If there are no markings or they are worn, it is easiest to check the impeller type as fol-
lows:
1. Push the impeller in the cone as deep as it goes.
2. Place a straight ruler against
the rear edge of the cone as in-
dicated in figure 3.4-3 and me
-
asure the distance from the rear
edge of the cone to the rear edge
of the impeller.
This measure is about 2 mm at
the smallest.

3. The impeller blade span is
measured as indicated in figure
