Description

What does a compressor piston do?

This compressor piston and ring set serves as a critical component within the pneumatic air brake compressor system. It is engineered to withstand the intense pressure and thermal cycles inherent in heavy commercial vehicle braking operations, ensuring consistent air delivery and system reliability.

Compatible vehicles and engines

This specific kit is designed for use in Volvo FH16 trucks equipped with D16G engines. It is compatible with Volvo systems, ensuring that the piston diameter and ring arrangement meet the required specifications for optimal sealing and compression performance.

Installation and maintenance

For successful installation, technicians should verify that the 80,00mm diameter matches the cylinder bore exactly. It is essential to check the ring groove arrangement and ensure all clearances align with the manufacturer's service manual during assembly to prevent air leakage or premature wear.

Troubleshooting guide

Maintaining regular inspections of the piston and rings helps prevent pneumatic system failures. If air consumption increases or pressure build-up slows, inspecting these components is a recommended maintenance step.

OE cross-reference

7000 801 100 (Compressor Piston & Ring) is the equivalent of the Volvo OE number. This part directly replaces Volvo OE number 21136656.
