8000 100 001 Mercedes-Benz Connecting Rod & Piston

The compressor connecting rod and piston assembly serves as the mechanical core of the air brake compressor. The connecting rod transmits the crankshaft's rotary motion to the piston, which then compresses air inside the cylinder to generate the pressure required for the pneumatic brake reservoirs. The condition of these components directly influences the compressor's air output, oil consumption, and overall running noise.

This assembly is designed for heavy commercial vehicle applications, including Mercedes-Benz ACTROS MP4/MP5, ANTOS, AROCS, and ATEGO 3 models. It is also compatible with Mercedes-Benz UNIMOG, Setra Series 400, and various Mercedes-Benz OH and ATEGO 2 configurations. These parts are engineered to meet the rigorous demands of OM 936, OM 934 LA, and OM 904 LA engine series.

For workshop technicians performing an overhaul, renewing the piston and rings together with the connecting rod is often the recommended approach to ensure optimal compression. When inspecting these parts, check for signs of excessive wear on the piston pin or bushing to prevent system failure. Maintenance of these high-strength components is vital for maintaining consistent air pressure throughout the pneumatic system.

Consult your authorized distributor to ensure correct fitment for your specific engine configuration.
