4. ASSEMBLY CONSIDERATIONS
Tool Mounting
Plate
Stuffer
The orientation of the receptacles on the wire must be
considered before termination.
4.1. Standard Method
Upper Tool
Mount
The standard method of termination is from Position 1
to the last position termination.
Figure 3
4.2. Alternate Method
The fixtures listed are used to terminate the
wire/cable types listed in Figure 2.
The alternate method of termination is from Position 1
to the Position 1 termination. Note that this method of
termination necessitates a second wire/cable cut.
Refer to Figure 4.
The ribbon cable fixture features a ribbon cable
clamp, and a removable cable stop to allow closed
end, or feed--thru terminations.
5. SETUP PROCEDURE
The upper tooling fixture is shown in Figure 3.
1. Install the upper tooling assembly onto the ram
as shown in Figure 5.
3. CABLE REQUIREMENTS
2. Install the screws provided, but do not tighten
completely.
Refer to the cable requirements below.

NOTE
i
The polarization legs of the connector must
engage with the connector locator. The connector
locator should engage with the and return to a
vertical position.
Ensure that the connector is loaded correctly
before proceeding.
CAUTION
!
If the connector is not loaded correctly, damage
to the connector will result.
2. With the connector properly loaded, install the
desired wire into the wire holding combs. Repeat
installation of wires until all wires have been
loaded.
Figure 5
3. Slide the fixture underneath upper tooling, and
rotate handle until upper tooling is fully seated.
Raise upper tooling, and slide fixture to front end
stop.
Special Setup Procedure for Discrete Wire
Select the desired wire size, and load into wire
holding comb. If the comb retains the wire proceed
with termination (Section 6). If wire comb does not
hold discrete wire, remove the comb retaining screws
and flip combs over to opposite side. Then tighten
comb retaining screws and load wire for test fit.
Install connector as described in Section 6, and pull
the handle until the upper tooling contacts the
connector housing. The upper tooling should just
touch top of connector housing. If the upper tooling
damages the connector, adjust the ram stop collar to
limit the stroke of the arbor frame terminator.
4. Remove the wires from the combs being careful
not to disturb contacts.
5. Depress the handle on connector locator and
carefully remove terminated connector from the
fixture by lifting straight ”up.”
CAUTION
!
Do not twist the terminated connector during
unloading, or damage may result.

Connector
For closed--end ribbon cable applications, it is
important that the cable is cut square. Refer to
product application specification 114--13072.
For feed--through ribbon cable terminations, be
sure to remove the cable stop.

1. Depress the ribbon cable locating plate mounted
on the connector locator, and install connector as
shown in Figure 6.
NOTE
i
The polarization legs of connector must engage
with connector locator. The connector locator
should engage with connector and return to a
vertical position.
Ensure that connector is loaded correctly before
proceeding.
CAUTION
!
If the connector is not loaded correctly, damage
to connector will result.
2. With connector properly loaded, raise the ribbon
cable clamp and lay ribbon cable on top of the
connector and hold in place.
3. Close and latch the ribbon cable clamp.
4. Slide the fixture underneath the upper tooling,
and rotate handle until the upper tooling is fully
seated. Raise the upper tooling, and the slide
fixture to front end stop.
5. Depress the latch and raise the cable clamp.
6. Depress the ribbon cable locating plate and
carefully remove the terminated connector from the
fixture by lifting straight “up.”
CAUTION
!
Do not twist the terminated connector during
unloading, or damage may result.
7. PRODUCT INSPECTION
Inspect housing and contacts for physical damage.
Refer to product application specification 114--13072.
8. TOOLING INSPECTION AND MAINTENANCE
8.1. Inspection
It is recommended that the arbor frame assembly be
inspected immediately upon arrival at your facility
(and at regularly scheduled intervals thereafter) to
ensure that it has not been damaged during handling.
8.2. Maintenance and Lubrication
To prolong the useful life of your Arbor Frame
Assembly and MTA--50 Mass Termination Tooling,
and to provide the smoothest operation, maintain and
lubricate monthly as follows:
NOTE
i
Though recommendations call for lubrication at
least once a month, the frequency should be
based on amount of use, working conditions, and
established company policies.
1. Remove the upper tooling and lower tooling.

2. Move the ram to the bottom of its stroke (the
adjustment ring should bottom on the base plate).
Note the position of the handle. Loosen the handle
adjustment knob sufficiently for the handle to slide
from its mounting hole. Remove the handle.
3. Using a small flat--blade screwdriver, turn the
spring plunger counterclockwise until it no longer
contacts the ram.
4. Grip the adjustment ring, and pull it upward,
then remove the ram.
5. Apply ANDEROL 757® grease, or equivalent, to
the gear teeth on the ram and to the bore of the
frame.
6. Re--assemble the ram into the bore with the
grooved side of the ram aligned with the spring
plunger. Ensure that the gear teeth in the ram
engage the teeth of the pinion (small diameter gear
in bore of frame) so that the handle position will be
the same as noted in Step 2 when the adjustment
ring bottoms.
7. Turn the spring plunger clockwise until it
bottoms lightly on the ram, then back off one--half
of a turn.
8. Re--assemble the handle and upper tooling and
lower tooling. Ensure proper alignment of tooling
before operating the arbor frame assembly.
9. Remove any excess grease from the outer
surface of the frame and adjustment ring with a
soft cloth.
9. REPLACEMENT AND REPAIR
A complete inventory of customer--replaceable parts
should be stocked and controlled to prevent lost time
when replacement of parts is necessary. Other parts
should be replaced by TE Connectivity to ensure
quality and reliability. Order replacement parts
through your representative, or call 1--800--526--5142,
or send a facsimile of your purchase order to
