Short block engine for Mercedes-Benz OM441

This short block engine assembly, identified by part number 441926, serves as the foundational core for the Mercedes-Benz OM441 engine. The unit consists of the cylinder block, crankshaft, connecting rods, and pistons. It is supplied without cylinder heads or other upper engine components, allowing for the reuse of existing heads or the installation of new ones during a major engine overhaul or reconstruction project.

The component is engineered specifically for the Mercedes-Benz OM441 engine model. By providing the primary rotating assembly and block structure, this unit facilitates the restoration of the mechanical heart of the machine. It is suitable for maintenance scenarios where the upper valvetrain and cylinder head assemblies remain serviceable or are being managed as separate repair items.

A short block acts as the structural base of an internal combustion engine, housing the primary moving parts that convert reciprocating motion into rotational power. By replacing the core assembly, maintenance teams can address internal wear or damage to the block, pistons, or crankshaft while maintaining the existing top-end configuration of the engine.
