TM 9-2320-363-34-12.3.4.5.6.7.8.9.Packing Installation. Lubricate ail packings with a thin coating of light mineral oil beforeinstallation. Slightly stretch packing and place into position. Rotate component on flat surfaceor uniformly press the packing into position.Pipe Joints. Use nonhardening pipe-joint compound or thread sealing tape when joining piping.Gaskets. To provide added sealing for gasket, coat both sides with sealant. Remove all tracesof previous gasket and sealant before installing new gasket.Silicone Sealant.W A R N I N GOn direct contact, uncured silicone sealant irritates eyes. In case of contact,flush eyes with water and seek medical attention. Avoid prolonged contactwith skin.Silicone sealant is often used instead of a gasket to seal mating parts. Mating parts must beclean, dry, and free of oil or grease for proper adhesion. After silicone sealant has beenapplied, mating parts must be assembled within 15 minutes. Silicone sealant starts to set upin 15 minutes and takes 24 hours to completely cure. Excess silicone sealant should bewiped off after assembling mating parts.Oil Seals. install oil seals with seal lip facing toward lubricant, applying an even force toouter edge of seal. Coat oil seals evenly with grease before installing. If oil seals will beinstalled over keyed or splined shafts, use a guide. This will prevent sharp edge of keyway orsplines from cutting the leather or neoprene seal. Construct guides of very thin-gage sheetmetal and shape to required diameter. However, make certain guide edges are not sharp.Bend them sightly inward so they do not cut the seal.Seal Rings. Coat seal rings with oil and carefully install into their bores. If seal rings must beinstalled over threaded parts, temporarily wrap the threads with tape to protect the seal ring;then remove the tape.Bearings and Shafts. During assembly of shafts and bearings in housings, first mount bearingon shaft, then install the assembly by applying force to shaft. When mounting bearings onshafts, always apply force to the inner races of the bearing.Bearing Lubrication. Lubricate bearings before reassembly with the type of lubricant normallyused in the related housing or container. This will provide lubrication during the first run-inuntil lubricant from the system can reach the bearings.1. Preparation. Before installing any parts, make sure they are clean and that both mountingsurfaces are clean and free of oil and grease (unless otherwise noted).2. installation. Make sure there is enough clearance to install part. Disassemble adjacent partsas needed to provide working clearance.2-35
