This SBS120 hydraulic piston pump spare parts kit is widely matched for 320C large excavator main hydraulic pump. Complete internal repair components effectively resolve hydraulic pump failure issues and reduce equipment downtime for global machinery repair shops, rental merchants and engineering contractors.
- Insufficient hydraulic output pressure: Worn cylinder block, piston shoe and valve plate cause internal oil leakage, weak digging force
- Pump abnormal vibration & metal knocking noise: Scuffed friction surface generates continuous collision noise
- Pump overhigh oil temperature: Long-hour heavy load friction leads to sustained overheating
- Internal and external oil leakage: Aging sealing parts and damaged sealing surface cause hydraulic oil spill
- Unstable flow output: Uneven component wear leads to fluctuating flow and whole machine jitter
- Travel deviation, unilateral slow walking
- Insufficient climbing torque, machine slips on steep slopes
- Travel motor oil leakage and abnormal running noise
- Weak swing rotation torque, slow slewing
- Swing jitter and friction knocking noise
- Swing shaft oil leakage, swing stuck stall after long operation
- Swing motor overheating under continuous load
- Control spool blocked by hydraulic impurities
- Internal oil leakage, slow boom and bucket action
- Overflow valve pressure abnormality
