How to Maintain the Undercarriage of an Excavator

Keeping your excavator in top shape is crucial for maintaining its performance and extending its lifespan. The undercarriage of an excavator often endures the most wear and tear, as it supports the machine's weight and navigates challenging terrains. Regular maintenance can prevent costly repairs and ensure that your equipment remains efficient. Here, we outline essential steps to maintain your excavator's undercarriage.

Regular Cleaning: Your First Defense Against Wear

Dirt, mud, rocks, and debris can accumulate quickly on the undercarriage, leading to accelerated wear. Make it a routine to clean these components after every use. Use a pressure washer to remove stubborn dirt and debris from tracks, rollers, and idlers. Regular cleaning not only prevents corrosion but also enables you to inspect for other issues more easily.

Check Track Tension for Optimal Performance

Proper track tension is crucial for smooth operation. If tracks are too tight, they cause excessive strain on other parts; if too loose, they increase the risk of derailment. To check track tension, lift the machine slightly off the ground using its boom and arm. Measure track sag between idlers or rollers—adjust according to your manufacturer’s guidelines if needed.

Inspect and Lubricate Moving Parts 

Regularly inspect all moving parts like rollers, sprockets, and idlers for signs of wear or damage. Proper lubrication is necessary to reduce friction that leads to wear over time. Following a consistent lubrication schedule enhances component performance and extends their life.

Monitor Wear Components Proactively

Inspecting wear components like track shoes or chains should be part of your regular maintenance routine. Pay close attention to bushings and links as well—they often need replacement before other elements do. Being proactive in monitoring these components helps avoid unexpected downtime.
