Cylinder liner for Scania D7C

The cylinder liner, part number 14-480040-00, acts as the internal sleeve for the engine block in Scania D7C engines. It provides a precise surface for the piston to travel within, ensuring the integrity of the combustion chamber. By housing the piston, this component maintains the necessary compression levels required for consistent engine power and efficiency. It also plays a role in transferring heat away from the combustion area to the cooling system of the engine block.

This component is compatible with the Scania D7C engine series. It is manufactured to meet the specific dimensional requirements of the engine block to ensure a proper seal and fitment. The liner is installed directly into the engine block, shielding the surrounding metal from the direct heat and friction generated by the reciprocating movement of the piston and rings.

In heavy machinery engines, cylinder liners are used to define the cylinder bore. They allow for the restoration of the engine's internal dimensions during an overhaul without the need to replace the entire engine block. The liner surface is finished to facilitate proper lubrication and ring seating, which helps manage oil consumption and prevents blow-by during the power stroke.
