Fig. 42: Optional spanner holder
ABB offers an optional spanner holder (90165) (see Dismantling and fitting, special tools for
fastening strips →150) which, in the event of limited accessibility, can be used to facilitate
the loosening of nuts and the application of tightening torques for the strip connection
between the cartridge group and the turbine casing.
The spanner holder (90165) should only be used for loosening the nuts and applying tighten-
ing torques for the nuts at the position shown.
Other screws or nuts on the turbocharger should not be tightened with this tool.
