Hey there! As a supplier of used diggers, I know how crucial it is to ensure the steering system of these machines is in top - notch condition. A well - functioning steering system not only guarantees the safety of the operator but also significantly impacts the efficiency of the digging operations. In this blog, I'll share some practical tips on how to check the steering system of a used digger.
First things first, let's talk about the visual inspection. This is the most basic yet important step. When you're looking at a used digger, start by checking the steering wheel. Look for any signs of excessive wear, like a loose grip or a wobbly feel. A worn - out steering wheel can make it difficult to control the digger accurately. You should also check the steering column. Look for cracks, dents, or any signs of damage. If there are visible issues with the column, it could be a sign of more serious problems within the steering system.
Next, take a close look at the steering hoses. These hoses are responsible for carrying hydraulic fluid, which is essential for the proper functioning of the steering system. Check for any leaks, bulges, or abrasions on the hoses. A small leak might seem insignificant at first, but it can lead to a loss of hydraulic pressure over time, causing the steering to become stiff or unresponsive. If you notice any of these issues, it's a red flag that the hoses may need to be replaced.
Now, let's move on to the steering pump. The steering pump is like the heart of the steering system, as it provides the hydraulic power needed to turn the wheels. Start the digger and listen carefully. A healthy steering pump should operate quietly. If you hear any strange noises, like whining or grinding, it could indicate a problem with the pump. Maybe there's a blockage in the pump, or the internal components are worn out. In such cases, it's best to have a professional mechanic take a closer look.
Another important component to check is the steering cylinder. The steering cylinder is what actually moves the wheels when you turn the steering wheel. Extend and retract the steering cylinder a few times while the digger is in a safe and stationary position. Observe the movement carefully. It should be smooth and consistent. If you feel any jerks or resistance, it could mean that there's an issue with the cylinder. There might be air in the hydraulic system, or the seals in the cylinder could be damaged.


After the physical inspection, it's time to test the steering in action. Take the digger for a short test drive in a safe area. Start by making slow, gentle turns. Pay attention to how the steering responds. It should be easy to turn the wheel, and the digger should follow the direction you're steering. If you have to use excessive force to turn the wheel, it's a sign that there's a problem with the steering system. You can also try making some sharp turns at a low speed. This will put more stress on the steering system and help you detect any potential issues that might not be apparent during normal driving.
When you're testing the steering, also check for any play in the steering. Play refers to the amount of movement the steering wheel can make before the wheels start to turn. A small amount of play is normal, but if there's excessive play, it can make the digger difficult to control. You might notice that the steering wheel can be turned a few degrees without the wheels moving, which is a clear indication of a problem.
