inspected immediately upon arrival at your facility to

ensure that no damage occurred during shipment.

4.1. 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, mate them, and

store in a clean, dry area.

4.2. Periodic Inspection

1. Remove accumulated dirt, grease, and foreign

matter by immersing the dies in a suitable

commercial degreaser.

2. Inspect crimping area for worn, cracked, or

broken surfaces. If damage is evident, return the

dies to Tyco Electronics for evaluation and repair.

Refer to Section 5, REPLACEMENT AND

REPAIR.

4.3. Gaging the Crimping Chamber

This inspection requires the use of a plug gage

conforming to the dimensions shown in Figure 4.

To gage the crimping chamber, refer to Figure 4, and

proceed as follows:

1. Remove traces of oil or dirt from the crimping

chamber and plug gage.

2. Mate the dies but do not apply pressure.

3. Align the GO element with the crimping

chamber. Push the element straight into the

crimping chamber without using force. The GO

element must pass completely through the

crimping chamber.

4. In the same manner, try to insert the NO–GO

element into the crimping chamber. The NO–GO

element may enter partially, but must not pass

completely through the length of the crimping

chamber.

If the dies conform to the gage inspection, they are

considered dimensionally correct. If not, the dies must

be returned to Tyco Electronics for further evaluation

and repair. Refer to Section 5, REPLACEMENT AND

REPAIR.

For additional information regarding the use of a plug

gage, refer to Instruction Sheet 408–7424.
