Negative
The driver coupling half (Y) is to the left of the pump coupling half (X).
Positive
The driver coupling half (Y) is to the right of the pump coupling half (X).
4.
Slide the driver carefully in the appropriate direction.
NOTICE:
Make sure to slide the driver evenly. Failure to do so can negatively affect horizontal angular
correction.

5.
Repeat the previous steps until the permitted reading value is achieved.
NOTICE:
The specified permitted reading values are valid only at operating temperature. For cold set-
tings, other values are permitted. The correct tolerances must be used. Failure to do so can
result in misalignment. Contact ITT for further information.
4.5.5.5 Perform complete alignment for a vertical correction
A unit is in complete alignment when both the angular indicator (A) and the parallel indicator (P) do not
vary by more than 0.05 mm | 0.002 in. as measured at four points 90° apart.
1.
Set the angular and parallel dial indicators to zero at the top-center position (12 o’clock) of the driver
coupling half (Y).
2.
Rotate the indicators to the bottom-center position (6 o’clock).
3.
Record the indicator readings.
4.
Make corrections according to the separate instructions for angular and parallel alignment until you
obtain the permitted reading values.
4.5.5.6 Perform complete alignment for a horizontal correction
A unit is in complete alignment when both the angular indicator (A) and the parallel indicator (P) do not
vary by more than 0.10 mm | 0.004 in. as measured at four points 90° apart.
1.
Set the angular and parallel dial indicators to zero at the left side of the driver coupling half (Y), 90°
from the top-center position (9 o’clock).
2.
Rotate the indicators through the top-center position to the right side, 180° from the start position
(3 o’clock).
3.
Record the indicator readings.
4.
Make corrections according to the separate instructions for angular and parallel alignment until you
obtain the permitted reading values.
