2.4.6 Install the cable terminal fitting on the cable as
follows:
CAUTION
Handle carefully and do not drop the cable terminal
fittings into mud, dirt, sand, etc. The fittings are sealed
at both ends, oil lubricated, and encased in plastic bags
for the protection of their internal parts.
2.4.6.1 Inspect the end of the hoisting cable. Remove
any tape or wire seizing. The end should be clean-cut,
round, and have no frayed strands.
2.4.6.2 Remove the cable terminal fitting from the
plastic bag.
2.4.6.3 Grasp the cable with one hand about four or
five inches from the end. Hold the fitting firmly in the
other hand with the small tapered end toward the cable.
2.4.6.4 Carefully insert the end of the cable into the
aluminum guide cup in the small end of the fitting. (See
Figure 11)
2.4.6.5 Force the cable
through the fitting. Do not
pull back on the cable once
it is started through the
fitting. As the cable exits,
the plastic sealing plug will
be forced out and may be
discarded.
2.4.7 Repeat the steps in
paragraphs 2.4.4 through
2.4.6.5 for the remaining two
cables.
CAUTION
Make sure all the hoisting
cables are seated in their
respective pulley grooves.
2.4.8 Install one large slotted washer on the top end of
each latch pin. (See Figure 12) A little black tape may
be helpful holding the washers in place while perform-
ing the next step. Lift the mounting ring and insert the
latch pins, complete with washers, into the latch
barrels. While workers hold the ring against the
headframe, pull one of the hoisting cables as tight as
possible by hand and slide the terminal fitting against
the fitting holder. Repeat for the other two hoisting
cables.

2.4.4 Insert the free end of each of the hoisting cables
down through its corresponding latch pin on the mount-
ing ring. Be careful not to loop or kink the cables as
they are being pulled through.
2.4.5 Pull a hoisting cable just slightly tight and straight
out of the pipe below the latch pin. Install the adjust-
ment tube and locking nut onto the cable, threaded end
first, slide it up and thread it into the fitting below the iris
arm. (See Figure 10).
