Keep Your Excavator Swing Motor in Peak Condition with These Pro Maintenance Tips

If your excavator swing motor fails, your entire machine can come to a halt. That’s why keeping it in top condition is essential. Many contractors overlook swing motor maintenance until there’s a serious breakdown. But with the right care, you can extend its lifespan, reduce downtime, and get better performance out of your machine every day. At Global Hydraulic System, we know what it takes to keep your equipment running smoothly—and we’re here to help.

Start by checking the hydraulic oil. Clean, high-quality oil is the lifeblood of your swing motor. Dirty or degraded oil can cause internal damage fast. Inspect the oil regularly and change it based on usage hours or if contamination is suspected. Also, make sure the oil you use matches the specifications for your equipment. Using the wrong fluid can shorten your motor’s life.

Next, inspect the seals and hoses. Leaking seals or cracked hoses reduce pressure and can let in contaminants like dust and water. Even small leaks should never be ignored. If you notice oil around the motor housing, take action immediately. A timely replacement of seals can save you from more expensive repairs later.

Cleanliness is another key factor. Keep the swing motor and surrounding area clean. Dust, dirt, and debris buildup can lead to overheating and premature wear. If you're operating in harsh environments like mining or construction, consider cleaning the motor after each shift.

Listen to your machine. Unusual noises—grinding, knocking, or whining—are signs of internal wear or misalignment. These shouldn’t be dismissed as “normal wear.” Early detection can prevent total failure.

Don’t forget the swing bearing. This part works closely with the swing motor and should be greased according to the manufacturer’s recommendation. Too little or too much grease can both lead to issues. Make it a routine part of your inspection process.
