• Travel deviation, one side slow walking: Worn piston, valve plate and oil seal cause inconsistent left-right displacement, excavator drifts during moving forward & backward
• Single side no walking output: Damaged reduction gear, stuck parking brake cannot release normally, one track completely immobile
• Weak climbing ability on ramp: Internal friction parts wear leads to insufficient driving torque, machine slides backward on steep slopes
• Final drive oil leakage: Aging shaft seal and housing sealing ring lead to continuous hydraulic oil spill from motor housing
• Travel motor abnormal metal jitter & walking noise: Worn worm gear and bearing produce harsh collision sound during moving
• Motor internal overhigh temperature: Long-hour friction and oil leakage trigger rapid temperature rise during continuous construction

• 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 operation: Scuffed friction surface creates metal 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 continuous oil spill
• Unstable oil flow output: Worn friction surface causes fluctuating oil supply and whole machine jitter

• Weak swing rotation & easy sliding on slopes: Internal distribution plate wear and aging seal lead to high-pressure oil leakage, unable to stay stable on inclined ground
• Swing jitter & abnormal friction noise: Broken reducer bearing and gear produce harsh metal noise during left-right rotation
• Swing shaft oil leakage: Damaged rotary oil seal causes hydraulic oil outflow from swing motor shell
• Swing stuck stall: Long continuous rotation leads to internal overheating and clamping stagnation

• 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 no 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
