20846000 Volvo B13R D13B Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor is engineered to provide high-capacity air generation for heavy commercial vehicle braking systems. By utilizing a dual-cylinder configuration, it ensures a faster air supply to meet the high demands of heavy-duty operations. The unit is designed with heavy-duty grade materials to withstand intense thermal and mechanical stress during continuous service.

Compatible vehicles and engines

This specific model is fitted to Volvo B13R trucks featuring D13B engines. It is designed to function seamlessly within the vehicle's pneumatic system, providing the necessary air volume for reliable braking performance. The integration of an ESS feature ensures optimized air management during engine operation.

Installation and maintenance

For installation, technicians should note the water-cooled configuration, which requires connection to the engine cooling circuit via the M16x1,5 inlet and outlet ports. The unit features a Ø85.00 mm cylinder bore and a 56 mm stroke. Ensure all port connections, including the M26x1,5 air outlet, are torqued to specification to prevent leaks.

Troubleshooting and service

Regular inspection of the water-cooled valve plate and port seals is recommended to maintain optimal compression efficiency. Checking the unloader port and drive gear alignment during routine maintenance can prevent premature wear in the pneumatic system.
