Mounting the coupling motor to the driven shaft
The motor can be mounted to the driven shaft with or without a mounting tool,
but the use of a mounting tool is recommended since it makes the work easier.
Ensure that the full clamping length is used, by for example measuring and marking
the driven shaft. This is of particular importance if the driven shaft has a stress
relieving groove. See
Fig. 36
,
Fig. 37
and
Table 14
.

4.
Install the assembly tool by passing the tie rod through the centre of the motor,
and screw it into the driven shaft by using a wrench at the key grip at the end
of the assembly tool. Assemble the washer and then the nut tight to the bearing
retainer (3). See
Fig. 40.
5.
Pull the motor onto the shaft by turning the nut on the mounting tool until the
length stated in the
Table 14
