• Mining requires some material transfer tools. One of them is Dump Truck. Company X has a Dump Truck that is often damaged. The purpose of this study is to analyze the reliability of Dump Truck108 at mining companies. The method used is Mean Time to Repair (MTTR). MTTR represents the average time of repair of the known data of known repair time. In general, repair time can be applied as a random variable because repetitive events can result in different repair times. The result was 397 hours of improvement on the axle component of The Dump Truck. 86% cause of axle damage due to shaft trunnion left head broke up. Reliability analysis Dump Truck obtained by MTTR value equal to 40, 1095 hours. Design life Dump Truck is 42,9188 hours (90%) and 29,9466 hours (95%). The axle damage reduction solution is by road repairs, reducing the loading capacity of Dump Trucks, performing routine engine maintenance and taking into account the conditions of the Dump Truck driver.
