This PSVL-54 hydraulic pump repair kit fully fits all small construction working scenes. Complete swash plate and piston accessories solve pump internal wear faults and lower equipment failure downtime for global mini excavator repair shops, rental companies and small engineering contractors.

• Insufficient system pressure: Worn piston, shoe plate and swash plate lead to internal leakage, whole machine slow and weak digging force
• Abnormal pump noise & vibration: Scuffed swash plate and damaged piston create metal collision noise during pump operation
• Pump overhigh temperature: Severe friction between worn swash plate and piston causes sharp oil temperature rise
• Hydraulic oil leakage: Worn piston seal and pump end cover seal ring result in oil spill from pump housing
• Unstable flow output: Scuffed swash plate surface brings fluctuating pump output and excavator jitter

• Weak swing & sliding slope: Severe wear of motor distribution plate and aging inner seal create high-pressure internal leakage, machine cannot stop steadily on slopes
• Swing jitter & abnormal noise: Broken reducer gear or damaged bearing produces metal friction sound while rotating
• Swing oil leakage: Damaged shaft oil seal leads to hydraulic oil spill from swing motor housing
• Swing stuck & overheat: Long continuous slewing operation causes whole hydraulic system overheat

• Travel deviation: Inconsistent displacement of two-side travel motors, servo valve failure or central swivel joint seal oil leakage
• Single side no travel: Broken travel reducer gear or stuck parking brake cannot release normally
• Weak climbing travel: Stuck motor displacement adjustment mechanism, low speed with insufficient slope climbing torque

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

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

This PSVL-54 swash plate and piston accessory kit repairs insufficient pump pressure, abnormal pump noise, pump overheat, hydraulic oil leakage and unstable flow output caused by internal pump wear.
