Hey there! I’m a supplier of used excavators, and I know that buying a used excavator can be a bit of a minefield. You want to make sure you’re getting a machine that’s in good condition and will serve you well for years to come. So, in this blog post, I’m gonna share with you some tips on how to check the condition of a used excavator. Used Excavator
1. Visual Inspection
The first thing you gotta do is give the excavator a good visual once – over. Start from the outside and work your way in.
- Exterior Body: Look for any signs of dents, scratches, or rust. Dents can indicate that the machine has been in an accident, and rust is a sign of poor maintenance. Check the paint job too. If it looks uneven or has been recently touched up, it could be hiding some damage.
- Tracks and Undercarriage: The tracks are a crucial part of the excavator. Check the track links for wear and tear. Look for any missing or damaged track pins. The undercarriage should be free of excessive dirt and debris. Check the rollers and idlers for smooth rotation. If they’re making a grinding noise or are hard to turn, it could mean they need to be replaced.
- Cab and Controls: Step into the cab and take a look around. Check the seats for wear, and make sure all the controls are in working order. The gauges should be clear and easy to read. Look for any signs of water damage, like a musty smell or water stains. The windows should be intact, and the door should open and close smoothly.
2. Engine Check
The engine is the heart of the excavator, so it’s important to check it thoroughly.
- Oil and Fluid Levels: Check the engine oil, coolant, hydraulic fluid, and fuel levels. The oil should be clean and not have a milky appearance, which could indicate water contamination. The coolant should be at the proper level and not have any signs of rust or sediment. The hydraulic fluid should be clear and free of debris.
- Engine Compartment: Open the engine compartment and look for any signs of leaks. Check the hoses and belts for cracks or wear. The air filter should be clean. A dirty air filter can reduce engine performance and cause premature wear.
- Engine Start – Up: Start the engine and listen to it. It should start smoothly without any knocking or rattling noises. Pay attention to the exhaust smoke. If it’s black, it could mean the engine is burning too much fuel. Blue smoke indicates oil burning, and white smoke could be a sign of a head gasket leak.
3. Hydraulic System
The hydraulic system is what makes the excavator’s arms and attachments work, so it’s essential to check it.
- Hydraulic Hoses: Inspect the hydraulic hoses for any signs of leaks, bulges, or cuts. A leaking hose can cause a loss of hydraulic pressure and affect the machine’s performance.
- Hydraulic Cylinders: Check the hydraulic cylinders for leaks. Look at the rod seals for any signs of oil seepage. The cylinders should extend and retract smoothly without any jerks or sticking.
- Hydraulic Performance: Operate the excavator’s arms, boom, and bucket to test the hydraulic performance. The movements should be smooth and responsive. If there’s any hesitation or slow movement, it could be a sign of a hydraulic problem.
4. Attachment Inspection
If the used excavator comes with attachments like buckets, thumbs, or breakers, you need to check them too.
- Bucket: Inspect the bucket for wear. Check the teeth for damage or excessive wear. The bucket should be firmly attached to the excavator’s arm, and the pins and bushings should be in good condition.
- Other Attachments: For other attachments like breakers, check the hoses and connections for leaks. Make sure the attachment is in working order by testing it if possible.
5. Operational Testing
Now it’s time to take the excavator for a spin and see how it performs in real – world conditions.
- Drive and Maneuverability: Drive the excavator around the yard or test area. It should move smoothly forward and backward. Check the steering to make sure it’s responsive. The brakes should work effectively.
- Lifting and Digging: Use the excavator to lift and move some objects or do some light digging. The machine should be able to handle the load without any issues. Pay attention to how it performs under different operating conditions.
6. Maintenance Records
Ask the seller for the excavator’s maintenance records. A well – maintained machine is more likely to be in good condition. The records should show when the oil changes, filter replacements, and other maintenance tasks were performed. If there are no maintenance records, it could be a red flag.
7. Get a Professional Inspection
If you’re not confident in your ability to check the excavator’s condition, it’s a good idea to hire a professional mechanic or equipment inspector. They have the expertise and tools to detect any hidden problems that you might miss.
Conclusion
Checking the condition of a used excavator takes time and attention to detail, but it’s worth it to ensure you’re making a good investment. By following these tips, you can increase your chances of buying a used excavator that will meet your needs and perform well for a long time.
