51541056021 MAN SG Compatible Cylinder Liner

What does a cylinder liner do?

This compressor cylinder liner functions as the critical surface within the compression chamber where the piston travels. It is essential for maintaining proper air pressure and preventing leakage within the air brake system. Built with high-strength components, it provides the necessary durability to withstand continuous friction and thermal cycles during heavy-duty operation.

Vehicle and engine compatibility

This component is specifically compatible with MAN SG 260 and 310 models. It serves as a vital replacement part to restore the pressure-generating capacity of the compressor without requiring a complete unit replacement. Consult your authorized distributor for precise fitment confirmation.

Installation and maintenance

When installing this liner, technicians should ensure the cylinder bore is free of debris and follow specific torque requirements to prevent uneven wear. Proper assembly of the cylinder liner and piston rings is critical to prevent air leakage or oil consumption issues in the braking system.

Troubleshooting guidance

Monitor compressor performance for signs of pressure loss or increased oil consumption, which may indicate that the liner surface has reached its wear limit.
