5-22. ASSEMBLY (CONT).
Coat oil seals evenly with oil (item 16, appendix E) or grease (item 14, appendix E) before installing. Install
oil seals with seal lip facing in, applying an even force to the outer edge of seal. If oil seals are to be installed over keyed
or splined shafts, use a guide to prevent sharp edges of the keyway or spline from cutting the seal. Guides can be very
thin gage sheet metal shaped to the required diameter. Make certain guide edges are not sharp and are bent slightly
inward so they do not cut the seal.
Lubricate bearings before reassembly with the type of lubricant normally used in the related housing or
container. This will provide lubrication during the run-in until lubricant from the system can reach the bearings.
Put hoses, tubes, lines, and electrical wiring in place by matching identification tags, markings on equipment, and using
illustrations presented. Replace cable ties (item 24, appendix E) as necessary. Use sealing compounds as required in
each maintenance task. When installing screws and nuts, be sure to tighten to torque values given. Refer to tables 5-2
and 5-3 for standard and metric torque values. All torques listed are dry torques.
Make changes to equipment pressures, settings, and positions only as required in each maintenance task. Adjustments
will bring the equipment into proper operating conditions.
