Boeing F4B-1 - Flotation Gear

41. INSTALLATION TYPE A-3 BOMB RACK-Left Wing (Reference
Fig. 25): a. If the bomb rack has not been previously installed punch the blue
dots on the under side of the lower left wing and re-tap the holes. Install the bomb
rack brackets on the wing, using the spacer blocks to keep the bomb rack horizontal.
b. Install the bomb rack on the brackets.
c. Install the control cable rasings on the under side of the wing and connect
to the stops on the wing fittings and bomb rack, attaching the short casing to
the salvo (or selective) release stop and the long casing to the arming control
stop. Insert the cables into their casings, first passing them over the pulleys.
d. Connect the arming control cable to the lower connection on the inner
arming handle, which is located on the right hand side of the cockpit. Connect
the opposite end to the cable in the casing from the rack. Place the arming handle
and rack in the safe position, cut he cable to the required length, allowing ½ inch
slack, and serve into the arming c ontrol clevis on the bomb rack.
e. Connect the bomb release cable to the lower bomb release handle on the
left hand side of the cockpit. Connect the opposite end to the cable in the casing
from the bomb rack. Cut and serve the cable into the release control clevis on
the bomb rack, allowing ½ inch slack.
42. INSTALLATION TYPE A-3 BOMB RACK-Right Wing (Reference
Fig. 25): a. The installation of the Type A-3 rack on the right wing is similar to
left wing installation except as follows:
Connect the long cable casing to the salvo (or selective) release stops on the
wing fitting and rack, and the short casing to the arming control stops.
The outer arming handle and the upper bomb release are used for the right
wing bomb rack.
43. INSTALLATION TYPE C-3 BOMB RACK (Reference Fig. 25): a.
Install the bomb rack brackets on the fittings located on the front and rear spars
under the fuselage. Install the T rails on the brackets and attach the bomb rack
to the rails.
b. Place the inner arming handle and the bomb rack in the safe position.
Attach the upper arming cable to the safe connection on the arming handle and
the lower cable to the armed connection. Connect the release control cable to the
lower bomb release handle, located on the left hand side of the cockpit. Serve the
cables to the clevises on the bomb rack, allowing ½ inch slack. Attach the cables
as follows: Left-release; center-safe; right-armed. (See Fig. 25).
44. WING TIP FLARES INSTALLATION: If the flares have not been in-
stalled previously, punch the four blue dots which will be found on the under side
of each lower wing tip and re-tap the holes with a 10-32 USF tap. Bolt the flare
brackets in place, securing the bolts with lockwashers. Connect the flare lead
terminals to the brackets. (See Fig. 24).
45. MAINTENANCE: a. All cables are to be kept coated with graphite
grease. Oil all bearing points occasionally.

46. INSTALLATION (Reference Fig. 26 and 27): a. To install the flotation
bags, lace to the support flaps and connect the hose to the CO2 tubes. Be sure
to bond the hose connection. Fold the sides of the bags lengthwise across each
other (A, Fig. 26). Then fold the ends crosswise, the rear tip being folded last
(B, Fig. 26). The doors are then installed, the cable release blocks and release
rods connected by joining the hooks, and the rod pushed into place. The release
rods are secured with the lockwire as follows: Before the doors are installed, bend
the wire "U" shaped and hook it over the inboard release r.od guide. After the
doors are installed and the release rod in place, pass one end of the wire through
the release cable eye and twist the wire ends together until snug. Do not use
larger than .025 annealed copper wire as this safety must be broken to release the
flotation bags. See that the retrieving wires are connected.
