When the reading
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
settings, other values are permitted. The correct tolerances must be used. Failure to do so
can result in misalignment.
Perform parallel alignment for a horizontal correction
Refer to the alignment table in "Permitted indicator values for alignment checks" (see Table of
Contents for location of table) for the proper cold alignment value based on the motor
temperature rise and the pump operating temperature.
A unit is in parallel alignment when the parallel indicator (P) does not vary by more than
0.10 mm | 0.004 in. 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.
