Cylinder liner for Mercedes-Benz OM407

The cylinder liner, identified by part number A4070110910, is a cylindrical component installed within the engine block of Mercedes-Benz OM407 and OM409 engines. It provides the internal surface against which the piston travels, creating a sealed environment necessary for maintaining compression and facilitating efficient combustion within the engine cylinders.

This component is compatible with Mercedes-Benz OM407 and OM409 engine models. It is designed to fit precisely into the engine block to ensure proper alignment and sealing. The inner surface is machined to accommodate the movement of the piston rings and to support effective lubrication during the engine cycle.

In internal combustion engines, cylinder liners act as a replaceable sleeve that manages heat transfer and friction between the piston and the engine block. By providing a consistent bore surface, the liner helps maintain the structural integrity of the cylinder assembly and assists in containing the pressures generated during the power stroke.
