MAY 18 1 PS 786 After a few days in the field, you and dirt become real buddies. Theres dirt in your hair, on your face and under your nails. it gets ground into your uniform. You swear you can taste it in your food. After a while, you start to forget what clean feels like. As rough as that is for you, dirt is even rougheron your equipment. Unlike you, your gear cant grab a shower. You gotta keep it clean now or it wont work later. First, try to operate your equipment where less dirt will be stirred up. For example, dont run a generator in the dust when you can put it up on a trailer or on dunnage.Second, make sure the air filters on engines and electronic equipment are clean enough to let in the air they need. A choked-up air filter will kill even the toughest equipment. The same goes for choked-up fuel filters. When you fuel up equipment, do all you can to keep dirt out of fuel tanks. Lets face it. its a dirty world out there. You cant always keep a showroom finish on your equipment. But you can do everything possible to minimize the effects of dirt. Thats just clean thinking and good PM. By order of the Secretary of the Army:MARK A. MILLEYGeneral, United States Army Chief of StaffOfficial:GERALD B.

Crewmen, the heat can do a real number on your command post carriers 5-kW generator. So its up to you to help keep things on the cool side. Its easy to overlook something as simple as the air duct hose. But reconnecting the hose after inspecting the air lter can make the difference between a generator that does its job and one that overheats. 2 PS 786 MAY 18 3 PS 786 MAY 18 M577A3, M1068A3 Command Post Carrier Connect hose to air inlet Disconnected air hose pulls in hot air Make sure you push the air duct hose back onto the air inlet and secure it using a hose clamp when you reinstall the air lter cap. It only takes a second, and your generator will be much cooler for it. When putting the air lter cap back on, make sure that the air duct hose is still connected. If the hose is disconnected while the generators running, hot air is drawn from inside the generator. The extra heat can be enough to burn up the generator, especially in the heat of summer. whats wrong? yOu LOok teRrible! UGh. somebody forgot to reconNect my air duct Hose!

T hings can heat up inside of a Paladin real fast, especially in the middle of summer. That can have crewmen wishing for a cool breeze! But dont resort to using the micro-climactic conditioning system (MCS) as your personal air conditioner. Some crewmen open the cap on the MCs hose and use the air to cool off. While that might make things more comfortable in the short run, the MCs probably wont last. The MCs is only there to provide clean air to the crews cbrn masks when needed. Using the MCs as an air conditioner reduces the motors life. The brushes inside the MCs electric motor only last so long. Your unit will end up shelling out some cash for a new MCS. Even worse, the motor might fail when youre actually in an CBRN environment.4 PS 786 MAY 18 5 PS 786 MAY 18 hen its hot out, it can be tough for vehicles to keep their cool. Mechanics, dont make it even harder with a misstep that can cause some very expensive damage while working on an MLRS engine. Watch out for the 300WP3 cable that connects to the thermostat regulator, NSN 4820a little misstep can break the internal wiring in the connector. When that happens, the cooling fan will no longer run at high speed when extra cooling is needed. The engine can overheat. Even if you manage to catch the problem before losing an engine, a new thermostat regulator will set your unit back nearly $8,000.

First, open the front service and engine cover hatches and eyeball the sight glass on the surge tank. The sight glass should be completely full. Otherwise, hot coolant can spray from the opening, causing severe burns. its also a good idea to wear protective gloves and chemical goggles toprotect your eyes and skin, just in case. Checking coolant levels after every operation, just like it says in the -10 TMs, will help your Stryker keep its cool no matter how hot it is outside. if its not, remove the pressure cap on top of the surge tank and add coolant until the sight glass is full.

