20478166 Volvo FH16 D16C Compressor

What does a single cylinder compressor do?

This air brake compressor serves as a vital component in the pneumatic braking system of heavy commercial vehicles. It is engineered to provide consistent air pressure through a high-strength single cylinder design, ensuring the reliable operation of air brakes and auxiliary pneumatic systems. The unit is built with heavy-duty grade materials to withstand intense thermal and mechanical stress during operation.

Compatible vehicles and engines

Specifically designed for Volvo FH16 trucks equipped with D16C engines, this compressor ensures precise air delivery. The unit features a water-cooled configuration to manage operational temperatures effectively, which is critical for maintaining long-term stability in heavy-duty service environments.

Installation and maintenance

Installation and maintenance should focus on the integrity of the cooling circuit and port connections. Technicians should verify that the M26x1,5 air outlet and M16x1,5 water ports are free of debris and properly seated. Regular inspection of the valve plate and unloader functionality helps prevent system pressure drops.

Troubleshooting and selection

When evaluating replacement needs, check for signs of excessive wear on the cylinder surface or unusual noise during the compression cycle. Maintaining correct coolant levels in the engine cooling loop is essential for the longevity of this water-cooled unit.
