(3) Then the marine gear flange coupling is rotated 90, 180 and 270 degrees
with the feeler blade being moved around the flange again in each successive
position. If the alignment is correct, the feeler gauge will fit snugly, with the same
tension, all around the flange coupling.
(4) If the alignment varies during rotation, then further alignment is necessary,
or the marine gear and shaft couplings could be checked for improper face runout.
Face runout on the marine gear output flange can usually be corrected by
repositioning the coupling on its spline. Shaft coupling runout is usually due to an
inaccuracy of taper fit or key interference.
