It involves removing 32 components in 31 steps, including removing the final drive cover, gears, carrier assemblies, planetary gear assemblies, and ring gear. Special tools are required to remove components and many components are heavy, requiring two people or lifting devices to remove safely due to weights from 32 kg to 550 kg. Cleanliness is important during disassembly to prevent dirt from entering internal mechanisms.
