2. DESCRIPTION
Latch Pin
Yoke
Main components of the crimping head are: a yoke
which houses the stationary die and retains the
terminal assembly for crimping, a removable latch pin
which allows pivoting of the yoke on the pivot pin
(typically required for splice terminations), a cylinder
which contains the head’s hydraulic chamber, a piston
(ram) which holds and controls the moving die, and a
quick connect/disconnect coupler which mates with
the coupler on the hose to release or supply pressure.
Pivot Pin
To avoid injury when using hydraulic crimping
equipment, observe the following precautions:
- Do NOT modify the crimping equipment in any
way.
- Use only dies, terminals, and wire specified for
the head.
DANGER

3. CRIMPING HEAD INSTALLATION
Each crimping head is shipped with a coating of
lubricating oil to prevent rust and corrosion. Wipe the
oil off before installing the crimping head on the power
unit. Note that the crimping head is shipped without
oil inside the cylinder. To install crimping head,
proceed as follows:
1. INTRODUCTION
This instruction sheet provides application, inspection,
and maintenance procedures for Crimping Head
1752877--1. (see Figure 1). This crimping head uses
interchangeable crimping dies and is used to crimp
products listed in Figure 2. The instructions include
general information for the insertion of dies and the
crimping procedure. Refer to instructions packaged
with specific die sets for compatible products, wire
ranges, strip dimensions, and application procedures.
Make sure that hydraulic pressure to the hose is
released and that power supply is disconnected
to electric power unit, if applicable.
DANGER
1. Remove protective dust caps from both quick
connect/disconnect couplers.
Dimensions on this sheet are in millimeters [with
inches in brackets]. Figures and illustrations are
for reference only and are not drawn to scale.
NOTE
2. Thoroughly clean coupling area of hose
assembly and crimping head. See Figure 1.

3. Hold hose in vertical position to prevent oil
spillage. Attach hose to coupling section on head.
Thread properly and tighten securely.
4. Insert moving (lower) die, which serves as the
indenter, into ram well, making sure that moving
die is properly oriented to mate with stationary die.
Tighten setscrew.
Oil flow must be unobstructed between power
unit and crimping head. Make sure that all
couplers are fully mated and tightened.
CAUTION
!
5. Close yoke and secure with latch pin.
If crimping head must be removed after being in
production, pressure must be released in the
hydraulic system before head is removed.
- If using Electric Hydraulic Pump 1583660 -[ ],
DISCONNECT POWER UNIT FROM POWER
SUPPLY.
- If using Foot Hydraulic Pump 1583659 -1,
depress pressure release pedal, or if using Hand
Hydraulic Pump 1583661 -1, activate the
pressure release knob.
NOTE
6. Slowly close dies to ensure proper alignment.
7. Complete the cycle and return the ram to the
DOWN position.
i
Always ensure that the latch pin is fully inserted
or damage may occur to yoke, dies, or latch pin.

Avoid personal injury. When operating power unit,
exercise caution while holding terminals, splices,
or wire near crimping area.
DANGER
4. DIE INSERTION AND REMOVAL (Figure 3)
Avoid personal injury. When using power unit,
exercise caution to avoid accidently depressing
foot pedal or handle control when installing or
changing dies.
DANGER
The following crimping procedure provides general
information. Refer to instructions packaged with
individual die sets for specific products, wire sizes,
strip dimensions, positioning of terminals and splices
in the dies, and crimping procedures.
4.1. Die Insertion
Never operate the power unit without having a
crimping head attached to the hose.
Make sure that matched die set, terminal, and wire
size are compatible. With crimping head properly
installed, refer to die set instructions, and
insert/change die set as follows:
NOTE
i
1. Remove latch pin and open yoke on crimping
head.
1. Insert terminal or splice in the stationary (upper)
die according to instructions packaged with the
dies. Make sure the latch pin is secure before
activating the power unit.
2. Loosen setscrew in yoke. Refer to die set
instructions and insert stationary (upper) die which
includes the nest area into well of yoke. Tighten
setscrew.
2. Slowly advance moving (lower) die with short,
quick strokes until terminal or splice is secure.

If the splice or terminal sticks in the die after
crimping, apply a rocking action to remove the
crimped terminal or splice from the die. Do not
use damaged product.

power supply is disconnected before following
inspection and maintenance procedures, unless
otherwise specified in the procedure.
Figure 4
Each crimping head is assembled and inspected
before shipment. It is recommended that the crimping
head be inspected immediately upon its arrival at your
facility, and at regularly scheduled intervals, to ensure
that the crimping head has not been damaged during
handling. Frequency of inspection depends upon the
following: care, amount of use, and handling of the
head; type and size of products crimped; degree of
operator skill; and environmental conditions.
Once a year, or every 7,500 cycles (whichever
comes first), the hydraulic head should be
returned to Tyco Electronics for magnetic particle
inspection. Additionally, inspect and service the
head (as described in Figure 4) every month or
1,000 cycles. Refer to Instruction Sheet
408 -8909.
NOTE

6.3. Crimping Head Check-Out Procedure
6.1. Cleaning
If the ram fails to return to the DOWN position after
completion of a crimping cycle, the cause may be in
the crimping head. To determine whether or not the
trouble is in the crimping head, proceed as follows:
Remove accumulations of dirt and grease on the
crimping head, especially in areas where dies are
installed and terminals are crimped. Clean the entire
head frequently with a clean, lint--free cloth.
A. Electric Hydraulic Pump 1583660-[ ]
6.2. Visual Inspection
Press the retract/release button on the hand remote
pendant or foot remote, and hold for several seconds.
This will release any pressure in the hydraulic system.
If the ram returns to DOWN position, the trouble is
NOT in the crimping head. If ram does not return,
ensure that the coupler is fully engaged. If coupler is
engaged and ran still does not go DOWN, return the
crimping head to Tyco Electronics for repairs.
Refer to Figure 4 and proceed as follows:
1. With hydraulic pressure released, inspect the
assembled head for nicks, scratches, and cracks.
Inspect for cracks especially at the corners of the
yoke and around the top of the cylinder.
B. Foot Hydraulic Pump 1583659-1
2. Inspect pivot pin holes and latch pin holes for
wear. Replace parts, as needed.
Depress the pressure release pedal.
C. Hand Hydraulic Pump 1583661-1
3. Activate power unit. Raise ram to UP position.
Inspect flat and round surfaces of ram for galling
(fretting or wear by friction), cracks, or oil leakage.
Release pressure and make sure that ram retracts
smoothly.
Activate the pressure release knob.
7. REPLACEMENT AND REPAIR
Customer--replaceable parts are listed in Figure 5. A
complete inventory can be stocked and controlled to
prevent lost time when replacement of parts is
necessary. Order replacement parts through your
Tyco Electronics Representative, or call
4. If head shows evidence of galling, cracks, oil
leakage, or rough cycling, return the crimping head
to Tyco Electronics for repairs. (Refer to Section 7,
REPLACEMENT AND REPAIR).
