To check the speed drop of an excavator, start by testing the engine’s output power. If it’s lower than the rated power, inspect components like air valves, fuel injectors, the turbocharger, and the hydraulic pump. Common issues include poor fuel quality, low fuel pressure, incorrect valve clearance, and turbocharger carbonization. If the engine’s output power is normal, ensure the hydraulic pump’s flow rate matches the engine’s output. Speed issues may also stem from the pump control system, requiring checks of the electrical, hydraulic, and mechanical transmission systems.

Regular maintenance and inspection of various filters and the cooling system are crucial for ensuring equipment operates smoothly and extends its lifespan.

Hydraulic oil leaks in excavators can cause weak digging and slow operation. Look for oil stains or dust on the cylinder rod, which may indicate a leak or bad seal. Ignoring leaks can contaminate the hydraulic system and lead to expensive repairs. Fix leaks quickly and replace seal kits if needed. When replacing, use the correct part number, carefully disconnect hoses, and check all parts. If unsure, get professional help. Common leak causes include worn seals, damaged rods, and wrong hydraulic fluid.
