5.2.4 Adjusting the pump rotor
The rotor is not set on pumps that are fitted
with an electric motor ex-works.
Only drive CVP pumps with electric motors
that have a fixed bearing that cannot be shifted
from the B side to the A side.
Setting the rotor requires a fitting lever, a
marking tool, a power drill, a screwdriver and a
hexagonal socket wrench.
1. Press the pump rotor down together
with the coupling shells until the impel-
lers are in axial contact with the wear
plate. Mark the pump shaft.
2. Raise the pump rotor with the coupling
shells by the "y" dimension (
à
Figure
7, pg 19) and mark the pump shaft.
3. Evenly tighten the socket head cap
screws (29 and 30) (
à
Figure 6, pg 18
and Figure 7, pg 19).
4. Check the pump rotor setting.
5. Drill a hole in the motor shaft and se-
cure the coupling shells against axial
shift with a grub screw (31).
