Check that coupling centerlines align, by butting
propeller shaft coupler against transmission out-
put flange. Shoulder on propeller shaft coupler
should engage recess on transmission output
flange face with no resistance.
5. If coupling centerlines are not aligned or if cou-
pling faces are more than .003 in. (0.07 mm) out
of parallel, adjust engine mounts as follows:
a. TO ADJUST ENGINE UP OR DOWN: Loos-
en locking nut on mounts requiring adjust-
ment and turn both front mount or rear mount
adjusting nuts equally.
NOTE: Some propeller shaft couplers may not have
a shoulder on mating face. On these installations,
use a straight edge to check centerline alignment.
IMPORTANT: Both front mount (or rear mount)
adjusting nuts must be turned equally to keepen-
gine level from side to side.
