Pneumatic Crimping Head Assembly 314991-1
408-4198
6.1. Daily Maintenance
Tyco Electronics recommends that each operator be
responsible for the following steps of daily
maintenance:
1. Remove dust, moisture, and other contaminants
with a clean, soft brush, or a lint–free cloth. Do
NOT use objects that could damage the head.
2. Make sure that all pins, rings, and other
components are in place and secure.
CAUTION ^{Do not remove the retaining pins as permanent}
damage to the tool could result.
!
3. Make certain all surfaces are protected with a
thin coat of any good SAE 20 motor oil. Do NOT oil
excessively.
4. When the crimping head is not in use, store it in
a clean, dry area.
6.2. Periodic Inspection
Regular inspections should be performed by quality
control personnel. A record of scheduled inspections
should remain with the crimping head or be supplied
to supervisory personnel responsible for the crimping
head. 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 6.3) and a crimping chamber
inspection (Paragraph 6.5).
6.3. Visual Inspection
1. Remove all lubrication and accumulated film by
immersing the crimping head in a suitable
commercial degreaser that will not affect paint or
plastic.
2. Make certain all components are in place. If
replacements are necessary, refer to Figure 8.
3. Inspect crimp area for flattened, chipped, or
broken areas. See Figure 5. Replace worn or
damaged parts.

Broken
Corner
Pitted
6.4. Lubrication
Lubricate all pins, pivot points, and bearing surfaces
with a high quality grease. Tyco Electronics
recommends the use of Molykote} grease, 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 jaw closure areas. Grease transferred from jaw
closure area onto certain terminations may affect the
electrical characteristics of an application.
6.5. Gaging the Crimping Chamber
This inspection requires the use of plug gages
conforming to the dimensions shown in Figure 6. Tyco
Electronics does not manufacture or market these
gages.
DANGER Disconnect air supply and remove crimping head
from pneumatic tool before inspecting crimping
chamber.
1. Remove oil and dirt from the bottom of the jaw
surfaces and plug gage element surfaces.
2. Close wire barrel crimping jaws until they are
bottomed, but not under pressure.
3. Remove locator from the head.
4. Align GO element with wire barrel crimping
section. Push element straight into crimping
chamber without using force. The GO element
must pass completely through the crimping
chamber as shown in Figure 7, Detail A.
5. Align the NO–GO element and try to insert it
into the crimping chamber. The element may start
entry, but it must not pass completely through the
crimping chamber.
6. Replace locator.
7. Repeat this procedure for the insulation crimping
section using a plug gage as shown in Figure 7,
Detail B.
If the crimping chamber passes the gage inspection,
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 chamber does
not conform to the plug gage conditions, contact your
local Tyco Electronics Field Representative or refer to
Section 7, REPLACEMENT AND REPAIR.
