2. DESCRIPTION
Figure 2 shows the main components of the mechanical feed applicator. Figure 3 shows the main components
of the air feed applicator.
Each applicator is individually designed for specific terminals. The wire crimp height and insulation crimp height
can be adjusted to accommodate different wire sizes and insulation ranges. The applicator is also designed to
accept modular-feed packages.

The Ocean applicator can be used in various machines, provided the machine has the proper stroke length and
all the necessary equipment. Two basic applicator design styles (Atlantic and Pacific) are available to meet
many of the terminator and leadmaker configurations worldwide (Figure 5). The applicator ram and base plate
interfaces are different, but most of the Ocean applicator features and adjustments are the same.

The terminal strip must be fed into the applicator, with the wire barrels facing up and first into the applicator,
between the strip guide plates. It passes under the stock drag, and the lead terminal is positioned over the anvil
(for pre-feed applicators) or one terminal length from the anvil (for post-feed applicators). The feed pawl feeds
one terminal during each cycle of the machine. The ram post (also referred to as the ram mounting post)
engages the post adapter of the machine ram, which actuates the applicator.
The wire crimp disc is located just below the ram post interface. The wire crimp disc is designed with a spring-
loaded adjustment mechanism for precise crimp height adjustment increments of 0.01 mm [.0004 in.] and a
total adjustment range of 1.50 mm [.059 in.]. By rotating the wire crimp disc, the ram interface raises and
lowers relative to the applicator housing. The indicator notch of the ram points to the numbers on the perimeter
of the wire crimp disc, indicating a relative crimp height. For proper crimp height, the number on the wire crimp
disc must correspond to the number on the applicator identification tag and drawing.
The wire and insulation crimpers are held in a pre-set position by the ram and the crimper bolt. The insulation
crimper is free to move up and down so that the insulation crimp height can be adjusted by pulling the spring-
loaded insulation crimp dial out slightly and rotating it to a different number.
The slug blade, which cuts the connection tab from the strip between the lead and second terminals, is also
attached to the bottom of the ram. The spring-loaded terminal hold-down, located on the ram, holds the
terminal in place during the crimping and slugging process.
The applicator mounting surface is the base plate. The anvil, strip guide plate, and applicator housing are
mounted on the base plate. The strip guides, stock drag, front and rear shear plates, and strip hold-down plate
are all mounted on the strip guide plate. The shear plates are spaced to allow the slug blade to pass between
them, removing the connecting tab between the terminals.
2.1. Terminal lubricant
Some terminal strips require the use of a terminal lubricant to reduce tooling wear and damage to the plating on
some terminals. Wick-type lubricators apply lubricant to the terminal strip as it feeds into the applicator. Ocean
applicator lubricator assembly PN 2119955-2 is available.
Disconnect electrical power when performing maintenance or repair on this equipment.
NOTE
The question of whether a lubricant is required depends on the final use of the crimped terminal. To determine whether your
applications warrant the use of a terminal lubricant, contact your TE representative. (See section 6Error! Reference source n
ot found. for contact information.)
If your application warrants the use of a terminal lubricant, use Stoner Terminal Lubricant E807 from Stoner,
Inc. Call 800-227-5538 or visit Stoner’s Critical Cleaning website.

2.2. Applicator with mechanical feed system
With this applicator (Figure 6), the terminals are fed by the action of the feed cam and a series of rods and
levers that move the feed pawl.

Two feed cams (Figure 7) can be used with the mechanical feed applicator.
The pre-feed cam advances the lead terminal over the anvil on the upward stroke of the ram assembly
so that a terminal is over the anvil when the machine is at rest. The pre-feed set up is typically used for
side-feed bench applications.
The post-feed cam advances the lead terminal over the anvil on the downward stroke of the ram
assembly. The post-feed set up is typically used for leadmaker and end-feed bench applications.

These feed cams can be mounted in two different mounting holes, depending on machine stroke length and
feed type (Figure 8 and Figure 9). When not in use, the spare feed cam can be mounted to the applicator
housing in the spare feed cam storage location (Figure 6).

NOTE
Pacific applicators can only be used with 30-mm stroke machines. They have only the 30-mm feed cam mounting positions on
the applicator ram.
NOTE
The recommended setup for mechanical end-feed applications is post-feed. The applicator can be configured for pre-feed, but
this causes problems with some applications. Feed issues or terminal jamming can occur in the mechanical pre-feed
configuration.

