PRO-CRIMPER III Hand Crimping Tool Assembly 318451-1
1. Flare the cable braid and insert the crimped
center contact into the connector body until the
cable dielectric is against the dielectric inside the
connector body. The flared braid will then fit over
the support sleeve of the connector body.
2. Slide the ferrule forward over the braid until the
ferrule is against the connector body.
3. Place the ferrule in the crimping chamber on the
anvil die so that the shoulder of the connector body
is against the edge of the die. Refer to Figure 4.
4. Holding the assembly in place, close the tool
handles until the ratchet releases.

5. INSPECTION
5.1. Visual Inspection
The crimping dies should be inspected on a regular
basis to ensure that they have not become worn or
damaged. Inspect the crimping chambers for
flattened, chipped, worn, or broken areas. If damage
or abnormal wear is evident, the tool must be
replaced. See Section 8, DIE REPLACEMENT.
5.2. Periodic Inspection
A. Center Contact Crimp Height Inspection
This inspection requires the use of a micrometer with
a modified anvil as shown in Figure 5.
Proceed as follows to check the crimp height of the
center contact:
CAUTION
5. Allow the handles to open fully, and remove the
crimped assembly from the die assembly.
NOTE
1. Select the center contact for the connector.

Damaged contacts should not be used. If a
damaged contact is evident, it should be cut from
the wire and replaced with a new one. Contacts
should not be reterminated.
Tyco Electronics does not manufacture or market
these gages. However TE recommends the
modified micrometer (Crimp Height Comparator
RS-1019-5LP).
