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 10.
3. Check all bearing surfaces for wear. Replace
worn parts.
4. Inspect crimp area for flattened, chipped, or
broken areas. Replace worn or damaged parts.
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 8. Tyco
Electronics does not manufacture or market these
gages.

Figure 8 (end)
Disconnect the battery and remove crimping
head from tool before inspecting crimping
chambers.
1. Remove oil and dirt from the jaw bottoming
surfaces and plug gage element surfaces.
2. Close wire barrel crimping jaws until they are
bottomed, but not under pressure.
3. 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 chamber as
shown in Figure 9.
4. Align the NO--GO element and try to insert it
into the chamber. The element may start entry, but
it must not pass completely through the crimping
chamber.
5. Repeat this procedure for the insulation crimping
section using a plug gage as shown in Figure 8.
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.
For additional information about the use of a plug
gage, see Instruction Sheet 408--7424.
