Genuine XCMG Hose Assembly with OEM number 803191860 is a high-performance hydraulic line engineered for motor grader fluid power systems. This critical component, 803191860, ensures reliable oil flow in steering, braking, and implement circuits. Manufactured with a synthetic rubber inner tube, two braided steel wire reinforcements, and an abrasion-resistant cover, it withstands extreme vibration, pressure spikes up to 350 bar, and harsh construction environments.
Engineered for XCMG GR215, GR300, GR350, and GR2405 motor graders, the 803191860 hose assembly features permanent crimped fittings with M18×1.5 metric threads and a 90° elbow for easy routing in tight engine compartments. Its 10mm inner diameter ensures optimal flow, while the weather-resistant outer cover resists UV, ozone, and abrasion.
By choosing OEM 803191860, maintenance teams eliminate hose burst risks, reduce downtime, and prevent costly fluid leaks. This genuine XCMG assembly guarantees perfect fitment, superior impulse endurance, and long-term reliability under continuous heavy-duty operation.

The XCMG 803191860 hose assembly features a seamless synthetic rubber tube that resists oil degradation and maintains flexibility at extreme temperatures. Two layers of braided steel wire provide exceptional impulse strength, tested to 1 million cycles at 133% working pressure per SAE 100R2AT.
The weather-resistant outer cover withstands UV exposure, ozone cracking, and abrasion from road debris. Permanent crimped fittings with zinc-nickel plating ensure zero leakage and resist corrosion in salt-spray environments, making it ideal for winter road maintenance.
Each assembly is proof-pressure tested at 700 bar before packaging, guaranteeing structural integrity and safety. XCMG uses computer-controlled crimping machines to ensure consistent compression and fitting retention.
The 803191860 hose assembly is typically installed between the steering control valve and the steering cylinder, as well as in the brake accumulator charge line. Its 90° elbow fitting allows compact routing around the engine and frame, avoiding sharp bends.
In the blade lift circuit, this hose connects the main control valve to the lift cylinder, withstanding frequent pressure reversals and shock loads. For the circle drive hydraulic motor, it ensures leak-free delivery of high-flow oil.
Using genuine 803191860 eliminates hose burst risks and downtime, especially in mining, quarrying, and heavy construction applications where reliability is critical.
Before installation, inspect the hose for any shipping damage. Ensure the fittings and port threads are clean. Apply a drop of clean hydraulic oil to the O-ring or washer. Tighten the fittings to 30–35 Nm using a torque wrench.
Avoid twisting the hose during installation. The minimum bend radius is 90 mm. Route the hose away from sharp edges, exhaust components, and moving parts. Use protective sleeving if necessary.
Inspect the hose assembly every 500 operating hours for signs of cover wear, cracking, or leakage. Replace immediately if the outer cover is cut or the steel wire is exposed. Never attempt to repair a damaged hose; replace the entire assembly.
Generic hose assemblies often use lower-grade rubber or insufficient wire reinforcement, leading to early failure. The OEM 803191860 meets SAE 100R2AT impulse endurance requirements, lasting over 1 million cycles.
Aftermarket crimping may cause fitting blow-off. XCMG uses computer-controlled crimping machines to ensure consistent compression. Burst tests confirm over 1400 bar, well above working pressure.
Investing in genuine XCMG 803191860 eliminates fluid leaks, reduces fire hazards, and extends component life, lowering total cost of ownership.
Each 803191860 hose assembly is manufactured in XCMG’s ISO 9001:2015 certified facility. Random samples undergo impulse testing, burst testing, and salt spray testing. Fittings are 100% inspected for thread quality and crimp diameter.
Full traceability from rubber batch to finished assembly allows quality audits. XCMG provides a 12-month warranty against manufacturing defects.
OEM 803191860 replaces older part numbers 803191858 and 803191859. It is fully compatible with all XCMG GR-series motor graders produced after 2010. For longer or shorter lengths, refer to 803191861 (2000mm) and 803191862 (1200mm).
Order this hose assembly together with replacement O-rings (803191863) and protective sleeving (803191864) for complete installation. Bulk packaging available for fleet maintenance.
Q: Can the 803191860 hose be used with phosphate ester fluids? A: No, the rubber tube is compatible with mineral oils and synthetics. For phosphate esters, use FKM hose (803191865).
Q: What is the recommended replacement interval? A: Replace every 2 years or 4000 operating hours, whichever comes first, or at the first sign of cover cracking.
Q: How to identify a genuine XCMG hose assembly? A: Genuine hoses have a printed XCMG logo and OEM number 803191860 on the cover.
Q: Can the fittings be reused? A: No, the crimped fittings are permanent. Do not attempt to re-crimp; replace the entire assembly.
