3 / 6 page 408- 9853 PRO- CRIMPER III Hand Crimping Tool Assembly 90652- 1 3 of 6 Rev C Tyco Electronics Corporation 4. CONTACT SUPPORT ADJUSTMENT (Figure 3) The contact support is preset prior to shipment, but minor adjustment may be necessary. 1. Make a sample crimp and determine if the contact is straight, bending upward, or bending downward. 2. If adjustment is required, loosen the screw that holds the contact support onto the locator assembly. The ratchet has detents that create audible clicks as the tool handles are closed. 3. Place a contact with wire into the proper nest and close the tool handles until the ratchet reaches the sixth click, or until the contact support touches the contact. 4. Slightly loosen the nut that holds the locator assembly onto the tool frame 5. Move the contact support as required to eliminate the bending of the contact. 6. Tighten the nut and close the handles until the ratchet releases. 7. Remove and inspect the contact. 8. Make another sample crimp. If the contact is straight, tighten the contact support screw. If the contact is still being bent during crimping, repeat the adjustment procedure. 5. CRIMPING PROCEDURE This tool is provided with a crimp adjustment feature. Initially, the crimp height should be verified as specified in Figure 4. Refer to Section 6, CRIMP HEIGHT INSPECTION , and Section 7, RATCHET (Crimp Height) ADJUSTMENT, to verify crimp height before using the tool to crimp desired contacts and wire sizes. Refer to the table in Figure 1 and select wire of the specified size and insulation diameter. Strip the wire to the length indicated in Figure 1, taking care not to nick or cut wire strands. Select an applicable contact and identify the appropriate crimp section according to the wire size markings on the tool. Refer to Figure 3 and proceed as follows: 1. Hold the tool so that the back (wire side) is facing you. Squeeze tool handles together and allow them to open fully. 2. Holding the contact by the mating end, insert the contact — insulation barrel first — through the front of the tool and into the appropriate crimp section. 3. Position the contact so that the mating end of the contact is on the locator side of the tool, and so that the open “U” of the wire and insulation barrels face the top of the tool. Place the contact up into the nest so that the movable locator drops into the slot in the contact. Refer to Figure 3. Butt the front end of the wire barrel against the movable locator.
