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.

Info
The membrane support plate is curved and must point away from the mem-
brane.
An incorrectly installed membrane support plate results in loss of perfor-
mance and increased oil consumption or leaks.
Do not apply thread locking material between the membrane and the mem-
brane support plate since this would badly affect the functioning.
