straight into the chamber, but do not force it. The
GO element must pass completely through the
chamber.
5. Align the NO–GO element and try to insert it
straight into the same crimping chamber section.
The NO–GO element may begin entry as shown in
Figure 4, but must not pass through the chamber.
If the crimping chamber conforms to the gage
inspection, the tool may be considered dimensionally
correct and should be lubricated with a THIN coat of
any good SAE 20 motor oil. If the crimping chamber
does NOT conform to the gage inspection, the tool
must be returned for further evaluation and repair.
See Section 5, REPLACEMENT AND REPAIR.
For additional information regarding the use of a plug
gage, refer to Instruction Sheet 408–7424.

Inspection of Crimping Chamber
4.3. CERTI-CRIMP Hand Tool Ratchet Control
Inspection
Check the ratchet to ensure that the ratchet does not
release prematurely, allowing the dies to open before
they have fully bottomed. Proceed as follows:
1. Remove traces of oil or dirt from the bottoming
surfaces of the dies.
2. Obtain a 0.025 mm [.001 in.] shim that is
suitable for checking the clearance between the
bottoming surfaces of the dies.
3. Select a splice and
maximum size wire for the
splice.
4. Position the splice in the crimping chamber
according to Section 3, CRIMPING PROCEDURE.
Holding the wire in place, squeeze the tool handles
together until the ratchet releases. Hold the tool
handles in this position, maintaining just enough
pressure to keep the dies closed.
5. Check the clearance between the bottoming
surfaces of the dies. If the clearance is 0.025 mm
[.001 in.] or less, the ratchet is satisfactory. If
clearance exceeds 0.025 mm [.001 in.], the ratchet
is out of adjustment and must be repaired. See
Section 5, REPLACEMENT AND REPAIR.
