The intensity growth of coal consumption at industry in Indonesia gives a positive impact for demand of distributor companies especially used dump truck. The condition of the dump truck is important to be maintained to prevent any traffic accidents while distributes. The component of dump truck frequently get failure along with the loss of truck damage is engine component. A proper maintenance task is important to be determined to prevent any failure in the engine component. Therefore, this paper is aimed to find the proposed maintenance task to eliminate or minimize the engine failure. The method of RCM is applied to define the standard function of engine component. The failure analysis is done by using Fuzzy FMEA to minimize the subjectivity at the assessment. The result of Fuzzy FMEA will be classified by using Pareto chart into three classifications; high, medium and low. Afterwards, the LTA is used to classified the failure based on its consequences; safety, outage and minor economic issues. Finally, the maintenance type is defined in accordance to the classification from Pareto and LTA and the maintenance task is defined. The result shows that there are 17 failures on engine component which classified into 9 failures as a high, 4 failures as a medium and 4 failure as a low. While the maintenance task depends on the type of maintenance; preventive maintenance and predictive testing and inspection.
