When mounting new bearing components, observe the enclosed instruction manual and, where applicable, the
instructions and values provided by the respective manufacturer!
CAUTION!
As the types of the FAG and the “standard”
torque wrench differ, the correct torque values
as mentioned in Step 1 of the bearing fitting
must be used!
It is not permitted to interchange the processes.
For the FAG tool the centre of the locknut and
the torque of the release mechanism are not
identical.
This results in different leverages, and
therefore, settings, for both torque wrenches
