The tracks and undercarriage of the JCB 8018 are subjected to rigorous use and problems in these areas can slow down the mini excavator’s performance. These problems include;

  • Worn out tracks
  • Misaligned undercarriage
  • Dry undercarriage

Troubleshooting Track And Undercarriage Problems

  • Be sure to regularly inspect the tracks for signs of wear and replace them when necessary because if they are damaged it will lead to reduced traction. Also make sure that the tracks are properly tensioned for optimal performance.
  • Carefully inspect the undercarriage components, such as the sprockets and idlers, and realign them if needed.
  • Be sure to grease the undercarriage so as to help prevent premature wear and maintain the mini excavator’s performance.

How To Prevent Problems With The JCB 8018

  • Regularly check and top up the hydraulic fluid, engine oil, coolant and other fluids as recommended in the JCB 8018’s owner’s manual.
  • Replace the air, fuel and hydraulic filters at the recommended intervals to maintain the mini excavator’s performance and prevent debris from entering the system.
  • Apply grease to the various pivot points, bushings and joints to reduce friction and ensure smooth operation.
  • Conduct regular inspections of the excavator’s components, including hoses, belts and seals, and then repair or replace any damaged parts.
  • When the JCB 8018 is not in use, store it in a clean and dry environment, away from extreme temperatures and any corrosive substances like water.

How Often Should I Perform Maintenance On My JCB 8018?

It is recommended to follow the maintenance schedule outlined in the JCB 8018 owner’s manual. Generally regular maintenance tasks such as fluid checks and greasing should be performed on a daily or weekly basis depending on the machine’s usage.

Can I Use Aftermarket Parts For Repairs On My JCB 8018?
