Hitachi Landy 120-2 Engine Loading Issue
#1
Engine Performance Problem
A user described an issue with their Hitachi Landy 120-2 excavator, where the engine struggles or bogs down when under load. The machine starts and idles fine but loses power when digging or lifting heavier materials.
Possible Causes
Members suggested several possible reasons for the engine loading problem. Common culprits included fuel system blockages, clogged filters, or a failing fuel pump. Some pointed out that air leaks in the fuel lines or low fuel pressure could also cause power loss.
Hydraulic System Influence
Several responses highlighted that hydraulic system problems can overload the engine. For example, sticking control valves or relief valves set too high can put extra demand on the engine, making it work harder than it should.
Inspection and Maintenance Tips
Advice included checking and replacing fuel filters, inspecting fuel lines for leaks or cracks, and testing fuel pressure to ensure proper delivery. Cleaning or replacing air filters was also recommended to avoid airflow restrictions.
Further Diagnostics
Some users recommended observing engine exhaust for black smoke, which could indicate overfueling, or white smoke, which might suggest other engine problems. Others advised verifying that the turbocharger, if equipped, is working correctly.
Conclusion
Solving the Hitachi Landy 120-2 engine loading issue requires checking the fuel system, air intake, and hydraulic components that might be overloading the engine. Careful inspection and systematic maintenance are the keys to restoring proper power and performance.