Firing Pin Limits Extended Unfortunately, there is no stock of firing pin assemblies at this time. As a result, special guidance has been issued through TACOM Maintenance Action Message (MAM) MA1 7 -044 to temporarily authorize the issue of used firing pins from unserviceable M242s that have passed inspection. These firing pins can be used for 6,000 more rounds once theyre installed on a serviceable gun. These firing pin assemblies must be inspected per the criteria provided in the MAM The MAM is on TULSA at: 8 PS 786 MAY 18 Gaining units must contact the gun card administrators to update unit identification code (UIC) information when they accept transferred equipment. The M242 firing pin must be replaced every 12,000 rounds and the breech assembly should be inspected at 25,000 rounds and every 5,000 rounds after that like it says in TM 9-1005-200-23&P. if theyre not replaced or inspected at the correct interval, there is risk of catastrophic failure or uncontrolled fire due to deformed, excessively worn, or cracked firing pin assemblies. Not good things!Not filling out a DA Form 2408-4 also causes supply problems. if round count information is lost, the firing pin must be replaced because theres no way to accurately determine the remaining life of the firing pin. Gun Card Database Click on ViEW/PRiNT. Enter the cannon and end item serial numbers of the card youre searching for. Click on active cards. When it comes up, click on ViEW/PRiNT and fill it in. Print a copy of the card. if no new or used replacement pin is available, the gun isnon-mission capable. Once firing pins have passed 15,000 rounds or used replacement firing pins have passed 6,000 rounds, they must be replaced. Units should still submit parts requisitions for a new firing pin once the 12,000 round limit has been reached or a used firing pin had been installed. That way when stock is available units can immediately get a new firing pin. The Master Gunner should update the rounds count on DA Form 2408-4s. Maintainers that have access to the TULSA Gun Card Application are responsible for updating non-firing data. A current paper or printed DA form 2408-4 card should also be maintained with the Bradleys maintenance records. The MAM also temporarily extends the life of currently installed firing pins that have reached the 12,000 round limitby 3,000 rounds.if no historical data exists for a particular gun, the currently installed firing pin can be given a life of 6,000 more rounds to re-establish rounds count if the firing pin meets the inspection criteria in the MAM.

Anything other than water, especially sugar -based drinks, will totally contaminate the water buffalo. Adding ice to the water is okay, however. But only add ice, not the bag it comes in! Yes, that seems like a no-brainer, yet it happens. The plastic then sinks to the bottom and clogs the drain and faucets. Take time to remove twist-ties or staples in the bag of ice before you hoist it up to the manhole and dump it in. These little plastic and metal pieces have shown up at the bottom of water tanks, embedded into the liners. Aside from ruining the stainless steel liners, they can also clog up the drain and faucets. Save your unit the expense and headache of repairing or replacing its M149-series water trailers. Use them the way they were intended: for water only or now that summer is here, ice, too!

A faulty seal can allow contaminants into the water, making it unsafe to drink. The water can become so Now youre not only in hot water, but youve got a hot mess to clean up, too. Replace a worn seal around the manhole cover with NSN 5330-01-317-9640. Use silicone adhesive, NSN 8040-00-118-2695, to attach the new seal.Careful Closing Cover!Before you hit the road, check where bags and gear are piled in the backseat. if your HMMWV is equipped with air conditioning vents on the backseat console, you may need to re-arrange things.Blocked A/C ventsrestrict air flow, which can cause heat exchanger issues with your HMMWVs A/C system or even blow a compressor. Carelessly tossing gear into the backseat can also break the A/C vent louvers. Those will have to be replaced withNSN 2540-01-563-3029. Lock cover open when lling tank Spread silicone adhesive here Flip latches open and away from manhole Lock the manhole cover open before closing the cover. If not, the edge of the latch digs into the cover and punctures the seal, starting the whole contamination thing over again! Scrape away damaged seal and ll gap with silicone adhesiveTime Causes Deterioration The gap between the inner tank liner and outer tank may also need attention. A recessed ring around the collar of the tank creates a seal with the manhole cover. This seal can deteriorate over time. If its not tight, it should be completely removed with a scraping tool.

Thats how you keep the vehicles engine running smoothly. To get clean air, you need clean filters! So pay attention to these two tips: Just a Squeeze Clean the Filters Squeeze dust cap to remove dust and sand Next, pop off the canister lid and pull out the air filters. The secondary filter is inside the primary filter. Tap each one with the heel of your hand just hard enough to loosen dust and sand. Then tap some more to knock stuff out of the filters. You can also use low-pressure air psi or lessto blow from inside to outside of the filter. Thats the best way to remove sand and dirt from the filter. Just never bang the filter on a rock or hard surface like the vehicles tire. And never use high-pressure water to clean out the filters. Replace the primary filter when its damaged or when the air cleaner indicator stays in the red after a cleaning. Replace the secondary filter after cleaning the primary filter three times. Remove cannister lid and pull out primary and secondary air lters Replace primary lter if air cleaner indicator stays in red after cleaning C o u g h M1231 Husky my air fiLTErs sure COuld {C o u g H} use A GoOd cleaning {C o u g H}!

The most basic way to keep CROWS working is for units to do weekly PMCS like theyre supposed to. That not only ensures CROWS is in good shape, but helps operators remember their CROWS training. But, unfortunately, too many CROWS systems sit neglected in motor pools. Units dont know if their CROWS even work until its time to go to the field and then its too late to get them fixed.

