resting on the point of the motor shaft support tool (see
Fig. 13).
Make sure the tolerance ring (Ref. 2) is positioned in
the undercut on the shaft (see Fig. 14). Set the rotor
down onto the shaft. Be sure the rotor end with thread-
ed holes and tightening disk pocket is at the top. Use a
soft hammer to tap the rotor down until there is approx-
imately 1/4” clearance between the rotor and endplate.
To set the axial clearance, insert a feeler gauge (see
Clearance Chart in Fig. 18) between the rotor face and
the motor side endplate (see Fig. 15). Insert the secur-
ing disk (Ref. 8) into the pocket in the center of the face
of the rotor. Place the M6 hex head cap screw (Ref. 9)
and lockwasher (Ref. 10) into the center hole on the
tightening disk.
Tighten the cap screw until the feeler gauge can be
pulled out but has a slight amount of resistance.
6.2 Cylinder
Lift the pump off the motor shaft support tool and repo-
sition it on its base plate (Ref. 48). Slide the cylinder
onto the rotor and loosely assemble it to the endplate
with two M6 socket head cap screws (Ref. 15). Insert a
feeler gauge (see Fig.18 for thickness) between the top
of the rotor and the bore of the cylinder. Move the cylin-
der up and down until the feeler gauge can be pulled
between the rotor and cylinder with a slight resistance.
When the correct radial clearance is achieved, tighten
the cap screws, locking the cylinder in place (see Fig.
16).
6.3 Motor Cover, Plastic
Slide the plastic cover (Ref. 40) over the motor end of
the pump until it is in its original position. Roll the pump
over on its side exposing the bottom of the base plate.
Screw the four socket head cap screws (Ref. 50) into

CAUTION: The use of the motor shaft tool
prevents side load damage to the motor
bearings when the rotor is tapped into posi-
tion.
