2.12.3 Fitting n and v indicators
Fig. 2-42 Fitting indicators / pressing on v indicator
Procedure
Push the auxiliary bezel on.
The n and v measuring systems are in their initial positions.
Close the housing cover.
Push the n indicator (2) on.
The indicator's tip must point to the 2nd zero of the "x100/min" dial labelling.
Push the v indicator (1) on by hand so that it points to about 20 km/h and turn
it into the direction of the arrow until the speed shaft (4) engages into the cou-
pling.
Then turn the v indicator back until the indicator is about 1 mm away from the
indicator stop pin (3).
Now press the v indicator on.
When doing this, open the housing cover and support the speed shaft (4).
2.12.4 Checking indicator running
Check With RPM units the distance between the v indicator and the n indi-
cator should be 0.3 mm.
With speed units the distance between the v indicator and dial should
be 0.3 mm.
When the housing cover is closed, the v indicator may move away
from the indicator stop pin by about one indicator width*.
Correct this if necessary, i.e. remove the v indicator and fit it again.
