Equipment for disassembling a planet carrier is provided. The planet carrier includes a cage, a cage carrier, and a connection shaft. The cage includes an inner bridge and an outer bridge. The cage carrier include a finger bar to be inserted between the inner bridge and the outer bridge. The connection shaft is housed in through-holes formed in the bridges and in the finger bar, such as to retain the cage on the cage carrier. The equipment includes a jack and a support. The jack includes a body and a piston, the piston being designed to apply a force to the connection shaft. The support is designed to bear on the finger bar when the piston applies a force to the connection shaft.

A wheel for distributing a lubricant in a turbine engine has an axis from which an annular cavity extends, open radially towards the axis and from which first and second lubricant supply lines depart for various members to be lubricated. Parallel to the axis, the annular cavity is split into at least a first and a second annular sub-cavity, which are separated by a substantially radial partition and which communicate with the first and second lines respectively.

The invention concerns a device () for hoop reinforcing of restrictors inside at least two hydraulic supply standby systems of a journal bearing. Said device is remarkable in that it comprises: a frame () for receiving said hearing, a syringe () for introducing said restrictors and a torque pick-off spindle (), and in that said frame () comprises: a cradle (), a guide plate () pierced with two guide openings (), inclined at the same angle as those of said backup systems of the bearing, so as to be located in the extension of same when the bearing is in the frame, said guide openings () being shaped to receive said syringe () or said torque pick-off spindle ().
