1700 040 002 KNORR-BREMSE Compatible Single Cylinder, Air Compressor

The high-strength components of this single cylinder air compressor are engineered to provide consistent pneumatic pressure for heavy commercial vehicle braking systems. Designed for durability under high-pressure conditions, this unit ensures reliable operation within the air brake system architecture. It features a water-cooled design to maintain optimal thermal stability during continuous operation.

1700 040 002 is the OE-equivalent single cylinder air compressor used in KNORR-BREMSE (LP3861, SEB01152X00) and RENAULT TRUCKS (5000691934, 5001857409, 7485003208) systems. This component is precision-engineered to meet the strict technical requirements of the original equipment for heavy-duty truck applications.

Workshop technicians should note the specific technical dimensions during installation, including the Ø78.00 mm cylinder bore and the M26x1,5 air port specifications. The unit is water-cooled (W), requiring proper connection to the water inlet and outlet ports (M18x1,5) to prevent overheating. Regular maintenance and checking of the water-cooled valve plate integrity are recommended to ensure long-term service reliability in professional fleets.

Proper assembly requires verifying the through-drive compatibility and ensuring all port connections are tightened to manufacturer specifications to prevent air or water leaks. This single cylinder unit is optimized for heavy-duty vehicle service environments where consistent air supply is critical.
