Common Excavator Undercarriage Problems And How To Fix Them

Excavators are essential pieces of equipment in the construction industry, used for digging, lifting, and moving materials. However, like any heavy machinery, excavators can experience undercarriage problems that can hinder their performance and efficiency. In this article, we will discuss some common excavator undercarriage problems and provide solutions on how to fix them.

1. Track Tension Issues

One of the most common undercarriage problems with excavators is track tension issues. If the tracks are too loose or too tight, it can cause premature wear and tear on the undercarriage components. To fix this problem, you will need to adjust the track tension according to the manufacturer's specifications. This can usually be done by adjusting the track tensioner located on the side of the undercarriage.

2. Worn Out Track Shoes

Another common problem with excavator undercarriages is worn-out track shoes. Over time, the track shoes can become worn down due to constant use on rough terrain. To fix this issue, you will need to replace the worn-out track shoes with new ones. It is important to regularly inspect the track shoes for signs of wear and replace them as needed to prevent further damage to the undercarriage.

3. Sprocket and Idler Damage

The sprockets and idlers on an excavator's undercarriage are responsible for driving the tracks and keeping them in place. If these components become damaged or worn out, it can cause the tracks to slip or come off completely. To fix this problem, you will need to inspect the sprockets and idlers for any signs of damage and replace them if necessary. Regular maintenance and lubrication of these components can help prevent premature wear and extend their lifespan.

4. Track Chain Stretch

Track chain stretch is another common undercarriage problem that can occur on excavators. This is often caused by improper track tension or lack of lubrication on the track chain. To fix this issue, you will need to adjust the track tension and ensure that the track chain is properly lubricated. If the track chain is severely stretched, it may need to be replaced to prevent further damage to the undercarriage.
