COMPLETE ALIGNMENT
A unit is in complete alignment when both
indicators A (angular) and P (parallel) do not
vary by more than .002 in. (.05 mm) as
measured at four points 90° apart.
Vertical Correction (Top-to-Bottom)
1. Zero indicators A and P at top dead center
(12 o’clock) of coupling half Y.
2. Rotate indicator to bottom dead center
(6 o’clock). Observe the needles and
record the readings.
3. Make corrections as outlined previously.
Horizontal Correction (Side-to-Side)
1.
Zero indicators A and P on the left side of
coupling half Y, 90° from top dead center
(9 o’clock).
2. Rotate indicators through top dead center
to the right side, 180° from the start
(3 o’clock). Observe the needle, measure
and record the reading.
3. Make corrections as outlined previously.
4. Recheck both vertical and horizontal
readings to ensure adjustment of one did
not disturb the other. Correct as
necessary.
NOTE: With experience, the installer will
understand the interaction between angular
and parallel and will make corrections
appropriately.
