803404735 XCMG GR2605 motor grader hose assembly

803404735 XCMG GR2605 motor grader hose assembly

803404735 is the original high-pressure hydraulic hose assembly for the XCMG GR2605 grader. It’s used for flexible oil circuit connections in the hydraulic system, offering pressure resistance, pulse resistance, and shock absorption, ensuring precise, stable, and leak-free hydraulic operation of the entire machine.

Core Functions and Roles

Flexibly connects core components such as the hydraulic pump, valve group, and cylinders, stably delivering high-pressure hydraulic oil to drive the grader’s scraper, steering, and other working devices.

Absorbs vibration, shock, and thermal expansion and contraction during operation, preventing fatigue cracking of rigid pipes and oil leakage due to loose joints.

Original factory integrated crimping process ensures strong sealing performance, maintaining leak-free operation under high pressure and frequent pulse conditions.

Resistant to mineral oil, aging, and abrasion, suitable for harsh working environments such as construction sites with dust, mud, and high/low temperatures.

Replacement and Maintenance Points

Installation must follow the original factory piping layout. Twisting and forced stretching are strictly prohibited. Avoid prolonged friction with sharp corners and high-temperature components.

Thoroughly clean the oil circuit interfaces before installation. It is recommended to replace the sealing rings simultaneously. Tighten the connectors evenly according to the manufacturer’s recommended torque. Rough handling is strictly prohibited.

Regular inspections are necessary. During seasonal changes or major overhauls, focus on checking the aging of the hoses. Replace expired or damaged hoses promptly to reduce downtime risks.
