6.4. Lubrication

Lubricate all pins, pivot points, and bearing surfaces

with a high quality grease. Tyco Electronics

recommends the use of MolykoteS 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 7. Tyco

Electronics does not manufacture or market these

gages.

Figure 7 (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 8A.

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 8B.

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.
