803370406 XCMG GR2605 motor grader connector

803370406 is an original equipment manufacturer (OEM) hydraulic connector for the XCMG GR2605 grader. It is primarily used for connecting hydraulic lines, valve blocks, oil pumps, and cylinders. It features pressure resistance, sealing, shock resistance, and anti-loosening properties, ensuring stable operation of the hydraulic system.

Core Functions and Roles

It enables the connection and transfer of hydraulic lines between each other and between lines and valves/cylinders, ensuring smooth hydraulic oil flow.

Its precision sealing structure prevents oil leakage under high pressure and vibration conditions, ensuring stable system pressure.

It uses OEM standard threads and interfaces, ensuring high compatibility and secure installation, preventing loosening or stripping even after long-term operation.

It is made of high-strength material, resistant to oil, corrosion, and impact, making it suitable for harsh construction site conditions.

Key Technical Parameters

Model: 803370406
Name: Connector
Compatible Model: XCMG GR2605 Grader
Material: High-strength carbon steel, surface rust-proof and corrosion-resistant treatment
Features: Original factory specifications, reliable sealing, pressure-resistant, vibration-resistant, high thread precision, and a perfect fit

Replacement and Maintenance Points

Clean the interface and sealing surface before installation. Tighten to the standard torque, avoiding excessive force that could damage the threads.

It is recommended to replace the sealing ring and gasket simultaneously to completely eliminate the risk of leakage.

Daily inspections should check the tightness of the fasteners. Address any oil leaks or loosening promptly.

After installation, test the machine under no-load to check for leaks and whether the solenoid valve operates normally; routinely inspect the tightness and periodically clean surface oil and dust.
