3.26 MISCELLANEOUS CLEANING, SEALING, AND<br />
CPC REQUIREMENTS.<br />
NOTE<br />
Do not apply thermal spray pure zinc, 85/15% zinc/<br />
aluminum or pure aluminum to stainless steel muffler<br />
components.<br />
3.26.3.1 Remove corrosion with abrasive mat, A-A-58054<br />
and MIL-PRF-680, Type II or III, CID A-A-59601 or MIL-<br />
PRF-32295, Type II, wipe off residue and allow to air dry.<br />
Solvent will cause softening and deterioration of rubber<br />
gaskets, seals, and insulation.<br />
3.26.3.2 Clean electrical contacts with MIL-PRF-29608,<br />
Type I, Electrical Contact Cleaner.<br />
3.26.3.3 Apply a thin layer of CPC, MIL-L-87177, Grade B,<br />
to the contacts.<br />
3.26.4 Internal Electrical Components: Circuit Breakers,<br />
Relays, etc. Instructions for removing and cleaning internal<br />
electrical components are as follows:<br />
Figure 3-4. Corrosion Under Data Plate<br />
3.26.1 Sealing of Addressograph or Dash-A Plates.<br />
Whenever an Addressograph or Dash-A-Plate is used in lieu<br />
of die cut vinyl markings or stencils as data plates, they should<br />
be installed wet with corrosion inhibiting sealant, MIL-PRF-<br />
81733. The requirement for wet installation also includes the<br />
fasteners used for installation. Using the sealant will prevent<br />
corrosion from occurring between the data plate and SE.<br />
3.26.2 Electrical Hardware and Terminals.<br />
Do not remove thin plating on electrical components.<br />
Always use the mildest method of corrosion removal.<br />
3.26.4.1 Remove heavy corrosion by rubbing contact surfaces<br />
with an abrasive typewriter eraser. Remove light to<br />
medium corrosion by rubbing contact surface with ruby red<br />
eraser.<br />
3.26.4.2 Clean contacts with MIL-PRF-29608, Electrical<br />
Contact Cleaner, Type 1, Class C. Clean relay or circuit<br />
breaker assembly with acid brush, A-A-289. Remove foreign<br />
matter with a soft brush.<br />
NOTE<br />
Clean corrosion on terminal studs with a wire brush<br />
or terminal stud-cleaning tool.<br />
3.26.2.1 For cables and terminal posts, brush on a light coat<br />
of petrolatum, VV-P-236 Grease.<br />
3.26.2.2 For battery frame and holder, apply one coat of<br />
primer, MIL-PRF-23377, Type I, Class 2 or MIL-DTL-53022,<br />
Type II (Lead and Chromate Free Epoxy Primer) and one coat<br />
of MIL-PRF-85285 applied to a dry film thickness of 1.6 to<br />
2.4 mils.<br />
3.26.3 Light Assemblies. Instructions for cleaning the light<br />
assemblies are as follows:<br />
• Do not apply CPC MIL-C-81309 to printed circuit<br />
boards. Contact points must be clean for CPC to<br />
function properly.<br />
• Care must be taken to avoid removing thin plating.<br />
3.26.4.3 Apply a thin coat of CPC MIL-L-87177, Grade B,<br />
to relays and contacts<br />
3.26.5 Electrical Connectors. Remove light corrosion with<br />
toothbrush, A-A-59 or A-A-123, soaked in solvent, TT-I-7<strong>35</strong>,<br />
isopropyl alcohol.<br />
