Cylinder liner for Perkins T4.40

The cylinder liner, part number 14-025380-00, acts as a cylindrical insert within the engine block of the Perkins T4.40. It provides the internal surface upon which the piston slides during its reciprocating motion. By serving as a replaceable wear surface, the liner protects the engine block from the friction and movement of the piston and piston rings. It also plays a role in maintaining the seal of the combustion chamber to support proper compression levels during engine operation.

This component is compatible with the Perkins T4.40 engine, which is frequently found in agricultural machinery, construction equipment, and industrial generators. The liner is manufactured to meet the specific dimensional requirements of the T4.40 engine block to ensure a correct fit and proper heat dissipation. Proper installation of this liner is necessary to maintain the internal tolerances of the engine and to prevent issues such as loss of power or increased oil consumption.

In internal combustion engines, cylinder liners are used to define the cylinder bore and manage heat transfer from the combustion process to the cooling system. They allow for the restoration of the cylinder wall surface without replacing the entire engine block.
