380903063 XCMG GR2605 motor grader connecting ring

380903063 XCMG GR2605 motor grader connecting ring

380903063 is a genuine XCMG GR2605 grader connecting ring, primarily used in steering linkages, tie rod joints, cylinder trunnions, and articulated joints. It handles precise connections between components, load transfer, and angle compensation, ensuring flexible and balanced mechanism movement.

Core Functions and Roles

Precise Connection: Serving as a transitional connector between linkages and pins, and between cylinders and the frame, it enables articulated assembly of multiple components, ensuring coaxiality and preventing stress concentration during assembly.

Load Transfer and Buffering: Transfers tensile, thrust, and impact loads during operation, working with bushings to absorb vibration and prevent loose bolts and fatigue fracture of parts.

Angle Adaptation: Allows articulated joints to swing flexibly within a designed angle, ensuring smooth and unhindered steering and blade tilting movements.

Key Technical Parameters

Model: 380903063
Name: Connecting Ring
Compatible Model: XCMG GR2605 Grader
Material: High-quality alloy steel forging, tempered heat treatment, blackened/galvanized for corrosion resistance, high shear strength, strong wear resistance
Features: Original factory precision machining, small hole diameter tolerance, flat mounting surface, good fit with pins and bushings, no gaps or looseness; rust-proof coating resistant to acids and alkalis, resistant to harsh outdoor working conditions.

Replacement and Maintenance Points

Replacement: Clean the mounting surface, replace with new bushings and pins simultaneously; tighten bolts diagonally and evenly to the specified torque, strictly prohibit forceful hammering during assembly; prioritize the use of original parts to avoid secondary damage caused by size mismatch.

Maintenance: Regularly check the tightness, apply grease to the hinges to reduce wear; clean surface dirt after operation to prevent rust; take rust prevention measures when storing for a long time.
