This box spanner is intended for work on the selector shaft and rocker shaft of the Citroën 2CV. The tool supports assembly and disassembly of parts around the gearbox area. The shape offers access to fasteners that standard tools reach with difficulty. The box section spreads force over the contact surface and limits damage to bolt heads. It is suitable for workshop and garage use. It assists during maintenance, overhaul and repair of the shift system. The construction is matched to the dimensions and position of the related components used in the drivetrain layout of the Citroën 2CV.
