In this study, a remanufacturing process technology that includes a bushing assembly process and a polishing process of gear and housing was developed to restore the performance of used oil pump for a 7-speed automatic transmission. The suitability of this remanufacturing process technology for performance restoration was verified by comparing the volumetric efficiency for two remanufactured oil pumps and two original oil pumps. Based on the results over the five definite range of rpm, the volumetric efficiency of the remanufactured oil pumps was more than 95 % compared to the original oil pumps. Therefore, the suitability of the oil pump remanufacturing process technology developed through this study was verified. It was also found that the remanufactured oil pump was restored to a level equivalent to that of the original oil pump. |
