NOTICE
Do not remove oil orifice (if present)
To limit the oil flow rate through the bearing casing during operation (engine under load) to the
admissible values, an oil orifice is mandatory at the oil inlet of the bearing casing if the oil inlet
pressure is > 3 bar (overpressure).
If an oil orifice is fitted in the oil inlet of the bearing casing, it must not be removed.
