• Insufficient hydraulic pressure: Worn cylinder block, piston shoe lead to internal oil leakage, slow digging and weak power
• Abnormal pump metal noise & vibration: Scuffed friction surface creates collision noise during operation
• Excessive pump oil temperature: Long-time friction of worn parts causes rapid temperature rise
• Pump housing oil leakage: Aging piston seal and end cover seal lead to continuous oil spill
• Unstable oil flow: Worn friction surface leads to fluctuating output and whole machine jitter

• Travel deviation, unilateral slow walking: Worn piston and valve plate cause inconsistent left-right displacement, machine drifts during moving
• Single side no walking power: Damaged reduction gear or stuck parking brake leads to one track immobile
• Poor ramp climbing capacity: Internal friction wear causes insufficient torque, easy backward sliding on slopes
• Final drive oil leakage: Aging shaft seal leads to hydraulic oil outflow from motor housing
• Abnormal walking metal noise: Worn gear and bearing produce harsh collision sound

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

• Spool stuck: Oil impurities block spool gap, heavy operation handle, slow boom & bucket reset action
• Internal & external oil leakage: Spool and valve body wear gap leads to oil leakage, mutual interference of each digging action
• Relief valve pressure failure: Stuck relief valve causes system no pressure or pipeline burst due to overpressure

• Insufficient power & black 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
