803184696 XCMG GR2605 motor grader hose assembly

803184696 XCMG GR2605 motor grader hose assembly

The 803184696 hose assembly is a core component of the XCMG GR2605 grader’s original hydraulic piping system. It is compatible with the machine’s high-pressure hydraulic system, undertaking the crucial tasks of stable hydraulic oil delivery and pressure transmission. It directly impacts the accuracy and response speed of key actuators such as the shovel angle control circuit, the left articulated steering assist circuit, and the hydraulic valve group input branch lines. In harsh operating environments involving long-term heavy loads, high-frequency vibrations, and dust and mud erosion, such as highway construction, mine stripping, airport runway construction, and large-scale earthwork projects, it can reliably withstand high-pressure impacts and is less prone to bursting, oil leakage, aging cracking, and other malfunctions. This effectively reduces the frequency of hydraulic system downtime for maintenance, ensuring continuous equipment operation efficiency. The hose features a three-layer reinforced composite structure upgrade design. The inner tube is made of imported oil-resistant nitrile rubber (NBR), with an oil swelling rate of ≤2.1% and excellent chemical corrosion resistance. It is compatible with XCMG original L-HM 46/68 anti-wear hydraulic oil and high-temperature hydraulic oil. The middle layer is a high-tensile-strength galvanized steel wire braided reinforcement layer, using a high-density braiding process, with a breaking strength ≥2050MPa, providing more stable pressure resistance and better deformation resistance. The outer rubber layer is made of wear-resistant and weather-resistant special synthetic rubber material with a Shore hardness of 69HA, excellent flexibility, UV aging resistance, and outstanding resistance to sand and gravel abrasion. It showed no cracking or fading after 6300 hours of outdoor aging testing. The connector is precision forged from 40# steel and treated with phosphate and galvanizing for double anti-corrosion. It is equipped with original factory-customized fluororubber (FKM) sealing rings, achieving an IP66 protection level for sealing performance. It perfectly matches the original vehicle interface specifications and can directly replace aged or damaged original vehicle hoses.
