Crimping Butt Splices 

 

When crimping butt splices, or 3-way and 4-way terminals 
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 
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 

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).
