One of the most crucial inspection tips for used backhoes is to understand which parts of the machine to check before making a purchase. You have to make sure everything is running well and that you won't end up having to pay for extra repair work after buying the backhoe. By conducting an in-depth inspection of a used backhoe loader, you can ensure you're getting a backhoe in good condition.
Review the things to check before buying a used backhoe below:
1. Hydraulic System
A backhoe's hydraulic system is crucial for the machine's moving parts. A damaged system can cause these parts not to work entirely or operate at a less efficient pace. To ensure the backhoe works efficiently, you need to inspect the various hydraulic parts.
Begin by looking at the hoses, searching for any scratches or breaks while also ensuring the couplings are in prime condition. After checking couplings and hoses, look for cylinders that are leaking or damaged, as dents or scratches are indicators something could be wrong. Damage like dents and scratches can also open your hydraulic system to contaminants.
2. Engine
After checking the hydraulic system, inspect the engine, which should be located close by. Check for loose belts, out-of-date filters and obvious leaks. You can check a filter's status by looking at the last service date on the machine's notes.
3. Loader Bucket, Bucket Cutting Edge and Bucket Teeth
A backhoe's loader bucket is an essential piece of the machine. Make sure it's in good condition by observing the bucket and looking for signs of damage. As you search for wear, examine the bucket side panels' thickness, the bottom's condition, the structural integrity of bucket welds and the state of the leading edges.
You should also see if the bucket teeth have any missing bolts or missing, worn or loose teeth. Next, inspect the bucket's cutting edge for signs of damage, such as scalloping. If you notice that the bucket's cutting edge is worn down, you can often flip it to keep it working.
4. Loader Arms
Once you've checked the bucket, you should also inspect the loader arms the bucket attaches to. Examine the arms for bends, re-welds and cracks. If you notice re-welds, you'll know that some repair work has been done. This should be a sign you need to review the workmanship and see if it was done by a professional. Bends will indicate that the machine was likely rolled, and cracks are often a sign of the backhoe loader being pushed beyond its capacity.
5. Cab
To make sure your operator will have acceptable conditions while driving the backhoe loader, examine the cab. Look over the foot pedals, joysticks and seat. Next, check for any additional pieces of technology or features. While in the cab, look for an hour meter reading to see if the wear is appropriate for how long the backhoe has been used.
You should also be given a chance to operate the backhoe loader to see if it runs well. Start the machine and put it through some standard operating tasks. After starting the backhoe, use the attachments and drive the backhoe, paying close attention. If you notice that it's hard to steer, the operating attachments lose pressure, there's a chattering noise or a high fluid temperature, it's likely the hydraulic system is damaged.
6. Tires and Axles
You can usually find loader backhoes with three kinds of axle configurations: 4x2, 4x4 or 4x4x4. Verify the equipment's configuration by inspecting the tire size and checking if the front axle has a drive shaft and differential. You can also verify the axle configuration with the machine's manufacturer. As you examine the axles, look for any signs of leakage.
