This GM09VA travel motor repair kit fully fits all small construction working scenes. Complete internal drive accessories solve walking system failure problems, greatly reduce equipment downtime for global mini excavator repair shops, rental firms and small engineering contractors.

• Travel deviation, one side slow walking: Worn piston, valve plate and seal lead to inconsistent left-right displacement, machine always drifts during moving
• Single side no travel output: 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 and housing seal ring lead to continuous hydraulic oil spill from motor housing
• Travel motor abnormal noise & vibration: Worm gear and bearing wear create harsh metal noise during forward & backward travel

• 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 & vibration during pump operation: Scuffed cylinder block surface and damaged piston generate collision noise
• Pump housing overhigh oil temperature: Severe friction between worn cylinder block and piston leads to sharp oil temperature surge
• Hydraulic oil leakage outside pump body: Worn piston sealing ring and pump end cover seal ring result in continuous oil spill
• Unstable flow output: Scuffed cylinder block friction surface causes fluctuating pump output and whole excavator jitter during work

• Weak swing rotation & easy sliding on slopes: Severe wear of motor distribution plate and aging inner seal create high-pressure internal leakage, machine cannot stop stably on inclined ground
• Swing jitter & abnormal friction noise: Broken reducer gear or damaged bearing produces harsh metal friction sound while rotating left and right
• Swing shaft oil leakage: Damaged rotary shaft oil seal leads to hydraulic oil spill from swing motor housing
• Swing stuck & sudden stall: Long continuous slewing operation causes motor internal overheat and clamping stagnation

• Spool clamping stagnation: Hydraulic oil impurity blocks spool clearance, heavy operation handle, poor reset & insensitive boom/arm/bucket action
• Internal & external oil leakage: Worn gap between valve spool and valve body causes inner oil leak; aging seal rings lead to cross-action interference of boom and bucket
• Overflow valve pressure failure: Stuck main relief valve or insufficient spring pressure, system no pressure or overpressure burst hydraulic pipe

• Power drop & black exhaust smoke: Clogged air filter leads to insufficient air intake, poor atomization of fuel injector and high-pressure oil pump
• Overhigh water & engine oil temperature: Radiator blocked by silt, deteriorated engine oil or stuck thermostat
• Difficult cold startup: Starter breakdown, dead battery or air entering fuel pipeline
