1. A deflection distributor refitting kit for a roller crusher which comprises a frame and a first crusher roll and a second crusher roll arranged axially in parallel with each other, said first crusher roll being rotatably arranged in and supported by bearing housings which are arranged in the frame, said second crusher roll being rotatably arranged in and supported by movable bearing housings which are arranged to be movable in relation to the frame for varying a gap width between the first and second crushing rolls, and a hydraulic system arranged between the frame and the movable bearing housings and configured to exert a pressure on the movable bearing housings for adjusting the position of the second crusher roll and a crushing pressure between the first and second crusher rolls, wherein the kit comprises:
a deflection distributing shaft;
a pair of thrust rods each having a first end and a second end; and
mounts for rotatable attachment of the deflection distributing shaft at a first and a second side of a frame of the roller crusher, wherein the deflection distributing shaft is rotationally attached to the mounts and the mounts are stationary in relation to the frame, and
a pair of levers each having a first end and a second end, the first end of each of the levers being rigidly attached to one end of the deflection distributing shaft:
wherein the first end of each of the thrust rods is attached to the second end of a respective lever, and wherein the second end of each of the thrust rods is arranged to be attached to a respective one of the movable bearing housing of the roller crusher,
wherein each of the thrust rods and the movable bearing housings of the roller crusher are constrained to move simultaneously on each side of said roller crusher in a substantially linear path.
