1157405330 Original Excavator 6HK1 Engine Timer

Part number 115740530 is the original timer provided by ISUZU (Isuzu) specifically for the 6HK1 series diesel engine, usually referring to the fuel injection timing controller or related electronic control unit. This component is the core of the engine electronic control system, and its universal models cover various mainstream medium-sized hydraulic excavators equipped with 6HK1 engines, mainly including Hitachi ZX200-3, ZX270-3, EX200-3, Komatsu PC200-8, PC220-8 and other 20-22 ton models. As an original precision control module, its hardware and internal calibration data are deeply integrated with the engine ECU

This product is an engine electronic control timing unit, with a dark gray cylindrical metal shell and a finely sandblasted surface. It has good heat dissipation, electromagnetic shielding, and rust prevention properties. One end of the casing is equipped with an installation flange and a multi pin electrical interface. Its core is a high-performance processor that accurately calculates and controls the fuel injection advance angle of the fuel injection pump by receiving signals from sensors such as the crankshaft and camshaft, ensuring that the engine can achieve optimal power, economy, and emission levels under different operating conditions.

Installation and matching (professional operation): 1 Safe power-off: Before operation, be sure to disconnect the negative terminal of the battery and wait for 5 minutes. 2. Plug in installation: After disassembling the old parts, install the new timer (115740530) smoothly in place, ensure that the electrical interface is plugged in and locked, and tighten the fixing bolts according to the specified torque. 3. Mandatory programming: It is strictly prohibited to start directly after installation. It is necessary to use a dedicated diagnostic instrument to perform online matching and calibration of the engine ECU, so that the new timer can be recognized by the system and work together.
