3. Orient the motor conduit box in the required
position. Align the motor mounting holes with the
mating tapped holes on the discharge head. Lower
the motor until the registers engage and the motor
rests on the discharge head. Secure motor with
capscrews provided.
4. On drivers having a non-reverse ratchet or pins,
manually turn the driver shaft clockwise viewed
from the top until the non-reverse ratchet or pins
fully engage.
5. Lubricate motor bearings in accordance with
instructions given on lubrication plate attached to
the motor case.
NOTE: Please read and follow the motor manufacturer’s
instructions before lubricating the motor
bearings. Too much lubricant can cause the
bearings to overheat and prematurely fail.
The motor must not be tested for direction
of rotation when coupled to the pump.
If pump should rotate in the wrong direction, serious
damage to the pump and motor would result. Also
serious injury to personnel could result.
6. Make temporary electrical connections according
to tagged leads or diagram attached to the motor.
Motor must rotate counter-clockwise when viewed
from the top. See arrow on pump name plate. If
motor does not rotate counter-clockwise, you can
change the rotation by interchanging any two leads
(For three phase only, for single phase motors see
motor manufacturer’s instructions.)
7. Motor shaft end play adjustment: if required,
motor shaft end play shall be checked with a dial
indicator prior to connecting the pump coupling to
the solid shaft motor. Consult the applicable motor
manufacturer’s instruction manual for detailed
information on motor shaft end play.
COUPLING INSTALLATION: (SEE FIGURES 14 and 15)
1. Check all mating face with a fine flat file before
installation. Remove all burrs from face.
2. Apply a thin film of oil on the pump key (730) and
insert key into headshaft keyway seat.
3. Gently lower pump hub of coupling (614) onto
headshaft.
4. Thread on the adjusting plate (613) onto the
headshaft until flush with top of the headshaft.
5. Clean driver shaft by removing all grease and burrs.
Try to fit the key on the driver hub (610) before
installing it to the driver shaft.

6. Apply a thin film of oil to the driver key (730) and
insert key into drive shaft keyway seat. Place the
driver hub (610) onto the drive shaft and with key
slide it up the drive shaft until the annular grove is
exposed. Install split ring (722) in the groove and
slide driver hub down over the split ring to capture it.
7. If the pump is supplied with an adjustable spacer
coupling (see Figure 15), install spacer (612) between
headshaft and driveshaft hubs. Secure with capscrews
(759) and hex nuts (735).
