1. INTRODUCTION
Hydraulic Hand Tool 59974-1 is designed for crimping the terminals and splices listed in Figure 1. Read these
instructions thoroughly before using the hand tool.
NOTE
Dimensions in this instruction sheet are in metric units [with U.S. customary units in brackets]. Figures and illustrations are for
identification only and are not drawn to scale.
Reasons for reissue of this instruction sheet are provided in Section 7, REVISION SUMMARY.
2. DESCRIPTION (Figure 1)
The hand tool has a stationary lever and a movable lever. These levers are compressed to pump hydraulic fluid
behind the ram, moving it forward and thereby closing the dies. After the crimping is complete, the movable
lever is turned to depress the plunger, and the moving die retracts to its original position, completing the
crimping cycle.
PROPER USE GUIDELINES
Cumulative Trauma Disorders can result from the prolonged use of manually powered hand tools. Hand tools are intended for occasional use and low
volume applications. A wide selection of powered application equipment for extended-use, production operations is available.

3. DIE INSERTION AND REMOVAL
1. Pull out the latch pin and open the yoke. See Figure 1.
2. Advance the ram slightly to gain access to the moving die setscrew. Note that the stationary die is
held in place by a setscrew.
3. Before inserting the dies, refer to the instruction sheet packaged with the dies for detailed instructions:
insert or remove dies, as necessary, by following the procedures given in the instruction sheet.
4. CRIMPING PROCEDURE
1. Strip the wires to the dimensions specified in the instructions packaged with the dies (see Figure 1).
2. Insert the terminal or splice in the stationary die according to the instruction sheet packaged with the
dies.
DANGER
Ensure latch pin is fully inserted before operating hand tool.
3. Pump the movable lever until the moving die grips the terminal or splice.
CAUTION
Do not deform the wire barrel of the terminal or splice.
4. Insert the stripped wire into the wire barrel of the terminal or splice.
5. Continue pumping the moveable lever. There may be a slight audible click, indicating that the pump
has shifted into the high-pressure stage. Continue pumping the moveable lever. When the dies have
bottomed, there will be an audible “pop”. This indicates that the crimp is complete.
CAUTION
Potential damage to the tool may occur if the following Step 6 is not taken.
6. Retract movable die by opening the movable handle to the full open position, turn the movable handle
(to actuate striker), DO NOT TURN THE MOVABLE HANDLE WHILE IN THE CLOSED POSITION
AS YOU WILL DAMAGE THE PLUNGER (PRESSURE RELEASE), compress handles to depress
plunger (pressure release). Movable die will now retract. See Figure 1.
7. Remove the latch pin, open the yoke, and remove the crimped terminal or splice.
NOTE
If the terminal or splice sticks in the die after crimping, apply a rocking action to remove it from the die.
8. Inspect the crimped terminal or splice according to the inspection procedure in the instruction sheet
packaged with the dies.
5. MAINTENANCE AND INSPECTION
It is recommended that a maintenance and inspection program be performed periodically to ensure dependable
and uniform terminations. Though recommendations call for at least one inspection a month, frequency of
inspection depends on:
1. The care, amount of use, and handling of the hand tool.
2. The presence of abnormal amounts of dust and dirt.
3. The degree of operator skill.
4. Your own established standards.
The hand tool is inspected before being shipped; however, it is recommended that the tool be inspected
immediately upon arrival at your facility to ensure that the tool has not been damaged during shipment.
5.1. Daily Maintenance
1. Hand tool should be immersed (levers partially closed) in a reliable commercial degreasing compound
to remove accumulated dirt, grease, and foreign matter. When degreasing compound is not available,
tool may be wiped clean with a soft, lint-free cloth. Do NOT use hard or abrasive objects that could
damage the tool.

2. Make certain that the retaining pins are in place and that they are secured with retaining rings.
CAUTION
Do not remove the retaining pins as permanent damage to the tool could result.
3. All pins, pivot points, and bearing surfaces should be protected with a THIN coat of any good SAE 20
motor oil. Do NOT oil excessively.
4. When the tool is not in use, keep levers closed to prevent objects from becoming lodged in the dies.
Store the tool in a clean, dry area.
5.2. Hydraulic Fluid Level Inspection (Figure 2)
1. Turn the tool upside down and clamp it in a vise so that the tool levers are in an upright position.
2. Release all pressure in the tool according to Step 6 of Section 4, CRIMPING PROCEDURE.
3. Turn the movable lever, and allow the lever to close until it stops. Be sure not to depress the plunger
when closing the lever.
NOTE
Keep lever in CLOSED position for remaining steps in this procedure.
4. Loosen the setscrew in cap of the stationary (reservoir) lever. See Figure 1.
5. With a view from the lever grip end, turn the lever COUNTERCLOCKWISE and remove the entire
reservoir lever to expose the bladder.
6. Remove the magnetic filler plug. If the bladder is full, no further check is necessary and the tool can
be re-assembled. If fluid level is low, proceed to the next step.
7. Fill the bladder with fluid. Recommended fluid is Dexron II, which is a transmission fluid available in
automotive parts and department stores. Use care to prevent air bubbles from forming while pouring
the fluid.
8. Refill the bladder to point of overflow, and replace the filler plug.
9. Re-assemble the stationary lever and tighten the cap setscrew. The tool is now ready for use.
Figure 2
5.3. Periodic Inspection
It is recommended at least one inspection a month. The inspection frequency should be based on the amount
of use, ambient working conditions, operator training and skill, and your company's established standards.
Dexron is a trademark.

Lubrication
Keep all pins, pivot points, and bearing surfaces lubricated with SAE 20 motor oil as follows:
Tool used in daily production-lubricate daily
Tool used daily (occasionally)-lubricate weekly
Tool used weekly-lubricate monthly
Wipe excess oil from tool, particularly from crimping area. Oil transferred from the crimping area onto
certain terminations may affect the electrical characteristics of an application.
Visual Inspection
1. Make certain all retaining pins are in place and secured with retaining rings. If replacements are
necessary, refer to parts listed in Figure 3.
2. Inspect head assembly for worn, cracked, or broken areas. If damage is evident, return the tool for
evaluation and repair. See Section 6, REPLACEMENT AND REPAIR.
Crimping Pressure Inspection
Check the crimping pressure to ensure that dies are fully bottomed before pressure is reduced by the
internal bypass valve. The inspection should be performed using each set of dies that will be used in the
head.
1. Install the dies according to Section 3, DIE INSERTION AND REMOVAL, and the instruction sheet
packaged with the dies.
2. Select the wire and terminal or splice for the dies being used.
3. Place the terminal or splice in the dies according to the instruction sheet packaged with the dies.
4. Perform the crimping procedure as described in Section 4, CRIMPING PROCEDURE, Steps 3
through 5. Do not release the hydraulic pressure at this time.
5. Check the clearance between bottoming surfaces of the crimping dies. If clearance is 0.025 mm
[.001 in.] or less, crimp pressure is satisfactory. If clearance exceeds 0.025 mm [.001 in.], crimp
pressure is considered not satisfactory. See Section 6, REPLACEMENT AND REPAIR.
If the tool conforms to these inspection procedures, lubricate it with a THIN coat of any good SAE 20
motor oil and return it to service.
6. REPLACEMENT AND REPAIR
Customer-replaceable parts are listed in Figure 3. A complete inventory should be stocked and controlled to
prevent lost time when replacement of parts is necessary. Parts other than those listed should be replaced by
TE Connectivity to ensure quality and reliability. Order replacement parts through your TE Representative, or
call 1-800-526-5142, or send a facsimile of your purchase order to 717-986-7605, or write to:
