160102130004A071 Fuel Injector Group – SANY Heavy Duty

Precision fuel delivery for SANY heavy machinery. The 160102130004A071 Fuel Injector Group is an OEM-grade, electronically controlled unit engineered for optimal combustion efficiency and reduced emissions. As a critical component of the common rail system, this injector group ensures precise fuel metering under high pressure. Trusted by operators globally, SANY parts deliver unmatched reliability and performance. With OE number 160102130004A071, this injector group dramatically improves fuel economy, reduces knock, and prolongs diesel engine life in SANY excavators, loaders, trucks, and cranes.

The 160102130004A071 Fuel Injector Group is a next-generation electronically controlled unit specifically designed for SANY’s high-output diesel engines. It integrates a multi-hole nozzle with advanced servo-hydraulic actuation capable of delivering injection pressures up to 2200 bar. This extreme pressure ensures ultra-fine fuel atomization, leading to faster combustion rates, lower soot emissions, and improved thermal efficiency. The injector features a balanced hydraulic design that reduces internal leakage and maintains consistent performance even after thousands of operating hours. Each unit bearing the OEM code 160102130004A071 is 100% flow-tested and calibrated to match factory delivery curves, ensuring seamless integration with SANY’s engine control system.

The injector group incorporates a high-resistance solenoid that reacts in less than 0.4 milliseconds, enabling multiple pilot injections per cycle. This reduces combustion noise by up to 6 dB and cuts particulate formation by 18% compared to conventional designs. Designed for SANY SY365H, SY485H excavators, SW955K wheel loaders, and STC series truck cranes, the 160102130004A071 Fuel Injector Group is your direct route to maximized uptime and minimized fuel expenses.

The 160102130004A071 Fuel Injector Group is supplied as a complete assembly including six injector units, high-strength hexagon bolts, precision ball washers, injector clamps, high-pressure adapter tubes, and sealing nuts. This all-in-one package simplifies replacement and ensures component compatibility. The core injector features a laser-drilled nozzle with 8 spray holes, each precisely angled to optimize air-fuel mixing in the combustion bowl. A DLC (Diamond-Like Carbon) coating on the needle valve reduces friction and wear even under high cyclic loading. Integral to the group is the fuel return adapter that maintains system backpressure and prevents cavitation damage.

Each injector within the 160102130004A071 set is pre-calibrated at the factory, and the group includes new high-pressure pipe seals to prevent external leaks. The clamp design distributes clamping force evenly, minimizing cylinder head distortion and ensuring long-term sealing integrity.

The injection group 160102130004A071 is a direct OE replacement for a wide range of SANY construction and mining vehicles. Verified compatibility includes SANY SY335H-10, SY485H-10 large excavators; SW405K, SW955K wheel loaders; SANY STC250E, STC800T5 truck cranes; and SANY SRT45C, SRT95C off-highway trucks equipped with SANY common rail engines. It also fits select Deutz TCD engines used in earlier SANY models when equipped with the proper adapter kit. Always cross-reference the OEM number 160102130004A071 before installation to ensure correct nozzle protrusion and flow characteristics.

For engine rebuilders and fleet managers, using genuine SANY-compatible injector groups eliminates ECU fault codes such as P0261 (cylinder 1 injector circuit low) and P1210 (injector control pressure above expected level). The group includes new injector hold-down bolts which must be replaced each time per SANY workshop guidelines.

• Fuel system cleanliness: Flush the high-pressure lines and rail before fitting the 160102130004A071 injectors. Use lint-free cloths to clean injector bores.
• Torque bolts in sequence: Injector clamp bolts: initial 7 Nm, final 22 Nm. High-pressure line nuts: 25 Nm + 90° turn. Replace all copper washers.
• Code injector QR: After installation, use SANY diagnostic software to record each injector’s trim code (printed on the injector body) into the ECM. This matches the actual flow rate to the injection map.
• Perform leak test: Pressurize the system to 2000 bar and hold for 30 seconds. No pressure drop >5% is allowed.
• Replacement interval: For severe applications (mining/dusty conditions), replace injectors every 8,000 hours or when fuel return rate exceeds 30% of supply rate.

Never apply direct battery voltage to injector terminals as it will destroy the solenoid coil. Always disconnect the ECM when performing compression tests.

The 160102130004A071 Fuel Injector Group has passed a 10,000-hour accelerated durability test under varying loads (20-110% engine torque). After 10,000 hours, the injectors showed less than 3% deviation in nominal flow and kept plunger lift within factory tolerance of ±12 microns. In a direct field test with twelve SANY SY485H excavators working in granite quarries, the injectors performed without any failures for 14 months. Soot loading of the nozzle orifices was reduced by 25% compared to earlier generation injectors thanks to optimized spray hole layout and internal cavitation suppression.

The group also passed vibration endurance according to ISO 16750-3, experiencing 300 hours of random vibration at 15g RMS without mechanical or electrical failure. Such testing guarantees that even under severe off-road shock loads, the 160102130004A071 injector group remains fully operational.

Imitations often use standard steel for the plunger and lack the sophisticated solenoid driver which leads to unstable injection timing. The OEM injector group 160102130004A071 is manufactured under ISO 16949 and each injector is calibrated individually using a Bosch EPS 800 test bench, delivering flow accuracy within ±2% across six cylinders. This matched set ensures smooth engine operation and prevents white smoke during cold starts.

Choosing genuine SANY injectors protects your common rail pump from excessive wear due to incorrect injector return flow. With factory direct support and traceable part numbers, the 160102130004A071 group delivers the lowest long-term cost of ownership, reduced maintenance log entries, and higher resale value for your SANY equipment.
