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).
