2-26. GENERAL ASSEMBLY INSTRUCTIONS (CONT).

Use sealing compound sparingly and only on male threads. Do not apply compound on first

two threads to avoid contamination of system from compound. Do not apply compound to

hose connections or fittings with preformed packings. Damage to equipment may result.

c. Pipe Joints and Fittings. Use sealing compound sealant or adhesive as indicated in each maintenance task.

Refer to Para 2-27 for tightening procedure.

d. 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 gage 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.

e. 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.

f. 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 bearings.

On 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

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

set. 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 of

gasket with sealant to provide added sealing.

a. Preparation. When unpacking items, remove all packing material, barrier paper, tape, plastic bags, protective

caps, and protective grease coatings. Handle and store removed components carefully.

Use sealing compound sparingly and only on male threads. Do not apply compound on first

two threads to avoid contamination of system from compound. Do not apply compound to

hose connections or fittings with preformed packings. Damage to equipment may result.

Sealing Compounds. Use sealing compounds as required in each maintenance task.
