Excavator top rollers are also part of the track tensioning system. Your excavator track tension is crucial, as it dictates how long your excavator track serves you. Improper track tensioning causes premature wear on your excavator track system.

They also allow dirt and debris to get out of your excavator chain, meaning that your chain will not have any buildup.

4.  What Are the Internal Components of An Excavator Top Roller?

Your excavator track top roller has internal components that help it function properly. Check them out:

Your excavator top roller has an outer shell that protects the inner components from physical damage. It is made from high-quality casted alloy steel that is resistant to contaminants. The roller also has a floating oil seal that prevents lubricant leakage.

If so, you’ll need to acquire heavy-duty top rollers for your excavator. They’ll be able to serve you for long, as well as make your excavator more productive by reducing excavator downtime.

7.  How Can I Recognize the Wear Patterns of Excavator Top Rollers?

9.  What Causes Wear on Excavator Top Rollers?

As you continually use your excavator, the top rollers are bound to wear out over time. However, top rollers require you to maintain them properly for them to last longer.

In other words:

The main reason why your excavator top rollers wear out is due to improper maintenance of your excavator undercarriage. For example, when you’ve completed using your excavator, it would be best if you’d clean your excavator undercarriage using a pressure washer.

Washing your excavator undercarriage will help you get rid of contaminants that corrode the surface of your undercarriage components. It also removes the buildup that causes your excavator top rollers to get stuck.

10. How Can I Know If My Excavator Top Rollers Have Ceased Working?

Excavator top rollers cease working when they are completely worn out or when they are stuck due to excessive amounts of buildups.

Here’s how you can tell if your excavator top rollers have ceased working:

• You’ll find old dirt on their surfaces. Old dirt signifies that the rollers are no longer rolling as they are completely damaged or simply stuck due to buildup.
• You’ll also find oil leakage, which is usually a sign that shows you that you need to replace your excavator top rollers, as they are no longer working.

11. Why Do My Excavator Top Rollers Leak Oil?

The most probable reason why your excavator top rollers leak oil is that their internal seals are damaged. Whenever you find leaked oil on the surface of your excavator track chain or on the surface of the top roller itself, consider replacing the roller after establishing that its seal is damaged.

The second reason why your excavator top rollers may leak oil is when they work under extremely hot environmental conditions. Heat makes oil less viscous, meaning it can easily pass the seals, even though the seals are in good condition.
