Short engine block for Mercedes-Benz

The 401972 short engine block serves as the primary foundation for engine overhauls and major repairs in Mercedes-Benz heavy machinery and industrial cranes. This pre-assembled unit consists of the engine block, crankshaft, connecting rods, pistons, and bearings. It is supplied without cylinder heads or valve train components, allowing technicians to integrate existing or new cylinder heads during the assembly process.

This component is designed to maintain factory-specified tolerances and alignment for the internal rotating assembly. By utilizing a pre-assembled short block, maintenance teams can streamline the engine restoration process and ensure that critical internal clearances are managed correctly before final assembly. This unit is manufactured by Mercedes-Benz.

A short engine block functions as the mechanical heart of the propulsion system, housing the reciprocating parts that convert combustion energy into rotational force. It provides the necessary structural support for the cylinder heads and external engine accessories while containing the oil and coolant passages required for operation.
