A.Install the 11C4643   firewall fixture on the upper firewall (01-152) (SIN 84401) and the lower firewall (01-372) (SIN 84501). Refer to Figure 502 and do as follows:
(1)Prepare to attach the 11C4643   firewall fixture to the upper firewall as follows:
WARNING:
ALWAYS USE APPROVED EQUIPMENT AND PROCEDURES TO LIFT PARTS. STAY OUT FROM BELOW LOADS. IF THE PARTS ACCIDENTALLY MOVE OR FALL, THEY CAN CAUSE AN INJURY OR KILL YOU.
(a)Attach an overhead hoist to the hoist rings (item 40) and lift the 11C4643   firewall fixture.
(b)Make sure to disengage all clamps (items 31, 38, and 39), then loosen the knurled knobs (item 43) to release the lower bar hook (item 22) and upper bar hook (item 32) through the head press fit bushings (items 33 and 34) to let the lower and upper firewalls attach to the clamping mechanisms.
(c)Put the 11C4643   firewall fixture on the 11C3237   restrain fixture that is already seated on the 11C4643   firewall fixture.
(d)Lower the 11C4643   firewall fixture to align it on the top surface of the 11C3237   restrain fixture and attach it with the two locking L pins (item 42) and the four socket head cap screws (item 63).
(2)Attach the 11C4643   firewall fixture to the upper and lower firewalls. Refer to Figure 502 and do as follows:
(a)Carefully lower the 11C4643   firewall fixture until the three protuberant points on the internal surface of the lower firewall touch the locator block pin (item 18) and locator lower pins (item 20) and until the three protuberant points on the internal surface of the upper firewall touch the upper block locator back, front, and center inboards (items 11 and 14).
(b)Carefully adjust the 11C4643   firewall fixture to make sure that there is contact between surfaces of the two protuberant points on the side of the lower firewall and the locator center pins (item 19), and the two protuberant points on the side of the upper firewall and the upper block locator back and center inboard (items 10 and 14).
(c)When the protuberant points of the lower firewall contact each other, turn the handle (item 21) inwards to close the lower bar hook (item 22) and pull it up to support the bottom surface of the lower firewall, then hand tighten the knurled knob (item 43) to secure the position of the lower bar hook (item 22).
(d)When the protuberant points of the upper firewall contact each other, turn the handle (item 21) inwards to close the upper bar hook (item 32) and pull it up to support the internal top surface of the upper firewall, then hand tighten the knurled knob (item 43) to secure the position of the upper bar hook (item 32).
(e)Complete the clamping of the lower firewall by engaging the two vertical hold down clamps (item 38) and three horizontal spanners (item 39). If needed adjust the position of the spindles (item 41) with the hexagonal nuts (item 66).
(f)Complete the clamping of the upper firewall by engaging the toogle clamps (item 31) and three horizontal spanners (item 39). If needed adjust the position of spindles (item 41) with the hexagonal nuts (item 66).
NOTE:
At this point, both firewalls will be attached and secured by the clamping mechanisms of the fixture.
