The shear pin replacement kit, NSN 5308-20-008-6803, is a critical part of the EA seat that helps to protect you during a blast. The wrong gas spring has a solid silver tip on both ends and is four-and-a-half inches longer than the right one. if you install the wrong gas spring, the gas cylinder and lower mounting bracket, NSN 5340-21-921-3610, are damaged. A damaged pin means the seat cant keep you safe if your vehicle hits a mine or IED. its also marked with part number C16-26949. Double V-Hull Stryker Even worse, the wrong gas spring cant support as much weight. So the engine hatch could fall and hurt someone! Crewmen, being in a hurry can cause you big problems! especially if you jump through the hatch of your double V -hull Stryker into the drivers or commanders seat. easy, feLla! whats the big hURrY? Drivers and vehicle commanders, be sure to ease through the hatch onto your seat, being careful not to place all your weight on the seat at once. Be really careful if youre wearing full combat gear. Thatll help protect those shear pins from breaking. Also, dont replace a broken shear pin with a standard bolt. The EA seat wont work right with a standard bolt and thatll make your Stryker NMC! Take a look at the shear pins on your vehicles driver and commander seats. if the bolt head isnt bright red, ask your mechanic to make sure that a shear pin is installed.

Rust Busters Tip of the Month Delaminated Windshields: More Q & A Corrosion these are the telltale signs of potential corrosion problems that call for proper surface preparation and spot painting. But the success of spot painting depends on surface preparation,which hinges on two critical prep steps: 1) cleaning and2) roughening. Small spots of bare or rusty metal need field-level attention to prevent a larger and more costly corrosion problem. Fortunately, these trouble spots can generally be cured withspot painting. Bare metal corrodes fast, resulting in costly repairs and reduced readiness. iF YOU PAY ATTENtiON to theSe Tips, I CAN BE pRoTeCtEd!

Prep Step #1: Cleaning12 PS 790 SEP 18 13 PS 790 Before spot painting, surface cleaning must be done to remove dirt and grime. if the surface isnt clean, paint wont apply evenly. if you see grainy bumps or streaks during painting or as the paint dries, its a sign that the surface wasnt clean. The new paint will likely peel or flake, wasting your effort and resources.So do it right the first time! Clean the surface of any: dirt, salt, lubes, and contaminants. Coming next month in PS Magazine: s p o t p a i n t i n g t i p s Rinse the area well afterwards and let it dry completely. Prep Step #2: RougheningPower tools, like automatic sanders, or hand cleaning with abrasive paper and wire brushes are acceptable abrasives. if you use power tools, however, make sure you wear proper protective gear and follow environmentally compliant methods to power grind surfaces using a HEPA vacuum. Sand the area and feather the edges to provide a smooth transition from old coating to base metal. Lightly sand the surrounding intact paint with a fine grit abrasive cloth (200 grit or higher) to slightly roughen it without removing any paint. Taper old paint and primer edges down to bare metal Original primer Original topcoat Bare metal Choose abrasive materials and their degree of grit based on the type of metal underlying the bare or rust spot. For example, 80 to 100 grit abrasive cloth is best for removing rust or cleaning and polishing iron and steel surfaces. However, dont use anything more abrasive than 100 grit on close tolerance parts because it could cause damage. if you skip or skimp on this important step, the paint wont stick and once again, your efforts will be wasted! it might take more than one of these methods to fully clean the surface, depending on how dirty it is. If surface isnt clean, paint wont stick can YOu name the four best methods for proper surFace cleaning? Detergents! solvents! alkaline cleaners! steam cleaning! Do this ASAP to prevent the freshly sanded metal from rusting. Once the primer cures, youre ready to paint! Within four hours of sanding, wipe the surface with cleaning solvent. Let the area dry completely after this final cleaning, then apply a pretreatment (typically a primer coat). Use automatic sander, wire brush or sand paper to roughen surfaces After a thorough cleaning, the surface must be roughened with an abrasive material. 790 12-13.indd All Pages 7/15/18 12:33 PM Additional Resources For pretreating ferrous surfaces, follow TT-C-490F For aluminum, use MIL-DTL-5541F More guidance on surface prep and spot painting is also available in TB 43-0213, WP 0032 & 0033, Corrosion Prevention and Control (CPAC) for Army Wheeled Vehicles (Sep 12).

