Engine overhaul kit for Scania D12C

The 89-123200-42 engine overhaul kit provides a complete set of internal components for the Scania D12C diesel engine. This assembly includes pistons, cylinder liners, piston rings, connecting rod bearings, main bearings, and a full set of gaskets and seals. It is used to facilitate a major repair or reconstruction of the engine block when internal components have reached their service limits. By replacing these parts, the engine can be returned to its specified operating tolerances.

This kit is compatible with the Scania D12C engine series, which is commonly found in heavy-duty trucks and industrial machinery. The components are designed to fit the specific dimensions and requirements of the D12C block. Using a complete kit ensures that all reciprocating and sealing parts are matched for a proper assembly.

An engine overhaul kit serves to restore compression and combustion efficiency within the cylinder assembly. The pistons and liners manage the pressure generated during the power stroke, while the rings and seals maintain the necessary containment of oil and combustion gases. Replacing these components as a set is standard practice during a major engine service to ensure consistent clearance and wear patterns across all cylinders.
