2. Refer to Section 4, CRIMPING PROCEDURE,
and crimp the center contact accordingly.
3. Using a crimp height comparator, measure the
crimp height as shown in Figure 5. If the crimp
height conforms to that shown, the die assembly is
considered dimensionally correct. If not, return the
dies to Tyco Electronics for evaluation and repair
(refer to Section 8, DIE REPLACEMENT).
B. Gaging the Ferrule Crimping Chamber
This inspection requires the use of a plug gage
conforming to the dimensions in Figure 6. Tyco
Electronics does not manufacture or market these
gages. To gage the ferrule crimping chamber,
proceed as follows:
1. Close the jaws until the dies have bottomed,
then HOLD the frame handles in this position. Do
NOT force the dies beyond initial contact.

element must pass completely through the
crimping chamber.
3. 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.
4. Repeat Steps 2 and 3 for the insulation ferrule
section of the crimping chamber.
NOTE
i
Insert the gage element for the insulation ferrule
section into the back of the crimping chamber.
The GO element for this section will not pass
completely through the crimping chamber.
6. CRIMP HEIGHT ADJUSTMENT (Figure 7)
The frame assembly ratchet mechanism features an
adjustment wheel with numbered settings. If the crimp
height is not acceptable, adjust the ratchet as follows:
1. Remove the lockscrew from the ratchet
adjustment wheel.
2. With a screwdriver, adjust the ratchet wheel
from the opposite side of the frame.
3. Observe the ratchet adjustment wheel. If a
tighter crimp is required, rotate the adjustment
wheel COUNTERCLOCKWISE to a
higher–numbered setting. If a looser crimp is
required, rotate the adjustment wheel
CLOCKWISE to a lower–numbered setting.
4. Replace the lockscrew.
5. Make a sample crimp and measure the crimp
height. If the crimp height is acceptable, secure the
lockscrew. If the dimension is unacceptable,
remove lockscrew and continue to adjust the
ratchet, and again measure a sample crimp.
