V. Applicable Fault Conditions for Replacement

  • Oil seepage or dripping on the outer surface of boom cylinder piston rod
  • Internal cylinder leakage: Automatic boom drop and weak lifting performance
  • Insufficient cylinder pressure and slow boom lifting movement
  • Damaged wiper seal causing sediment intrusion and piston rod scoring

VI. Disassembly & Assembly Instructions

  • Release residual pressure of hydraulic system and fully retract the boom cylinder before disassembly
  • Remove burrs and scratches on cylinder barrel and piston rod surface; polish minor scoring marks
  • Apply factory grease on seals during installation; do not pry seals hard to prevent lip damage
  • Install piston seals and guide bands evenly without twisting or cutting
  • Extend and retract the boom without load for 5–10 cycles to vent air after assembly; confirm zero leakage before operation
