Installation
b) Attach the other indicator (A) so that the indicator rod comes into contact with the inner

2. Rotate the pump coupling half (X) in order to check that the indicators are in contact with
the driver coupling half (Y) but do not bottom out.
3. Adjust the indicators if necessary.

Pump-to-driver alignment instructions

Perform angular alignment for a vertical correction
1. Set the angular alignment indicator 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
reading value
is...
Negative
Positive
1. Shims

end of the driver coupling half.
This indicator is used to measure angular misalignment.
Then...
The coupling halves are farther apart at the bottom than at the top. Perform one of
these steps:
• Add shims in order to raise the feet of the driver at the shaft end.
• Remove shims in order to lower the feet of the driver at the other end.
The coupling halves are closer at the bottom than at the top. Perform one of these
steps:
• Remove shims in order to lower the feet of the driver at the shaft end.
• Add shims in order to raise the feet of the driver at the other end.
