- INTRODUCTION Hand Crimping Tools 46673, 46673-1, and 46988 are used to crimp high-temperature and heat-resistant STRATO-THERM terminals and splices onto wire sizes 22 through 14 AWG. NOTE All dimensions on this document are in metric units [with U.S. customary units in brackets]. Figures and illustrations are fo r identification only and are not drawn to scale. Reasons for reissue of this instruction sheet are provided in Section 7, REVISION SUMMARY. 2. DESCRIPTION Each hand tool features an indenter crimping jaw, an anvil crimping jaw, locator, two insulation crimping adjustment pins, and a CERTI-CRIMP hand crimping tool ratchet control. The hand tool has the wire size marked on the BACK side of the tool. The locator positions the terminal or splice between the crimping jaws. The insulation crimping adjustment pins are used to regulate the crimp height of the insulation barrel sleeve. The hand tool ratchet ensures full crimping of the terminal. Once engaged, the ratchet will not release until the tool handles have been FULLY closed. See Figure 1. NOTE The crimping jaws bottom before the CERTI-CRIMP hand crimping tool ratchet control releases. This design feature en sures maximum electrical and tensile performance of the crimp. Do NOT re-adjust the ratchet. 3. CRIMPING PROCEDURE 1. Strip the wire using the recommended strip-length dimensions provided in Figure 2.

- Hold wire in place and close the tool handles FULLY to crimp the terminal or splice. Allow tool handles to open FULLY. Remove the crimped terminal or splice from the crimping jaws. 7. To crimp the other half of the splice, reposition the uncrimped sleeve in the crimping jaws as described in Step 3. Follow Steps 4 through 6 to complete the crimp. NOTE If the splice cannot be turned around to position the uncrimped sleeve in the crimping jaws, turn the tool around. 8. Inspect the crimp. Refer to Figure 6 for a properly crimped terminal and splice. Check the insulation grip on the crimped terminal or splice. Refer to Section4, INSULATION CRIMPING ADJUSTMENT. The hashmark code on the bottom of the wire barrel sleeve created by the tool should match the hashmark code referenced with the appropriate tool. See Figure 6. Figure 6 4. INSULATION CRIMPING ADJUSTMENT The hand tool has three insulation crimping adjustment positions to adjust the wire insulation grip: 1 -Tight, 2- Medium, and 3-Loose. To obtain the desired insulation grip, proceed as follows: 1. Insert insulation crimping adjustment pins into Position 3 as shown in Figure 1. 2. Position terminal or splice in crimping jaws as described in Section 3, Step 3. 3. Insert an UNSTRIPPED wire into only the insulation barrel sleeve of the terminal or splice.

- Perform a test crimp as described in Section 3, Step 6. Remove the crimped terminal or splice and check the insulation support. Bend the wire back and forth once. The insulation barrel sleeve should retain grip on the wire insulation. If the wire pulls out, move the insulation crimping adjustment pins to the next tighter position (Position 2) and proceed to Step 5. If the wire does not pull out, the pins are properly adjusted and the tool is ready for crimping. 5. Perform another test crimp as described in Step 4. Adjust pins, as necessary, until the desired insulation grip is obtained. Do not use a tighter setting than is required. NOTE The insulation crimping adjustment pins must be located in the same adjustment position. 5. MAINTENANCE AND INSPECTION PROCEDURE It is recommended that a maintenance and inspection program be performed periodically to ensure dependable and uniform terminations. Frequency of inspection should be adjusted to suit your requirements through experience and depends on: The care, amount of use, and handling of the hand tool. The presence of abnormal amounts of dust and dirt. The degree of operator skill. Your own established standards. The hand tool is inspected and calibrated before being shipped; however, it is recom mended that the tool be inspected immediately upon arrival to ensure that the tool has not been damaged during shipment. 5.1. Daily Maintenance 1. The hand tool should be immersed (handles partially closed) in a reliable commercial degreasing compound to remove accumulated dirt, grease, and foreign matter. When degreasing compound is not available, tool may be wiped clean with a soft lint-free cloth. Do NOT use hard or abrasive objects that could damage the tool. 2. Make certain that the retaining pins are in place and that they are secured with retaining rings. 3. All pins, pivot points, and bearing surfaces should be protected with a thin coat of any good SAE 20 motor oil. Do not oil excessively. 4. When the tool is not in use, keep handles closed to prevent objects from b ecoming lodged in the crimping jaws. Store the tool in a clean, dry area. 5.2. Lubrication Lubricate all pins, pivot points, and bearing surfaces with SAE 20 motor oil as follows: Tool used in daily production - lubricate daily. Tool used daily (occasional) – lubricate weekly. Tool used weekly – lubricate monthly. Wipe excess oil from tool, particularly from crimping area. Oil transferred from the crimping area onto certain terminations may affect the electrical characteristics of an application. 5.3. Visual Inspection 1. Close tool handles until ratchet releases and then allow them to open freely. If they do not open quickly and fully, the spring is defective and must be replaced. See Section 6, REPLACEMENT AND REPAIR. 2. Inspect head assembly for worn, cracked, or broken jaws. If damage is evident, return the tool for evaluation and repair. Refer to Section6, REPLACEMENT AND REPAIR. 5.4. Gaging the Crimping Chamber This inspection requires the use of plug gages conforming to the dimensions provided in Figure 7. TE Connectivity does not manufacture or market these gages.
- With crimping jaws bottomed, check the insulation barrel section of the crimping chamber as described in Steps 4 and 5. If the crimping chamber conforms to the gage inspection, the tool is considered dimensionally correct, and should be lubricated with a THIN coat of any good SAE 20 motor oil. If not, the tool must be returned for further evaluation and repair. Refer to Section6, REPLACEMENT AND REPAIR. For additional information regarding the use of a plug gage, refer to Instruction Sheet 408-7424. 5.5. Ratchet Inspection The ratchet feature on the hand tools should be checked to ensure that the ratchet does not release prematurely, allowing the jaws to open before they have fully bottomed. Obtain a 0.025 mm [.001 in.] shim that is suitable for checking the clearance between the bottoming surfaces of the crimping jaws. Proceed as follows: 1. Select the maximum size wire for the tool and a terminal or splice. 2. Position the terminal or splice and wire between the crimping jaws as described in Section 3. 3. Hold wire in place and squeeze tool handles until the ratchet releases. Hold the handles in this position, maintaining just enough tension to keep the jaws closed. 4. Check the clearance between the bottoming surfaces of the crimping jaws with the 0.025 mm [.001 in.] clearance exceeds 0.025 mm [.001 in.], the ratchet is out of adjustment and must be repaired. Refer to Section 6, REPLACEMENT AND REPAIR. 6. REPLACEMENT AND REPAIR Customer-replaceable parts are listed in Figure 9. Parts other than those listed should be replaced by TE to ensure quality and reliability.