23 PS 786 MAY 18 CROWS Diagnostic Kit Many CROWS units, however, have not received the CDK. if your unit hasnt, be patient. CDKs are being fielded and eventuallyall CROWS units will have the CDK. Once youve located a CDK, thenext step is to update the software on your MSD. This includes the software that lets the MSD and CDK communicate and the Automated Software Download (ASD) program needed to reload or update CROWS software. Both pieces of software require the user to have administrative privileges for the MSD. MWO Required if your M153 CROWS has software version 3.5 or below, it needs to be updated using MWO 9-1090219-23-1. Report the upgrade in the Modification Management Information System (MMIS) in LIW. Special Operations units with CROWS software version 3.10.2 dont need to do the update. For permission to download the software, fill out the software access request agreement at: Some CROWS units are unaware of a major source of help: the CROWSdiagnostic kit(CDK), NSN 6625-01-612-3560(LIN FG25BQ). CDK s have been fielded with all CROWS systems since August 2014. But often the CDKs dont make it into the units property books and end up stored and forgotten. Along with the CDK, units are also supposed to receive special tools for maintaining CROWS. Units need to check to see if they already have the CDK. The first step should be a search of property books by theCDKs NSN. heres where to look: For echelon above brigade (EAB) units, such as MP and engineer battalions, the CDK/special tools should be at the battalion HQ maintenance (HHC/HHD). For maneuver brigades, CDKs should be in the forward support companies and the maintenance company of the brigade support battalion.

Roughly 75 percent of the CDKs issued are not on unit property books. if the NsN doesnt show up, dont stop there! Without the CDK and the special tools, units cant diagnose and fix problems. Units should search for CDK and special tools They can also be contacted for any questions about CROWS CROWS maintainers should have received CDK training either from TACOM instructors or in AIT for the 91B MOS.

24 PS 786 MAY 18 Your weapons -10 TM provides all the info you need for helping your weapon beat the desert. Here are a few ways to help your weapon win its battle with the desert:here are more differences between the M249 and M240L short and long barrels than just the length. The M249 long barrels are BII (basic issue items), which means they must be kept with the weapon at all times. The short barrels, though, are additional authorization list (AAL) items, which means theyre optional and not required. What does that mean for armorers? You must always keep both long barrels, even if you get short barrels for your M249 machine guns. Since both long barrels are BII, they must be turned in with the weapon. But its a different story with the M240L. MWO 9-1005-313-23-4 is replacing its long barrels with short barrels. Once that happens, the short barrels become the standard barrels and BII and must stay with the M240L at all times. Pay special attention to moving parts like the bolt carrier.Wipe and brush them clean. Blow out sand from areas like the trigger assembly that youre not allowed to take apart. Easy on lubricating exposed surfaces. Lubricants like CLP attract sand. Clean and lube only internal parts frequently and generously. But wipe the outside of the weapon completely dry. Clean magazines, too. Magazines jam with sand. Unload and wipe off ammo daily. Run a rag through the magazine. Dont put any lube in magazines or on ammo. Use rifle covers, muzzle caps, and spare magazine bags. Cover mounted machine guns. Keep the M16/M4s ejection port cover closed and a magazine installed. The desert is a very tough place for your rifle, machine gun or pistol. Blowing sand invades openings like the muzzle and ejection port and stops moving parts from moving. And the deserts extreme heat dries up lubricant. Even worse, the sand mixes with lube and becomes a scouring powder that grinds up parts. Clean and do PMCS often.That means at least daily in the desert. Even wiping off the outside of your weapon with a clean cloth every chance you get will help. Cleaning that involves disassembly should be done only in enclosed areas, like your tent or quarters. Otherwise, blowing sand will make your cleaning useless.

IRT16####-###, for example, means the canister was manufactured in 2016 These TVI and pre-201 7 IRT canisters are leaking carbon. The carbon can build up in the outlet valve area, leading to mask failure. Carbon dust can also cause mild eye and respiratory irritation. Most importantly, in a chemical environment, the mask could fail to protect. All canisters with a lot number beginning with MMB are OK to use. Order replacement canisters with NSN 4240-01-361-1319.

