Cylinder liner for Perkins

The cylinder liner with part number 31358357 serves as a protective sleeve within the engine block. It provides the internal cylindrical surface for the piston and piston rings to travel against during the combustion cycle. By separating the piston assembly from the engine block, it manages the thermal transfer between the combustion gases and the cooling system while maintaining the necessary seal for compression.

This component is compatible with a range of Perkins engines found in agricultural equipment, construction machinery, and industrial power generation units. It is engineered to meet the specific dimensional requirements of the block to ensure proper fitment and heat dissipation. Proper installation of this liner is necessary to maintain the internal pressure and oil control required for engine operation.

Cylinder liners are used in internal combustion engines to provide a replaceable wear surface for the piston. They facilitate the movement of the piston assembly while protecting the engine block from the direct mechanical friction and thermal stresses generated during operation. By housing the piston, the liner helps maintain the structural integrity of the cylinder assembly and ensures efficient heat transfer to the surrounding coolant passages.
