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 deflection 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 deflection of pointer.
4
Repeat measurement, by turning cursor by 90°.
Permissible radial clearance: max. 0.42 mm +/-0,04
