1. Set the reverse gear lever in the neutral
position.
2. Remove the bolts whic h hold the bearing
housing (6, Fig. 3) to the housing (7).
Pull the bearing housing aft several milli-
meters (this is faci litated by carefully en-
gaging the lever), insert a knife between
the sea ling surfaces and loosen the basket
carefu lIy so that it remains in contact with
only one of the sealing surfaces.
3. Turn the bearing housing to the desired
position and tighten down the housing.
If the keyway on the shaft is in such a po-
sition after being moved round that the re-
verse gear lever cannot
be
fitted, the shaft
and flange are turned as fo lIows: On the
shaft there is only one keyway so that both
DATA
the lever retainer and the shaft must
be
turned.
a. Remove the spring housing (1, Fig. 3)
and lift out the locking plunger (2).
b. Remove the cover (4) without pulling it
off the shaft.
c. Lift the shaft (3) with cover (4) from the
housing and turn the shaft 1800 (half a·
turn). Turn also the flange (5) half a
turn and fit the shaft.
4. Refit the parts.
If the remote control for the RB reduction-re-
verse gear is fitted, it may not
be
done in such
a way that a constant pressure operates on the
reverse gear control components. In both
"Ahead" and "Astern II positions the remote con-
tro I device must be complete Iy un loaded so that
the prope lIer thrust can maintain the cones in
the reverse gear in the engaged position.
