Whether you need a new hydraulic pump, engine components, or undercarriage parts, we've got you covered. Our genuine Hitachi parts and reliable aftermarket solutions are designed for durability and performance.
Engine Speed Related Issues
Several Hitachi excavator fault codes are directly linked to engine speed and related sensor abnormalities. These often indicate problems with the engine speed sensor or the engine speed control knob sensor . Addressing these promptly can prevent more severe engine damage and ensure your Hitachi excavator engine operates within optimal parameters.
11100-2: Engine speed abnormal. This suggests an unexpected deviation in the engine's RPM.
11101-3: Engine speed control knob sensor high voltage abnormal. Indicates an issue where the sensor input is too high.
11101-4: Engine speed control knob sensor low voltage abnormal. Points to a sensor input that is too low.
Beyond engine speed, other critical sensors like the pump delivery pressure sensor, pump control pressure sensor, and pilot pressure sensor can trigger various Hitachi fault codes. Furthermore, issues within the ECM sensor system are common and require precise diagnosis. Growshine International offers a wide range of excavator sensor replacements and electrical components for excavators to address these issues.

This ensures the engine maintains optimal operating temperature on models like the Caterpillar 345D excavator .
Injector Drive System Problems
Fault codes related to the injector drive system, specifically codes 651-3 through 656-3, indicate an open circuit in the system, meaning the injector monitor is not receiving an input signal. This is a critical issue as it directly impacts fuel delivery and engine performance. These codes commonly occur in Hitachi Zaxis excavators.
651-3: Injector #1 drive system open, injector 1 monitor no input signal.
652-3: Injector #2 drive system open, injector 2 monitor no input signal.
653-3: Injector #3 drive system open, injector 3 monitor no input signal.
654-3: Injector #4 drive system open, injector 4 monitor no input signal.
655-3: Injector #5 drive system open, injector 5 monitor no input signal.
656-3: Injector #6 drive system open, injector 6 monitor no input signal.

Common Rail and Pressure Limiter Anomalies
Common rail pressure abnormalities are serious and can lead to significant engine issues. Codes 157-0 and 157-2 point to problems within the common rail system , while 633-7 indicates an activated pressure limiter . These are frequently observed in Hitachi EX series excavators.
157-0: Common rail pressure abnormal (level 1), pressure exceeds 185 MPa.
157-0: Common rail pressure abnormal (level 2), level 1 abnormality and pressure exceeds 190 MPa.
157-2: Common rail pressure abnormal (pump overpressure), actual pressure is 40 MPa higher than target.
633-7: Pressure limiter open.
Accurate common rail pressure monitoring and functioning pressure limiters are vital for the proper operation of your Hitachi common rail engine.

Fuel Leakage and Pump Pressure Issues
Fuel system integrity is paramount for excavator operation. Fault codes 1240-1 and 1239-1 indicate fuel leakage, which can severely affect fuel pump pressure and overall engine performance. These issues often lead to a loss of power or even complete engine shutdown in Hitachi wheeled excavators.
1240-1: No pressure supplied to pump (fuel leakage), actual pressure is 50 MPa higher than target.
1239-1: No pressure supplied to pump (fuel leakage), actual pressure is 15 MPa or less than target.
Identifying and addressing fuel leaks quickly is crucial to prevent further damage and ensure safe operation.