2.3. Applicator with air feed system
With an air feed applicator (Figure 3), the terminals are fed by the action of an air feed module using a constant
air supply that moves the feed pawl. The speed control valves control the speed of the feed and retract strokes.
Two feed cams (Figure 10) can be used with the air feed applicator.
The supplied pre-feed feed cam advances the lead terminal over the anvil on the upward stroke of the
ram assembly, leaving a terminal over the anvil when the machine is at rest.
An optional post-feed cam (part number 2391975-1) is available. It advances the lead terminal over the
anvil on the downward stroke of the ram assembly, leaving the anvil clear when the machine is at rest.

1
Pre-feed cam
2
Post-feed cam (optional)
These feed cams can be mounted in two different mounting holes, depending on machine stroke length and
feed type (Figure 8 and Figure 9).
The air supply connection (Figure 3) must be connected to an air supply line providing continuous
pressure of 5.00 to 6.00 bars [72 to 87 psi] at the applicator.
No oil lubrication of air is required for the Ocean air feed module after receiving and use within a
production environment.
The ram collar must be installed when changing crimp tooling to prevent the ram from becoming
captured. If this occurs, the air feed assembly must be removed to release the applicator ram.
CAUTION
The air feed housing has a vertical etched line that serves as a visual aid to ensure that the piston assembly is located within
the limits of the air cylinder position (see Figure 3). The feed pawl holder must be positioned to the right of the line. Incorrect
positioning of the feed pawl can cause the air feed module to fail prematurely.

between the strip guides with the terminal wire barrel entering first and the open side of the wire barrel
facing up.
9. Raise the feed pawl and continue to feed the terminal strip until the lead terminal is over the anvil and
the feed pawl engages the terminal in the proper position.
10. If terminals are post-feed, lift the feed pawl and pull the strip back one terminal length. The lead
terminal is moved over the anvil on the downward stroke of the ram assembly. Make sure that the tip of
the feed pawl is in the feed hole of the carrier strip.
NOTE
Some carrier strips have additional holes that are not used for feed purposes.
11. Hand-cycle the machine several times to make sure the applicator is properly adjusted as described in
section 5.
12. Reinstall the applicator guard assembly.

5. ADJUSTMENTS
5.1. Adjusting the wire crimp height
1. Select an increment number from the data plate for the wire size to be used.
Values range from 0 (the largest crimp height) to 150 (the smallest).
Each increment represents a change in crimp height of 0.01 mm [.0004 in.].
2. Adjust the crimp height by turning the wire crimp height adjustment disc until the required increment
number lines up with the indicator notch on the front of the ram (Figure 12).
Turn the disc clockwise to decrease the crimp height.
Turn the disc counter-clockwise to increase the crimp height.
Figure 12: Wire crimp height adjustment disc
1

2
Indicator notch
3
Insulation crimp dial
3. Adjust the insulation crimp as described in section 5.3.
4. Make several test cycles and inspect the terminations closely. Look for rough or sharp edges around
the crimped barrels (flash), deformed crimps, bent terminals, or other defects caused by worn or
broken tooling. If necessary, replace the tooling as described in section 6.
If the terminations appear normal, measure the crimp height of each termination as described in
instruction sheet 408-7424 (packaged with the applicator). The crimp height must agree with the
measurement specified on the applicator drawing for the wire size being used. Record crimp height
dimensions for reference.
If the crimp height is incorrect, remove the applicator and install one that is known to produce
terminations of correct crimp height.
5. Make several test cycles and repeat the inspection.
If the crimp height is incorrect for this applicator, the problem is the machine shut height. Refer to
the appropriate machine manual (Table 1) for corrective measures.
If the crimp height is correct, the problem is in the original applicator. Refer to section 6.6,
Repairing the adjustable crimp height, for corrective measures.
6. During extensive operation, periodically inspect the terminals as described in step 4 to ensure that the
applicator is producing correct terminations.

