803175554 XCMG GR2605 motor grader hose assembly

803175554 XCMG GR2605 motor grader hose assembly

803175554 is the original hydraulic hose assembly for the XCMG GR2605 grader. It consists of a high-pressure hose and precision crimp connectors, used for flexible connections in the hydraulic system. It adapts to the vibration conditions of the entire machine, is pressure-resistant, leak-proof, and anti-aging, ensuring stable hydraulic oil delivery.

Core Functions and Roles

Flexible Connection and Compensation: Absorbs vibration, impact, and thermal expansion and contraction displacement of the pipeline during grader operation, preventing fatigue cracking of rigid pipes and protecting oil circuit interfaces.

High-Pressure Oil Delivery: Adapts to high-pressure conditions in the hydraulic system, efficiently delivering hydraulic oil between pumps, valves, cylinders, and motors, with no leakage and minimal pressure drop.

Harsh Working Conditions Resistance: Resistant to oil contamination, UV radiation, and high and low temperatures, adaptable to complex environments such as construction sites with dust, mud, and large temperature differences.

Convenient Installation and Maintenance: Standardized assembly design allows for quick disassembly and replacement, reducing downtime.

Replacement and Maintenance Points

Replace after depressurizing the machine; never operate under pressure. Clean the connectors and oil line interfaces before installation, and fix according to the original factory routing to avoid hose twisting, bending, and friction.

Use only original factory assemblies; avoid using non-standard hoses. Replace the corresponding seals simultaneously and tighten the connectors to the specified torque.

Regularly inspect the hose surface and connectors; shorten the inspection cycle under harsh working conditions. Never use the hose to drag heavy objects or as a support point.
