This GM38VB travel motor repair kit fully fits medium-load construction 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 drifts during moving forward & backward
• 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 metal jitter & walking noise: Worn gear and bearing create harsh collision sound during moving
• Motor internal overhigh temperature: Long-hour continuous friction leads to rapid temperature rise

• Insufficient hydraulic pressure: Worn cylinder block, piston shoe cause 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 leads to sharp temperature surge
• 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

• Weak swing 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 produces harsh metal noise during left-right rotation
• Swing shaft oil leakage: Damaged rotary oil seal leads to hydraulic oil outflow 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 action reset
• 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 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
