Inspect all 13 of the holes closely. The service life of the tube is reduced if any of the bushings around the holes show signs of pitting or other corrosion damage. Tell your mechanic. 3. Check each of the 10 rear evacuator orice bushings for clearance. The three forward metering holes dont have to be inspected. Two M284 bushing inspection tools are included with every repaired gun tube. Place one of the tools on the gun tube following the instructions printed on the tool. Make sure the measurement end of the tool hangs over the hole. There should be a gap between the bottom of the tool and the top of the bushing. Tell your mechanic if the tool touches any of the 10 bushings. 4. Check out WP 0151-27 of TM 9-2350-314-10-2 for instructions on how to clean and lube the gun tube. 5. Use a gloved nger to apply GAA, NSN 9150-01-197-7690, to the head of all 13 bushings. Use enough pressure to force grease into the surrounding chamber area and under the head of the bushing. 6. Make sure each of the 13 holes is completely clear of grease before reassembling the bore evacuator. The bore evacuator may not work properly if anys left behind. Get rid of all grease, carbon and corrosion so that you can clearly see the gun tube.

Well, not quite. You still need to do a few things to prevent future corrosion: Check drain holes regularly. Keep them clear of dirt and debris so water drains properly. Invert or tilt buckets on construction equipment to prevent water buildup. The same goes for dump truck beds. Stop rain water from entering vehicles and equipment by closing doors and hatches. Keep moisture out of commo equipment, engine and transmission housings, and other types of closed components. The best way to prevent water damage is with a tarp or parking under cover whenever possible. if these techniques fail, be sure to remove standing water from crew areas and closed compartments. Use towels, forced air, or a vacuum or pump. Corrosion There. All done. No corrosions gonna get my truck! use tarps to keEp oUt moisture.

Regardless, you should always wear chemical-protective goggles, a respirator and chemical-resistant gloves when applying the CPC to avoid respiratory and skin irritations. CPC s can be flammable! CPAC for CPC: Whats with the Acronyms?! This is the stuff you wipe or spray on rust and corrosion-prone surfaces like bare metals that are exposed when paint or coatings are damaged. You can also use it on metal surfaces inside vehicles or on equipment. Dont be sloppy when applying CPC. But if a little splashes on surrounding surfaces, dont worry. it wont harm plastics, rubber, glass or wiring. in the world of corrosion prevention, CPC also stands for something youre gonna need now and forever: corrosion Preventive compound also known asrust inhibitor. in the world of Army acronyms, CPAC is one you gotta know now and forever. it stands for corrosion Prevention andcontrol.

14 PS 784 MAR 18 15 PS 784 MAR 18 ouve heard the joke about how many mechanics it takes to change a light bulb. All joking aside, the bulb may require more time and effort than it should if youre not using silicone grease. Replacing light bulbs in a HMMWVs side marker light is fairly easy. Remove two screws, take off the door and lens, pop out the old bulb and stick in a new one. The task gets a little dicey however, when rust builds up in the socket. It practically welds the bulb in place, making it impossible to get the bulb out without breaking it. Avoid this problem by applying a light coat of silicone grease, NSN 6850-00-9635402, on the base of the new bulb before inserting it into the socket. The silicone stops the corrosion and makes it much easier to remove the bulb. No joke, this stuff really works! Of course, if the marker light assembly is already rusted, youll need to either clean or replace it before putting in a new bulb. Dear Half-Mast, Our unit rec ently hosted a reunion, and a bunch of retirees came to visit. Some of them told me they used grease to coat the terminals on lead-acid batteries. They said it helped prevent corrosion and made the clamps easier to remove. Is this good advice? If so, what kind of grease is approved? SGT T.B.S.