The polynomial spline visor creates a better interface with sights like the M68 close combat optic, which lets you engage targets with both eyes open. That helps you both hit the target and maintain situational awareness. The visor also makes it easier to use night vision equipment and binoculars. the one-piece eyelens provides a field of view that is at least 80 percent greater than what you had with the M40. The M50/51s dual filter system makes it twice as easy to breathe as compared to the M40. That increases your endurance and cuts the time needed to accomplish a mission. This lets you see more without having to turn their heads, which means: my urethane eyelens itself wont yellow as easily as the M40s and is much more resistant to contaminants and scratching. so you wont have to worry about my eyelens getting scratched! Dual lters help breathing The dual filter system gives better weight distribution to the M50/51, making it more comfortable than the M40. The masks inner parts are made of silicone, which is softer and easier on the mouth and nose. The head harness comes with a skull cap, which provides a more comfortable fit and makes it easier to put on the harness. Breathing easier also makes for better breath control during firing, which boosts marksmanship. 786 28-29.indd All Pages 3/15/18 10:52 AM

45 PS 786 MAY 18Dear Editor, Through our work supporting Gray Eagles, we offer these tips to help them soar: Dont overtighten the captive fasteners. The fasteners will break the nut plates loose if you muscle up on them. Also keep an eye on the tool used to tighten the fasteners. If the tools tip begins to round out, its time to get a new tool. Otherwise, youll start rounding off the fasteners themselves. The correct torque is 25-30 in-lbs. Thats tight enough. Careful installing the aft cowl. If you force things, the aft cowl gets warped and wont fit. Weve found its easier if you first secure the fasteners behind the radiator before you secure the rest. Use five people, not four, to move the Eagle. We have the extra person pushing on the landing gear. He not only adds muscle, but helps brake if necessary. Otherwise, one Soldier must do most of the pushing while the other three make sure the wings dont hit anything. Remember to remove the landing gear steering servo pins before towing. That lets the landing gear turn freely. If the pins are left in, the servo and landing gear get damaged. And its so easy to forget the pins. Just make sure you reinstall the pins before takeoff. SGT Richard Spivey Ft Hood, TX Stow the tow bar in the towing vehicle when youre through towing. Crews sometimes forget to remove the tow bar and then they back over it with the towing vehicle. Make it a habit to immediately stow the tow bar when youre done towing.

This condensation can affect electrical plugs, jacks and connectors. If condensation is affecting your commo connectors, tape over all connectors that may be exposed to moisture overnight. This prevents that moisture from contaminating the contacts. Plugs should be dried before inserting them into equipment jacks. Excessive moisture or dew should be removed from antenna connectors to prevent arcing. A Little More Cleaning Keep all cooling fans clean and vents clear of clogging Use a brush or compressed airwhatever your equipment TM saysto clean the fan and the areas around it. Static electricity is common in areas of extreme, dry heat. Its caused by windblown debris and extremely low humidity. Poor grounding conditions aggravate the problem. Make sure your equipment is properly grounded. Use tip caps on all antennas to cut down on wind-caused static discharges. If you have any broken or missing knobs, switches or connectors, get them replaced before the heat hits. Check the whip antennas mast base to be sure the contact is clean. If its dirty, use low-pressure air or a soft brush to clean it. Electrostatic Discharge A Few More Things Room to Breathe Give your communication equipment room to breathe.

54 PS 786 MAY 18 55 PS 786 MAY 18 Dear Editor, PS publishes so much information that can really help operators and repairmenIF THEY S IT! We run into too many Soldiers who have only a vague idea what PS is or who rarely see it. So that valuable information never makes it to the Soldiers who could benefit. Here at Ft Braggs Logistics Readiness Center (LRC), we boost knowledge by posting articles on bulletin boards close to the repair shops. Each month we check PS for the most helpful articles, print them out and post them. We put small arms articles next to the small arms shop, truck articles next to the truck shop and so on. Soldiers read the articles while theyre waiting for their equipment. We also post relevant safety and maintenance messages. Support shops can do the same thing. And so can individual units. Just find an area where Soldiers congregate and post articles there. It takes only a few minutes to go through PS online each month to see if there are articles that could help your unit. Michael Dorsey Ft Bragg, NC Editors note: What a great idea, Michael. Units can do PS PS app. Thats important since PS only available digitally. Well gladly email you a PDF poster about the app that you can print out. Just email: usarmy.redstone.logsa.mbx.psmag@mail.mil LOGISTICS Good PS Info? Post It! GCSS-Army Decoded GCSS-Army Reminder Turn In OCIE ASAP! Mr. Dorsey has an excellent way for units to make sure their Soldiers see PS articles that help them. Print the articles and post them where Soldiers gather. 786 54-55s.indd All Pages 3/14/18 9:32 PM
