1. INTRODUCTION
This instruction sheet provides operation and
maintenance instructions for Hydraulic Crimping Head
1752786--1. See Figure 1.
The crimping head accepts interchangeable die sets
for a variety of terminals and splices for large wire
sizes --4/0 through 1000 MCM range. Refer to the
instructions packaged with the specific die sets for
compatible products, wire ranges, strip dimensions,
and application procedures.
The crimping head is designed and recommended for
use with the Foot Hydraulic Pump 1583659--1; Hand
Hydraulic Pump 1583661--1; or the Electric Hydraulic
Pump 1804700--1 (110Vac) or 1804700--2 (220 Vac).
Read these instructions and all applicable references
before inserting any die set assemblies and crimping
any terminals or splices.
Dimensions on this sheet are in metric units [with
U.S. customary units in brackets]. Figures and
illustrations are for reference only and are not
drawn to scale.
Reasons for reissue of this instruction sheet are
provided in Section 7, REVISION SUMMARY.
2. DESCRIPTION (Figure 1)
Main components of Hydraulic Crimping Head
1752786--1 include a “C”--head, which houses the
stationary die, a cylinder which contains the head’s
hydraulic chamber, a piston (ram) which holds and
controls the moving die, and a quick--disconnect
coupling (cylinder half) which mates with the coupling
on the hose to release or supply pressure. A dust cap
covers the quick--disconnect coupling.
3. INSTALLATION
3.1. Head Installation
Prior to installing the head, ensure that the pump
and hose being used are working properly, and
are adjusted to and rated at 68948 kPa
[10,000 psi]. An incorrectly adjusted or rated
pump/hose could result in severe tooling
damage, as well as personal injury.
1. Release the hydraulic pressure to the hose.
Disconnect electric power unit from power supply.
2. Remove protective dust caps.
3. Thoroughly clean the coupling on the
pump/hose and the coupling on the crimping head.
4. Mate both quick--disconnect couplings and
tighten the collar of the coupler assembly on the
hose.
Oil flow must be unobstructed between the power
unit and the crimping head. Ensure that all
couplings are fully mated and tightened.
If a crimping head must be removed after the
power unit was in operation, be sure to release
the pressure in the hydraulic system. When using
Hydraulic Power Unit 1804700--[ ],
DISCONNECT THE POWER UNIT FROM THE
POWER SUPPLY. When using Hydraulic Foot
Pump 1583659--1 or Hydraulic Hand Tool
1583661--1, depress the pressure release pedal
to release pressure.

3.2. Die Installation/Removal
A. Die Installation
To avoid personal injury, do NOT accidentally
depress the footswitch or handle control when
installing or removing dies.
Operating the head WITHOUT the crimping dies
installed will damage the “C”--Head or ram.
1. Back off the set--screws in the head and ram
(ram must be advanced to gain access to the
set--screw). Refer to Figure 2.
2. Insert dies in the head and ram, ensuring that
the “flats” on the die shanks are facing the
set--screws (see Figure 2).
3. Tighten the set--screws.
4. Slowly close the dies to ensure proper
alignment.
5. Complete the cycle and return the ram to the
“down” position.
B. Die Removal
To avoid personal injury, do NOT accidentally
depress the footswitch or handle control when
installing or removing dies.
Operating the head WITHOUT the crimping dies
installed will damage the “C”--Head or ram.
1. Back off the set--screw in the C--Head and
remove the stationary die.
2. Raise the ram slightly to gain access to the
set--screw in the piston (ram).
3. Back off the set--screw in the piston (ram) and
remove the moving die.
4. CRIMPING PROCEDURE
The following procedure provides only general
information concerning crimping. Refer to the
instructions packaged with the dies and power unit for
detailed information, including wire stripping
dimensions and instructions for positioning terminals
and splices in the dies.
1. Insert terminal or splice in the stationary die
according to the instructions packaged with the
dies.
2. Activate the power unit to advance the dies and
hold the terminal or splice in place.
3. Insert stripped wire into the terminal or splice.
4. Activate the power unit to complete the crimp.
5. INSPECTION/MAINTENANCE
Make sure hydraulic pressure is released and
power supply is disconnected before following
inspection and maintenance procedures, unless
otherwise specified in the procedure.
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:
SCare, amount of use, and handling of the head;
SType and size of products crimped;
SDegree of operator skill; and
SEnvironmental 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 every
month or 1,000 cycles, whichever comes first.
Inspect the metal surfaces for nicks, cracks,
scratches, and excessive wear, especially where
sliding contact occurs. Refer to Figure 3. Inspect for
cracks especially at the corners of the “C”--head and
around the top of the cylinder.
5.1. Cleaning
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.

Areas for
Cracks
5.2. Crimping Head Check- Out Procedure
If the ram fails to retract 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, release pressure in the power unit.
If the ram retracts, the trouble is not in the crimping
head. If ram does NOT retract, refer to Section 6,
RETURN/REPAIR.
Replacement parts are listed in Figure 4.
6. RETURN/REPAIR
Order replacement parts through your Tyco
Electronics Representative, or call 1--800--526--5142,
