(Replaces 19284-0023)
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
 Insulation crimp adjustment allows a precise insulation crimp.
SCOPE
VibraKrimpFemale Non-Insulated Quick Disconnects, 24-26 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.

OPERATION
Open the tool by first closing the jaws sufficiently for the ratchet mechanism to
release.
Crimping Terminals
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.
2. Push the terminal onto the tab locator all the way to the stop in the nest. The barrel of the terminal should be up. 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 Figure 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 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.

Maintenance
It is recommended that each operator of the tool be made
aware of, and responsible for, the following maintenance
steps:
1. Remove dust, moisture and other contaminants with a
clean brush, or soft, lint-free cloth.
2. Do not use any abrasive materials that could damage
the tool.
3. Make certain all pin, pivot points and bearing surfaces
are protected with a thin coat of high quality machine
oil. Do not oil excessively. The 64003-7100 (RHT-4753) 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)
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 will
increase handle force.
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.

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 (See Figure 5) to recalibrate.

CAUTION: Repetitive use of this tool should be avoided.
Warranty
This tool is for electrical terminal crimping purposes only. This tool is made of the best quality materials. All vital components are
long-life tested. All tools are warranted to be free of manufacturing defects for a period of 30 days. Should such a defect occur, we
will repair or exchange the tool free of charge. This repair or exchange will not be applicable to altered, misused or damaged tools.
This tool is designed for hand use only. Any clamping, fixturing, or use of handle extensions voids this warranty.
Hand held crimping tools are intended for low volume, prototyping, or repair requirements only.
CAUTION: Molex crimp specifications are valid only when used with Molex terminals, applicators and tooling.
