- Weak swing rotation & slow slewing: Worn distribution plate, piston and sealing parts lead to insufficient swing torque, slow left-right rotation
- Swing jitter & abnormal metal collision noise: Damaged reducer gear, bearing wear create harsh vibration noise during slewing
- Swing shaft oil leakage: Aging shaft seal ring leads to continuous hydraulic oil spill from motor housing
- Swing stuck stall: Long continuous swing operation causes internal overheating and clamping stagnation, unable to rotate freely
- Motor internal overhigh temperature: Long-hour heavy load friction and oil leakage trigger rapid temperature rise
- Swing sliding on slope: Internal seal failure causes high-pressure oil leakage, machine cannot lock position on inclined ground
- Insufficient hydraulic output pressure: Worn cylinder block, piston shoe and swash plate cause internal oil leakage, whole machine slow & weak digging force
- Abnormal metal noise & pump vibration during running: Scuffed friction surface generates continuous collision noise
- Pump overhigh oil temperature: Long-time internal friction leads to sharp temperature surge
- Pump housing oil leakage: Aging piston seal and end cover seal ring result in sustained oil spill
- Unstable oil flow output: Worn friction surface causes fluctuating oil supply and whole excavator jitter while digging
- Travel deviation, unilateral slow walking: Inconsistent left-right displacement caused by worn piston and valve plate, excavator drifts during moving
- Single side no walking output: Broken reduction gear, stuck parking brake cannot release, one track completely immobile
- Poor ramp climbing performance: Insufficient driving torque from worn internal friction parts, machine slides backward on steep slopes
- Final drive oil leakage: Aging shaft seal leads to hydraulic oil outflow from walking motor shell
- Walking metal noise & vibration: Worn gear and bearing produce harsh collision sound during forward & backward travel
- Spool stuck: Hydraulic oil impurities block spool gap, heavy operation handle, slow boom & bucket action reset
- Internal & external oil leakage: Worn gap between spool and valve body leads to oil leakage, mutual interference of each digging action
- Overflow valve pressure failure: Stuck relief valve causes system zero pressure or pipeline burst due to overpressure
- Insufficient power & black exhaust smoke: Blocked air filter, aging fuel injector lead to incomplete combustion
- Excessive water & engine oil temperature: Radiator silt blockage, deteriorated engine oil trigger high temperature alarm
- Difficult cold startup: Starter failure, battery aging or air entering fuel pipeline
