b) Attach the other indicator so that the indicator rod comes into contact with the inner end of the
driver's coupling half. This indicator is used to measure angular misalignment.
If your reading value is...
negative
positive
Then...
• raise the driver's feet at the shaft end (add shims), or
• lower the driver's feet at the other end (remove shims).
• lower the driver's feet at the shaft end (remove shims), or
• raise the driver's feet at the other end (add shims).
1 Rotate the pump's coupling half to check that the indicators are in contact with the driver's
coupling half but do not bottom out.
2
Adjust the indicators if necessary.
Pump-to-driver alignment instructions
Perform
angular alignment (vertical correction)
1 Set the angular alignment indicator to zero at the top-center position (12 o’clock) of the
driver's coupling half.
2
Rotate the indicator to the bottom-center position (6 o’clock).
3 Record the indicator reading.
Perform angular alignment (horizontal correction)
5. Repeat the previous steps until the correct reading value is achieved.
