The piston assembly 6207-31-2120 consists of the piston body and the clips required for installation. This component operates within the combustion chamber of the engine, where it facilitates the conversion of combustion energy into mechanical movement. The clips included in this set secure the piston pin, ensuring the correct articulation between the piston and the connecting rod during engine operation.
This assembly is compatible with Komatsu GD511A, GD511A-1, and GD511A-1 motor grader models equipped with the S6D95L-1 engine. The component is manufactured to meet the specific dimensional and tolerance requirements for these engine configurations.
In an internal combustion engine, the piston serves as the primary moving component that transfers force from expanding gases in the cylinder to the crankshaft via the connecting rod. Proper fitment and alignment of the piston body and its associated clips are necessary to maintain cylinder compression and support the reciprocating motion required for engine power delivery.
