03.05.02 Check bearing clearance
Measure end clearance:
1 Put test prod of dial gauge onto face of turbine wheel
hub.
2 Push cursor downwards and set dial gauge to "0".
3 Pushcursoragainstdialgaugeandnotedeection
of pointer.
permissibleendclearance:max.0.16mm+/-0,01
Measure radial clearance:
NOTE: Determination of radial clearance is
only required turbine-sided.
1 Put test prod of dial gauge onto center of retainer
cone of turbine wheel.
2 Pull turbine wheel hub upwards by means of spring
balance. Measuring strength 50 N.
3 Notedeectionofpointer.
4 Repeat measurement, by turning cursor by 90°.
