Cylinder liner for Perkins

The cylinder liner 31358308 serves as the internal surface of the engine cylinder where the piston travels. It acts as a replaceable interface between the piston rings and the engine block, managing the friction and heat generated during the combustion cycle. This component is engineered to maintain a precise seal for compression and to facilitate efficient engine operation.

This part is designed for use in specific Perkins diesel engine configurations. It features a machined internal surface finish to support proper lubrication and ring seating. Proper maintenance of the cylinder liner is necessary to prevent compression loss and to manage oil consumption within the engine assembly.

In internal combustion engines, cylinder liners provide a renewable wear surface for the piston assembly. By housing the piston and rings, the liner protects the main engine block from direct contact and thermal stress. This design allows for the restoration of engine tolerances during overhauls without requiring the replacement of the entire engine block.
