INSTALLING THE COVER NUT
The O-ring (P/N 6230-11) is located on the inside face of the cover nut (Figure 6). During the process of
crimping, the contact or terminal grows in length with the displacement of material. The O-ring allows the
die set to move forward as the contact is crimped. This prevents excessive side load from being applied to
the side of the indenters, reduces wear, and prevents the contact from bending.
Install the cover nut with fingertip pressure only. Turn the nut until you feel the O-ring come in contact with
the die face, then tighten approximately an additional 15°.
NOTE
Do not overtighten the cover nut. Doing so prevents the O-ring from performing its intended purpose.
