I. Immediately Stop the Machine and Allow it to Cool Naturally
Let it idle for 5-10 minutes before shutting it off to prevent damage to the turbocharger and oil circuits due to thermal shock.
Wait at least 30 minutes for it to cool naturally, ensuring the coolant temperature is <85°C and the hydraulic oil temperature is <60°C. Forced cooling or adding cold water is strictly prohibited.
II. Replace Core Fluids to Restore System Performance
Replace the engine oil and filter: Overload causes high-temperature oxidation of the engine oil, resulting in loss of lubrication protection; it must be completely replaced.
Replace the hydraulic oil and filter element: This prevents deteriorated fluids from causing valve sticking and pump wear, ensuring system stability.
Check the transmission fluid condition: If it is a traction impact roller, ensure the gear oil is not deteriorated and top it up to the standard level.
III. Quickly Inspect High-Risk Components
Vibration Bearing: Use a stethoscope to check for any abnormal "humming" or "clicking" noises; replace it immediately if any abnormality is found.
Steel Wheel Welds: Focus on inspecting the hub connections and reinforcing rib areas for signs of cracks.
Hydraulic System: Observe if the hydraulic fluid is blackened, has a burnt smell, or contains metal shavings; check for leaks at pipe joints.
IV. Cleaning and Reset, Preparing for Low-Load Testing: Clean the radiator, engine compartment, and steel wheels of any adhering substances (such as asphalt or mud) to ensure efficient heat dissipation.
Reset instrument parameters, clear ECU fault codes, and confirm that the EMS system has resumed normal monitoring.
During the initial run, perform a low-load test for 10–15 minutes, observing for any abnormal noises, leaks, or abnormal temperature rises.
