What is the term for the part of a planned maintenance call that involves replacing worn parts and making necessary adjustments?

The term that refers to the part of a planned maintenance call where worn parts are replaced and necessary adjustments are made is routine maintenance. This process is crucial in ensuring that equipment operates efficiently and safely, as it involves proactive care to prevent issues before they arise. Routine maintenance typically encompasses a variety of tasks, including replacing worn components, lubricating moving parts, and recalibrating equipment to ensure it continues to function optimally.

In contrast, routine cleaning focuses on keeping equipment free from dirt and debris, but does not involve any part replacements or adjustments. Routine inspection refers to examining equipment for signs of wear or malfunction without necessarily addressing those issues physically. Routine troubleshooting is about diagnosing and identifying problems after they occur, rather than taking preventive measures. Thus, routine maintenance is the most fitting term for the activities described in the question.
