1. A tool for mounting a bearing and shaft subassembly in an aircraft engine component, the bearing and shaft subassembly having a hollowed shaft extending from a first end to a second end along a shaft axis, and at least one bearing mounted on the hollowed shaft, the tool comprising:
a rod extending from a first rod end to a second rod end, the rod adapted to extend through the hollowed shaft, the rod having a shaft seating portion at the first rod end, the shaft seating portion adapted to engage the first end of the hollowed shaft;
a holder engageable to the second rod end, the holder adapted to receive the second end of the hollowed shaft, the holder displaceable towards the shaft seating portion during engagement to the second rod end; and
at least one sleeve adapted to wrap about an outer surface of the hollowed shaft, the at least one sleeve removably securable to the hollowed shaft, the at least one sleeve having an end defining a bearing facing surface to axially engage the at least one bearing, and the holder being displaceable towards the bearing facing surface during engagement of the holder to the second rod end to axially load the at least one bearing against the at least one sleeve and maintain the hollowed shaft between the holder and the shaft seating portion;
wherein the rod has a first part and a second part axially engaged to the first part, the first and second parts concentric one with respect to the other, the first part being a tubular part, the second part extending through the first part, a biasing member between the first part and the second part, the first part axially retractable relative to the second part, in a retracted state, the first part uncovering a periphery of the second end of the rod on the second part, the biasing member biasing the first part in a biased state in which the periphery of the second rod end of the rod on the second part is covered by the first part.
