Tools Be sure that all proper assembly tools are on hand & properly calibrated. 2. Stripping Strip wire inds to 3/16” for 20-32 AWG, taking care not to nick or cut wire strands. Hold insulation & twist strands to eliminate any splaying. 3. Wire Insertion Insert wire into crimp well of contact. Don’t force. Wire strands must be visible through inspection hole. 4. Crimping Using crimp tool & positioner noted above insert wire & contact into locator jaws. Squeeze tool handle complete- ly until ratchet releases. Remove wired contact from tool (Pic. 4). 5. Backshell Preperation Slide backshell/strain relief over jacketed cable or wires in proper order for re-assembly. Contact factory for proper jacketed cable assembly. 6. Contact Preperation Slide wired contact into insertion tool of choice so that the tip of the tool butts against the shoulder of the contact.

CONTACT INSERTION/EXTRACTION INSTRUCTIONS 1. Insertion of Contacts 1. Insertion of Contacts: Insert wired contacts & tool into contact ‘clicks’ into retention clip A straight pull on the wire will assure the contact is properly seated. Note: Isopropyl alcohol maybe used sparingly as a lubricant. 2. Assembly After all contacts are inserted, assemble backshell or strain relief according to Amphenol backshell catalog instructions. 1. Contact Extraction Remove backshell or strain relief from connector. 2. Contact Extraction MIL-DTL-28840 connector contacts are extracted from the rear but released from the front of the connector. Using an extraction tool, slide tool tip into front of con- tact cavity (Mating face of connector, until tool tip engages against contact retention clip. Push plunger with min. force to release contact. Note: Isopropyl alco- hol may be used sparingly as a lubricant. 3. Contact Extraction Pull wired contact from rear grommet of connector. Contact Replacement After replacing contact re-insert starting with assembly instructions number 7.
