3.16 Matched identification numbers. The C-link and coupling plates of each detachable
link assembly shall be marked (see 6.2) with matched identification numbers. The numbers on
all components of a link shall be the same in order to identify the link and ensure mating of parts.
Each link of the lot shall have a different identification number. The number shall be indented a
minimum of 0.063 inch and a maximum of 0.094 inch. The identification number shall be
stamped on the C-link and coupling plates after the coupling plates have been tightly closed on
the C-link (see 3.10). The indented numbers shall be 0.250 inch high and located in the areas
shown on figure 3. Stamping dies shall be of the round bottom, low stress type (see 4.4.5). The
identification numbers shall be assigned by the manufacturer and be traceable to production and
test inspection records.
3.17 Finish (see 6.5). The C-link and right and left hand coupling plates shall be
thoroughly cleaned by tumbling or sand blasting. After satisfactory completion of all tests and
inspections, the detachable link shall be assembled with the taper pin. Before shipment the taper
pin shall be coated with grease conforming to VV-G-632, and lightly driven into the assembled
detachable link for ease of disassembly (plug and hairpin shall not be installed). The assembled
detachable link shall then be primed with two coats of epoxy polyamide, green primer, formula
150 in accordance with MIL-DTL-24441/20 (3 mils thick each coat). The assembled detachable
link shall then be surface topcoated with two coats of silicone alkyd enamel conforming to
type II, class 2, grade A of MIL-PRF-24635 (3 mils thick dry film each coat). Surface topcoat
color shall be in accordance with FED-STD-595/27038. As an alternate topcoat, two coats of
No. 40 Vitanic black asphalt varnish (NSN 8010-00-160-5856 or 8010-00-299-0214) may be
used (3 mils thick dry film each coat). The plug bore in the C-link shall be protected to prevent
paint from contacting the bore surface (see 4.4.7 and 4.4.9).
