1. Mate the dies until it is evident that they have

bottomed. Hold the dies in this position.

2. Align the GO element with the crimping

chamber. Push element straight into the crimping

chamber without using force. The GO element

must pass completely through the crimping

chamber as shown in Figure 9.

3. Align the NO–GO element and try to insert it

straight into the crimping chamber. The NO–GO

element may start entry but must not pass

completely through as shown in Figure 9.

If the crimping chamber conforms to the gage

inspection, the crimping die is considered

dimensionally correct and should be lubricated with a

THIN coat of SAE 20 motor oil. If not, the dies must

be repaired before returning them to service (see

Section 7, REPLACEMENT AND REPAIR).

For additional information concerning the use of a

plug gage, refer to instruction sheet 408–7424.
