160102130003A004 SANY Crankcase – Foundation of Heavy‑Duty Diesel Engine Reliability

Precision foundation for SANY diesel engines. The OEM 160102130003A004 Crankcase is the structural core of SANY D12 and D09 heavy‑duty engines. This rigid casting houses the crankshaft and bearings, maintaining precise alignment under extreme loads. Trusted by service professionals worldwide, SANY parts deliver unmatched dimensional accuracy and durability. With part number 160102130003A004, this crankcase is essential for engine overhauls, structural repairs, and complete rebuilds, protecting SANY powerplants from misalignment, vibration damage, and premature bottom‑end failure.

The 160102130003A004 Crankcase is the precision‑machined casting that forms the foundation of SANY D12 and D09 diesel engines. It encloses the crankshaft, main bearings, and connecting rods, maintaining exact alignment of the crankshaft centerline and bearing bores under extreme torsional forces and vibration.

The D12 engine, developed with DEUTZ, has a displacement of 12.12 liters and six cylinders. It delivers 360 kW (490 hp) at 1,900–2,100 rpm and a maximum torque of 2,150 Nm. The D09 engine is a 9‑liter six‑cylinder unit producing 280–380 hp with 1,500 Nm of torque at 1,000–1,500 rpm.

The crankcase features integrated oil galleries that direct pressurized lubricant to the main bearings, connecting rod bearings, camshaft bearings, and turbocharger supply ports. This internal oil routing eliminates external plumbing and ensures consistent oil flow at all engine speeds.

As documented in the SANY Crankcase Assembly catalog, the 160102130003A004 Crankcase works with corehole plugs, pulling rivets, hexagon screw plugs, and threaded socket head cap plugs. These components maintain leak‑proof fluid containment and structural integrity under all operating conditions.

The closed crankcase ventilation system manages blow‑by gases and maintains proper crankcase pressure, preventing oil seal leakage and reducing emissions. Vented gases are routed to the intake system, where they are re‑burned in the combustion chambers.

High‑strength fasteners secure the main bearing caps to the crankcase saddles with precise clamping force. The 160102130003A004 Crankcase is manufactured from high‑grade alloy cast iron that resists thermal distortion and maintains bolt retention under high combustion pressures.

Surface finishes on bearing bores, deck surfaces, and mounting faces are machined to extremely tight tolerances. This ensures that the cylinder head, oil pan, and gear covers seal correctly and remain leak‑free throughout thousands of operating hours.

The D12 engine meets Euro VI emission regulations through its 1,800 bar common‑rail injection system. It achieves a brake‑specific fuel consumption of 187 g/kWh — markedly lower than competitors — directly reducing operating costs across a fleet of SANY trucks and equipment.

The D12 can start in just 2 seconds at 3,000 m altitude and -20°C without power loss. Its split‑type cylinder head minimizes engine noise, and the patented TOP‑Down cooling system quickly reduces fluid temperature for improved efficiency.

The D09 engine uses Bosch fuel system, starter, and alternator, ensuring premium component quality. Based on confidence in the D12, SANY offers a five‑year, mileage‑unlimited warranty — a testament to the durability of this engine platform.

The D12 is widely used in SANY truck mixers, dump trucks, truck‑mounted pumps, and Kingway 435 heavy trucks. D09 engines are fitted in over 70% of SANY mixer trucks and rollers, and in 100% of truck‑mounted pumps.

Replacing a damaged crankcase requires complete engine disassembly. The 160102130003A004 must be handled with extreme care: bearing bores must be cleaned, inspected, and verified within SANY tolerance. Main bearing bolts must be replaced and torqued to the specified angle.

Genuine SANY crankcases ensure exact bore dimensions, wall thicknesses, and oil passage designs. Aftermarket crankcases often lack correct bolt hole alignments, leading to low oil pressure, component misalignment, and shortened engine life.

Using genuine SANY components ensures that warranty claims on major engine systems will not be denied, guaranteeing long‑term reliability of your SANY equipment investment.
