RHT 2749-CC Hand Crimp Tool Hand Crimp Tool Eng. No. RHT 2749-CC (Replaces 19285-0025) Application Tooling Specification Sheet Order No. 64001-5200 FEATURES % % % % A full cycle ratcheting hand tool ensures complete crimps Long handles for comfortable crimping with reduced crimping force A precision user-friendly terminal locator wire stop holds terminals in the proper crimping position Single color-coded crimp pocket eliminates the possibility of using the wrong pocket SCOPE Products: InsulKrimp Female Fully Insulated Quick Disconnect 24-26 AWG Conductor Crimp Only. Testing Mechanical The tensile test, or pull test, is a means of evaluating the mechanical properties of the crimped connections. The following charts show the UL specifications for various wire sizes. The tensile strength is shown in pounds and indicates the minimum acceptable force to break or separate the terminal from the conductor.

JAWS OPEN Crimping Terminals TERMINAL 1. There are 2 tab locator blades supplied with the tool. One is for .187 and .250 tabs; the other is for .205 tabs and .110 tabs. Make sure the proper blade is installed on the top of the locator and the other is stored on the bottom of the locator. TAB 2. Push the terminal onto the tab locator all the way to the stop in LOCATOR LOCATOR the color-coded nest. The barrel of the terminal should be up Figure 1 (See Figure 1). 3. Partially close the tool to hold the terminal in place (See Figure 2). 4. Insert the properly stripped wire into the terminal barrel (See Figures 2 and 3). Cycle the tool. Note: The tamper-proof ratchet action will not release the tool until it has been fully closed. 5. Remove the crimped terminal and inspect for proper crimp location. Molex offers a Crimp Inspection Handbook for closed barrel industrial product. See the Molex Website or contact your sales engineer.

Remove dust, moisture and other contaminants with a clean brush or a soft, lint-free cloth. LOOSEN 2. Do not use any abrasive materials that M4 SCREW could damage the tool. 3. Make certain all pins, pivot points and 3/32” HEX bearing surfaces are protected with a WRENCH thin coat of high-quality machine oil. Do not oil excessively. This tool was Figure 4 engineered for durability, but like any other equipment, it needs cleaning and lubrication for a maximum service life of trouble-free crimping. Light oil (such as 30 weight automotive oil) used at the oil points shown in Figure 4 every 5,000 crimps or 3 months will significantly enhance the tool life and ensure a stable calibration. 4. When the tool is not in use, keep the handles closed to prevent objects from becoming lodged in the crimping dies, and store the tool in a clean, dry area. Miscrimps or Jams Should this tool ever become stuck or jammed in a partially closed position, Do Not force the handles open or closed. The tool will open easily by lifting the ratchet release lever. See Figure 5.

Listed below are the steps required to adjust the crimping force of the hand tool to obtain proper crimp conditions: 1. 2. 3. 4. 5. 6. Remove the screw and plastic cover washer. Note the setting wheel position. Lift the setting wheel off the axle. Turn the eccentric axle with a screwdriver. Turning the eccentric axle counterclockwise (CCW) will increase handle force. Replace the setting wheel to the axle, aligning the nearest notch in the setting wheel to the dowel pin. Replace the plastic cover washer and screw. Check the crimp specifications after tool handle preload force is adjusted. PIN GAUGE IN CONDUCTOR CRIMP Tool Calibration A certificate of calibration (see last page) was supplied with the tool. To recalibrate this tool, pin gauge measurements should be taken in each conductor nest and compared to this chart. The tool should be lubricated prior to recalibration to ensure consistent measurements. Handle preload is factory set to 25-45 lbs. See How to Adjust Tool Preload to recalibrate.
