4. Repeat steps 1 through 3 until indicator P reads
.002 in. (.05 mm) or less.
5. Re-check both horizontal and vertical readings to
ensure adjustment of one did not disturb the other.
Correct as necessary.
COMPLETE ALIGNMENT
A unit is in complete alignment when both indicators
A (angular) and P (parallel) do not vary by more than
.002 in. (.05 mm) as measured at four points 90° apart.
Vertical Correction (Top to Bottom)
1. Zero indicators A and P at top dead center
(12 o’clock) of coupling half Y.
2. Rotate indicator to bottom dead center
(6 o’clock). Observe the needles and record the
readings.
3. Make corrections as outlined previously.
Horizontal Correction (Side to Side)
1. Zero indicators A and P on the left side of
coupling half Y, 90° from top dead center
(9 o’clock).
2. Rotate indicators through top dead center to
the right side, 180° from the start (3 o’clock).
Observe the needle, measure and record the
reading.
3. Make corrections as outlined previously.
4. Recheck both vertical and horizontal readings to
ensure adjustment of one did not disturb the other.
Correct as necessary.
NOTE: With experience, the installer will
understand the interaction between angular and
parallel and will make corrections appropriately.
GROUT BASEPLATE
1. Clean areas of baseplate that will contact grout.
Do not use an oil-based cleaner because grout will
not bond to it.
2. Build a dam around foundation (Fig. 9A).
Thoroughly wet foundation.
3. Pour grout slowly through grout holes in
baseplate, until level with the top of the dam. The
use of non-shrink epoxy grout is recommended,
follow manufacturers recommendations. If
cementitious grout is used, remove air by puddling
or with a vibrator (Fig. 9A).

Alignment Troubleshooting
PROBLEM PROBABLE CAUSE REMEDY
Cannot obtain horizontal
(Side-to-Side) alignment, angular
or parallel
Driver feet bolt bound
Loosen pump hold down bolts and slide pump and driver
until horizontal alignment is achieved.
Baseplate not leveled
properly, probably twisted.
Determine which corner(s) of the baseplate are high or low
and remove or add shims at the appropriate corner(s) and
realign.
Cannot obtain vertical (Top to
Bottom) alignment, angular or
parallel
Baseplate not leveled
properly, probably bowed.
Determine if center of baseplate should be raised or lowered
and correct by evenly adding or removing shims at the center
of the baseplate.
