Following removal and before installation of the cartridge group, the
axial clearance A and radial clearance B must be measured and
noted.
NOTICE
In order to correctly measure the axial clearance A, the turbine must be
raised slightly.
WARNING
Risk of injury due to sharp edges on the compressor wheel
The compressor wheel has sharp edges which can cause injuries.
Wear safety gloves.
Wear safety gloves against mechanical risks.

* Permissible B clearances for standard radial bearings. If the clearances
measured on TPS57 or TPS61 are outside the permissible range, this can
indicate radial bearings with a special bearing geometry. Different
permissible values are valid for radial bearings with a special bearing
geometry (see the table below).
