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.
Info
When pressing the bearing in, ensure that the engine case section is level to
prevent damage.
Only press the bearings in via the outer ring; otherwise, the bearings will be
damaged when they are pressed in.
–
After the engine case section has cooled, check that the bearings are firmly seated.
Info
If the bearings are not firmly seated after cooling, it is likely that they will
rotate in the engine case when warm. In this case, the engine case must be
renewed.
