A toolkit for mounting a bearing having an inner ring having a tapered bore onto a seating, the toolkit comprising:

• an adapter sleeve configured to be radially interposed between the inner ring and the seating, the adapter sleeve comprising an outer periphery having a tapered portion configured to mate with the tapered bore of the inner ring and a threaded portion configured to extend axially away from the bearing,
• a hydraulic nut having a threaded bore and an axially moveable piston configured to apply an axial force on a side face of the inner ring of the bearing,
• a hydraulic pump configured to increase a hydraulic pressure inside the hydraulic nut,
• a driving tube configured to be interposed axially between the side face of the inner ring of the bearing and the piston, and
• a reaction sleeve configured to be interposed between the hydraulic nut and the adapter sleeve, the reaction sleeve including a first threaded portion configured to engage the threaded portion of the adapter sleeve and a second threaded portion configured to engage the threaded bore of the hydraulic nut.
