1. A system for disengaging a drive shaft from a bearing support, the system comprising:
a support device provided to carry the bearing support in which the drive shaft is engaged;
a cylinder mechanically coupled to the support device, the cylinder configured to be placed under the drive shaft and to push the drive shaft upwards;
a first force transfer device disposed around the drive shaft above the bearing support, the first force transfer device configured to block the bearing support so as to prevent the bearing support from displacing upward;
a second force transfer device mechanically coupled to the support device, the second force transfer device configured to prevent the bearing support from displacing upwards, the second force transfer device being disposed around the first force transfer device to block the first force transfer device so as to prevent the first force transfer device from displacing upwards; and
wherein the second force transfer device comprises a first portion and a second portion configured to move horizontally away from and towards each other so as to assemble together, each of the first and second portions comprising a hole portion, such that when the first and second portions are assembled together, the hole portions together form an upper hole adapted to be passed through by the drive shaft.
