TM 5-3825-225-14&PSection V. GENERAL MAINTENANCE INSTRUCTIONS4-7.GENERAL.This section contains general maintenance instructions for unit maintenance personnel. These instructions coverremoval, cleaning, inspection, repair, and installation procedures to be followed when maintaining the water distributor.4-8.REMOVAL PROCEDURES.a.Disconnect the battery ground cable before removing electrical parts.b.Prior to removal, clean the area around air or fuel line fittings to prevent dirt from entering into ports as thefitting is removed. Cover or plug all open ports or lines.c.Attach identifying tags to the mating ends of electrical, air, and fuel lines asthey are disconnected.d.Use proper lifting devices when removing heavier components. Ensure that these devices are correctlyarranged and attached before removing attaching hardware.4-9.CLEANING PROCEDURES.WARNINGDry cleaning solvent P-D-680 Is toxic and flammable. Always wear protectivegoggles and gloves, and use only in a well-ventilated area. Avoid contact withskin, eyes, and clothes, and DO NOT breathe vapors. DO NOT use near openflame or excessive heat. The solvent's flash point is 100°F-130°F (38°C -59°C). Ifyou become dizzy while using cleaning solvent, Immediately get fresh air andmedical help. If solvent contacts eyes, immediately wash your eyes and getmedical aid.a.Do not spray or soak electrical parts such as coils, junction blocks, switches, and insulated wires in cleaningsolutions. Use a clean, lint-free cloth moistened with dry cleaning solvent (Item 7, Appendix D).b.Use a cleaning compound to clean external parts and components.CAUTIONDo not expose preformed packing, gaskets or other rubber materials to cleaningsolvents. The solvents will destroy them.c.Use dry cleaning solvent (Item 7, Appendix D) to clean bearings and internal engine parts. If necessary,brush caked grease and dirt from parts. Be careful not to score or damage facing parts. Spin bearings inlight lubricating oil after cleaning to remove solvent.4-10. INSPECTION PROCEDURES.a. Check all hose surfaces for broken or frayed fabric. Check for breaks caused by sharp kinks or rubbingagainst other parts of the water distributor.b.Inspect metal tubing lines for kinks.c.Inspect fitting threads for damage.d.Visually inspect all castings and weldments for cracks.e.Inspect all wires for chafed or burned insulation. Inspect all terminal connections for loose connections andbroken parts.f.Inspect all bearings and bearing cups in accordance with TM 9-214.4-11. REPAIR PROCEDURES.a.Replace all broken, frayed, crimped or soft flexible lines and hoses. Replace fittings that are stripped ordamaged. Ensure that hose clamps do not crimp hoses.b.Replace all broken, worn, burned, or chafed electrical wiring. Wires with several broken strands must bereplaced. Broken strands increase the resistance of the wire and affect the efficiency of the electricalcomponents.c.Replace any bolt, screw, nut, or fitting with damaged threads. Inspect tapped holes for thread damage. Ifcross threading or spalling is evident, drill and tap the hole for an oversize screw or stud. When retapping willresult in weakening the part, or when the cost of the part makes retapping impractical, replace the damagedpart. At times, merely chasing the threads with the proper size tap or die will be adequate.4-13
