(b)
Install bolt (11) through hinge plates (20) and elevator hinge (1). Install bolt with head outboard at hinge No. 3, 4, 5, and 6. Install bolt with head inboard at hinge No. 6 if clearances between structures and hinge fitting prevent installation from outboard side. Place a washer (9) under bolthead and a washer (9) under nut (8). For elevator hinge No. 6, place bonding jumper (5) and washer under nut and a washer under bolthead. At hinge No. 6 clean surface to provide electrical bonding. Also, hinge should be assembled so that lubrication fitting on elevator hinge is down (below hinge centerline) when installed.
WARNING: DO NOT GET SOLVENT IN YOUR MOUTH OR EYES, OR ON YOUR SKIN. DO NOT BREATHE THE FUMES FROM SOLVENTS. SOLVENTS ARE HAZARDOUS MATERIALS. REFER TO PRODUCT MATERIAL SAFETY DATA SHEETS (MSDS) AND LOCAL REQUIREMENTS FROM PROPER HANDLING PROCEDURES.
(c)
At all four hinges, tighten nut (8) 60 to 85 pound-inches. Align nut with cotter pin hole without exceeding 140 pound-inches, then install cotter pin (10).
(2)
Position hinge assembly at elevator front spar (3) with boltheads oriented per step (l) and temporarily install three plate bolts (19) at hinge location No. 3 or 4, or two plate bolts (19) at hinge location No. 5 or 6.
(3)
Check that hinge fits flush with shear plate (2) at elevator front spar (3) within 0.015 inch. If not, add or remove shim (4) as required.

(b)
Withdraw plate bolts (19) and remove hinge assembly from airplane.
(c)
Thoroughly clean both faces of shim and face of shear plate using cleaning solvent.
(d)
Bond required thickness of shim to shear plate at elevator front spar using adhesive.
(5)
If step E.(4) was not accomplished, withdraw plate bolts (19) and remove hinge assembly from airplane.
(6)

(7)
Position hinge assembly at elevator front spar (3) and secure to stabilizer trailing edge rib
(21)
as follows:
NOTE: When positioning hinge assembly, check that head of hinge bearing bolt (11) faces outboard at hinge No. 3 thru 6 (No. 6 can be inboard).
(a)
At hinge location No. 3 or 4, install three plate bolts (19) with heads inboard. Place washer (22) under nut (23) and tighten nut 50 to 70 pound-inches (detail C).
