Camshaft bushing for Komatsu GD511A

The camshaft bushing, part number 6206-21-1430, serves as a sliding bearing that supports the camshaft within the internal combustion engine. By providing a low-friction surface for the camshaft to rotate, this component ensures the precise timing of the intake and exhaust valves. It is installed directly into the engine block to maintain the alignment of the camshaft during operation.

This component is designed for use in Komatsu machinery, specifically fitting the GD511A and GD511A-1 motor graders powered by the S6D95L-1 engine. Proper installation within the engine block is necessary to support the rotation of the camshaft, which governs the opening and closing cycles of the engine valves.

In internal combustion engines, camshaft bushings are utilized to reduce rotational friction between the camshaft journals and the engine block. These bushings are typically lubricated by the engine oil system to minimize wear and dissipate heat generated during high-speed rotation. Maintaining the correct clearance between the bushing and the camshaft journal is necessary to ensure consistent valve timing and overall engine efficiency.
