Contact Insertion
Select the proper insertion tool for the size of contact as per table The insertion tool
and procedure are the same for both pin and socket contacts Slide rear accessory
and sleeve over wire bundle Lay wire in groove of insertion tool and slide contact
into front of 1001 until it is properly located in tool probe Insert contact into the
correct hole in the rear face of the grommet Keeping contact in line with the axis of
the hole, apply a smooth even push on the tool until the contact is fully seated in
position Note it is essential that the contact and tool are correctly aligned with the
axis of hole during insertion to prevent damage to contacts Withdraw tool at right
angles to grommet surface until completely free of connector All contacts must be
inserted whether in circuit or not and the appropriate size sealing plug used behind
any contacts that are not wired. Push the sealing plug by hand until it is fully seated.
Contact Removal
CAUTION extra care is required in this operation to prevent damage to the
connector Remove the rear accessory and sleeve and slide back on wire bundle
Select the proper removal tool for the size of contact from table The same tool is
used for both pin and socket contacts Position the removal tool over the contacts to
be removed and push until tool probe is fully bottomed, shown when indicator band
enters insert hole Tool is inserted to first band only when removing pin contacts and
to second band for socket contacts removal Slide the plunger knob forward to
