Table 6-7. Mounting and Installing the Motor Plates and Coupling for Electric Direct-Coupled Drive System
Step Action
1 Attach the motor to the motor plate with the bolts, lock washers, and nuts
provided with the Contherm
™
package. Each motor is provided with four
bolts, flat washers, lock washers, and hex nuts.
The Contherm
™
Motor Plate Assembly is shown in Figure 6-8. The
location of the motor plate on the vertical mount is preset by Alfa Laval Inc.
at the factory to minimize the need for adjustments. Final adjustments
must be made on side to insure proper alignment.
1. Motor plate horizontal adjustment hex nuts (P/N 7401248-02)
2. Cross-Arm positioned on top of (2A) mount support brackets
3. Mounting plate vertical adjustment bolt (P/N 7401241-16)

2 Assemble the flexible coupling in accordance with the following Installation
instructions. The coupling should be mounted with both hubs mounted
inward as shown in Figure 6-9 below. NOTE: Place the coupling guard
ring over the bearing housing before installing the drive motor. Refer
to section 6.5 for more details.

3 Inspect both driving (motor) and driven (Contherm
™
) shafts and hub bores.
Verify that the keys fit shafts properly.
Mount both hubs of the flexible coupling to the shafts, securing only one hub. The other hub will be used to perform
minor spacing adjustments if necessary.
4 Loosen the outside hex nut (P/N 7401248-02) on each of the four threaded rods (P/N 7401836) that secure the motor
plate assembly to the vertical mount. Refer to Figure 8.
Use the vertical adjustment bolt (P/N 7401241-16) to lower the motor plate assembly until the shaft ends of the motor
and Contherm
™
are close to touching but not in contact.
5
Align the hub on the motor shaft with the hub on the Contherm
™
. Adjust the motor in all axes, both parallel and angular.
Alignment consists of aligning the outside diameter of the hubs with a straight edge (or laser alignment tool) along the
front edge and at a 90
°
interval without rotating the shaft.
Side-side adjustment can be made by loosening the bolts holding the motor to the plate and adjusting the set screws
located on both sides of the motor feet.
Front-to-back and tilt adjustments can be made by adjusting the hex nuts on the horizontal threaded rod.
6 Use the vertical adjustment bolt to raise the motor plate assembly if required.
7 Check the alignment of the hubs again and make any required adjustments. Before tightening nuts and bolts, ensure
that the distance of the bolt holes of the hubs are equal to that of the bolt holes of the elastomer elements. Once
proper distance is obtained, firmly tighten all nuts and bolts.
8 Place half of the flexible coupling’s elastomer element around the hubs and secure with the self-locking cap screws. The
elastomer element will space the other hub. It is important to have the cap screw locking the first hub to the shaft and
ensure that it is properly tightened. Now secure the other hub to the shaft.
9 Mount the other half of the elastomer element to the hub and tighten all screws.
