Initial Setup: Parking and Lifting the Excavator

Before you begin removing the used excavator tracks, you need to properly position and lift your mini excavator. This step ensures stability and safety throughout the replacement process. Follow these instructions carefully to prepare your machine for the task.

Positioning the Excavator

  Park the excavator on a flat, level surface

Choose a stable and even surface to park your excavator. Uneven ground can cause the machine to shift or tip, increasing the risk of accidents. A flat surface provides the stability needed for safe lifting and track replacement.

  Lower the boom and bucket to stabilize the machine

Lower the boom and bucket until they rest firmly on the ground. This action helps anchor the excavator and prevents unnecessary movement. The added stability will make lifting the machine safer and more efficient.

   Pro Tip: Double-check that the parking brake is engaged before proceeding. This small step adds an extra layer of security.

Lifting the Excavator

  Use the boom and blade to lift the excavator rubber tracks off the ground

Activate the boom and blade to lift the excavator slightly off the ground. Raise the machine just enough to ensure the tracks are no longer in contact with the surface. Avoid lifting it too high, as this could compromise stability.

  Secure the machine with a jack or lifting equipment before proceeding

Once the excavator is lifted, place a jack or other lifting equipment under the machine to hold it securely in place. Ensure the jack is positioned correctly to support the weight of the excavator. This step prevents the machine from shifting or falling while you work on the tracks.

  Safety Reminder: Never rely solely on the boom and blade to keep the excavator lifted. Always use proper lifting equipment to secure the machine.

By carefully positioning and lifting your excavator, you create a safe and stable environment for replacing the tracks. Proper setup reduces risks and ensures the process goes smoothly.

Removing the Old Track

Removing the Old Track

Removing the old track from your excavator with rubber tracks requires precision and the right approach. Follow these steps to ensure a smooth and efficient process.

Loosening Track Tension

  Locate the grease fitting on the track tensioner (typically 21mm)

Begin by identifying the grease fitting on the track tensioner. This fitting is usually 21mm in size and is located near the undercarriage of the excavator. It plays a crucial role in adjusting the track tension. Take a moment to inspect the area and confirm its position before proceeding.

  Remove the grease fitting to release grease and loosen the track

Use the appropriate wrench or socket to remove the grease fitting. Once removed, grease will start to release from the tensioner. This action reduces the tension in the track, making it easier to remove. Allow enough grease to escape until the track becomes loose. Be cautious during this step to avoid any sudden release of pressure.

    Pro Tip: Keep a container or rag handy to collect the grease and prevent it from spilling onto the ground. Proper cleanup ensures a safer and more organized workspace.

Detaching the Track

  Dislodge one end of the track using a pry bar

With the track tension loosened, use a sturdy pry bar to dislodge one end of the track. Start at the sprocket end, as this is typically the easiest point to access. Apply steady pressure to lift the track off the sprocket teeth. Work carefully to avoid damaging the sprocket or the track itself.

  Slide the track off the sprockets and rollers, then set it aside

Once one end of the track is free, begin sliding it off the sprockets and rollers. Use your hands or the pry bar to guide the track as it comes off. Move slowly and methodically to prevent the track from getting stuck or causing injury. After removing the track completely, place it in a safe location away from your workspace.

    Safety Reminder: Tracks can be heavy and cumbersome to handle. If needed, ask for assistance or use lifting     equipment to avoid strain or injury.

By following these steps, you can successfully remove the old track from your rubber tracks for mini excavator. Proper technique and attention to detail will make the process more manageable and prepare you for installing the new track.
