7000 751 100 Volvo DAF Compressor Piston & Ring

What does a compressor piston and ring do?

This compressor piston and ring set is engineered to restore the compression efficiency of heavy-duty air brake compressors. These high-strength components are vital for maintaining the pneumatic pressure required for safe braking operations in commercial vehicle systems.

Compatible vehicles and engines

This assembly is compatible with various Volvo models including the F7, FL, B10M, B12, F12, FL10, NL10, F10, FL7, NL12, FL12, N10, B10, F16, FH12, N12, B10B, NH12 and NL12. It also serves DAF F95 and F75/F85 models. These parts are also fitted to Renault Trucks, Scania, and MAN trucks.

Installation and maintenance

When performing maintenance on the air compressor system, technicians should verify the piston diameter and cylinder liner condition. This Ø75,00mm (STD) kit is designed for standard installations where liner machining has not been performed. Ensuring correct groove clearance during installation is essential for optimal sealing.

Maintenance guidance

Regular inspection of the piston rings helps prevent air leakage within the compressor assembly. For reliable service life in heavy commercial vehicle applications, always match the component to the specific engine configuration such as the Volvo TD120 or D10A series.
