Changing the rubber tracks on an excavator It may seem daunting, but with the right tools and guidance, it’s manageable even for operators with basic mechanical skills. Rubber tracks wear out over time, and replacing them is essential to maintaining performance, safety, and efficiency.
Rubber tracks wear out due to prolonged use on rough terrain. Signs that it’s time to replace them include:
Visible cracks, splits, or tears.
Reduced traction.
Frequent slippage during operation.
Signs of internal damage, such as stretched tracks or exposed cords.
Before you begin, gather the necessary tools:
Jack or track lift.
Wrenches or a socket set.
Pry bar or crowbar.
Grease gun.
Lubricant spray.
Safety gloves and goggles.
Ensure Safety: Park the excavator on a flat surface, turn off the engine, and apply the parking brake.
Lift the Excavator: Use a jack or track lift to slightly raise the machine, allowing the track to hang freely.
Locate the grease fitting on the track adjuster.
Use a grease gun to relieve pressure by loosening the valve and allowing grease to escape.
Push the idler wheel inward to fold up the track system.
Start by loosening the track bolts and carefully prying the track off the sprockets using a pry bar.
Slide the track out from the rollers, taking care to do so carefully to avoid damaging the undercarriage.
Align the new rubber track with the sprocket teeth.
Place the track on top of the sprocket and gradually fit it around the rollers and the idler.
Make sure the track is centered.
Use a grease gun to pump grease back into the tensioner to extend the idler and tighten the track.
Adjust until the track is at the correct tension, as specified in the manufacturer’s guidelines.
Lower the excavator and check the track alignment.
Test the movement by operating the excavator slowly to ensure smooth operation.
Always wear appropriate safety gear.
Never work under a suspended excavator without proper supports.
Follow the manufacturer's instructions for adjusting the tension.
Depending on usage and terrain conditions, rubber tracks generally last between 1,200 and 2,000 operating hours.
Yes, with the right tools and guidance, operators can replace rubber tracks. However, professional assistance is recommended for larger excavators.
Delaying replacement can lead to reduced performance, increased wear on other components, and safety hazards.
Refer to your excavator's manual or check the markings on the current tracks for specifications.
Replacing the rubber tracks on an excavator is essential for maintaining operational efficiency and safety. While the process may seem challenging, following this guide ensures it goes smoothly. Regularly inspecting and replacing tracks not only improves performance but also extends the service life of your machine.
