Cylinder liner for Caterpillar

The cylinder liner, identified by part number D336/D, serves as the internal sleeve for the engine block in Caterpillar heavy machinery. It provides the primary sliding surface for the piston assembly, facilitating the reciprocating motion required for internal combustion. By forming the cylinder wall, this component maintains the necessary seal for compression and assists in the transfer of heat from the combustion chamber to the engine cooling system.

This component is engineered for specific Caterpillar engine configurations. Proper installation ensures a precise fit with the piston rings, which is necessary to maintain pressure and prevent the bypass of combustion gases. Maintaining the integrity of the cylinder liner surface is important for engine efficiency and preventing oil consumption issues.

Cylinder liners are used in internal combustion engines to provide a replaceable wear surface for the piston. They allow for the restoration of the cylinder bore without replacing the entire engine block. In heavy machinery applications, these liners are subjected to high thermal loads and mechanical friction during operation.
