Step 5. Loosen the top 2 bolts on the strut mount with a 9/64
Allen wrench. Loosen and remove the 2 bottom bolts from the
strut mount. Remember to hold on to the strut mount when
removing the bolts. Place the 2 nuts, bolts, and washers in the
small parts container.
Step 6. Remove the flex drive cable from the stuffing box.
Step 7. Lubricate the flex drive cable thoroughly with heavy
grease, including the forward, square-shaped part of the flex
drive cable that inserts into the collet.
Step 8. Reinstall the lubricated flex drive cable. Ensure that the
squared end is engaged inside the collet.
Step 9. When reinstalling the flex drive, ensure that the holes
for the set screws are accessible from the side so the set screws
can be easily tightened with a 5/64 Allen wrench.
Step 10. Reinstall the lower shaft drive strut into the strut
mount. Reinstall the 2 lower bolts and loosely tighten.
Step 11. Loosely tighten the 2 upper bolts on the strut mount.
Ensure that the rudder support is straight and that the lower shaft
drive strut is in line with the stuffing box. Tighten all 4 strut
mount bolts.
Step 12. Lubricate the propeller shaft and reinstall. Ensure that
the 2 brown nylon spacers are reinstalled on both sides of the
shaft drive strut. Reinstall the 2 set screws on the brass ferrule
using Threadlock.
Step 13. Reinstall the rudder into the rudder strut. Ensure that
the nylon washers are reinstalled between the rudder shaft and
the rudder strut on the bottom and the rudder shaft and the rud-
der control horn on the top.