Corrosion kills tactical vehicle batteries Step 2: Give both battery posts a light coat of silicone compound. Let the silicone run down around the battery post and terminal to completely seal out moisture. A 3-oz tube comes with NSN 8040-01-3317 133 and 1-pint with NSN 8040-01-3317 134. Step 1: install a felt insulator washer over the battery post. The washers are treated to help stop corrosion. Thats why they do a good job protecting one of the critical spots on a battery where corrosion often starts. Order a package of 100 with NSN 59 7 0-01-101-414 7 Step 3: install rubber covers on the battery terminals. These keep moisture off the terminals and slow the spread of corrosion. They also prevent accidental arcing from tools or other objects misplaced near the terminals. Order a single cover with NSN 2530-01-089-4992 or a package of 10 with NSN 5940-007 38-62 7 2. A hole in one end of the cover slides over the terminal and folds over the cable connector.

18 PS 784 MAR 18 19 PS 784 MAR 18 Call your mechanic to have it checked out. if theyre clogged with black soot, a rusted exhaust pipe is the likely source. Operators, after the days run, make sure you park your vehicle with the front loader bucket resting on the ground. That not only saves the hydraulics, but also allows any water to drain out. As an added step, place a piece of wood under the edge to keep the teeth from sticking to muddy ground. For backhoe buckets, make sure theyre stowed so water can drain out. Youll also want to make sure the buckets drain holes are open for the same reason. Water that sits in a metal bucket is rust waiting to start. And if that water freezes, it can crack the bucket at its weld seams. Over time, condensation can build and rust the area right next to the weld. in some cases, the metal rusts away completely, creating open cracks that allow exhaust into the engine compartment. Another way to find this problem is when you pull the air cleaner filter elements to check for buildup. That exhaust is then sucked right into the nearby air cleaner/filter assembly. Eventually, the air filter clogs up, resulting in severe engine performance issues.

Its a dirty job youll have to get down on your hands and knees and crawl to spray this area with a high-pressure hose. But its necessary to clean out the sand, rocks and hard-packed dirt under the cab where the vehicles articulation rods are located. This area gets packed with snow and ice during the winter and mud the rest of the year. Eventually, it corrodes the articulation rods and they stop moving. While youre there, take a close look at the rods for any damage or bends. The rods can break when the grader traverses over boulders, logs, tree stumps and other obstacles. A bent or busted rod means you cant articulate the graders blade. Notify maintenance if you see a damaged rod. Youll know somethings up if the warning buzzer goes off inside the cab and you cant articulate the blade. 120M Road Grader Articulation Rods Need S c r u b b i n The Corrosion Menace Turn in Your Unserviceable Aircraft Parts Cleaning is the First Step for Fighting Corrosion Got Utility Helicopter Safety Questions?

if its below -10F, use only LAW on most weapons. When the temperature drops below 10F, you can use LAW (lubricating oil, arctic, weapons). 37 36 PS 784 MAR 18 MAR 18 RBC (rifle bore cleaner) is not a lubricant. its strictly for cleaning out carbon and powder from the chamber and bore. Remember, when youve finished using RBC, you need to lube your weapon. clp (cleaner, lubricant, preservative) is usually the best choice for taking care of your weapon since it cleans, lubes and preserves in one step. lsa (lubricant, semifluid, automatic weapons) and lsa-T (lubricant, semifluid, automatic weapons with Teflon) are strictly lubricants. So, before using them you must first clean your weapons with dry cleaning solvent,MIL-PRF-680Type II. Always de-grease thoroughly when changing lubes. For theM3 recoiless rifle, use only CLP regardless of the temperature. On the M231 firing port weapon,dont use CLP. Use only LSA in normal conditions and LAW in extreme cold. For the MK 19, never use CLPits not strong enough. usegmd (grease, molybdenum disulfide) if you can get it. if you cant use LSA or LSA-T if the temperature drops below 0 F, its OK to use LAW Small Arms Small arms lubricants differ in viscosity (how easily they flow), chemical composition and heat resistance. CLP and LSA can be used on most weapons as long as the temperature is -10F or higher. These characteristics dictate which lubricant to use depending on the weapon and environmental conditions What is the best lube to use on your rifle, machine gun or pistol? There are choices but sometimes its difficult to know whats the best choice. Heres Your -10 TM is always the best guide to cleaning and lubing your weapons, but here are some general guidelines on lubricants When youre lubing, remember a light lube means a film barely visible to the eye. A heavy lube means a film thick enough to spread with your finger. There are exceptions, though Your Guide 23 PS 671 OCT 08 Dear Sergeant G.H., Certainly.

