ASSEMBLY – CRIMP INTO HOUSING
The completed crimp can now be inserted into the appropriate Trio-Tek crimp housing. For larger
wire sizes, no other tooling should be required for this operation; the crimps can be pushed in by
hand. Crimps are assembled into the mould with the retaining tang towards the outer edge of
the housing. With thinner wires, it may be helpful to push onto the back of the crimp with the
Extraction Tool Z80-258.
If it is necessary to remove a crimp once assembled, please see Instruction Sheet IS-28 for details
on the Extraction Tool Z80-258.
TROUBLESHOOTING – MISCRIMPS OR JAMS
Should the tool become
stuck or jammed in a
partially closed position,
Do Not force the handles
open or closed . There is
a ratchet release lever
located inside the
movable handle.
Pressing up on this lever
will release the ratchet,
and the handles should
then easily open. The
jam or miscrimp can then
be removed.
TROUBLESHOOTING – LOW PULL-OFF FORCE
This tool is supplied as new, set to the right preload force necessary to crimp the Trio-Tek
contacts. However, over time, this force may fall off slightly. The tool can be adjusted to cater
for this wear, and raise the preload force to give correct crimps.
If you need to carry out this procedure, Harwin recommend that you crimp a number of samples
before and during adjustment, until the pull-off force achieved exceeds the minimum values
shown on the first page of this instruction sheet.
.
Ensure that the crimp tool
is at the fully open
position
Hold the hand tool as shown in the above figure, and
squeeze the link bar in towards the top of the tool. This
releases the preload adjustment wheel.
