Insert the new cold bearings in the bearing seats of the
heated section of the engine case; if necessary, use a
suitable press drift to push them all the way in and make
them flush.

When pressing the bearing in, ensure that the engine
case section is level to prevent damage.
Only press the bearings in via the outer bearing race;
otherwise, the bearings will be damaged when they
are pressed in.
