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 allowing to vary a gap width between the first and second crushing roll, 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 two crusher rolls, wherein the kit comprises, wherein the kit comprises:
a deflection distributing shaft,
a pair of thrust rods each having a first and a second end,
mounts for rotatable attachment of said deflection distributing shaft at a first and a second side of a frame of said 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 said thrust rods is attached to the second end of a respective lever, wherein the second end of each of said thrust rods is arranged to be attached to a respective one of said movable bearing housings of said roller crusher, and wherein the deflection distributing shaft comprises at least two interconnectable sub-shafts.
