Gaging the Crimping Chamber
This inspection requires the use of a plug gage conforming to the diameters in Figure 5. TE does not
manufacture or market these gages. To gage the crimping chambers, proceed as follows:
1. Remove traces of oil or dirt from the crimping chambers and plug gage.
2. Mate the dies until it is evident that the dies have bottomed, then HOLD in this position. Do NOT force
the dies beyond initial contact.
3. 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. Refer to Figure 5.
4. Now align the NO-GO element and try to insert it straight into the same crimping chamber. The NO-
GO element may start entry but must not pass completely through as shown in Figure 5.
If the crimping chambers conform to the gage inspection, the die assembly is considered dimensionally
correct and should be lubricated with a THIN coat of any good SAE 20 motor oil. If not, the die assembly
must be repaired before returning it to service. See Section 6, REPLACEMENT AND REPAIR.
For additional information concerning the use of the plug gage, refer to Instruction Sheet 408-7424.
