Cylinder liner for Perkins

The cylinder liner with part number 89042190 functions as the internal sleeve for the engine cylinder. It provides a controlled surface for the piston to travel within the engine block during the combustion cycle. This component is engineered to maintain a precise seal with the engine block and assists in the transfer of heat away from the combustion chamber to the cooling system, which helps maintain stable operating temperatures.

This component is compatible with specified Perkins engine configurations. It is manufactured to meet the dimensional requirements necessary for proper fitment within the engine block. The internal surface is finished to facilitate the retention of a lubricating oil film, which supports the movement of the piston and piston rings during operation.

Cylinder liners act as a replaceable wear surface for the engine block. By housing the piston, the liner contains the pressure generated during the power stroke and provides a stable guide for the reciprocating assembly. Over time, these components are replaced during engine overhauls to restore compression and prevent oil consumption issues caused by surface wear.
