2. Typical Hydraulic Pump Faults & Repair Solutions
2.1 K3SP36B Hydraulic Pump Common Failures
- Insufficient hydraulic output power: Internal wear leads to weak digging force
- Pump abnormal vibration & noise: Worn friction components cause continuous shaking
- Pump overhigh oil temperature: Long-hour load operation leads to sustained overheating
- Internal and external oil leakage: Aging sealing parts cause hydraulic oil spill
- Unstable flow output leads to whole machine jitter
2.2 Travel Motor Common Faults
- Travel deviation, unilateral slow moving
- Insufficient climbing torque, machine slips on slopes
- Travel motor oil leakage and abnormal running noise
2.3 Swing Rotary Motor Common Faults
- Weak swing rotation torque, slow slewing
- Swing jitter and friction knocking noise
- Swing shaft oil leakage, swing stuck stall
- Swing motor overheating after long continuous operation
2.4 Multi-way Control Valve Faults
- Control spool blocked by hydraulic impurities
- Valve body internal leakage, slow boom and bucket action
- Overflow valve pressure abnormality
