Dry cleaning solvent (E162) is
flammable and toxic. It can irritate
skin and cause burns. Use only in
well-ventilated area, away from heat
and open flame. In case of contact,
immediately flush skin or eyes with
water for at least 15 minutes. Get
medical attention for eyes.
2.
Remove barrier material and tape covering hole
(6) in tank (7). Remove tape residue from tank.
Use dry cleaning solvent (E162) and cloths
(E135). Wear goggles to protect eyes. Wear
gloves (E186).
Do not puncture or scratch lining
of fuel tank. If lining is broken, fuel
penetrates and activates self-sealing
layers. Activated layers swell and trap
fuel. Activated green spongy material
also contaminates fuel system. This
makes it necessary to replace fuel
tank and flush fuel system.
NOTE
Four different types of aft fuel cells
are used on the helicopter. Each is
interchangeable but has a different
assembly between valve adapter
and cell. Goodyear cells have four
bushings, FPT cells have an adapter
plate, and Uniroyal cells have nothing
between adapter and cell.
3.
Position shim plate (8) or four bushings (9),
adapter (10), and valve (2) with port (4) outboard,
over vent valve (11), on floor of tank (7).
4.
Install four washers (12) and bolts (13).
5.
Connect tube (14) to port (4) of valve (2).
6.
Remove plug from hose (15). Connect hose to
valve (2).
