In the previous document, we explained and analyzed in detail the steps of replacing the rubber track of mini excavator. We can go back to the first part through this link and recall the detailed operation steps and detailed preparations again. Next, we will discuss the subsequent adjustments and precautions.

Final Adjustments: Re-Tensioning and Testing

After installing the new track, you must make final adjustments to ensure proper functionality. This step involves re-tensioning the track and testing its performance. Follow these instructions to complete the process effectively.

Adjusting Track Tension

Refer to the manufacturer’s specifications for proper tension

Check the manufacturer’s guidelines to determine the correct tension for your mini excavator rubber tracks. These specifications ensure the track operates efficiently without unnecessary strain on the machine. Keep the manual or reference material nearby for quick access during this step.

Use a grease gun to add grease and tighten the track

Take your grease gun and connect it to the grease fitting on the track tensioner. Slowly pump grease into the fitting while observing the track’s tension. Stop periodically to check if the track has reached the recommended tension level. Avoid over-tightening, as this can damage the track and other components. Proper tension ensures the track stays secure during operation.

Pro Tip: Measure the sag in the track between the rollers to confirm it matches the manufacturer’s specifications. This method provides an accurate way to verify tension.

Testing the Installation

Lower the excavator and remove the jack

Carefully lower the excavator back to the ground by releasing the lifting equipment. Ensure the machine rests evenly on the surface. Once lowered, remove the jack or any other lifting tools used during the process. Double-check that the excavator is stable before proceeding.

Test the tracks by moving the excavator forward and backward

Start the engine and disengage the parking brake. Move the excavator forward a few feet, then reverse it. Observe how the tracks perform during this movement. Pay attention to any unusual noises or irregularities, as these could indicate improper installation or tension.

Inspect the tracks for proper alignment and tension

After testing, stop the machine and inspect the excavator rubber tracks closely. Look for signs of misalignment or uneven tension. Ensure the track sits correctly on the sprockets and rollers. If adjustments are needed, use the grease gun to fine-tune the tension. A properly aligned and tensioned track will improve the performance and longevity of your excavator with rubber tracks.

Safety Reminder: Always turn off the engine and engage the parking brake before inspecting the tracks. This precaution prevents accidental movement during the inspection.

By completing these final adjustments, you ensure the new track is secure and ready for use. Proper re-tensioning and testing not only enhance the machine’s performance but also reduce the risk of future issues. Take your time during this step to confirm everything is in order before returning to work.

Replacing the excavator tracks on your excavator with rubber tracks becomes manageable when you follow clear, step-by-step instructions. By using the right tools and prioritizing safety, you can complete the task efficiently and without unnecessary risks. Proper installation ensures your machine operates smoothly, while regular maintenance extends the lifespan of the tracks. With this guide, you gain the confidence to handle track replacement and keep your equipment in excellent working condition. Take the time to follow these steps, and you’ll be back to work in no time.

FAQ

How often should you replace rubber tracks on a mini excavator?

The lifespan of rubber tracks depends on usage and maintenance. On average, you should replace them every 1,200 to 1,600 hours of operation. However, frequent use on rough terrain or poor maintenance can shorten their lifespan. Regularly inspect the tracks for wear and damage to determine when replacement is necessary.

What are the signs that rubber tracks need replacement?

Look for visible cracks, tears, or missing chunks in the rubber. Check for exposed steel cords or excessive stretching. If the tracks frequently slip off the rollers or sprockets, it may indicate they are worn out. Reduced traction and uneven wear patterns also signal the need for replacement.

Can you replace rubber tracks without professional help?

Yes, you can replace rubber excavator tracks yourself if you have the right tools and follow proper safety measures. This guide provides step-by-step instructions to help you complete the task efficiently. However, if you feel unsure or lack the necessary equipment, consider hiring a professional.

How do you ensure the new tracks are properly aligned?

To ensure proper alignment, position the new track over the sprocket first and then guide it under the machine. Align it carefully with the rollers and sprockets. After installation, test the alignment by moving the excavator forward and backward. Inspect the track for any misalignment and make adjustments if needed.

What happens if the track tension is too tight or too loose?

Excessive tension can strain the track and other components, leading to premature wear or damage. Loose tension can cause the track to slip off during operation. Always refer to the manufacturer’s specifications for the correct tension and adjust it using a grease gun.

Do you need special tools to replace rubber tracks?

Yes, certain tools are essential for replacing rubber tracks. These include wrenches, a socket set (typically 21mm for the grease fitting), a pry bar, a grease gun, and lifting equipment like a jack. Having these tools ensures a smoother and safer replacement process.

How can you prevent premature wear on rubber tracks?

To extend the life of your mini digger tracks, avoid operating the excavator on sharp or abrasive surfaces. Regularly clean the tracks to remove debris and inspect them for damage. Maintain proper track tension and follow the manufacturer’s guidelines for usage and care.

Is it necessary to lift the excavator to replace the tracks?

Yes, lifting the excavator is necessary to remove and install the tracks. Use the boom and blade to raise the machine slightly off the ground. Secure it with a jack or lifting equipment to ensure stability and safety during the replacement process.

Can you reuse old rubber tracks?

Reusing old rubber tracks is not recommended if they show significant wear or damage. Worn-out tracks can compromise the performance and safety of your excavator. If the tracks are still in good condition, you may keep them as spares, but always prioritize safety and efficiency.

How do you dispose of old rubber tracks?

Contact a local recycling center or waste management facility to dispose of old rubber tracks. Many facilities accept rubber tracks for recycling, which helps reduce environmental impact. Avoid discarding them in regular trash, as they are not biodegradable.
