Set the two dial indicators to zero. Then, with
each coupling at full end float, rotate the two coupling
halves in 90 degree increments. Read and record each
dial indicator at 3:00, 6:00, 9:00 and 12:00 o'clock
angular positions of the shaft. Two dial indicator setups,
180 degrees apart, are used to correct for possible, axial
shift of one shaft with respect to the other. Use the
difference in readings between the two indicators to
determine the angular misalignment between the two

coupling halves. Add or remove shims under the feet as
appropriate to correct for misalignment in the vertical
plane. A lateral, angular movement of the unit is required
to correct for misalignment in the horizontal plane.
Continue the angular alignment procedure until the
angular misalignment does not exceed 0.0015-inch. This
may require several iterations.
