(c)  
At elevator hinge fitting No. 2, install hinge bearing bolt with head inboard. Place washer under bolthead and nut, then tighten nut 90 to 100 pound-inches. Align nut with cotter pin hole without exceeding 190 pound-inches, then install cotter pin.

(d)  
At elevator hinge fittings locations No. 3 and 5, instal1 hinge bearing bolt with heads outboard. Place washer under bolthead and under nut. At elevator hinge fitting No. 6 location, install hinge bearing bolt with head outboard. Place washer under bolthead and washer and bonding jumper under nut. Clean surface to provide electrical bonding. At all three hinge locations, tighten nut 60 to 85 pound-inches. Align nut with cotter pin hole without exceeding 140 pound-inch, then install cotter pin.

(4)  Secure elevator hoisting adapter to elevator front spar at hinge fitting No. 4 location (Fig. 404).
C.  Remove elevator systems A and B hydraulic power (Ref 27-31-0).
D.  Check that rigging pin E-5 is installed in aft control quadrant (Fig. 405).
6.  Install Elevator
A.  Refer to Fig. 403 and attach elevator to stabilizer as follows:
NOTE:  All bolts attaching elevator hinge fitting halves to elevator front spar are to be tightened 70 to 80 pound-inches.
(1)  
Position elevator at stabilizer trailing edge.

(2)  
Insert washer under head of each hinge fitting mounting bolt.

(3)  
Clean surfaces to provide electrical bonding and place bonding jumper under lower inboard bolthead at hinge fitting No. 1 and lower outboard bolthead at hinge fitting No. 6.

(4)  
Install hinge fitting mounting bolts (four places each fitting). Tighten mounting bolts 70 to 80 pound-inches.

B.  Remove hoisting adapter from elevator front spar.
C.  At elevator hinge fitting No. 4 location, attach hinge fitting to elevator front spar and stabilizer trailing edge. Tighten bolts attaching hinge fitting to elevator front spar 70 to 80 pound-inches (Fig. 403). Install plate attach bolts to stabilizer trailing edge rib with heads inboard.

At stabilizer trailing edge ribs No. 1, 2, 3, and 4, adjust bulb seal to maintain

0.02 +0.01/-0.01-inch clearance between seal and side of stabilizer trailing edge rib (Detail B).

(4)  
At stabilizer trailing edge ribs No. 2, 4 and 6, adjust bulb seal to maintain +0.03/-0.00-inch interference between seal and aft face of stabilizer trailing edge rib (Detail C).

E.  Attach balance panels to elevator by installing six bolts up through each elevator nose. Ensure each hinge seal is properly installed before tightening bolts (Fig. 406).
CAUTION:  WHEN ATTACHING BALANCE PANEL TO ELEVATOR, ENSURE IDLER HINGE IS DEFLECTED DOWNWARD FROM STABILIZER SUPPORT BEAM.
F.  Connect tab pushrods and tab lockout mechanism as follows (Fig. 408):
(1)
