WARNING
DO NOT HOOK THE TWO SLING HOOKS (1) OR CLEVIS (2) TO THE
THREE EXHAUST LIFTING EYES (3).
THESE LIFTING EYES WILL
BREAK AND CAN CAUSE SERIOUS PERSONAL INJURY, OR DAMAGE TO
THE EXHAUST DUCT (4) OR POWERPACK (5)(FIG. 1-15).
k. Lift the Powerpack from the Tank. You must make all hoisting
movements (i.e., up, down, forward, and backward) slowly and in
approximately one-inch increments to prevent injury to personnel and
damage to the equipment.
To prevent damage to the engine, cable
assemblies, (5) and connectors, do not use any of the connectors (1)
of the electro-mechanical fuel system (2) as handles to position the
powerpack (3) when removing it. You must make sure that you have all
lines, cables, and linkages clear before removing the powerpack (fig.
1-17).
When the sling has leveled and you have freed the powerpack from the
engine mount assembly, the powerpack may swing freely.
Excessive
movement of the hoist, more than one inch at a time, may result in
damage to the engine inlet screen assembly (8) (fig. 1-17).
Lift the sling (6) until you tighten all three chains (9
and 10)(fig. 1-17).
Slowly lift the sling until the rear of the powerpack lifts
slightly from the tank, and then guide the powerpack from
the tank.
Slowly lift the powerpack up and move it to the rear of the
tank in one-inch increments until you have freed the
powerpack from the mount.
Lift the powerpack until it
clears the top of the two sponson fuel tanks.
Since you have removed the powerpack for ground hop, place
it about three feet from the rear of the tank, on wooden
blocks.
When using a M88 or M578 hoist to remove the
powerpack, drive the hoist backward, using a ground guide,
to position the powerpack over the three wooden blocks (4
and 5)(fig. 1-18).
