This GM38VB travel motor repair kit fully fits medium-load construction working scenes. Complete internal drive accessories solve walking system failure problems and greatly reduce equipment downtime for global excavator repair shops, machinery rental companies and 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
