and improving overall reliability. Simply connect the fittings and torque to the specified value using a calibrated wrench.
For maintenance, periodically inspect the hose for signs of abrasion, cracking, swelling, or leakage. Replace the assembly immediately if any damage is detected. A cracked, swollen, or abraded hose must be replaced promptly.
The 804400808 is designed for easy replacement. Always use a genuine XCMG assembly to ensure proper fit, correct bend radius, and long service life even under extreme temperature cycles and vibration.
Finally, document all maintenance activities and replacement intervals to support a proactive maintenance program and ensure the long-term reliability of your XCMG grader’s hydraulic system.
