This SBS80 piston pump spare parts set includes E312C swash plate saddle and E315D drive shaft, widely matched for excavator main hydraulic pump. Standard replacement components resolve common pump failures and reduce equipment downtime for global repair shops, machinery rental merchants and engineering contractors.

• Insufficient hydraulic output pressure: Worn swash plate and drive shaft lead to internal oil leakage, weak digging force
• Pump abnormal vibration & noise: Scuffed friction parts create continuous shaking
• Pump overhigh oil temperature: Long-hour load operation leads to sustained overheating
• Internal and external oil leakage: Aging matching surfaces cause hydraulic oil spill
• Unstable flow output leads to whole machine jitter

• Travel deviation, unilateral slow moving
• Insufficient climbing torque, machine slips on 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
• Swing motor overheating after long continuous operation

• Control spool blocked by hydraulic impurities
• Valve body internal leakage, slow boom & bucket action response
• Overflow valve pressure abnormality
