5.2. Daily Maintenance

1. Remove dust, moisture, and other contaminants with a clean brush, or a soft, lint-free cloth. Do NOT

use objects that could damage the dies.

2. When the dies are not in use, store them in a clean, dry area.

5.3. Periodic Inspection

Regular inspections should be performed by quality control personnel. A record of scheduled inspections

should remain with the dies and/or be supplied to supervisory personnel responsible for the dies. Though

recommendations call for at least one inspection a month, the inspection frequency should be based on the

amount of use, ambient working conditions, operator raining and skill, and established company standards.

The inspections should be performed in the following sequence:

Visual Inspection

1. Remove accumulated dirt, grease, and foreign matter by immersing the dies in a suitable commercial

degreaser that will not affect paint or plastic material.

2. Make sure all die holding components are in place. Refer to the parts list in Figure 4 if replacements

are necessary.

3. Check all bearing surfaces for wear. Remove and replace worn components.

4. Inspect the crimp sections for flattened, chipped, cracked, worn, or broken areas. If damage is

evident, the dies must be repaired before returning them to service. See Section 6, REPLACEMENT

AND REPAIR, for information on obtaining customer repair service.

Gaging the Wire Barrel Crimping Chamber

This inspection requires the use of a plug gage conforming to the dimensions shown in Figure 3. To gage

the crimping chamber, refer to Figure 3, and proceed as follows:

1. Remove traces of oil or dirt from the crimping chamber and plug gage.

2. Mate the dies until it is evident that they have bottomed.

3. Align the GO element with the crimping chamber. Push element straight into the chamber without

using force. The GO element must pass completely through the crimping chamber.

4. Check the crimping chamber with the NO-GO element in the same manner as Step 3. The NO-GO

element may start entry, but must not pass completely through the crimping chamber.

If the dies conform to the gage inspection, they are considered dimensionally correct. If not correct, refer

to Section 6, REPLACEMENT AND REPAIR, for information on obtaining customer repair service.

For additional information regarding the use of a plug gage, refer to Instruction Sheet 408-7424.

6. REPLACEMENT AND REPAIR

controlled to prevent lost time when replacement of parts is necessary.
