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 onto the cable, unthreaded end first, and
slide it up and into the pipe below the latch pin.

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 10)

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 11)  A little black tape
may be helpful holding the

washers in place while
performing the next step.

Lift the mounting ring and
insert the latch pins, com-

plete 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 adjustment tube.  Repeat for the other two hoisting
cables.

2.4.9

  Repeat the tightening of the three cables with one

worker pulling as hard as possible on each cable as
another worker pushes the terminal fitting against the
adjustment tube.

2.4.10

  Make a small loop in each cable below the

fitting and secure the loop with a U-bolt cable clamp.
Position the U-bolt clamp 1/2" to 3/4" below the terminal
fitting. Securely tighten the nuts on the U-bolt clamp.
(See Figure 12)  Cut off the excess cable leaving about
6 in. below the clamps.  Tape the ends of the cables for
a distance of about one inch to prevent fraying.