The whole top of the receiver can blow up in your face. Thats why itscriticalyou check that the bore isclearany time before firing whether youre in the field or at the range. Bullet that hits obstruction in barrel can blow up receiver! At the range, its better to check with a clearing rod rather than a cleaning rod. A cleaning rod can unscrew and come apart in the barrel. if you dont notice, the barrel blows up when you fire. Make a clearing rod with a 36-in long, 3/16-in diameterbrass welding rod, NSN 3439-00-244-4541. Put a 90-degree bend three inches from one end to make a handle. File off any burrs or sharp edges. Easy does it inserting the clearing rod so that you dont damage the muzzle crown. Dont slam the rod into the bolt face, either. if you find a stuck round, dont try to remove it with the rod. Tell your small arms repairman. its their job to remove the stuck round following the procedure in the M16/M4 -10 TM. Clear Clear Clearing Rod Of course, in the field you will have to use a cleaning rod to check for obstructions. in that case, use a swab holder section at the end of the rod you push in the barrel. if an obstruction is found in the bore, a Malfunction/Accident/Incident Report (MAIR) should be submitted by the local TACOM LAR When you pull out the rod, check for the swab holder. That way you know part of the rod isnt still in the barrel.

42 PS 784 MAR 18 U nits are better off never using cleaning tanks for their weapons, mainly because its too easy to mix up bolts when many weapons are run through the tanks. If a bolt But cleaning tanks are a fact of life at many installations, so remember these dos and donts: There are two nevers on cleaning tanks: Never use an ultrasonic cleaning system. It can completely remove a weapons protective coating, which leaves the weapon defenseless against corrosion. And never also lead to corrosion. Dont clean small arms in the same cleaning tank you use for things like vehicle parts. They may have contaminants that could damage weapons. Do protect yourself from solvent. Its strong stuff. Wear goggles, rubber gloves and coveralls with the sleeves rolled down. Do remember that some weapon parts should never be dunked in solvent. Examples are the M2 and M48 machine gun back plates, the MK 19 bolt assembly and anything plastic. Solvent will eat up these parts. Check the operator TMs for info on what parts to keep away from solvent. Do use a metal basket in the tank to ensure no parts disappear during cleaning. Do wipe clean and thoroughly dry all weapons that come out of the tank. But heres the important part: Solvent removes every bit of lubrication from weapons. If weapons are stored without being re-lubed, they will be ruined by corrosion. Do use only dry cleaning solvent Type II (81349), MIL-PRF-680. This is the only solvent authorized for small arms. Heres what the NSNs bring: Dear Editor, As part of Ft Hoods Command Maintenance Ev aluation and Training Team (COMET), we find units are unsure what to do with CBRN items like masks and JSLIST that they no longer need.

Inside are the PDISE, its cables, accessories and TM. An Army investigation determined that new PDISEs, stored in shipping crates that were exposed to weather, showed corrosion on the connectors and mounting hardware when unpacked. Further detective work revealed that the shipping crates were manufactured using formaldehyde. Formaldehyde speeds up corrosion. It causes cadmium bloom. Bloom occurs when cadmium transforms into cadmium oxide, a powder-like residue that forms on cadmium-plated components.

54 PS 784 MAR 18 55 PS 784 Store items with similar handling requirements together whenever possible. That makes it easier to issue those items and keeps them in good condition. Pack stocks that are needed most often within easy reach inside the container. Pay close attention to the number of items packed, as well as their size and weight. Youll need to account for the weight of the shipping container and the lift capacity of the vehicle used to move them, too. HAZMAT, sensitive and shelf-life items add their own challenges. Theyre usually stored together by type, but make sure those items are compatible.