5.3. Adjusting the insulation crimp
The insulation crimp is adjustable in increments of 0.19 mm [.0075 in.]. Pull the insulation crimp dial out (refer
to Figure 5) and turn it to line up with a number (1 through 18) so that it is shown at the indicator notch on the
ram.
Number 1 makes the loosest crimp.
Number 18 makes the tightest crimp.
The total range of adjustment is approximately 3.30 mm [.130 in.]. Start with number 1 and make test crimps
while increasing the setting one number at a time until the proper insulation crimp height is achieved.
NOTE
Some applicators have a special insulation adjustment dial with different range and increments. Refer to the marking on the
front of the insulation crimp dial for correct increments.
5.4. Adjusting the terminal strip feed
Mechanical feed applicator
NOTE
When adjusting a mechanical feed applicator, always start by properly adjusting the stroke length. Then adjust the fine feed
adjustment to position the terminal over the anvil.
1. With the terminal strip properly loaded, check the position of the lead terminal relative to the slug blade.
Position the feed pawl in the required location on the terminal (typically the end of the wire barrel).
Refer to Figure 6. The slug blade must remove the connecting tab between lead and second terminals
without deforming either terminal.
2. Watch the feed pawl as the machine is hand-cycled (or slowly cycled) several times. It should have
enough over-travel on the backstroke to pick up the next terminal, but not so much over-travel that the
feed pawl moves up onto the body of the terminal (see Figure 16).
If the pick-up point is the mating end of the terminal, the backstroke over-travel should be about
equal to the distance between the wire barrel and the mating end of the terminal (Figure 2).
For other types of terminals (for example, ring tongue), over-travel should be about the same,
depending on the terminal features and configurations (for example, stud hole).
Figure 16: Feed pawl backstroke over-travel
3. Check the backstroke position.
If the backstroke position is correct, the tab is correctly slugged out, and the terminals are not
damaged, the feed adjustments are complete.
If not, continue to the next step.
NOTE
Two adjustments work in combination to properly position the lead terminal over the anvil and give the proper backstroke
position to pick up the next terminal feed hole. Use one or both adjustment types to properly adjust the applicator.

408-35043
Rev D
17 of 30
4. If the slug blade does not shear the terminal in the correct position, make note of the position and
continue to cycle the applicator to check the backstroke position. If the lead terminal is not slugged out
correctly and the backstroke position is incorrect, both the stroke length and the fine feed position must
be adjusted. Stroke length (backstroke position) must be adjusted before final centering of other
terminals under the slug blade.
a. Loosen the stroke length adjustment lock screw (see Figure 6).
b. Turn the stroke length adjustment screw to adjust the stroke length.
Turn the screw counter-clockwise to reduce the stroke length.
Turn the screw clockwise to increase the stroke length.
c. Tighten the stroke length adjustment lock screw.
5. Repeat steps 1 through 4 as required until the proper stroke length is achieved.
6. If the feed pawl stroke length is satisfactory and the backstroke position is correct, but the lead terminal
is not slugged out correctly (or positioned under the slug blade correctly) and the stroke is correct, but
the position is incorrect, an adjustment to the fine feed screw is required.
a. Loosen the fine feed adjust lock screw on the side of the feed pawl holder to allow the fine feed
adjustment screw to turn. Refer to Figure 6.
CAUTION
Do not remove the fine feed adjust lock screw. A nylon plug is captured behind the lock screw. Loss of this plug causes
damage to the fine feed adjustment screw threads when the lock screw is tightened.
b. Turn the adjustment screw to position the feed pawl and place the terminal under the slug blade.
Turn the screw counter-clockwise to move the feed pawl away from the anvil.
Turn the screw clockwise to move the feed pawl toward the anvil.
c. Tighten the lock screw to secure the fine feed adjustment screw.
7. Re-check the adjustment for the proper position and stroke as described in step 1. Repeat the
adjustment procedure as necessary.

Adjusting the feed
The feed stroke (terminal pitch), terminal position, and feed speed adjustments are set at the factory. If
adjustment is necessary, follow the instructions below:
If the pick-up point is the end of the wire barrel, the backstroke over-travel (Figure 16) should
be approximately equal to the distance between the wire barrel and the mating end of the
terminal.
For other types of terminals (for example, ring tongue), over-travel should be about the same,
depending on the terminal features and configurations (for example, stud hole).
Adjusting the feed stroke
1. Remove air pressure from the air feed module.
2. Release terminal drag.
3. Install the terminal strip in the applicator until the feed pawl drops into the backstroke position
