1. INTRODUCTION
3. HEAD INSTALLATION AND REMOVAL
3.1. Installation
The 626 Pneumatic Crimping Head, 1490191-1, is
designed to crimp wire ferrules on solid or stranded
copper wire. The crimping head is used with 626
Pneumatic Tooling Assemblies. Figure 1 shows the
tool holder assembly, and lists the power units for the
crimping head.
Crimping heads are coated with a preservative to
NOTE
prevent rust and corrosion. Wipe any excess
preservative from the head, particularly from the
crimping surfaces.
i
To avoid personal injury, ALWAYS disconnect tool
from air supply before installing crimping head.
DANGER
This instruction sheet provides recommended
procedures for crimp head installation, crimping, and
maintenance and inspection. For information
concerning tool setup and operation, refer to the
customer manual packaged with the appropriate tool.
STOP
Do NOT operate pneumatic tool without proper
crimping head installed; make sure that the quick
pins are FULLY tightened to avoid personal injury
and damage to the tool.
DANGER
Read these instructions thoroughly before proceeding

2. Insert crimping head into tool holder as shown in
Figure 1.
2. DESCRIPTION
3. After crimping head is properly aligned, insert and
tighten the quick pins provided with the tool holder
assembly.
The pneumatic crimping head consists of integral jaws
which close in an arc-like motion. After an operator
locates the ferrule between the crimping jaws and
inserts the stripped wire, the tool is activated to crimp
the ferrule to the wire.

1. Strip wire to required length. DO NOT nick the
wire strand or use wires with nicked or missing
conductor strands.
5. MAINTENANCE AND INSPECTION
To avoid personal injury, disconnect tool from air
supply before performing any maintenance,
inspection, or repairs.

2. Open crimping jaws by squeezing the rollers
together simultaneously; then place the ferrule into
the center of the appropriate chamber, as shown in
Figure 2. Use the correct crimp chamber for the
specific wire size.
STOP
It is recommended that a maintenance and inspection
program be performed periodically to ensure
dependable and uniform terminations. Heads should
be inspected once a month. Frequency of inspection
should be adjusted to suit your requirements through
experience and depends on:
Center Ferrule
In Dies
1. The care, amount of use, and handling of
the head.
2. The type and size of the products crimped.
3. The degree of operator skill.
4. The presence of abnormal amounts of dust
and dirt.
5. Your own established standards.
Each crimping head is thoroughly inspected before
packaging. Since there is the possibility of crimping
head damage in shipment, new crimping heads should
be inspected immediately upon arrival at your facility.
Figure 2
3. After ferrule is properly positioned, release the
rollers to allow the jaws to spring shut, holding the
ferrule in place.
5.1. Daily Maintenance
It is recommended that each operator be responsible
for the following steps of daily maintenance:

5.5. Gaging the Crimping Chamber
2. Make sure pins, rings, and other components are
in place and secure.
This inspection requires the use of plug gages
conforming to the dimensions shown in Figure 4. TE
does not manufacture or market these gages.
Make sure quick pins, are in place and FULLY

5.2. Periodic Inspection
Jaw Closure
Configuration
Regular inspections should be performed by quality
control personnel. A record of scheduled inspections
should remain with the crimping heads or be supplied
to supervisory personnel responsible for the crimping
heads. Though recommendations call for at least one
inspection a month, the frequency should be based on
amount of use, working conditions, operator training
and skill, and your established company policies.
These inspections should include a visual inspection
(Paragraph 5.3 and a crimping chamber inspection
(Paragraph 5.5).

Figure 4
1. Remove all lubrication and accumulated film by
immersing the crimping head in a suitable
commercial degreaser that will not affect paint
or plastic.
To avoid personal injury, disconnect air supply and
remove crimping head from tool before inspection
the crimping chambers.
DANGER
STOP
2. Make certain all components are in place. If
replacements are necessary, refer to Figure 6.
1. Remove oil and dirt from the bottom of the jaw
surfaces, and plug gage element surfaces.
3. Check all bearing surfaces for wear. Make sure
the rollers turn freely with minimal resistance.
Replace any worn parts.
2. Close the crimping jaws until they are bottomed,
but not under pressure.
3. Align the GO element with the crimping chamber.
Push the GO element straight into the crimping
chamber without using force. The GO element must
pass completely through the crimping chamber. See
Figure 5.
4. Inspect the crimp area for flattened, chipped, or
broken areas. Although the crimping chambers may
gage within permissible limits, worn or damaged die
closure surfaces are objectionable and will affect
the quality of the crimp.
4. Align the NO-GO element with the crimping
chamber, and try to insert it straight into the
crimping chamber. The NO-GO element may start
entry but must not pass completely through the
chamber.
5.4. Lubrication
Lubricate all pins, pivot points, and bearing surfaces
with a high quality grease. TE recommends the use of
Molykote paste, which is a commercially available
lubricant. Lubricate according to the following
schedule:
— Head used in daily production - lubricate daily
— Head used daily (occasional) - lubricate weekly
— Head used weekly - lubricate monthly
Wipe excess grease from crimping head, particularly
from die closure areas. Grease transferred from the

If the jaw closure meets the plug gage conditions, the
crimping head is considered dimensionally correct and
should be lubricated with a THIN coat of any good
SAE 20 motor oil. If the crimping chambers do not
conform to the plug gage conditions, contact your local
TE Field Service Engineer, or refer to Section 6,
