Bushing for Komatsu GD511A

The 6204-51-1711 bushing acts as a sliding bearing within the mechanical assemblies of the grader. By providing a controlled contact surface between moving parts, it supports radial and axial loads while protecting primary structural components such as pins, shafts, and pivots from direct contact and wear. This component is essential for maintaining the alignment and smooth operation of articulated joints and hydraulic cylinder mounting points.

This part is compatible with the Komatsu GD511A, GD511A-1, and GD511A-1 motor grader equipped with the S6D95L-1 engine. It is engineered to fit specific housings within the grader's steering, frame articulation, and blade control systems, ensuring precise movement and minimal clearance during operation. Proper installation of this bushing helps maintain the structural integrity of the machine joints under constant load and vibration.

In heavy machinery, bushings function by separating moving surfaces to prevent metal-to-metal contact. They are typically installed in locations where rotational or oscillating motion occurs, allowing for efficient movement while absorbing the forces transmitted through the equipment's linkages. Regular inspection and replacement of these components are standard maintenance practices to prevent excessive play in the machine's articulated systems.
