7100 702 005 Volvo & Renault Compressor Crankcase

What does a compressor crankcase do?

This compressor crankcase serves as the foundational housing for the internal moving components of an air brake compressor. It provides the necessary structural support and containment for the crankshaft and bearings, ensuring stable rotation and pressure maintenance during operation. Built with heavy-duty grade materials, this component is essential for maintaining the compression performance of the air brake system.

Vehicle and engine compatibility

This part is compatible with Volvo trucks including FH (FH4/FH5), FM, FMX, VNL, B11R, and B13R models featuring D13K, D11K, D13, or D16K engines. It is also fitted to Renault Trucks K, T, and C models with DTI11 or DTI13 engines. Additionally, it is used in Mack Anthem with MP8 engines and is also fitted to Navistar and Dina trucks.

Installation and maintenance

When performing maintenance on the air brake system, ensuring the crankcase is free from hairline cracks or excessive oil contamination is critical. Technicians should verify that all mounting surfaces are clean and that the unit is installed according to service manual specifications to prevent vibration or pressure loss. This component is compatible with Bendix systems.

Maintenance and troubleshooting

Proper selection of a high-strength crankcase prevents premature failure of internal seals and bearings. Regular inspection of the compressor housing during routine service intervals can help identify early signs of wear or leakage before they lead to system-wide pneumatic failure.
