This study analyzes the reliability of the Caterpillar 3412 engine used as the main drive for drilling units at PT. XYZ by applying the Reliability Centered Maintenance (RCM) method. The data include operating time, downtime, and maintenance records collected over a six-month period. The analysis stages consist of identifying Maintenance Significant Items (MSI), conducting Failure Mode and Effect Analysis (FMEA), and applying Logic Tree Analysis (LTA). The results indicate that the oil pump, water pump, and radiator are critical components with the highest MSI value of 2.60. Based on FMEA, the oil pump has the highest Risk Priority Number (RPN) of 252, followed by the water pump and radiator. The engine reliability value reaches 0.981, while the Inherent Availability exceeds 90%, indicating high operational readiness. The application of RCM effectively improves engine reliability and operational efficiency.
