Common Questions About Excavator and Mining Equipment Parts
What are the common signs of a failing hydraulic pump in an excavator?
Common signs include slow or weak hydraulic functions, unusual noises (whining or grinding), overheating of hydraulic fluid, and milky or foamy hydraulic fluid.
How often should I replace the travel final drive oil in my mining equipment?
The replacement interval varies depending on the manufacturer and operating conditions. Consult your equipment's manual, but generally, it's recommended every 1000-2000 hours or annually.

Engine Troubleshooting Tip
Problem:
Engine overheating with steam coming from the radiator.
Possible Causes and Solutions:
- Low Coolant Level: Check the coolant level in the radiator and expansion tank. Add the recommended coolant mixture if low.
- Leaking Radiator Hose: Inspect all radiator hoses for leaks or damage. Replace any damaged hoses and tighten clamps.
- Faulty Thermostat: A stuck closed thermostat can prevent coolant circulation. Replace the thermostat with a new one of the correct temperature rating.
- Clogged Radiator: Over time, the radiator can become clogged with debris or scale. Flush the radiator or have it professionally cleaned.
- Water Pump Failure: If the water pump is not circulating coolant effectively, the engine can overheat. Inspect the water pump for leaks or bearing noise. Replace if necessary.
- Head Gasket Leak: In severe cases, overheating can be caused by a blown head gasket allowing combustion gases into the cooling system. This often requires professional repair.
