f. To prevent moisture and foreign matter from entering open housings, lines, and other openings, use protective
coverings as soon as possible after disassembly. Wrap all parts in clean paper or dip parts in preservative oil (item 27,
Appendix E) or equivalent.
g. Remove parts only if repair or replacement is required. Do not disassemble a component any further than
necessary to accomplish needed repairs.
Instructions for preparation of material to paint, how to paint and material to be used are in TM 43-0139. Instruction for
camouflage painting are contained in FM 5-20. Stenciling and marking military vehicles are listed in TB 43-0209. Data
plate location and description is listed in Chapter 2.
Refer to Chapter 3 for lubrication procedures and requirements for the sweeper. The instructions include types and
grades of lubricant used, lube points, locations, and frequency of the required lubrication.
a. Remove protective grease coatings from new parts before installation.
b. To replace O-rings, first clean groove, then stretch ring into position. A light coating of fluid, which the ring will
operate in, will make assembly easier.
c. Coat oil seals evenly with oil (item 25, Appendix E) or grease (item 22, 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
gauge 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.
d. 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 36, 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 4-4
and 4-5 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.
