TM 9-2320-365-34-1d. Oil Seals. Coat oil seals evenly with oil or grease before installing. Install oil seals with seal lip facing towardlubricant, 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 guidesof very thin gage sheet metal and shape to the required diameter. Make certain guide edges are not sharp and arebent slightly inward so they do not cut the seal.e. Bearings and Shafts. When mounting bearings on shafts always apply force to the inner races. Whenmounting bearings into housing always apply the force to the outer race.f. Bearing Lubrication. Lubricate bearings before assembly with lubricant used in the related housing or containerto provide the first run-in until lubricant from the system can reach the bearings.WARNINGOn direct contact, uncured silicone sealant irritates eyes. In case of contact,flush eyes with water and seek medical attention. In case of skin contact,wipe off and flush with water.g. Silicone Sealant. Silicone sealant is often used instead of a gasket to seal mating parts. The mating parts mustbe clean, dry, and free of oil or grease for proper adhesion. After silicone sealant has been applied, the matingparts must be assembled immediately. Silicone sealant starts to set-up in 15 minutes and takes 24 hours tocompletely dry. Excess silicone sealant should be wiped off after assembling the mating parts.h. Gaskets. Remove all traces of previous gasket and sealant before installing new gasket. Coat both sides ofgasket with sealant to provide added sealing.2-24. GENERAL INSTALLATION INSTRUCTIONSa. Preparation. When unpacking items, remove all packing material, barrier paper, tape, plastic bags, protectivecaps and protective grease coatings. Handle and store removed components carefully.CAUTIONUse sealing compound sparingly and only on threads. Do not apply compound tohose connections. Damage to equipment may result.b. Sealing Compounds. Use sealing compounds as required in each maintenance task.c. Torquing. Tighten bolts, screws, washers, and fittings as required in Appendix E or in each maintenance task.d. Identification Tags. Put hoses, tubes, lines, and electrical wiring in place by matching identification tags andmarkings on equipment.e. Hoses, Air Lines and Wiring. After installing hoses, air lines and wiring, ensure that they do not contactmoving parts or components edges. Secure in place, out of way with cable ties and cushion clamps.2-989
