1. INTRODUCTION
Hydraulic Hand Pump 314979-1 combines the convenience of a hand tool with the power of a bench machine. It
is used primarily for low-volume production or at locations where electrical power sources are not readily
available. See Figure 1.
Heads and dies are available for use in this unit to crimp terminals and splices, in wire size ranges from No. 8
AWG to 1000 MCM. It should be noted that the crimping of terminals and splices in the 600 MCM to 1000 MCM
range will require additional operator effort.
The hand pump can be used as a portable crimping unit. This type of operation provides a large working radius
and accessibility to confined areas.
A complete line of precision-engineered heads and matched die sets is available from TE. Hose assemblies, in
four different lengths, are also sold separately. See Figure 8 for accessory part numbers.
When reading this manual, pay particular attention to DANGER, CAUTION, NOTE statements.

2. DESCRIPTION
2.1. Physical Description
The hydraulic hand pump features a two-speed hydraulic pumping unit. This unit will deliver 4.75 ml [.29 cu in.]
per stroke at high pressure (up to 58608 kPa [8500 psi]), and 120.4 ml [7.35 cu in.] per stroke at 0 to 1379 kPa
[200 psi] for fast ram advance and return. See Figure 2 for hand pump specifications.

The pump is shipped with hydraulic fluid in the reservoir. Refer to Section 5, INSPECTION/ADJUSTMENTS
AND MAINTENANCE, for refilling instructions. If additional fluid is required, it is essential that the proper grade
of high-quality hydraulic fluid be used. Recommended hydraulic fluids and manufacturers of high-grade fluid for
use in the hand pump are listed in Figure 3.
CAUTION
!
NEVER use brake fluid as a substitute for the recommended hydraulic fluid.

2.2. Functional Description (Figure 4)
On the intake stroke (up-stroke) of two-section piston (H and L), hydraulic fluid is drawn from the reservoir (K)
and into intake line (A). See Detail A of Figure 4. The fluid flows past low-pressure intake poppet (B) into the low-
pressure chamber, and it flows past high-pressure intake poppet (F) into the high-pressure chamber.
On the pressure stroke (down-stroke) of two-section piston (H and L), hydraulic fluid in the low-pressure
chamber is directed through spool (C), past outlet poppet (D), and through outlet valve (J) to the crimping head.
See Detail B of Figure 4. Simultaneously, the hydraulic fluid in the high-pressure chamber is directed through
high-pressure outlet poppet (G), past outlet poppet (D), and through outlet valve (J) to the crimping head. This
action causes the moving die to close, holding the terminal or splice in crimping position.
When approximately 1379 kPa [200 psi] is developed (see Detail C of Figure 5), hydraulic fluid from the high-
pressure chamber will cause outlet poppet (D) to shift spool (C), allowing low-pressure hydraulic fluid to be
discharged into reservoir (K). High-pressure hydraulic fluid continues to flow through high-pressure outlet poppet
(G), past outlet poppet (D) and outlet valve (J), and into the crimping head, completing the crimp.
The high-pressure system has a pressure relief valve (M) which is set at the factory to release at between 55160
and 57918 kPa [8000 and 8400 psi]. If the pressure buildup in the high-pressure system exceeds this setting,
pressure relief valve (M) will open, causing the hydraulic fluid to be discharged into reservoir (K).
NOTE
i
DO NOT alter the setting of the pressure relief valve.
Turning the hold/return lever to the return position advances plunger (P) which opens poppet (X). See Detail D of
Figure 5. When poppet (X) opens, hydraulic fluid returns from the crimping head to reservoir (K), for as long as
the lever is in the return position.

3. OPERATION
CAUTION
!
NEVER operate hand pump without having hose and crimping head attached. Refer to Figure 6.
3.1. Preparation
1. Check level of hydraulic fluid in reservoir, and add fluid if required. Refer to Paragraph 5.2.
2. Protective caps are put on crimping heads and hose fittings to prevent dirt from entering the hydraulic
system. Ensure that caps are placed on head and hose fittings when they are disassembled.
CAUTION
!
Never store hand pump without having head or protective cap attached to the hose fittings.

3.2. Attaching Crimping Head to Hose and Hose to Hand Pump
CAUTION
!
Always have lever in the return position when connecting or removing hose couplings or crimping heads.
A. To attach the crimping head, proceed as follows:
1. Thoroughly clean coupling area of hose assembly and crimping head.
2. Remove protective caps.
3. Mate coupling halves and tighten collar (refer to Figure 7).
B. To attach hand pump to hose, proceed as follows:
CAUTION
!
Make sure that the lever is in the return position while connecting coupling halves.

1. Thoroughly clean coupling area of hose assembly and hand pump.
2. Remove protective caps.
3. Mate coupling halves and tighten collar (refer to Figure 7).
4. After the hose has been attached to head and pump, bleed all air from the hydraulic system. Refer to
Paragraph 5.3.
3.3. Insertion of Crimping Dies
The instruction materials packaged with the dies give detailed instructions for die insertion, die adjustments, and
die removal when the dies are used with crimping heads as listed. Insert required crimping dies as instructed.
NOTE
i
All listed die numbers are for complete die sets except for those identified as nests or indenters for SOLISTRAND*
connectors. The interchangeability of nests and indenters for SOLISTRAND connectors requires that these dies be
identified separately.
3.4. Operating Procedure
1. Be certain that crimping dies are properly installed in head. Refer to instruction material packaged with
crimping dies for die insertion instructions.
2. Place terminal or splice in crimping dies. Refer to instruction material packaged with crimping dies for exact
terminal or splice location in dies.
NOTE
i
BE SURE latch pin has been fully inserted before operating pump.
3. Pump lever to activate unit. Continue pumping lever until ram moves up and holds terminal or splice firmly
in place. A sudden decrease in effort required to push lever down will be observed during the initial buildup of
pressure.
4. Insert stripped wire into terminal or splice.
5. Continue pumping until pressure relief valve is activated. A slight decrease in effort required to push lever
down indicates that maximum required crimping pressure has been reached and that crimp is now complete.
6. Move the lever to the return position, and hold the lever in this position. Ram in crimping head will return to
DOWN position, and crimped terminal or splice can be removed.
7. To make additional crimps, repeat Steps 2 through 6 as required.
NOTE
i
Holdlever inthe returnposition longenoughtoallowram tomove downjust enoughtoremove crimpedterminal orsplice.
Return the lever to the hold position for the next cycle.

DO NOT allow hand pump to remain under pressure for extended periods of time.
4. ACCESSORIES
4.1. Crimping Heads
The hand pump uses interchangeable crimping heads. Each crimping head uses interchangeable crimping dies
(with the exception of crimping head 69069, which has integral dies designed for that particular head). The
products to be crimped in each head are listed in the instructions covering the head.
4.2. Crimping Dies
Each crimping head, except as noted in the preceding paragraph, uses interchangeable crimping dies designed
for that particular head. The instructions packaged with the dies give complete information.
4.3. Latch Pin Kit
Latch pin kits are available as accessories for the crimping heads as listed and shown in Figure 8. This kit was
designed to eliminate the possibility of misplacing the standard latch pin furnished with the head.
4.4. Hose Assemblies
Hoses are sold separately as accessories and are available in different lengths, which are listed with the part
numbers in Figure 8.
