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.
