Dry cleaning solvent (E162) is
flammable and toxic. It can irritate

Four different types of aft fuel cells
are used on the helicopter. Each is
interchangeable but has a different

and cell. Goodyear cells have four
bushings, FPT cells have an adapter
plate, and Uniroyal cells have nothing
between adapter and cell.
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).
Install four washers (12) and bolts (13).
Connect tube (14) to port (4) of valve (2).
