Aspects of the disclosure relate to methods, apparatus, and systems for replacing a drive assembly. A system includes a bogie assembly comprising a wheel and a drive assembly configured to drive the wheel to roll on a top surface of a structure. The system further includes a translating cartridge movably mounted to a side surface of the structure. The translating cartridge pivots from a first orientation to a second orientation to couple with the drive assembly and decouple the drive assembly coupled to the translating cartridge from the bogie assembly.
