A method for adjusting tension in springs (57) mounted upon rotatable shafts is disclosed. The method comprises the steps of, applying a first and a second wrench (1, 1') for splined engagement with a collar (50) of said shaft so as to hold the collar (50) against movement in an undesired direction. The collar (50) being mechanically connected to at least one spring (57). Furthermore, the step of positioning an axial locking device (7), said axial locking device (7) being provided on at least one of said wrenches (1, 1'), to said collar (50) thereby forming an axial locking engagement of said wrenches (1, 1') to said collar (50) and adjusting tension in said at least one spring (57) by winding said collar (50) with at least one of said wrenches (1, 1') until an appropriate tension of the spring (57) is achieved. It is also disclosed a wrench assembly (1) and a collar system (50) suitable for performing the method. |
