Swing Base Installation
Introduction
The Drive One Swing Base is a welded steel structure designed
to support a motor and a right angle Type DB, shaft mounted
drive. The swing base itself is a length of square cross-sectional
tubing with plates welded to it for the motor and drive. The
motor and drive plates are machined and are supported by
gussets for additional strength. A torque arm attaches to the
tube section near the motor end of the swing base.
Supporting the Swing Base
The torque arm connection lug prevents the swing base from
lying flat on the ground; therefore, a supporting structure is
required for mounting the gear drive and motor to the swing
base. This structure is typically built from wood and is unique to
each swing base. All gussets have a 19 mm (0.75 inch)
diameter hole for securing the swing base to the supporting
structure.
Mounting Gear Drive to Swing Base
It is standard procedure to mount the drive to the swing base at
the Factory. These instructions are to be followed when field
mounting of the drive to the swing base is required. Use of
broad, flat shims between the gear drive and mounting plate
are recommended to prevent distortion of the housing when the
drive is bolted down. Jacking screw holes are provided in gear
drive housing to aid in fixing the shims. Begin at the low speed
shaft end and level across the length and then the width of the
gear drive. Use a feeler gauge to insure that all pads are
supported. Bolt down the drive to the torque specified in Table
1, Page 4.
Mounting Motor and Coupling Alignment
Shims are provided for motor mounting. Holes must be drilled
into the swing base motor plate for mounting of the motor. Step
blocks are also provided for some small frame motors. Use a
feeler gauge to ensure that all motor pads are firmly seated.
Motor mounting needs to be done in conjunction with coupling
alignment to control angular and offset misalignment. Refer to
the coupling manufacturer’s manual for specific instructions.
Bolt down the motor to the torque specified in Table 1, Page 4.
Coupling Guard
The coupling guard must be trimmed in order to fit the height
and shaft extension requirements. Refer to the coupling guard
installation manual for instructions on trimming the guard. After
the guard has been trimmed holes can be drilled in the
coupling guard plate on the swing base. The guard can then
be bolted down to the plate.
Lifting the Swing Base Assembly
After the drive, motor, and coupling have been mounted to the
swing base, the completed assembly can be lifted into position
for installation on the driven shaft. The motor eyebolt and the
lifting holes on the drive housing can be used as cable
attachment points. The motor eyebolt is strongest when the
cable pull is vertical. To insure that cable pull on the motor
eyebolt is vertical, use of a spreader bar is recommended. See
the sketch below. To ensure safety, chains or a sling should be
placed behind the torque arm connection.

Mount the gear drive to the driven shaft (See Page 2). Secure
the torque arm to the foundation per the instructions in
