can be mounted to the motor adapter plate. The hubs will be
aligned and come together to the proper gap. To fill the fluid
coupling to the proper oil level, align the mark on the
perimeter of the fluid coupling with the mark in the center of
the inspection window on the bell housing on the side opposite
the low speed shaft extension. To locate the correct mark on the
fluid coupling, begin by aligning the fill hole of the fluid
coupling with the mark in the inspection window. For fill angles
less than 90°, rotate the fill plug upward until the marks line up.
For fill angles greater than 90°, rotate the fill plug downward
until the marks line up. When the proper marks are in-line, fill
the fluid coupling with recommended fluid until fluid appears at
the lip of the fill hole.
Close Coupling
If the drive requires a shaft fan, assemble prior to installing
coupling.
Mount the motor to the motor adapter plate on the bell
housing before installing the coupling. Once the motor is
secured, measure the distance (D) between the end of the
motor shaft and the high speed shaft of the drive, see Figure 3.
Subtract the distance (D) from the length of the spacer coupling
(BE). Then divide this value in half to find the overhang of each
hub. [Ov (BE – D)/2] The overhang will be negative,
this is the amount each hub overhangs the shaft. Once the
overhang is determined, install the hubs according to the
instructions provided with the coupling. Install the spacer
sections and verify the gap is correct. If not, readjust the hub on
the motor shaft. If the coupling is furnished with an interference
fit, readjustment will not be possible, take extra care in making
measurements. After the proper gap is set, finish installing the
coupling per the instructions.
Lifting the Alignment Free Drive
Lifting points are provided on the corners of the motor side of
the bell housing, see Figure 4. Lift by these and the provisions
provided on the drive housing itself to maneuver the drive. DO
NOT lift by the motor lifting eye.
Mounting the Drive
Mount the Alignment Free Drive to the driven equipment per
Page 2. The torque arm must be located on the extension side
of the drive at the foot as shown in Figure 5. Connect the
torque arm to the foundation per the torque arm installation
instructions.
