Removing the cartridge group

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.
Do not loosen screw plugs

These screw plugs must not be removed for maintenance work. If a screw
plug is loosened, the gasket can be damaged. This can result in an oil leak.
