When the reading value is...
Then...
Positive
The coupling halves are closer together on the right side
than the left. Perform one of these steps:
•
Slide the shaft end of the driver to the right.
•
Slide the opposite end to the left.
4.4.5.3 Perform parallel alignment for a vertical correction
Before you start this procedure, make sure that the dial indicators are correctly set up.
A unit is in parallel alignment when the parallel indicator (P) does not vary by more than as measured at
four points 90° apart at the operating temperature.
1.
Set the parallel alignment indicator (P) to zero at the top-center position (12 o’clock) of the driver
coupling half (Y).
2.
Rotate the indicator to the bottom-center position (6 o’clock).
3.
Record the indicator reading.
When the read-
ing value is...
Then...
Negative
The pump coupling half (X) is lower than the driver coupling half (Y). Remove
shims of a thickness equal to half of the indicator reading value under each driver
foot.
Positive
The pump coupling half (X) is higher than the driver coupling half (Y). Add shims of
a thickness equal to half of the indicator reading value to each driver foot.
4.
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.
4.4.5.4 Perform parallel alignment for a horizontal correction
A unit is in parallel alignment when the parallel indicator (P) does not vary by more than as measured at
four points 90° apart at the operating temperature.
1.
Set the parallel alignment indicator (P) to zero on the left side of the driver coupling half (Y), 90°
from the top-center position (9 o’clock).
2.
Rotate the indicator through the top-center position to the right side, 180° from the start position
(3 o’clock).
3.
Record the indicator reading.
When the reading value is... Then...
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.
