2. Crimping:
a. Put crimping clamp on Splicing Head; hose can be
either to left or right. Pins on inside edge nest in pin
pockets on Splicing Head when clamp is placed at
an angle on head. See Figure 59.
b. Rotate clamp until detents lock clamp in upright
position. If detents do not lock or prevent rotation,
they can be adjusted with screwdriver. See Fig. 60.
c. Clamp is designed to crimp Module to proper height.
Air/hydraulic system has “by-pass” so that it idles
when crimp is complete. Hand pump also has “by-
pass” but is not as noticeable as with air pump. Close
release valve on side of hand pump. Work hand
pump about 5 strokes after Module appears closed.
Watch for wires being cut. Both pumps must be
properly positioned during crimping. Keep output
end of hand pump level or lower than rear. This will
keep air out of hydraulic lines. Instruction labels are
on pumps. If pump does not operate properly, see
“Bleeding Instructions.”
d. Leave clamp in closed position. If crimp is complete,
wires will be cut and will come off easily. Do not
grasp all wires at once or you will damage the
retainer spring. Take only one-quarter to one-third of
them, lift and move straight up, gently. Wires should
be cut; if not, crimp is not complete and additional
pressure is required to cut wires. See Figure 61 .
e. Release pressure on clamp and remove it. To release
pressure on air/hydraulic pump, push back on foot
pedal. To release pressure on hand/hydraulic pump,
open valve on side of pump.
f. Rotate clamp and remove from head.
g. An adjustment on crimping clamp limits return of
pressure plate. This can be set for Module height to
reduce number of strokes required.
h. Remove temporary tie K cable entry is from top.
(Only top Module requires tie.) Second Module
will be terminated in this same position. On cable
entering from bottom, unsnap adapter and place
Splicing Head in next lower position. This will make
it easy to remove module.
i. Module Mounts are used in sets of right and left,
with “R” or “L” on tab. See Figure 62. Craftsman
may identify cable and mark pair counts on mounts
before putting them into place. For uniformality, it is
suggested that cable and binder groups be identified
on matte surface of left mounts and pair counts on
right mounts. Slide mount onto frame ear until it is
seated against vertical frame member. See Figure 62.
Install Mount Sets just before completed Modules
are to be snapped in place for ease in handling.
j. Remove Module from Splicing Head and snap firmly
onto the Mount Set. Support mounts with fingers as
Module is snapped into place.
