8980148310 Original Isuzu 4HK1 6HK1 Engine Sensor for Excavator

Part number 8980148310 (also known as 898014-8310) is an original camshaft position sensor (also known as an eccentric shaft sensor) specifically designed for Isuzu 4HK1 and 6HK1 series electronic fuel injection diesel engines. This sensor is widely used in multiple Hitachi ZX series hydraulic excavators. According to publicly available accessory information, the main compatible models include Hitachi ZX200-3, ZX210-3, ZX240-3, etc. It is also suitable for construction machinery such as the Case CX360B equipped with the same engine. This part is a genuine original product, and its universal part number is 8980148310 or 898014-8310. It must be verified based on this during procurement. Due to differences in sensor installation dimensions, electrical interfaces, and signal characteristics among different engine models, it is ensured that the engine control unit (ECU) can accurately read the camshaft phase signal to ensure normal engine start-up and operation.

This sensor is one of the core signal input components of the engine electronic control management system (ECU). Its core function is to monitor the precise position and speed of the camshaft in real time, and convert this signal into an electrical signal to be transmitted to the ECU for accurate calculation of fuel injection timing, ignition sequence, and valve timing. It is the key to achieving efficient, smooth, and low emission operation of the engine. As an original component, it usually adopts Hall effect or magneto electric principle, which has the characteristics of fast response speed, high signal accuracy, and strong anti-interference ability. It contains precision sensing components and signal processing circuits inside, packaged in a high temperature resistant, oil proof, and dust-proof housing, which can adapt to the harsh environment of high temperature, vibration, and oil pollution in the engine compartment.

The maintenance core of this sensor lies in regular inspection, maintaining cleanliness, ensuring reliable connection, and standardized diagnosis and replacement. For Hitachi ZX200-3 and other models, fault code 636-7 usually points to abnormal camshaft position sensor signal. Cleaning and Inspection: After disassembling the sensor, check whether its sensing probe is adsorbing metal debris or oil sludge, and clean it with anhydrous alcohol. Before installation, ensure that the installation holes are clean and free of foreign objects. Replacement and installation: When installing a new sensor, it is necessary to use a torque wrench to tighten the fixing bolts according to the original factory specified torque value (usually 8-20 N · m) to avoid damaging the sensor due to over tightening or causing signal misalignment due to over loosening.
