What percentage of excavator maintenance cost is the undercarriage?

Expert_Answer

The undercarriage is typically one of the largest maintenance cost areas on an excavator, often accounting for about 20% to 50% of total maintenance costs, depending on machine size, ground conditions, operating habits, and how well the machine is maintained. In severe abrasive applications such as rock, demolition, or sandy ground, that share can be even higher because components like track chains, rollers, idlers, sprockets, and shoes wear faster. Good tension control, regular cleaning, and timely component rotation can help reduce wear and extend service life.
