32-63 Float Installation (continued)
C. Packing
1. Install floats per Section 32-63 Part B.
2. Spread deflated float outboard of skid tube. Vacuum as much air as possible from
each float chamber through topping valves. Smooth out wrinkles.
3. Lightly dust float and inside float cover with talcum powder.
4. Refer to Figure 32-7 and Figure 32-8 Detail A. At girt forward edges, fold float
perpendicular to skid tube; tuck material under and aft of float as shown.
5. Refer to Figure 32-8 Detail B. At girt aft edges, fold float perpendicular to skid tube;
lay material over and forward of float as shown.
6. Refer to Figure 32-8 Detail C. Loosen lacing cords securing float cover to inboard
girt. Detach, align, and secure inboard hook and loop fasteners.
NOTE
If possible, roll float into cover with the assistance of six or
seven people.
7. Refer to Figure 32-8 Detail D. Align hoses and valve cover flaps. Roll float from
outboard edge toward skid tube, as tightly as possible. Hold float on top of skid.
8. Apply A257-7 lubricant to mating surfaces of float cover and (outboard) girt snaps.
Button snaps, and secure hook and loop fasteners.
9. Refer to Figure 32-8 Detail E. Verify lacing cords are installed in cover grommets
in crossover (“ladder” lacing) method shown. Tighten cords starting at the aft
skid extension working forward: at each segment, pull cords tight or until material
edges join, but do not overtighten near valves. Tie cord ends in double square knots
(4 alternating overhand knots).
10. Refer to Figure 32-8 Detail F. Tuck-in cord ends and secure hook and loop fasteners.
Secure hook and loop fasteners at end caps.
11. Verify all fasteners are properly secured. Verify floats are rolled tight, with no
lumps or loose areas.
