Top 7 Common Excavator Hydraulic Pump Problems and How to Fix Them Excavators are built for heavy-duty work, and at the heart of their performance lies the hydraulic pump. When this pump starts to fail, even a minor issue can slow down operations or cause complete machine downtime. Operators who understand the usual problems can often spot trouble early and avoid expensive repairs. Here are seven common issues you’ll come across: 1. Low Pressure – Usually linked to leakage inside the pump or seals that have worn out. 2. Overheating – A filter that is dirty or the incorrect type of oil are often reasons the pump is running hotter than normal. 3. Strange Noises – Air bubbles, cavitation, or parts that have come out of alignment can cause whining, rattling, or vibrations. 4. Sluggish Response – When the machine feels sluggish, it may be due to low oil or a blocked hydraulic line. 5. Oil Leaks – Typically, a crack in a hose, a weak fitting, or bad seal, account for leaking oil. 6. Worn Parts – Running on old oil or contaminated oil can cause the wear on pump parts to happen faster. 7. Sudden Failure – If the machine is neglected for too long, it could totally fail and simply stop working.
