3.2. Ferrule

1. Slide the ferrule over the cable braid and

contact support sleeve until the ferrule bottoms

against the contact body.

2. Insert contact body through the ferrule

crimping chamber from the FRONT of the tool.

Make sure that the shoulder on the ferrule is

against the edge of the ferrule crimping

chamber. See Figure 3.

Figure 3

3. Holding the contact body and ferrule in place,

actuate tool through a complete cycle to crimp

the ferrule.

4. Removed contact assembly from tool.

4. MAINTENANCE AND INSPECTION

The die assembly is inspected before shipment. Tyco

Electronics recommends that the die assembly be

inspected immediately upon arrival at your facility to

ensure that the die assembly was not damaged

during shipment and that it conforms to the

dimensions provided in Figure 4.

4.1. Daily Maintenance

Tyco Electronics recommends that each operator of

the dies be made aware of—and responsible for—the

following four steps of 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. Make sure the proper screws are in place and

secured.

3. Make certain all surfaces are protected with a

THIN coat of any good SAE 20 motor oil. Do

NOT oil excessively.

When the dies are not in use, store them in a clean,

dry area.

4.2. 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. The

inspection frequency should be based on the amount

of use, working conditions, operator training and skill,

and established company standards. These

inspections should be performed in the following

sequence:

A. Visual Inspection

1. Remove all lubrication and accumulated film

by immersing the dies in a suitable commercial

degreaser that will not affect paint or plastic

material.

2. Make certain all screws, retaining rings, and

die components are in place. If replacements are

necessary, refer to parts listed in Figure 5.

3. Check all bearing surfaces for wear. Remove

and replace worn components.

4.3. Gaging the Crimping Chamber

This inspection requires the use of plug gages

conforming to the dimensions provided in Figure 4.

Tyco Electronics does not manufacture or market

these gages. To gage the crimping chamber, proceed

as follows:

1. Remove traces of oil or dirt from the crimping

chamber and plug gage.

2. Mate the dies until the crimping surfaces have

bottomed; then hold in this position. Do NOT

force beyond initial contact.

3. Insert GO element into the crimping chamber;

but do not force it. The GO element must pass

completely through the crimping chamber. See

Figure 4.

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. See Figure 4.

If the crimping chambers conform to the gage

inspection, the dies may be considered dimensionally

correct and should be lubricated with a THIN coat of

any good SAE 20 motor oil. If the crimping chamber

does NOT conform to the gage inspection, refer to

Section 5 for information on obtaining evaluation and

repair.
