1697707 Piston Compatible with Volvo B12 TD120

What does a compressor piston do?

This compressor piston is a critical component within the pneumatic air brake compressor system, responsible for maintaining the compression stroke necessary for reliable braking performance. Manufactured with high-strength components, it ensures durability under the intense pressure and thermal cycles typical of heavy commercial vehicle operation.

Vehicle and engine compatibility

This specific part is compatible with Volvo B12 engines, specifically the TD120 series. It is engineered to meet the rigorous demands of heavy-duty duty cycles, ensuring the integrity of the pneumatic system. It is also fitted to other heavy commercial vehicles such as Mercedes-Benz, MAN, Scania, DAF, Iveco, Renault Trucks, and BMC.

Installation and maintenance guidance

When performing maintenance, technicians should verify the cylinder bore and pin diameter to ensure a precise fit. Since this is a standard size piston, it should only be used in liners that have not been machined to an oversize diameter. Proper installation requires checking ring groove clearances to prevent air leakage or excessive wear.

Troubleshooting and service tips

For optimal system longevity, inspect the piston and rings during every scheduled compressor service. If signs of blow-by or decreased pressure are detected, this replacement component helps restore full system efficiency. Check the compatibility list.
