GENERAL ASSEMBLY INSTRUCTIONS
Preparation. Remove protective grease coatings from new parts before installation.
Preformed Packing Installation. Lubricate all preformed packings with a thin coat of
lubricating oil (Item 23, WP 0176 00) before installing. To install a preformed packing, first clean
the groove, then stretch packing and place into position. Place component on flat surface and
uniformly press packing into position.
Pipe Joints and Fittings. Use nonhardening sealing compound (Item 28, WP 0176 00) or
antiseize tape (Item 34, WP 0176 00) to join piping and fittings.
Oil Seals. Coat oil seals evenly with oil or grease before installing. Install oil seals with seal lip
facing toward lubricant, applying an even force to outer edge of seal. If oil seals are to be
installed over keyed or splined shafts, use a guide to prevent sharp edge of keyway or splines
from cutting the leather or neoprene seal. Construct guides of very thin gauge sheet metal and
shape to the required diameter. Make certain guide edges are not sharp and are bent slightly
inward so they do not cut the seal.
Bearings and Shafts. When mounting bearings on shafts always apply force to the inner
races. When mounting bearings into housing always apply the force to the outer race.
Bearing Lubrication. Lubricate bearings before assembly with lubricant used in the related
housing or container to provide the first run-in until lubricant from the system can reach the
Adhesive sealant MIL-S-46163 can damage your eyes. Wear safety
goggles/glasses when using; avoid contact with eyes. If sealant contacts
eyes, flush eyes with water and get immediate medical attention. Failure to
comply may result in injury to personnel.
Silicone Sealant. Silicone sealant is often used instead of a gasket to seal mating parts. The
mating parts must be clean, dry, and free of oil or grease for proper adhesion. After silicone
sealant has been applied, the mating parts must be assembled immediately. Silicone sealant
starts to set up in 15 minutes and takes 24 hours to completely dry. Excess silicone sealant
should be wiped off after assembling the mating parts.
Gaskets. Remove all traces of previous gasket and sealant before installing new gasket. Coat
both sides of gasket with sealant to provide added sealing.
GENERAL INSTALLATION INSTRUCTIONS
Preparation. When unpacking items, remove all packing material, barrier paper, tape, plastic
bags, protective caps and protective grease coatings. Handle and store removed components
Use sealing compound sparingly and only on threads. Do not apply compound to hose
connections. Failure to comply may result in damage to equipment.
