Didn’t do excavator maintenance? Have you ever had to stop on a job suddenly because your machine isn’t running? Have you ever had to call for an emergency mechanic to come out and fix your broken machine? Have you ever faced having to pay the repairman extra to come out on the weekend or a holiday? By the way, do you know what the definition of a holiday is when you are an independent contractor? It’s “I have work to do, so the holiday doesn’t matter.” Because when your machine breaks, you’ve got to get back to work..
You’re going to start having a performance issue. It may even lead to early part failures. You’re definitely going to impact the life of that machine. While, in the short term, it may save you a little time and money to skip a few service checks, the reality is the long-term cost of skipping those checks far outweighs the short-term savings you may have gotten.
Now, the best thing to do is to establish a service and maintenance routine on your machine. This will boost its performance, extend its life and, in the end, make you much happier as you operate it, saving you a lot of time, a lot of money, and a lot of headache when that machine does break. Whether you’re doing preventative service checks or corrective maintenance to fix something that’s fallen apart, doing regular service is the most effective technique for getting the best performance out of that money-sucking, earth-moving machine.
1. Ensures Optimal Engine Performance
Excavators are heavy-duty machines that endure a lot of stress and wear during their operations. From digging trenches to lifting heavy loads, these machines are constantly working under pressure. Regular maintenance ensures that each component—from the engine to the hydraulic system—is performing at its peak, reducing the chances of a breakdown and improving the efficiency of operations.
By maintaining your excavator properly, you not only protect its parts but also enhance its fuel efficiency, improve lifting and digging performance, and reduce the likelihood of unexpected repairs. Regular maintenance helps keep the excavator running smoothly, preventing small issues from turning into costly repairs down the road.
How Regular Excavator Maintenance Helps:
- Prevents Overheating: Clean oil and air filters help maintain proper engine temperature, preventing overheating, which can lead to engine failure.
- Improves Fuel Efficiency: A well-maintained engine uses fuel more efficiently, lowering fuel costs and reducing the frequency of refueling.

7. Key Maintenance Tasks to Perform Regularly
Regular maintenance is crucial for ensuring your excavator runs smoothly and efficiently throughout its life. Neglecting routine checks and repairs can lead to expensive breakdowns and a significant drop in performance. Below are key maintenance tasks you should always perform:
7.1 Regularly Check Fluid Levels
Excavators rely heavily on hydraulic fluid, engine oil, and coolant to function effectively. Low fluid levels can cause parts to overheat, increase friction, and ultimately lead to system failures. Here’s what you need to check:
- Hydraulic fluid: Ensure that the hydraulic fluid is at the optimal level, as it is crucial for the excavator’s lifting and digging performance.
- Engine oil: Inspect the engine oil regularly to prevent the engine from overheating or seizing up. If the oil appears dirty, it may be time for a change.
- Coolant: Check the coolant level to avoid engine overheating. The engine should always run at a consistent temperature, and low coolant can lead to thermal damage.
7.2 Inspect the Tracks or Tires
The undercarriage of an excavator takes a lot of wear and tear, particularly if you operate on rough terrain. Regularly inspecting the tracks or tires can prevent costly damage.
- Tracks: Ensure the tracks are aligned and free from debris. Misaligned tracks can cause uneven wear and potential damage to the undercarriage system.
- Tires: For wheeled excavators, inspect the tires for wear and tear, and check for proper air pressure. Worn tires reduce stability and increase fuel consumption.
7.3 Clean the Excavator Regularly
Dirt and debris can accumulate in hard-to-reach areas, leading to blockages and reduced efficiency. Make sure to clean both the exterior and the undercarriage of the excavator to prevent these issues.
- Exterior cleaning: Wash the excavator regularly to remove dirt, mud, and debris that could clog air vents, radiator fins, or other cooling components.
- Undercarriage cleaning: Use a pressure washer or other cleaning tools to keep the undercarriage clear of dirt. A clean undercarriage not only improves the longevity of the machine but also helps in tracking down early signs of wear.
7.4 Lubricate Moving Parts
Moving parts, such as the arm, bucket, and joints, are subjected to significant stress during operation. Regular lubrication is vital to ensure smooth movement and reduce wear.
- Grease: Apply grease to the arm, boom, and other key components. Lubricating the moving parts reduces friction, minimizes wear, and enhances digging and lifting capabilities.
- Joint lubrication: Pay close attention to the joints where the boom connects to the excavator body, as they often experience the most strain.
7.5 Monitor Hydraulic Systems
The hydraulic system is the heart of the excavator, powering key movements like lifting, digging, and tilting. Regularly checking for leaks and maintaining the hydraulic fluid can prevent major hydraulic system failures.
- Hydraulic hoses and pipes: Inspect hoses for signs of wear, cracks, or leaks. If any hoses appear damaged, replace them immediately to prevent system failure.
- Hydraulic fluid filters: Replace hydraulic filters as per the manufacturer’s recommendations. Clogged filters reduce hydraulic fluid flow and can lead to overheating and system failure.
7.6 Check the Engine and Battery
The engine and battery are vital for the proper functioning of your excavator. Regular inspection and maintenance will keep your machine running smoothly.
- Engine air filters: Clean or replace the air filter regularly to ensure the engine receives a constant flow of clean air, preventing clogging and overheating.
- Battery: Check the battery charge levels regularly, and clean the battery terminals to prevent corrosion and ensure smooth operation.
8. Scheduling Maintenance: Time and Cost Savings
While it may seem like regular maintenance is an added cost, in the long run, it saves you money by avoiding expensive repairs and replacements. By sticking to a scheduled maintenance routine, you can also increase the resale value of your excavator, as a well-maintained machine is always more appealing to potential buyers.
8.1 Setting Up a Maintenance Schedule
A good maintenance schedule includes daily, weekly, and monthly tasks. Here’s a breakdown of what should be done:
- Daily: Check fluid levels, inspect for leaks, and clean the machine.
- Weekly: Inspect the undercarriage, lubricate moving parts, and check the hydraulic system.
- Monthly: Clean air filters, check battery condition, and inspect the engine for performance.
8.2 Regular Professional Inspections
While some tasks can be done in-house, it’s also essential to have your excavator inspected by a professional mechanic every 6-12 months. Professional inspections help catch hidden issues before they become significant problems. They may also suggest improvements to your maintenance routine, improving both efficiency and lifespan.
To ensure your excavator remains in top condition, setting up a regular maintenance schedule is essential. Below is an example of what a schedule might look like:
| Task | Frequency | Purpose |
| Check and top-up fluid levels | Daily or before use | Ensures proper fluid levels for optimal operation |
| Clean undercarriage | Weekly | Prevents dirt buildup and potential damage |
| Inspect hydraulic hoses | Weekly | Prevents leaks and ensures smooth hydraulic operation |
| Replace engine air filter | Monthly | Improves air flow to the engine and enhances efficiency |
| Inspect and lubricate tracks | Monthly | Prevents wear and tear on tracks and undercarriage |
| Professional inspection | Every 6-12 months | Identifies hidden issues that require expert attention |
This schedule should be tailored to your excavator’s usage, the working environment, and manufacturer guidelines. Staying consistent with these tasks helps ensure that all components remain in peak condition.
