4. Holding the splice in place, squeeze tool
handles together until ratchet releases. Allow tool
handles to open and remove crimped splice.
5. Check the splice to ensure that the crimp is
centered on wire barrel and the stripped wires are
fully bottomed in the splice. Refer to Figure 3 for a
properly crimped splice.
CAUTION
!
Damaged product should not be used. If
damaged product is evident, it should be cut from
the wire and replaced with a new one.
5. CRIMP ADJUSTMENT
5.1. Gaging the Crimping Chamber
This inspection requires the use of a plug gage
conforming to the dimensions shown in Figure 4. Tyco
Electronics does not manufacture or market these
gages. To gage the crimping chamber, proceed as
follows:
1. Remove traces of oil or dirt from the crimping
chamber and plug gage.
2. Close the tool handles until it is evident that the
dies have bottomed; HOLD the tool in this position.
Do NOT force the dies beyond initial contact.
3. Align the GO element with the crimping
chamber. Push the element (without forcing it)
straight into the chamber. The GO element must
pass completely through the crimping chamber.
4. Align and try to insert the NO–GO element with
the same crimping chamber. The NO–GO element
may start entry but must not pass completely
through the crimping chamber.
If the crimping chamber conforms to the gage
inspection, the die assembly is considered
dimensionally correct and should be lubricated with a
THIN coat of any good grade SAE 20 motor oil. If not,
the dies or tool frame must be repaired before
returning it to service. See Section 8,
REPLACEMENT AND REPAIR.
For additional information concerning the use of a
plug gage, refer to Instruction Sheet 408–7424.
5.2. CERTI-CRIMP Ratchet
The CERTI–CRIMP ratchet should be checked to
make sure that the ratchet does not release
prematurely allowing the dies to open before they
have fully bottomed. Obtain a 0.025 [.001] shim that
is suitable for checking the clearance between the
bottoming surfaces of the crimping dies.
Proceed as follows:
1. Select a splice and the maximum number of
wires permitted as indicated in the splice wire
combination chart (refer to Figure 1).
2. Position the splice and wire between the
crimping dies, according to Section 4, CRIMPING
PROCEDURE. Holding the splice in place,
squeeze the tool handles together until the
CERTI–CRIMP ratchet releases. Hold the tool
handles in this position, maintaining just enough
pressure to keep the dies closed.
3. Check the clearance between the bottoming
surfaces of the crimping dies. If the clearance is
0.025 [.001] or less, the ratchet is satisfactory. If
clearance exceeds 0.025 [.001], the ratchet is out
of adjustment and must be repaired. See Section
8, REPLACEMENT AND REPAIR.
