DZ612600130390 Single Cylinder Compressor

DZ612600130390 is a single-cylinder air-cooled compressor, the core power component of heavy-duty truck braking systems, mainly for SHACMAN WD615 series engines. It converts engine mechanical energy into gas pressure energy, supplying stable compressed air (0.7-0.8MPa) for service braking, parking braking and auxiliary air needs (tire inflation, pneumatic wipers). With single-cylinder piston structure and air-cooled design, it adapts to high-temperature, high-load engine conditions, ensuring sensitive braking response, avoiding failure from insufficient air pressure, and safeguarding heavy trucks in long-haul, mining and engineering scenarios.

①Applicable Vehicles: SHACMAN Delong F3000/X3000/New M3000, Aolong; SINOTRUK HOWO, STEYR, HOAHAN with WD615 series diesel engines.

②Adaptable System: Original braking air circuit, seamlessly connecting to air reservoirs, dryers, brake valves, compatible with original belt drive and mounting bracket.

③OE Reference Number: DZ612600130390

④Interchangeability: Matches original installation dimensions and interfaces, pulley groove and mounting holes aligned precisely. No bracket modification or belt tension adjustment needed, directly replacing original compressor.

⑤Value-added Service: Verifies adaptability via VIN/engine model, provides pulley alignment and air interface sealing guidance, avoiding pressure shortage or excessive belt wear.
