A full cycle ratcheting hand tool ensures complete crimps
Long handles for comfortable crimping with reduced crimping force
3-nested tool eliminates the need for additional tools
A precision user-friendly terminal locator / wire stop holds terminals in the proper crimping position for each of
the three nests
SCOPE
Perma-Seal Terminals and Splices 10–22 AWG (Rings, Spades, Hooks, 3 and 4-Ways, and Splices).
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 specifications for various wire sizes. The tensile strength is shown in pounds and
indicates the minimum acceptable force to break or separate terminal from the conductor.
The following is a partial list of the product part numbers and their specifications that this tool is designed to
run. We will be adding to this list and an up to date copy is available on www.molex.com
Open the tool by first closing the jaws sufficiently for the ratchet mechanism
to release.
Crimping Terminals
1. Push up on the locator blade and position the terminal with the barrel
facing up into the color-coded nest, centering the barrel in the lower jaw
as shown in Figure 1. Release the locator blade to hold the terminal in
position.
Note: The locator is used to hold the terminal, not to position the terminal.
2. Partially close the hand tool jaws until the connector is held snug in place. See Figure 2.
3. Insert the properly stripped wire into the terminal barrel (See Figure 2 and 3).
4. Complete the crimp by closing the hand tool handles until they release.
Note: The tamper proof ratchet action will not release the tool until it has been fully closed.
5. Lift the locator blade and remove the crimped terminal. Inspect for proper crimp location, and check for
insulation closure. Locator is adjustable up and down to keep terminals straight after crimping. Molex offers
a Crimp Inspection Handbook for closed barrel industrial product. See our website or contact your sales
engineer.

the locator must be removed.
1. Position the splice into the nest.
2. Partially close the tool to hold the splice in place.
3. Insert the properly stripped wire into the splice. The
wires end should butt against the tab in the terminal (See
Figure 4). Cycle the tool.
4. Remove the crimped splice. Inspect for proper crimp
location.

5. Rotate the butt splice terminal 180°, so that the opposite
end of splice is in the nest.
6. Repeat steps 2 thru 4.
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.
Maintenance
It is recommended that each operator of the tool be made
aware of, and responsible for, the following maintenance
LUBRICATION POINTS
(BOTH SIDES)
LIGHT OIL (EVERY 3 MONTHS
OR 5,000 CRIMPS)
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 pins; pivot points and bearing surfaces
Figure
are protected with a thin coat of high quality machine oil.
Do not oil excessively. The 64001-3200 (RHT-5770) 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 5, 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 6).

How to Adjust Tool Preload (See Figure 6)
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 (CCW)
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 handle preload 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
before recalibration to ensure consistent measurements.
Handle preload is factory set to 25-45 LBS. See How to
Adjust Tool Preload (see Figure 6) to recalibrate.
