Short block engine for Mercedes-Benz

The short block assembly, identified by part number 402987, serves as the primary mechanical foundation for the engine. It consists of the engine block, crankshaft, connecting rods, and pistons with their respective rings. This configuration is supplied without the cylinder heads, camshafts, fuel injection systems, water pumps, or intake and exhaust manifolds, allowing for the reuse of existing compatible components during a rebuild.

This assembly is designed specifically for Mercedes-Benz engine applications, which are commonly utilized in heavy trucks, buses, commercial vehicles, and industrial machinery. The components are manufactured to meet the specific dimensional and tolerance requirements established by Mercedes-Benz for their engine series.

A short block provides a base for restoring engine power and mechanical integrity following internal failures. By replacing the primary rotating and reciprocating assembly, maintenance teams can establish a solid foundation for the engine while retaining functional external accessories. This approach facilitates the restoration of the engine to its original operating specifications.
