An overhaul is a major maintenance event that goes far beyond routine servicing. It involves stripping a piece of equipment down to its bare components, measuring parts for wear against factory tolerances, replacing seals and bearings, and reassembling the unit. It is scheduled based on operating hours to prevent catastrophic failure in heavy machinery like turbines and diesel engines.
