3. Insert the stripped wire.
4. Cycle tool to complete crimp. Remove crimped
terminal or splice.
Check These
Areas for
Cracks
Check Die Areas
for Cracks
NOTE
i
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.
6. INSPECTION/MAINTENANCE
DANGER
Make sure hydraulic pressure is released and
power supply is disconnected before following
inspection and maintenance procedures, unless
otherwise specified in the procedure.
Check for Excessive
Wear at Pivot Pin
and Latch Pin
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.
6.1. 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.
6.2. Visual Inspection
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.
Figure 4
NOTE
i
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.
6.3. Crimping Head Check- Out Procedure
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:
A. Electric Hydraulic Pump 1583660- [ ]
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.
2. Inspect pivot pin holes and latch pin holes for
wear. Replace parts, as needed.
B. Foot Hydraulic Pump 1583659- 1
Depress the pressure release pedal.
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.
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).
C. Hand Hydraulic Pump 1583661- 1
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
