CAUTION
IF THE PRESSURE OF THE POWER PUMP IS LESS THAN THE MINIMUM
PRESSURE PERMITTED FOR THE CRIMP TOOL HEAD, THE CRIMP IS
NOT SATISFACTORY.
NOTE: A satisfactory alternative is a power pump that can make:
• A minimum pressure of 9500 PSI to a maximum pressure of 10000 PSI for the AMP
1752787-1 head
• A minimum pressure of 8000 PSI to a maximum pressure of 8400 PSI for the other
AMP heads
• A minimum pressure of 8500 PSI to a maximum pressure of 9000 PSI for the Daniels
heads.
(3) Make a selection of a release agent from Table 7.
(4) Examine the crimp tool equipment.
(a) Do a check of the operation of the crimp tool and power pump as specified by the
manufacturers instructions.
(b) Release the hydraulic pressure from the crimp head.
(c) Examine the crimp head for:
• Contamination
• Cracks
• Damage
• Worn parts
• Leaks
Make sure that:
• The crimp head is clean
• The crimp head and crimp dies do not have damage
• The crimp tool equipment does not have worn parts
CAUTION
CRIMP TOOLS THAT HAVE DAMAGE, ARE DIRTY, OR HAVE WORN
PARTS MUST NOT BE USED. UNSATISFACTORY PERFORMANCE OF
THE SPLICE CAN OCCUR.
(5) Examine the dies for the correct alignment in the crimp head.
Make sure that the alignment dot on the nest die and the alignment dot on the indenter die are on
the same side of the crimp head. Refer to Figure 6.
NOTE: For the normal setup of the tool, the nest side goes in the yoke, and the indenter die goes
in the anvil.
NOTE: A satisfactory alternative is to reverse the dies from the normal setup to make the
assembly of the splice easier in some confined areas.
