How to Fit Rubber Tracks on an Excavator: A Step-by-Step Guide
Replacing the rubber tracks on your excavator is an essential part of regular equipment maintenance. Correct installation ensures optimal machine performance, reduces the risk of undercarriage damage, and helps maintain operator safety. In this guide, we outline the key steps involved in fitting rubber tracks on most compact and mid-sized excavators.
Step 1: Prepare the Work Area and Equipment
Start by choosing a level, stable surface to work on. Shut off the engine before beginning any maintenance work. Ensure the machine is secure and supported using proper lifting equipment such as a jack, excavator boom support, or sturdy cribbing blocks.
Safety Reminder: Always wear proper personal protective equipment (PPE), including gloves, steel-toed boots, and eye protection.
Step 2: Release Track Tension
Locate the grease fitting on the track tensioner (usually near the front idler). Carefully loosen the fitting to release pressure and allow the front idler to retract. This will slacken the track, making it easier to remove.
Have a container or rags ready, as grease will discharge once the fitting is opened.
Step 3: Remove the Old Track
With tension released, use a pry bar to begin sliding the rubber track off the sprocket at the rear of the undercarriage. Slowly rotate the track (by hand or by gently operating the controls if necessary) to work it free from the idler and rollers. Rubber tracks are heavy—lifting equipment or a second person may be needed.
Step 4: Inspect and Clean the Undercarriage
Before installing the new track, take time to inspect the undercarriage:
Check sprockets, idlers, and rollers for signs of wear or damage.
Clean debris and buildup from all components to ensure smooth operation.
Verify alignment and note any issues that could affect track performance.
Replacing worn parts at this stage can prevent future problems and prolong the life of your new tracks.
Step 5: Install the New Track
Position the new rubber track around the rear sprocket first. Begin working it forward toward the idler. As you rotate the track, guide it into place over the rollers and front idler. Use a pry bar or assistance as needed to help position the track without forcing or stretching it excessively.
Ensure the track pattern is facing the correct direction, especially if the tracks are directional (look for V-pattern treads).
Step 6: Re-Tension the Track
Once the track is correctly seated, re-tighten the grease fitting and use a grease gun to re-pressurize the tensioner. Add grease gradually to extend the idler until the track achieves proper tension.
Track Tension Tip: Most manufacturers recommend a slight sag—typically about 1 to 2 inches of vertical slack (depending on the size of machine) between the bottom roller and the track when lightly pressed. Always refer to your excavator’s manual for the specific tension specification.
Step 7: Lower the Machine and Test
Once tension is set, carefully remove any lifting equipment or supports and lower the excavator to the ground. Start the machine and gently operate the controls to move the tracks forward and backward a few times.
Observe for any unusual movement or noise. Make sure the track runs smoothly over the sprockets and rollers.
Final Tips:
Re-check tension after several hours of use. New tracks can settle, especially during initial use.
Perform regular maintenance on undercarriage components to extend the life of your tracks.
Always follow your machine’s specific service manual for any brand-specific procedures or tension settings.
