The low-pressure stage can have an oil inlet either on its right or left side, and this can be
different for the low-pressure stage fitted on the left and right engine bank.
A pin can be installed in the support as an installation safety device to prevent inadvertent
incorrect fitting. This pin fits into the respective slot on the foot of the bearing casing. In-
structions of the enginebuilder must be observed.
