Described is a method for assembling a gyratory crusher (1) where a main shaft arrangement (2) having a main shaft (3) with a midmost axial portion enclosed by a first crushing surface (4) is lowered axially from a free-hanging position down into a centrally positioned bushing (5) which provides guidance and support for the main shaft (3) where at least a portion of the bushing (5) is located below the first crushing surface (4) which is configured for interaction with an opposite second crushing surface (6). The method is characterized in that the method comprises the steps of mounting guiding means (7) on the main shaft arrangement (2) prior to guiding the main shaft (3) into the bushing (5) where the guiding means (7) protrude radially in relation to the centre axis of the main shaft (3) to such an extent that the guiding means (7) are visible when viewed from an axial top position over the main shaft arrangement (2), and having an operator with a view from the axial top position to lower the main shaft (3) down into the bushing (5) while observing the relationship between the second wear surface (6) and the guiding means (7).
