2. Five Core Machinery Module Common Faults & Matching Repair Solutions

2.1 Hydraulic Main Pump Exclusive Faults (HPV35 Specialized Core Search Fault Words)

• Insufficient hydraulic output pressure: Worn cylinder block, piston shoe and swash plate cause internal oil leakage, whole machine slow digging & weak power
• Abnormal metal collision noise & pump vibration during operation: Scuffed friction surface generates harsh continuous collision noise
• Pump overhigh oil temperature: Long-time continuous friction of worn internal parts leads to rapid temperature surge
• Main pump body oil leakage: Aging piston seal and end cover seal ring lead to continuous hydraulic oil spill
• Unstable oil flow output: Worn friction surface causes fluctuating oil supply and whole excavator jitter while digging

2.2 Travel Final Drive Motor Common Faults

• Travel deviation, unilateral slow walking: Worn piston and valve plate lead to inconsistent left-right displacement, machine drifts during moving
• Single side no travel output power: Damaged reduction gear, stuck parking brake cannot release normally, one track completely immobile
• Weak climbing ability on ramp: Worn internal friction parts cause insufficient torque, machine slides backward on slopes
• Final drive oil leakage: Aging shaft seal leads to hydraulic oil outflow from walking motor housing
• Abnormal walking metal noise: Worn gear and bearing produce harsh collision sound during forward & backward travel

2.3 Swing Rotary Motor Common Faults

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

2.4 Multi-way Distributing Control Valve Faults

• 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

2.5 Diesel Engine Matching Faults

• Insufficient power & black exhaust smoke: Blocked air filter, aging fuel injector lead to incomplete combustion
• Excessive water temperature & 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
