RHT2251-CC Hand Crimp Tool Hand Crimp Tool Operating Instruction Sheet And Specifications Part No. 64001-4900 Eng. No. RHT 2251-CC (Replaces 19285-0023) FEATURES Œ Œ Œ Œ 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 AviKrimp Fully Insulated Quick Disconnect Female Couplers and, Perma-Seal Fully Insulated Snap Plug Receptacles 10 - 16 AWG. 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.

TERMINAL JAWS OPEN Crimping Terminals 1. Adjust the locator up or down until the terminal being run sits flat and straight in the tool. 2. Position the terminal with the barrel facing up into the color-coded nest. Make sure the end of the terminal fits into the locator pocket securely and the front edge of the barrel is flush against the front edge of the locator, (See Figure 1). Figure 1 POCKET OF 3. Partially close the tool to hold the terminal in place (See Figure LOCATOR LOCATOR 2). 4. Insert the properly stripped wire into the terminal barrel (See Figure 2 and 3). The wire insulation will stop against the taper of the terminal. Cycle the tool. Note: The tamper proof ratchet action will not release the tool until it has been fully closed. 5. Remove the crimp and inspect for proper crimp location, and check for insulation closure. Molex offers a Crimp Inspection Handbook for closed barrel industrial product. See our website or contact your sales engineer. 6. If the insulation part of the crimp needs to be adjusted, first loosen the M4 screw on the bottom tool jaw, then insert a 3/32 hex wrench (supplied) into the bottom of the lower die (See Figure 4). A clockwise (CW) rotation decreases insulation crimp while a counter-clockwise (CCW) rotation increases insulation crimp. After adjusting retighten the M4 screw. CONDUCTOR PUNCH WIRE STOP BUILT INTO TERMINAL PUNCH INSERT WIRE WIRE LOCATOR TERMINAL Figure 2 TERMINAL CONDUCTOR ANVIL ANVIL INSERT Figure 3 Note: Whenever crimping without the locator, make sure the seam of the terminal is oriented up or down in the tool if using unbrazed product, as this will provide higher pull force values.

Remove dust, moisture and other contaminants with a SCREW clean brush, or soft, lint-free cloth. 3/32” HEX 2. Do not use any abrasive materials that could damage the WRENCH tool. 3. Make certain all pin, pivot points and bearing surfaces are protected with a thin coat of high quality machine oil. Figure 4 Do not oil excessively. The 64001-4900 (RHT-2251-CC) was engineered for durability, but like any fine piece of equipment it needs cleaning and lubrication for a maximum service life of trouble-free crimping. A 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 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 pressing the ratchet release lever (See Figure 5). How To Adjust Tool Preload (See Figure 5) PRELOAD TEST POINT Over the life of the tool, it may be necessary to adjust tool handle preload force. Listed below are the steps required to adjust the crimping force of the hand tool to obtain proper crimp conditions: 1. Remove the screw and plastic cover washer. Note the setting wheel position. 2. Lift the setting wheel off the axle. Turn the eccentric axle with a screwdriver. 3. Turning the eccentric axle counter-clockwise RATCHET will increase handle force. RELEASE LEVER PUSH UP 4. Replace the setting wheel to the axle, aligning the nearest notch in the setting wheel to the dowel pin. 5. Replace the plastic cover washer and screw. 6. Check the crimp specifications after tool crimp force is adjusted.

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 (See Figure 5) to recalibrate.
