A power pack (1) comprising a support (2), a drivetrain subassembly (13) and an electric motor (19). The support (2) comprises: a torque tube (3), wherein the torque tube (3) extends between at least a first location (5) and a distal second location (11); a torque mount (7) at the first location (5) of the torque tube (3), wherein the torque mount (7) is configured to mount to a chassis (103) of a prime mover (101); and a torque transfer plate (9) at the second location (11) of the torque tube (3). A housing (15) of the drivetrain subassembly (13) is located inside the torque tube (3) and mounted (16) to the torque transfer plate (9), and wherein an output drive shaft (17) of the drivetrain subassembly (13) passes through the torque mount (7). The electric motor (19) is mounted (20) to the support (2) and is mechanically coupled (21) to drive the drivetrain subassembly (13). Torque (23) at the housing (15) of the drivetrain subassembly (13) is transferred to the chassis (103) via the torque transfer plate (9), the torque tube (3), and the torque mount (7).
