Camshaft bushing for Komatsu GD511A

The camshaft bushing 6206-21-1420 serves as a support and sliding surface for the camshaft within the internal combustion engine. By providing a precise interface between the camshaft and the engine block, it facilitates smooth rotation and maintains the alignment necessary for proper valve timing. This component is engineered to operate within the lubrication system of the engine, ensuring that the camshaft rotates with minimal resistance during operation.

This part is specifically intended for the Komatsu S6D95L-1 engine, which powers equipment such as the Komatsu GD511A and GD511A-1 motor graders. It is a critical internal component that supports the valve train assembly to ensure the engine functions within its design parameters. Proper installation of this bushing is required to maintain the specified clearances between the camshaft and the engine block, which is necessary for the overall mechanical integrity of the engine assembly.

In internal combustion engines, camshaft bushings are used to support the camshaft at various points along its length. These bushings provide a bearing surface that accommodates the rotational forces exerted by the camshaft, while also helping to manage the oil film that is required for effective lubrication and heat dissipation during engine cycles.
