8000 850 008 Volvo & Renault Compressor Connecting Rod & Piston

What does a compressor connecting rod and piston do?

This compressor connecting rod and piston group plays a vital role in the pneumatic compression cycle of the air brake system. The connecting rod transmits motion from the crankshaft to the piston, which in turn compresses air within the cylinder to generate the necessary pressure for the braking reservoirs. This component group is essential for maintaining consistent air output and minimizing oil consumption in heavy-duty applications.

Compatible vehicles and engines

This assembly is compatible with several heavy commercial vehicle models, including Volvo FH, FM, FMX, VHD, and VNL series, as well as Renault Trucks Premium, Magnum, and Kerax models. It is also fitted to Mack Granite and Pinnacle trucks. These components are designed to match the performance requirements of WABCO systems found across these diverse engine configurations.

Installation and maintenance

For optimal performance, technicians should inspect the connecting rod and piston assembly during routine pneumatic system maintenance. Signs of wear or increased running noise may indicate a need for replacement. When selecting parts, ensure the component matches the specific requirements of the engine type, such as the D13 or DXi series engines common in these vehicles.

Troubleshooting guidance

Maintaining high-strength components within the compressor helps prevent system pressure drops and ensures reliable braking performance for fleet operators.
