4. Repeat the previous steps until the permitted reading value is achieved.
Perform parallel alignment for a horizontal correction
A unit is in parallel alignment when the parallel indicator (P) does not vary by more than 0.002 in.
(0.05 mm) as measured at four points 90° apart at the operating temperature.
1. Set the parallel alignment indicator 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 is to the left of the pump coupling half.
Positive The driver coupling half is to the right of the pump coupling half.
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.
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 0.002 in. (0.05 mm) 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.
