Present study developed and proposed improve steps of Overhaul process which conducted by lean production program. The research procedure includes four stages: analyze the current status, establish improve steps, implement improve step, and confirm improved status after implement improve step. The eight types of waste was confirmed and the improve steps was established after analyze the current status. After implement the improving steps, the Overhaul days was reduced from 88 to 49 days, reduced about 5% of costs, and increased about 18% of profit. The results were confirmed that the Overhaul performance of excavator can be improved by the improving steps which conducted by lean production program.
