  • the zone 92 of each blocking member 84 extends into the central space 75 in the configuration assembly.
  • the motor bogie 20 being integrated into the motor car 12, a method of dismantling the motor 32 from below the frame 30 is carried out in particular according to the following steps: An operator settles in the lower space 24 under the motor bogie 20 , opposite the central space 75 of the engine 32 concerned; then, by maneuvering from said central space 75, the operator partially unscrews the four fixing rods 80 by actuating the screw heads 82. The operator then positions a lifting table (not shown) under the motor 32, in particular under the body 64 of said motor.

  • the displacement distance along X is in particular greater than or equal to the dimension 63 of the receiving bands 62 described above.
  • the motor 32 is thus released from the vertical stop formed by said receiving 60 and bearing 68 surfaces. Said motor is then lowered into the lower space 24 and possibly moved for maintenance operations. It is then reassembled on the frame 30 by a reverse process.
  • a clear central space 75 opposite the element 35 for fixing the engine 32 to the chassis 30 and the safety device 36, facilitates work on said engine, in particular from underneath the car. motor 12.
