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.

NOTICE:

1. Shims

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 (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.
