(b) Apply a small drop of adhesive to one end of the cut cord. If excess is applied, strike
cord on a hard surface to shake off excess.
(c) Join ends of cord as soon as possible. Position loose ends in splicing fixture alignment
guide. Ensure cord is not twisted. Slide ends of cord along guide until ends are in
contact. Hold in contact with firm pressure on the bond for 10 to 30 seconds.
(d) After 30 seconds of cure, remove adhesive residue from surface of cord by wiping with
clean, dry rag or by scraping with smooth plastic or brass tool, using care not to cut or
scuff cord surfaces.
(e) Allow adhesive to cure 1 hour minimum at room temperature before flexing or stretching.
(f) After cure time of 1 hour, flex the cord bonded joint and inspect for lack of bond. If lack
of bond is observed, repeat splicing procedures with new packing cord as outlined in
steps (2)(a) through (2)(f).
(3) Waterproof bonded joint. Brush a coating of Loctite waterproofing solution over the bond
line. Care should be taken to apply just enough solution to cover the bond line completely
around the cord. Prevent air bubbles from forming in the coating, which will make the
coating porous.
(4) Allow coating to cure for 10 minutes. If after 10 minutes the coating is still tacky, the silicone
grease that will be applied prior to installation will ensure satisfactory results.
(5) Check that the spliced packing properly fits the groove on the bronze bar (46, Sheet 5).
(6) Retain packing in safe place to prevent contamination until installation.

g. Splice new packing (34, Sheet 3) for aft stern tube bearing (33). Use splicing procedure outlined in
paragraph e., using John Crane zip joint packing (34) 5/32 inch diameter.
h. Clean propeller hub bore (Sheet 5) and bronze bar gland (45) mating surfaces with cleaning solvent
and rag. Ensure no dirt particles or other foreign matter is left.
