TM 9-2320-360-34-1
2-11. GENERAL REPAIR INSTRUCTIONS (CONT)
g.
Fasteners. Replace any bolt, screw, nut, or fitting with damaged threads. Inspect tapped holes for thread
damage.
h.
Dents. Straighten minor body dents by tapping with a soft-faced hammer while using a wooden block for
backing.
i.
Sheet Metal Repair. Repair minor sheet metal cracks by installing patches.
2-12. GENERAL ASSEMBLY INSTRUCTIONS
a.
Preparation. Remove protective coating from new parts before installation.
b.
Preformed Packing Installation. Lubricate all preformed packings with a thin coating of light mineral oil before
installation. Uniformly press the preformed packing into position.
c.
Pipe Joints
WARNING
Pipe thread sealing compound can burn easily, can give off harmful vapors, and is
harmful to skin and clothing. To avoid injury or death, keep away from open fire
and use in well-ventilated area. If pipe thread sealing compound gets on skin or
clothing, wash immediately with soap and water.
CAUTION
Use pipe thread sealing compound sparingly only on pipe threads. Do not apply
compound to hose connections. Failure to comply may result in component
failure.
Use nonhardening pipe-joint compound when joining piping.
d.
Gaskets. Remove all traces of previous gasket and sealant before installing new gasket.
e.
Silicone Sealant
WARNING
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.
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. Excess silicone sealant should be wiped off after assembling the mating parts.
f.
Oil Seals. Install oil seals with seal lip facing towards lubricant, applying an even force to outer edge of seal.
Coat oil seals evenly with grease before installing. If oil seals will be installed over keyed or splined shafts, use a guide.
This will prevent sharp edge of keyway or splines from cutting the seal. Construct guides of very thin gage sheet metal
and shape to required diameter. However, ensure guide edges are not sharp. Bend them slightly inward so they do not
cut the seal.
g.
Seal Rings. Coat seal rings with oil and carefully install into their bores. If seal rings must be installed over
threaded parts, temporarily wrap the threads with tape to protect the seal ring.
h.
Bearings and Shafts. During assembly of shafts and bearings in housings, first mount bearing on shaft. Then
install the assembly by applying force to shaft. When mounting bearings on shafts, always apply force to the inner races
of the bearing.
i.
Bearing Lubrication. Lubricate bearings before reassembly with the type of lubricant normally used in the
related housing or container. This will provide lubrication during the first run-in until lubricant from system can reach the
bearings.