D oD Manual 4160.28, Defense Demilitarization, Vol.2 (Mar 201 7 ) has information on the current policy, if you need further guidance. Delaminated up-armor ballistic glass windshields have a demil code of D. This mandates total destruction of the item in such a way that prevents restoration or repair. Once the panels are destroyed, turn them into DLA Disposition Services (formerly DRMO).

Dear Editor, While teaching Soldiers ho w to operate and maintain the Buffalo route clearance vehicle, Ive come up with a few ways to keep the Buffalo clearing trails: Check the red do t on the front and rear cameras.

18 PS 790 SEP 18 19 PS 790 Use two people to check the air digger compressor reservoir. To actually check the sight glass, you must remove three bolts on each side of the 95-lb door and then lower it. If you try to do that on your own, youll end up walking funny. Use a 17mm sock et to remove the bolts while your helper holds the door. The sight glass should be 1/2 to 3/4 full. Stencil Vanguard Compressor Oilen on the reservoir door so you dont mistakenly put hydraulic fluid in the reservoir. Then have your helper hold the door in place while you reinstall the bolts. That helps prevent cross-threading. Easy does it with the air tank pressure relief cables. Yanking on the cables eventually breaks them and it takes hours to replace a cable. Pull on the cable just until you hear air coming out. Thats far enough. Dont let the fuel nozzle scrape the side of the fuel tank opening. Rust tends to form there. The nozzle breaks the rust loose and contaminates the fuel. The only way to clean out the rust is to drain the tank. Remov e the hydraulic tank fluid cover with a 19mm hex socket and a 1/2-in drive. The TM doesnt mention that these tools are required. As a result, the check is missed, which leads to arm failures. Easy does it with ladder. When crews exit the Buffalo, they sometimes let the ladder slam down. That bends the ladder and its hinge points and breaks the cable. Lower the ladder by its cable to avoid damage. And remember to lock the ladder in place once everyone gets inside the Buffalo. That way it wont slam down when you hit the first bump. Step directly on the ladder release. If your foot is at an angle, you can damage the release. If the release sticks, lube it with CLP. Fuel ller opening gets rusty Keep fuel caps lubed. When fuel caps become difficult to turn, give their threads a light coat of G. Otherwise, the caps can eventually seize. Dont yank air tank pressure relief cables Lower ladder by cable and dont drop it Step straight down on ladder release 19mm hex socket required but not mentioned in TM 790 18-19.indd All Pages 7/15/18 12:35 PM

The hose coil is spring-loaded. If the spring is worn, the hose hangs up. Try raising the arm 45 degrees and then extend and retract it. That usually fixes it. If this happens a lot, tell your repairman so he can replace the spring. Strap everything down before hitting the road, including yourself. Getting thrown around the vehicle or being hit by a flying TM is as dangerous as the IEDs. Ive seen Buffaloes completely stood on end by IEDs.

The three previous PDF manuals (TM 1-2840-24823&P-1, -2 and -3) are rescinded. Thats because of the new PDF button feature within the IETM that allows users to open each work package (WP)en in PDF format. New Apache Flyers Helmet TM Available T700 Engine Manual Only in IETM AWR 980 identifies all authorized rescue devices that can be attached to the hoist. But some units dont know how to inspect and maintain hoist devices. Thats where AWR 980en comes in! it gives you maintenance, operation and inspection information for each rescue device. when was the last time you loaded each seat paddle with 250 pounds and suspended it for 30 minutes to verify a load test? Has it been more than 180 days since the last inspection? How do you know the seat is still serviceable? H-60L/M if you use the #420 rescue seat, here are some questions for you: For example, the #420 rescue seat should be maintained and operated based on the instructions in NAVAIR 13-1-6.5. it specifies a placed-in-service inspection for the seat, along with a 180-day recurring inspection that includes both a tension and load test. These devices must be able to hold the weight so they dont fail during a rescue mission. if you cant answer these questions, get the required inspections done before you use the seat again. And the same goes for all other authorized devices for the rescue hoist. in addition, make sure you track the inspections for each rescue hoist device. Thats the only way to ensure personnel can be rescued safely. I suRe Am Glad they Take rescue seat maintenance seriously. You play a similar role by properly maintaining and inspecting those devices. Now that the e-model Apache Aviator Integrated Helmet (AAIH) system has hit the streets, maintaining it becomes important. So crack open the new TM 1-1680-392-13&P for all the good PMCS and maintenance tips. Inspect and maintain rescue seat like it says in AWR 980 and NAVAIR 13-1-6.5 you got me? youRe gOod to Go!

