380904143 XCMG GR2605 motor grader spacer

380904143 is a dedicated spacer for the XCMG GR2605 grader, used in hinges, connecting rods, pins, and suspension components. It serves to position gaps, isolate spacing, provide load support, and protect the bushings.

Core Functions and Roles

Controls the assembly clearance between pins, connecting rods, and bushings, ensuring precise component positioning and preventing movement or misalignment.

Separates two parts, preventing friction and collision during operation, reducing wear.

Bears axial loads, distributes pressure, and protects shaft ends, end covers, and bushings from crushing damage.

Ensures reasonable mechanism clearances, resulting in smooth and noiseless steering, lifting, and tilting movements.

Key Technical Parameters

Model: 380904143
Name: Spacer
Compatible Model: XCMG GR2605 Grader
Material: High-quality alloy steel, wear-resistant, pressure-resistant, and not easily deformed
Features: High original factory dimensional accuracy, good concentricity of inner and outer diameters, smooth surface, wear-resistant and pressure-resistant

Replacement and Maintenance Points

During installation, ensure the spacer is concentric with the pin and bushing, without skewing or jamming.

Clean the mating surfaces during assembly to prevent impurities from entering and causing abnormal wear.

If the clearance is too large or the parts wobble, replace with a standard spacer promptly.
