Cylinder liner for Mercedes-Benz OM407

The cylinder liner, part number A4070110610, acts as the internal sleeve for the engine block in Mercedes-Benz OM407 and OM409 power units. These engines are commonly found in heavy-duty trucks, buses, and industrial machinery, including various crane applications. The component provides a precise sliding surface for the piston assembly while protecting the engine block from direct contact and wear. By facilitating heat dissipation from the combustion chamber, it helps maintain thermal stability during operation. The internal surface is machined to specific tolerances to ensure proper oil retention and an effective seal with the piston rings, which is necessary for maintaining engine compression and managing oil consumption.

This component is compatible with Mercedes-Benz OM407 and OM409 engine models. It is designed to fit directly into the engine block as a replaceable wear surface. Proper installation of this liner is necessary to restore engine efficiency and ensure the mechanical integrity of the cylinder assembly. When the internal diameter of the cylinder shows signs of excessive wear or scoring, replacing the liner allows for the restoration of the original clearance between the piston and the cylinder wall without requiring a full engine block replacement.
