Short engine block for Mercedes-Benz OM442

The short engine block assembly, part number 442907, serves as the primary foundation for the Mercedes-Benz OM442 engine. This unit comprises the engine block, crankshaft, connecting rods, pistons, and main bearings. It is supplied without cylinder heads or valve train components, making it suitable for rebuilds where the original cylinder heads remain in operational condition or are being replaced separately. By utilizing this assembly, technicians can restore the mechanical base of the engine to its original configuration.

This component is specifically engineered for the Mercedes-Benz OM442 engine model. It provides a complete bottom-end solution for heavy-duty machinery and vehicle applications requiring a full overhaul of the rotating assembly and cylinder block. The assembly ensures that critical internal clearances and structural integrity are maintained during the engine reconstruction process.

A short engine block provides the essential reciprocating and rotating mass necessary for internal combustion. It houses the cylinders where the power stroke occurs and supports the crankshaft, which converts linear piston movement into the rotational force required to drive the machine transmission or hydraulic systems.