41 PS 790 SEP 18 Dear Editor, As a TAC OM LAR, I see mortar units use a hammer to tighten the breech caps on M120A1 mortars too often. That can cause the barrels white line not to align with the firing pin, which shortens the M120mm cannons life. The correct way to install the breech cap, according to WP 00312 in TM 9-1015-256-13P, is to first give the breech cap threads a light coat of G grease. Then tighten the breech cap by using the cap removal tool. Back off a quarter turn and then use a jerking motion to finish tightening the cap. The white line on the barrel must line up with the firing pin.

Keep Your DistanceStay at least two meters away from other Minehound operators. if there are four or more operators, make that 10 meters. Otherwise, youll interfere with each others readings. Use the automatic channel selection to find the best channel for eliminating electromagnetic interference (EMI). Keep the Detector Search Head Parallel to the Ground Thats very important on uneven ground. if the head is at an angle, it can give you false ground penetrating radar (GPR) readings, which could lead to disaster.

44 PS 790 SEP 18 Dear Editor, Here are a few things Soldiers need to watch out for when using and caring for their M50 masks: Easy with the outsert. Its damaged more than any other item on the mask. Soldiers force it off, which breaks the outsert tabs and cracks the center of the outsert. The correct way is to grasp the top and bottom of the outsert with both hands and twist it up. It should come off easily. If it doesnt, dont force it. Tell your CBRN specialist. Never go to the field without the outsert. If an outsert is damaged, it can be replaced for less than $20. If the eye lenses are damaged, the facepiece assembly must be replaced. CBRN specialists should keep extr a outserts on hand. Theyll need them. After cleaning the mask, check for the nosecup retaining ring. It often disappears and you dont notice until the nose cup falls out. If the retaining ring is missing, you must order a new facepiece assembly. For storage of more than 30 days, install the faceform. That helps the mask keep its shape. The head harness straps just need to be snug for storage. If you over-tighten them, they lose their elasticity. Himars units are nding vehicles with cracked rear cab support latches. That could be dangerous if the latch fails. The cab could pitch forward during a hard stop. Before and after operations, crews need to check the support latch for cracks where the latch bracket is welded to the frame. Also look for any loose bolts securing the bracket to the frame. Clean the area of any dirt before inspecting the support latch and its welds. Look closely. Dirt and CARC paint can make it difcult to see cracks. Any cracks or loose latch bolts make the HIMARS NMC. This cab latch bracket check will be added to Item 8 in TM 9-2320-450-10-2s PMCS. Editors note: Excellent advice, Sergeant. Thanks. Check cab latch bracket for broken weld or loose bolts After cleaning, make sure nose cup retaining ring is still in place Hold both sides of outsert and gently twist up Use serial number for tracking The M50, unlike the M40 mask, has a serial number. You can use the serial number to make accountability easier in accordance with your unit SOP. G Christopher Butler Ft Leonard Wood, MO M50 Protective Mask HIMARS C a t c h C a b l a t c hC r a c k s!

46 PS 790 SEP 18 47 PS 790 Dear Editor, Through our work maintaining AN/PVS-14 and AN/PVS-7B/D night vision devices at our Logistics Readiness Center (LRC), we offer these tips to help Soldiers see in the dark: Dont remove the light interference filter (LIF). Some Soldiers think the LIF just gets in the way and they take it off. Its critical, though, to keep it screwed in.

