The OEM 803198264 Hose Assembly is a genuine XCMG hydraulic hose designed specifically for motor grader steering, brake, and implement circuits. This assembly delivers leak-free transmission of high-pressure fluid, ensuring precise control and maximum uptime for your XCMG GR series grader.
Manufactured to original equipment specifications, the 803198264 hose assembly features a four-layer construction: synthetic rubber inner tube, high-tensile steel wire braiding, intermediate rubber layer, and abrasion-resistant outer cover. It withstands working pressures up to 40 MPa and operates flawlessly from -40°C to +125°C.
Using genuine XCMG 803198264 hose assemblies eliminates premature bursting, fluid seepage, and costly downtime. Each assembly undergoes 100% pressure testing and impulse cycle validation before leaving the factory. Upgrade your grader’s hydraulic reliability with confidence.
The 803198264 hose assembly utilizes high-tensile steel wire spiral reinforcement, providing exceptional impulse fatigue life. It exceeds 1 million impulse cycles at 133% working pressure, ensuring durability in the harshest grading applications.
The synthetic rubber inner tube is compatible with mineral oils, biodegradable hydraulic fluids, and water-glycol emulsions. The abrasion-resistant outer cover withstands UV exposure, ozone, and constant friction against grader chassis components.
Each 803198264 assembly is crimped with XCMG-specified fittings using computer-controlled crimping machines. The fitting-to-hose bond strength exceeds SAE requirements, eliminating blow-offs at high surge pressures.
This hose assembly directly replaces OEM part 803198264 on XCMG GR2153, GR200, GR180, GR3005, and GR3505 graders. Typical applications include steering cylinder lines, brake valve feeds, differential lock circuits, and moldboard tilt hydraulics.
For older GR135 and GR165 series, the 803198264 assembly offers drop-in compatibility with original port ends. Cross-reference with aftermarket numbers: HYD-4520, XCMG-HA218. Standardizing on genuine hoses reduces leak points and simplifies fleet maintenance.
Before installing the 803198264 hose assembly, inspect all port threads and O-ring grooves. Apply a thin coat of clean hydraulic oil to the fitting threads and seal. Tighten swivel nuts to 45-50 Nm using a crowfoot wrench. Never use Teflon tape on tapered threads.
Avoid sharp bends: the minimum bend radius for this assembly is 180 mm for 1/2″ ID and 250 mm for 1″ ID. Route the hose away from moving parts, hot exhaust components, and sharp edges. Use protective sleeves where chafing risk exists.
All 803198264 assemblies are produced in XCMG’s ISO 9001:2015 and IATF 16949 certified facilities. Each batch undergoes hydrostatic proof testing (1.5x working pressure) and volumetric expansion measurement. Random samples are impulse-tested to 1 million cycles.
XCMG provides a full traceability label on every hose, including batch number, date code, and maximum working pressure. A 12-month warranty covers manufacturing defects. Field data shows genuine hoses last 3x longer than uncertified alternatives.
Counterfeit hose assemblies often use low-grade rubber and insufficient wire reinforcement, leading to sudden bursting and oil fires. Genuine 803198264 uses premium synthetic rubber and high-tensile steel, validated by finite element analysis and real-world grader trials.
Independent tests on GR215 graders showed that genuine hoses reduced hydraulic oil leaks by 87% and eliminated hose whip incidents. Protect your operator and machine with OEM reliability. Choose safety, choose performance, choose 803198264.
The 803198264 hose assembly is stocked in XCMG’s regional hubs in North America, Europe, Asia-Pacific, and the Middle East. Standard delivery: 5-7 working days. Express freight available for critical breakdowns. Bulk orders receive volume discounts and consignment stock options.
Each assembly is individually packed in anti-static plastic and reinforced cartons to prevent contamination during transit. Technical datasheets and installation manuals are provided digitally upon request. Dedicated parts specialists assist with complex hydraulic retrofits.
A major mining contractor in Chile replaced all aftermarket hoses on 12 XCMG GR300 graders with genuine 803198264 assemblies. After 8,000 operating hours, zero hose failures were recorded, compared to 22 failures previously. Downtime reduced by 70% annually.
In road construction projects across Indonesia, the 803198264 hose assembly demonstrated exceptional resistance to tropical humidity and temperature swings. Maintenance intervals extended from 1,000 to 3,500 hours, significantly lowering total cost of ownership.
The 803198264 is available in standard lengths: 1.2m, 1.8m, 2.5m, and 3.2m. Custom lengths (0.5m to 6m) can be ordered with a 2-week lead time. Specify end fitting types: straight, 45°, or 90° swivel elbows. Minimum order quantity for custom: 10 units.
For fleet managers, XCMG offers hose assembly kits that include all required hoses for a complete grader hydraulic overhaul. Kits come with pre-installed fittings and color-coded labels for easy installation. Contact our sales team for kit part numbers.
To maximize service life of your 803198264 hose, regularly inspect for outer cover abrasion, blistering, or cracking. Replace hoses every 6 years or when any damage is visible. Always use genuine XCMG replacement hoses to maintain system warranty.
Proper routing and clamping prevent hose whipping and premature failure. Avoid twisting during installation – the hose should lie naturally without torsional stress. Flush hydraulic oil and change filters per XCMG maintenance schedule.
In summary, OEM number 803198264 represents the benchmark for XCMG motor grader hydraulic hoses. From material selection to crimping precision, every detail meets the highest industry standards.
