8. With crimping jaws bottomed, check the insulation barrel section of the crimping chamber as
described in Steps 4 and 5.
If the crimping chamber conforms to the gage inspection, the tool is considered dimensionally correct, and
should be lubricated with a THIN coat of any good SAE 20 motor oil. If not, the tool must be returned for further
evaluation and repair. Refer to Section6, REPLACEMENT AND REPAIR.
For additional information regarding the use of a plug gage, refer to Instruction Sheet 408-7424.
5.5. Ratchet Inspection
The ratchet feature on the hand tools should be checked to ensure that the ratchet does not release
prematurely, allowing the jaws to open before they have fully bottomed. Obtain a 0.025 mm [.001 in.] shim that
is suitable for checking the clearance between the bottoming surfaces of the crimping jaws. Proceed as follows:
1. Select the maximum size wire for the tool and a terminal or splice.
2. Position the terminal or splice and wire between the crimping jaws as described in Section 3.
3. Hold wire in place and squeeze tool handles until the ratchet releases. Hold the handles in this
position, maintaining just enough tension to keep the jaws closed.
4. Check the clearance between the bottoming surfaces of the crimping jaws with the 0.025 mm [.001 in.]
shim. If the clearance is 0.025 mm [.001 in.] or less, the ratchet is considered satisfactory. If the
clearance exceeds 0.025 mm [.001 in.], the ratchet is out of adjustment and must be repaired. Refer to
Section 6, REPLACEMENT AND REPAIR.
