How to Assemble Excavator Track Assembly: Detailed Steps and Tips

How to Assemble Excavator Track Assembly
  • Before assembly, check all parts in detail, including whether the track chain has cracks, whether the drive wheel teeth are worn, and whether the guide wheel is flexible.
  • Make sure there is no oil or impurities on the surface of the parts, and clean them with detergent if necessary.
  • When installing the drive wheel, make sure that the bolts are tightened to the specified torque value, and at the same time confirm whether the installation position of the drive wheel and the track frame is correct.
  • When installing the guide wheel, adjust its horizontal position to avoid excessive friction with the track chain.
  • Install the rollers one by one according to the guide rail position of the track frame to ensure that they are stable and without shaking.
  • Rotate the rollers after installation to check whether they can rotate smoothly.
  • Lay the track chain flat on the ground and lift one side of the excavator with a wire rope or hydraulic jack.
  • Starting from the drive wheel, fix one end of the track chain and gradually pass it around the rollers and guide wheels to ensure that the track chain fits tightly with the gear teeth.
  • Use the track pin to connect the two ends of the chain tightly, and use a hammer tool to drive the pin in to ensure that the pin holes are aligned and not loose.
  • When adjusting the tensioner, slowly release the hydraulic oil to achieve a moderate tension of the track.
  • Test the tightness of the track chain to ensure that the vertical droop meets the equipment specifications.

  • During the installation of the track chain, it is necessary to ensure that the tension of the chains on the left and right sides is consistent to prevent deviation or tilt.
  • Apply high-quality lubricating oil to the chain pin connection, drive wheel tooth surface and other easily worn parts.
  • When working in rainy or high humidity environments, use anti-rust spray appropriately.
  • Complete the installation step by step in the order of “drive wheel-roller-guide wheel-chain connection” to avoid improper installation caused by disorder.
  • When the crawler chain is connected, hydraulic auxiliary tools can be used to improve operating efficiency and reduce manual operation errors.

  • In muddy, sandy or high water content environments, foreign objects may get stuck in the crawler chain, causing the risk of derailment.
  • Severe wear of the drive wheel teeth, track bearings or track pins will reduce the stability of the track chain.
  • Misalignment of the track chain or incomplete fixation of the track pins are important causes of derailment.
  • Lack of regular inspection and lubrication maintenance increases the possibility of derailment.

  • Focus on checking the tension of the chain, whether the pin hole is loose, and whether the drive wheel and chain are aligned.
  • If any abnormality is found, it should be repaired in time to avoid failure during construction.
  • After each operation, use a water gun or other tools to clean the soil, sand and other foreign objects in the track.
  • Regularly add lubricating oil to the track chain and each axle every week.
  • Use appropriate protective covers to prevent splashing mud and water from eroding the track.
