8.5 Radial clearances N and R
N and R
These are the theoretical values of the radial clearance between the com-
pressor wheel and the wall insert and / or turbine wheel and the gas out-
let flange.
The minimum and maximum values result from the manufacturing toler-
ances of the compressor wheel and turbine wheel or the wall insert and
gas outlet flange.
Feeler gauge
N1 and N2 as well as R1 and R2 are each
measured at the same time using two
feeler gauges.
To measure N1 and N2, the feeler
gauges must be pushed between the
wall insert and the compressor wheel
free of play, in each case above and be-
low.
To measure R1 and R2, the feeler gauges
must be pushed between the gas outlet
flange and the turbine free of play, in
each case above and below.
