85000117 Compressor Compatible with Volvo B12

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component in the pneumatic braking system, providing the necessary air pressure for reliable deceleration and system operation. Built with heavy-duty grade materials, this unit is designed to withstand the high-temperature and high-pressure environments typical of heavy commercial vehicle engines.

Compatibility and technical specifications

This specific model is compatible with Volvo B12 engines. It features a water-cooled design with M16x1,5 inlet and outlet ports, an M26x1,5 air outlet port, and an M12x1 air unloader port. The unit includes an ESS feature and a water-cooled valve plate to optimize thermal management during operation.

Installation and maintenance guidance

For proper installation, technicians should ensure that the water inlet and outlet connections are secure and that the Ø35 air inlet port is free from debris. Given the 20.8 KG weight and through-drive configuration, correct mounting torque is essential to prevent vibration-related fatigue in the assembly.

Operational troubleshooting

Regularly check the air unloader port and cooling lines to maintain optimal performance. If air pressure fluctuations occur, inspect the valve plate and cooling flow to ensure the unit is operating within its intended technical parameters.
