Cylinder liner for Caterpillar D315

The cylinder liner, part number 89305110, acts as the inner wall of the engine cylinder in the Caterpillar D315. It creates the chamber where combustion occurs and provides a controlled surface for the piston to travel along during its stroke. By housing the piston, the liner maintains the necessary seal for compression and manages the transfer of heat from the combustion process to the engine cooling system.

This component is engineered for the Caterpillar D315 model. It is designed to meet the specific dimensional and functional requirements of this engine type to ensure proper fitment within the engine block. Proper installation of the liner is necessary to maintain the integrity of the cylinder assembly and to support the reciprocating motion of the engine components.

In internal combustion engines, cylinder liners are used to define the cylinder bore. They provide a replaceable surface that withstands the mechanical and thermal stresses generated by the piston and combustion gases. By maintaining a consistent bore diameter, the liner helps ensure efficient engine operation and proper oil control within the cylinder.
