Cylinder liner for Deutz BF4M1013EC

The cylinder liner, part number 0420 0255, functions as a replaceable internal surface for the engine block. It creates a controlled environment for the piston and ring assembly, managing the friction generated during the combustion cycle. By serving as a sacrificial component, the liner protects the engine block from the abrasive effects of piston movement, high combustion pressures, and thermal stress. This design allows for engine maintenance and restoration without requiring the replacement of the entire engine block.

This component is engineered for the Deutz BF4M1013EC engine and is utilized in heavy equipment, including the Tadano GT-550E-1-00102 TC-425-1 crane. The part is manufactured to the specifications required for these specific engine configurations to ensure proper fitment and sealing. Proper installation of the liner is necessary to maintain the integrity of the cylinder assembly and prevent issues such as compression loss or excessive oil consumption.

In internal combustion engines, cylinder liners are installed within the block to provide a consistent bore surface. They are machined to specific tolerances to facilitate the movement of the piston rings and to maintain an effective seal against combustion gases. The interior surface is typically finished to ensure adequate oil retention for lubrication.
