4.2. Lubrication

Lubricate all pins, pivot points, and bearing surfaces

with a high quality grease. Tyco Electronics

recommends the use of Molykote paste, which is a

commercially available lubricant. Lubricate according

to the following schedule:

Heads used in daily production—lubricate daily

Heads used daily (occasional)—lubricate weekly

Heads used weekly—lubricate monthly

Wipe excess grease from crimping head, particularly

from jaw closure areas. Grease transferred from the

jaw closure area onto certain terminations may affect

the electrical characteristics of a termination.

4.3. Periodic Inspection

1. Remove accumulated dirt, grease, and foreign

matter by immersing the head in a suitable

commercial degreaser that will not affect paint or

plastic material.

2. Inspect crimping area for worn, cracked, or

broken surfaces. If damage is evident, return the

head to Tyco Electronics for evaluation and repair.

See Section 5, REPLACEMENT AND REPAIR.

4.4. Gaging the Crimping Chamber

This inspection requires the use of a plug gage

conforming to the dimensions shown in Figure 6. Tyco

Electronics does not manufacture or market gages.

Proceed as follows:

1. Remove crimping head from tool as described in

Instruction Sheet 408–1310.

2. Remove traces of oil or dirt from the crimping

jaws and plug gage.

3. Close the jaws until they are bottomed but not

under pressure.

4. Align the GO element with the crimping

chamber. Push element straight into the crimping

chamber without using force. The GO element

must pass completely through the crimping

chamber. See Figure 7.

5. Align the NO–GO element with the crimping

chamber. Push element straight into the crimping

chamber. The NO–GO element may start entry,

but must NOT pass completely through the

crimping chamber. See Figure 7.

If crimping chamber conforms to the gage inspection,

the head is considered dimensionally correct. If

correct, the head should be lubricated with a thin coat

of any good SAE 20 motor oil and returned to service.

If not correct, the head must be returned to Tyco

Electronics for further evaluation and repair. Refer to

Section 5, REPLACEMENT AND REPAIR.

For additional information on the use of a plug gage,

refer to Instruction Sheet 408–7424.