Keep unit packaging in place. That layer of protection guards against deterioration and damage. If you nd an item with an open package, check it rst, then reseal it as best you can. However, if the item is electrostatic discharge sensitive (ESDS), compromised packaging that exposes the asset may have already resulted in the item being unserviceable. For these ESDS items, the packaging should still be resealed, but the items should be downgraded to batch code f and retested before issue. To prevent corrosion, containerized items will need additional inspections. At a minimum, conduct routine COSIS visual inspections on containerized items stored indoors on an annual basis. Containerized items stored outside need to be inspected on a monthly basis. Routine visual inspections are especially critical when items are stored outside. COSIS inspections are easy and, for example, can be accomplished when inspecting re extinguishers. Temperature-sensitive items shouldnt be stored in ISO containers. These items wont last in the extreme hot and cold temperatures inside containerized ASL vans. 57 PS 784 MAR 18 Dear Editor, Here at the Defense Logistics Agency (DLA), weve noticed that units are ordering 02 parts for Not Mission Capable-Supply (NMCS) equipment without annotating the Required Delivery Date (R) as N01 or 999 in GC-Army. This causes backlogs in the system because an R thats left blank is automatically filled with the Julian date. The system thinks that the part is not a priority and ships it later or on a slower mode of transportation. That can really slow things down if a unit needs the part urgently. CW3 Donald Sherman DLA Land and Maritime Editors note: Thanks for the tip! Units, dont forget to properly annotate your RDD to avoid delays. Once youve completed these steps and used the determination of storage space requirements (DOSSR) procedures, youre ready for planograph development. Planographs are drawings that tell you where in the container to stack certain items. LOGSA PSCCs Storage and Distribution Analysis Team can create planographs in a number of formats, including CAD and Microsoft Excel. A similar process is available to brigade combat teams(BCTs) with common ASLs. COSIS Care of supplies in storage (COSIS) ensures Army containerized ASL parts are ready for issue when and where theyre needed. it allows units to understand the true condition of their ASL items, providing an accurate assessment of readiness. That not only conserves resources, but provides sufficient time to fix problems when theyre discovered.

58 PS 784 MAR 18 No single contact preservative is right for every piece of equipment, so youll have to choose carefully when deciding which one to use. Some preservatives are permanent. Paint, rubber coatings and porcelain fall into this category. Dipping: This is the preferred method of applying contact preservatives because its the easiest and offers total coverage of the item. Stir the preservative frequently to prevent air bubbles from forming. After the coating dries, place the item on a piece of greaseproof barrier plastic. Flowcoating: Use owcoating for interior surfaces. Pour preservative into a tube, allow the preservative to coat the surface and drain excess preservative from the tube back into the tank. Pour the preservative into the part and rotate, agitate and slant the object as needed to coat all interior surfaces. After slushing, seal off all holes to prevent dust and dirt from entering the part. You can use rubber plugs to do that. Brushing: Only use this method if no other method is available. Brushing is usually only for very small portions of items. Use this method for larger items that arent easily handled. Fill the item with preservative to coat all interior surfaces. For some items you wont drain the preservative, but make sure to leave space for heat expansion. This method uses preservatives injected as a fog or a mist into gas tanks and interior engine cylinder walls. Apply the preservative to internal and external surfaces as a spray.

Check out MIL-STD-20 73-1E, Standard Practice for Military Packaging, or the appropriate technical manual, for guidance. Make sure to use proper protective equipment for the type of preservative youre using and equipment youre preserving. Temporary preservatives include lubricating oils and greases. There are several ways to apply them to the equipment youre protecting. one way to prevent corrosion is to use contact preservatives to protect parts and equipment from the environment while shipping or storing them. 784 58-59.indd All Pages 1/18/18 11:16 AM For even more tips, download Packaging The Basics at: rfntb


For any type of reversible indicators,the indicators will change from 60 61 PS 784 PS 784 MAR 18 MAR 18 Best business practice is to inspect the LLRCs on a monthly basis.
