20382348 Compressor for Volvo VHD D12 engines

What does a single cylinder compressor do?

This single cylinder compressor serves as a critical component within the pneumatic braking system, providing the necessary air pressure for reliable braking performance. Built with high-strength components, this unit is engineered to withstand the intense thermal and mechanical stresses found in heavy commercial vehicle engine environments.

Vehicle and engine compatibility

This specific model is designed for Volvo VHD trucks equipped with D12 engines. It features a water-cooled design to maintain optimal operating temperatures and includes an integrated unloader port (M12x1,5) and ESS feature for enhanced system stability. Consult your authorized distributor for exact fitment verification.

Installation and maintenance guidance

For proper installation, technicians should verify the water inlet and outlet ports (M16x1,5) and ensure the through drive alignment is correct. Maintaining clean cooling lines and checking the M26x1,5 air outlet connections during routine service intervals helps prevent pressure drops in the pneumatic circuit.

Troubleshooting and service tips

Regular monitoring of the swept volume capacity and air delivery helps in early detection of wear. If pressure build-up slows or unloader functionality fluctuates, a professional inspection of the valve plate and piston assembly is recommended to maintain system integrity.
