3. Using a crimp height comparator, measure the
wire barrel crimp height as shown in Figure 4. If the
crimp height conforms to that shown in the chart,
the tool is considered dimensionally correct. If not,
return the tool for evaluation and repair (refer to
Section 5, REPLACEMENT AND REPAIR).
For additional information concerning the use of the
crimp height comparator, refer to Instruction Sheet
408-7424.
C. Ratchet Inspection
Obtain a 0.025 [.001] shim that is suitable for checking
the clearance between the bottoming surfaces of the
crimping jaws. Proceed as follows:
1. Select a terminal and maximum size wire for the
hand tool.
2. Position the terminal and wire between the
crimping jaws, as described in Section 3,
CRIMPING PROCEDURE.
3. Holding the wire in place, squeeze the tool
handles together 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. If the clearance is
0.025 [.001] or less, the ratchet is satisfactory. If the
clearance exceeds 0.025 [.001], the ratchet is out of
adjustment and must be repaired.
If the tool conforms to these inspection procedures,
lubricate it with a thin coat of any good SAE 20 motor
oil and return it to service.
