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
A unit is in parallel alignment when the parallel indicator (P) does not vary by more than
0.05 mm | 0.002 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...
Negative
Positive
4. Slide the driver carefully in the appropriate direction. Make sure to slide the driver evenly.
Failure to do so can negatively affect horizontal angular correction.

Then...
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.
Then...
The driver coupling half (Y) is to the left of the pump coupling
half (X).
The driver coupling half (Y) is to the right of the pump coupling
half (X).
