Part assemblies
In the context of this subsection the term
"driver" applies to a motor, gear, steam turbine, fluid
drive, clutch, and hydraulic power recovery turbine
(HPRT). The term "turbine" is short for steam
turbine; it does not apply to the HPRT.
This section describes the work that must be
performed to assure that baseplates (or soleplates)
are level. It also outlines the steps to be taken to
assure alignment of multiple baseplates (or
soleplates). The Outline drawing gives dimensions
and any other references necessary for installation
of baseplates and/or soleplates.
4.2.1 Leveling Tools and equipment
Besides hand tools, the tasks of leveling and
aligning baseplates (or soleplates) require:
1) Lifting equipment, including plastic-coated soft
cables
2) Precision straight edge
3) Threaded leveling screws for leveling baseplate
(if baseplate is so equipped) and/or small
metallic shim blocks, each approximately 1 inch
(25 mm) thick, one for each bolt hole in
baseplate or soleplates
4) Precision machinist level or equivalent tool
5) Optical alignment equipment such as an
alignment laser or jig transit that is capable of
measuring to 0.001 in (0.02 mm)
6) Dial indicator
7) Indicator bracket
4.2.2 One baseplate for entire train of units
Where your baseplate is designed with two or more
sets of mounting pads which accommodate the
entire train of units (for example, pump, driver, and
fluid drive) the manufacturing process for the
baseplate ensures alignment of every set of
mounting pads; thus, you need only level such a
baseplate on its foundation as directed by the
procedure below, anchor it down, and you are ready
to grout.
Before beginning the leveling work as outlined below,
you must remove all units, except the pump, from
their mounting pads. These pads must be vacant
while both leveling and grouting the baseplate.
Among the illustrations that highlight the instructions,
there is the baseplate top view figure, which shows
the pump mounted and two sets of mounting pads
A-B and C-D vacant; a typical example of a
baseplate that is ready for leveling. Of course, your
baseplate (see Outline drawing in section 8.) could
include an additional set of pads or where only the
driver and pump make up the entire train; your
baseplate would be less the innermost set of pads,
which are labeled C-D in the baseplate top view
figure. Regardless of how many sets of mounting
pads your baseplate may have, the leveling
procedure is essentially the same. Proceed as

1) Verify that your foundation as described under
section 4.3, has had ample curing time;
otherwise it may not support weight of pump
train.
2) To assure sufficient grouting, provide for a
minimum space of 25 mm (1 in.) between
baseplate and foundation by placing shim blocks
adjacent to each foundation bolt hole or
underneath each leveling screw in the baseplate.
3) Set baseplate with pump on shims and/or
leveling screws, bending anchor bolts as
necessary to align them with holes in baseplate.
Pump feet and their hold down bolts are
inaccessible with lagging in place.
4) Remove insulation covers, if installed, from top
half of pump.
5) To eliminate any torsional affect that the pump
might exert on baseplate, loosen hold down
bolts at each pump foot.
6) Thoroughly clean exposed edges of pad at each
pump foot and surface of all mounting pads.
7) Level baseplate using optical alignment
equipment or machinist level on shims and/or
leveling screws within the required leveling
gradient of 0.05 mm per 305 mm (0.002 in. per
12 inches). If a machinist level is used, ensure
that the baseplate is leveled lengthwise and
crosswise at both ends. Then tighten down
anchor nuts and recheck for nominal gradient. If
