1628593 SP1 Compressor for Volvo FL12 TD123 Engine

What does a twin cylinder compressor do?

This water-cooled twin cylinder compressor is a critical component within the air brake system of heavy commercial vehicles, providing the necessary compressed air for braking and pneumatic functions. Designed for high-demand environments, this unit utilizes two piston-cylinder assemblies to ensure rapid reservoir filling and consistent pressure delivery. The water-cooled design maintains thermal stability, making it suitable for sustained high-load operations.

Vehicle and engine compatibility

This specific unit is compatible with Volvo FL12 trucks equipped with TD123 engines. It features a through-drive configuration and is engineered to match the specific requirements of heavy-duty engine configurations. The unit includes a water-cooled valve plate and an ESS feature to optimize pneumatic performance under varying load conditions.

Installation and technical specifications

For proper installation, technicians should verify that the water inlet (M16x1,5) and outlet ports align with the existing engine coolant circuit. The air outlet port is M26x1,5, and the air unloader port is M22x1,5. Given the 23 KG weight and precision tolerances like the Ø88.00 bore, ensuring correct mounting torque and coolant flow is essential for long-term reliability.

Replacement guidance

When replacing this component, always cross-reference the mounting flange and drive gear to ensure a perfect match with the removed unit.
