21136656 Compressor Piston & Ring for Volvo FH16

What does a compressor piston do?

This compressor piston and ring set plays a critical role in the air brake compressor assembly, facilitating the compression of air required for heavy commercial vehicle braking systems. Manufactured from high-strength components, these parts are designed to withstand the intense thermal and mechanical stresses found in heavy-duty environments.

Vehicle and engine compatibility

This specific kit is compatible with Volvo FH16 trucks equipped with D16E engines. It is engineered to match the precise requirements of the air brake system, ensuring efficient air production for the vehicle's pneumatic circuits. Check the compatibility list.

Installation and maintenance guidance

When performing maintenance or overhaul, technicians should verify the piston diameter and the condition of the cylinder liner. Proper installation requires checking the ring end gap and groove clearances to prevent premature wear or binding. Ensuring the piston pin diameter matches the connecting rod bushing is also vital for long-term durability.

Selection and fitment considerations

Selecting the correct piston diameter is essential to ensure a proper seal within the liner. If the liner has been machined, oversize options may be required, but for standard applications, this 80.00mm diameter component provides a direct fit for specified Volvo engine configurations.

OE cross-reference
