Abstract

Remanufacturing is a process of reusing used parts with almost the same quality as new products. The 6D114 series engine components have the problem of a low contribution margin due to high production costs cause by small reuse ratio of the used parts. The piston part has a replacement ratio of 100%. This study aims to reduce production costs by increasing reusable parts, especially piston parts. Reusable criteria parameters for pistons are obtained from the reverse engineering. Then the process of remaining life assessment is carried out by looking at the effect of the wear level on the ring groove 1 and 2 pistons, a performance test is performed, specifically the compression pressure test and blow-by pressure test. And to validate the simulation results and performance tests, a seeding test is carried out on the unit. From the results of this study, it is found that the parameters for determining the reusable part of the piston are the worn-out value of the piston ring groove, compression pressure, and blow-by pressure. From the reusable piston results, it can reduce the cost of purchasing piston parts by 98.8%. This resulted in an increase in the contribution margin from 7.8% to 12.6%.
