Cylinder liner for Scania DS/D SC901

This cylinder liner, part number 89385110, serves as the internal surface of the engine block where the piston operates. It acts as a replaceable wear surface that protects the engine block from the friction and heat generated during the combustion process. By maintaining a precise internal diameter and surface finish, this component ensures an effective seal with the piston rings to maintain proper compression and manage oil consumption within the engine.

The component is engineered for fitment in Scania DS/D SC901 engines. Proper installation of this liner is necessary to prevent loss of power and to protect the integrity of the engine block during operation. Maintaining the correct tolerances between the liner and the piston assembly is required for the engine to function according to its original design specifications.

Cylinder liners are used in internal combustion engines to form the cylinder bore. They allow for the restoration of the engine block without requiring a full block replacement, as the liner can be removed and replaced once it reaches its wear limit. This design helps maintain the necessary clearance for the piston and rings throughout the service life of the engine.