49 PS 790 SEP 18 Ca ble and Wire Handbook Drops A new publication, Training Circular (TC) 6-02.20, Cable and Wire Systems Handbook (Jan 18), is available. The TC is a reference for personnel who install, maintain, test, troubleshoot, repair, fabricate, replace or recover wire and cable for Army communication networks. The pub covers installing and recovering wire and cable lines, pole climbing, splicing, wire ties, troubleshooting, wire line construction and wire records. Local area and wide area networks are also covered. T o download, look for TC 6-02.20 at: https://armypubs.army.mil/ProductMaps/PubForm/TC.aspx New TM for AN/PSQ-39 TM 11-5855-344-10 (Mar 18), the operators manual for the night vision AN/PSQ-39 viewer, NSN 5855-01-650-2680, has been released. Distribution is restricted, so youll need to log in with your CAC to the Logistics Information Warehouse at: https://liw.logsa.army.mil/ Then choose the ETM/IETM icon and search for the TM by Pub Title T ext, AN/PSQ-39. MEP-804B Alternator NSNGet a direct current alternator for the engine used on the 15-kW, 50/60 Hz, MEP-804B generator with NSN 6115-01-382-3940 (PN 581200-33-0). It replaces NSN 6115-01-5609146, which is shown as Item 8 in Fig 12 of TM 9-2815-254-24P (Jun 10). Please exhaust NSN 6115-01-560-9146 rst because its a terminal item. Editors note: We clearly see that these are great NVD tips. Thanks and thanks again. Check for the battery cap retainer. If the retainer is gone, the battery cap soon will be missing, too. Then your NVD is useless. Order a new retainer for the AN/PVS-14 or the AN/PVS-7-B/D with NSN 6160-01-448-6355. As always, REMOVE THE BAERIES FOR STORAGE. When we go to units, we usually find half the NVDs stored with their batteries installed. The batteries leak and soon corrosion has ruined the NVD. It takes just seconds to remove the batteries but saves thousands of dollars in the long run. Make battery removal part of the turn-in process. Eric Shove Danual Smith Ft Bragg, NC Use lens paper, not your shirt, for cleaning. Rough material like your shirt scratches delicate and expensive lenses. Your NVD shouldve come with a package of lens paper in the carrier. If its missing or used up, order NSN 6640-01-459-4239 for 50 sheets or get 100 sheets with NSN 6640-00-240-5851. Some units are using a new cleaning device called a Lenspen. One end is a brush and the other is a cleaning tool. Order it with NSN 1240-01-535-0972. It costs less than $7. Pack with care. Soldiers often put the NVD in its storage bag and then stuff the mount on top of it. That usually results in a broken monocular housing, which lets the dry nitrogen leak out. The NVD fogs up and is difficult to see through. The gain control knob and power switch can also end up broken. Soldiers should store the NVD in one compartment of the carrier and the mount in the other compartment. And dont toss the carrier down or pile stuff on it. Remember the carrier doesnt provide that much protection. Store NVD and mount in separate compartments of carrier while I realize its important I go in the arms room, I do insist, my good man, that you first remove my battery. its a matter of preservation, dont you see.

50 PS 790 SEP 18 Dear Editor, Too often in my work as a CECOM Sensor LAR, I see systems with problems because the KG-250 encryptor doesnt work. The majority of the time, its due to a tamper issue, or else the purple light of death. Tamper issues are often resolved by resetting the encryptor with the appropriate tamper key. However, if inserting the correct tamper key doesnt work, then the device needs to be turned in through the Armys Information Systems Security Program (IP) process for repair. The purple light of death means the internal battery has expir ed. In that case, the KG-250 must also go through the IP process. Once the internal battery is drained, the KG-250 needs sustainment-level repair. The KG-250s internal battery should last thr ee years if the device is properly maintained. Theres a smaller 1/2 size battery and housing, but it only extends the internal battery for three months. Theres a huge difference in the storage time. Soldiers seem confused as t o which battery should be used for long-term storage. Too often they let the KG-250s internal battery go dead because they arent using the proper battery storage option. Switching all KG-250 encryptors over to the longer-life C-cell battery and housing will eliminate a lot of internal battery failures in KG-250 encryptors Army-wide. Soldiers can order the C-cell batt ery with NSN 6135-01-435-5558 and the C-cell battery housing with NSN 6160-01-575-7749. These will greatly increase the KG-250s lifespan. IP Repair Process for CONUS The IP process f or KG-250 exchange has a few steps. One step involves the units property book officer, but its not too complicated. For instructions and assistance in r eplacing or repairing KG-250s, contact Anthony Black at IP, (520)538-8005, or IP customer support at (520)538-1829/8381, or email: usarmy.huachuca.cecom.mbx.ilsc-csla-issp@ mail.mil Note: OCONUS users have different shipping requirements. Verify with IP before shipping to CONUS directly.

Well, proper accounting or correcting issues at the property book level can boost a units overall readiness ratings. And thats a good thing! Bolt-on armor kits (B-kits) give a welcome additional layer of protection to heavy and medium tactical vehicles. But for property accountability purposes, B-kits are consideredseparate components from the vehicles. This means that B-kits must be accounted for separately in Global Combat Support System Army (GCSS-Army). Hmmm. Wonder why our readiness ratings took a hit? Did ya forget that this classy armor needs to be reported separately in the property book? 790 58-59.indd All Pages 7/15/18 12:40 PM
