Gearbox Input Shaft Speed Sensor

The dual part numbers are 4410371210 and 67013072. It is specially designed for Shaanxi Auto DeLong X5000 heavy trucks equipped with Fast AMT automatic transmission. It is made of high-strength flame-retardant engineering plastic through precision injection molding, closely fitting the original gearbox installation interface. It can accurately collect input shaft rotation speed signals and transmit real-time data to the vehicle control unit, effectively solving gear shifting delay, shifting jitter and gearbox fault alarm caused by signal loss or sensor failure. Moreover, it is equipped with a built-in high-sensitivity magnetic induction chip with stable signal output and strong anti-interference ability against electromagnetic interference from vehicle circuits. It comes with an integrated blue silicone sealing ring and original positioning support, making installation convenient, tight and leak-proof.

① Applicable vehicle modelsSuitable for Shaanxi Auto DeLong X5000 heavy trucks. It covers logistics tractors, bulk cargo transport vehicles and engineering transport trucks equipped with Fast Intelligent AMT automatic transmission, and is compatible with the modified models of the same platform.② Adaptation SystemIt precisely matches the original Fast AMT gearbox input shaft assembly and gearbox housing system. It is fixed using original position mounting holes and positioning lugs, without the need for drilling, cutting or any gearbox modifications. It can be installed and used immediately.③ Original Factory Reference NumberCorresponding to dual OE Numbers: 4410371210 (WABCO original part number) / 67013072 (Fast supporting part number). The mold was precisely manufactured strictly according to the original factory data to ensure accurate interchangeability of the parts.④ InterchangeabilityManufactured in accordance with OEM size standards, including installation hole spacing, probe insertion depth, plug outline and sealing ring size all being consistent with the original vehicle. It can be directly replaced with the original gearbox speed sensor assembly, significantly reducing maintenance and adjustment time and lowering labor costs.⑤ Additional ServicesBased on the year of your vehicle model and AMT gearbox version, we can provide installation compatibility verification. In addition, we will also provide guidance on disassembly and assembly steps as well as a list of matching sealing accessories. Our technical support covers the entire installation process to help avoid problems such as signal distortion, oil leakage or fault codes triggered by incompatible parts or improper installation.

The sensor shell is made of high-strength flame-retardant PA66 engineering plastic through injection molding, featuring excellent high-temperature resistance, oil resistance and aging resistance. It can adapt to long-term high-temperature working environments inside the gearbox and erosion from gear oil. The internal induction component adopts imported high-sensitivity magnetic chip, with stable signal acquisition and strong anti-electromagnetic interference performance. The middle sealing part is an integrated blue silicone rubber ring, which maintains stable elasticity under long-term temperature changes to prevent gear oil leakage. The fixed support adopts a reinforced rib structure design, which is unlikely to crack or loosen under long-term vehicle vibration, comprehensively balancing the sealing functionality and signal detection precision.

The surface of the sensor shell is treated with insulation anti-oil coating, which has excellent anti-corrosion and anti-aging resistance, effectively resisting long-term erosion from high-temperature gear oil, dust and road debris. The terminal plug is made of galvanized metal inserts, ensuring stable signal transmission and preventing rust-induced poor contact and signal interruption. The probe edge of the sensor is formed by arc-shaped chamfering mold, resulting in a smooth surface without burrs, which will not scratch the gearbox inner mounting hole during installation and effectively prevent oil seepage at the fitting gap.

Injection molding and chip welding assembly are completed by using advanced fully automatic equipment. The core processes are carried out in a constant temperature and humidity dust-free workshop, which effectively eliminates internal stress in the plastic shell and ensures uniform and stable chip welding quality, eliminating hidden troubles such as signal interruption caused by loose welding points. The key installation size, probe length and plug matching dimension are inspected and controlled in detail by special inspection tools for each piece, ensuring 100% precise fit with the original Fast AMT gearbox without any secondary adjustments. Before each finished product leaves the factory, it undergoes 100% comprehensive inspection, covering appearance defect detection, real-time signal test, high-low temperature cycle test and oil leakage sealing test. Each batch of products is subject to full inspection and screening in accordance with OEM standards to ensure that the assembly accuracy, signal stability and gearbox adaptability meet the requirements in all aspects.
