130104000166B001 Sun Gear Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The sun gear (130104000166B001) is the core driving gear of the planetary transmission system of the reducer. By driving the planetary gears, it amplifies torque and transmits power, directly controlling the speed and power of the equipment’s movement and rotation. It is a precision core component that ensures the stable operation of the transmission system.
This product is made of high-strength alloy, reinforced by forging and quenching, resulting in high hardness and toughness. Its precision-designed, wear-resistant tooth surface withstands heavy-duty impacts and high-frequency fatigue, making it suitable for continuous heavy-duty operations on construction sites. Old sun gears are prone to tooth surface wear, pitting, slippage, and tooth breakage, leading to abnormal transmission noise, insufficient power, and difficulty in travel and rotation. In severe cases, this can cause the reducer to stop and fail. This product is an original factory precision part with accurate tooth profile and standard clearance, allowing for non-destructive replacement of old parts. It is suitable for reducer maintenance, overhauls, and bulk stocking, effectively restoring equipment transmission performance and reducing maintenance costs.
