4 PS 787 JUN 18 Dear Editor, Follow these suggestions for Stryker success: Editors note: Excellent steps to Stryker success, Sergeant. Thanks. If the cable is in f ront of the cutter with the cutter upright, both the cable and cutter will wear against each other and one of them will fail. The cable needs to be behind the cutter with the cutter in the down position. If you dont cover the Stryker in rainy areas, water runs down in the exhausts for both the engine and cooling module. Water collects in the hull and eventually causes electrical and corrosion problems. Clip the cover to the hold-down clamps to keep it secure. Even if you do keep your Stryker covered, its still a good idea to open all drain plugs monthly and let any water in the hull drain out. Make sure you use drip pans and dispose of the water according to your units SOP. SGT Paul White Ft Carson, CO Every time you drain and refill the hubs, install a new seal, NSN 5330-12-156-4524. Otherwise, the seal will probably leak and the hub could run low on fluid. Next thing you know, the hubs are damaged. Dont reuse the copper seals for the wheel hubs. Route the winch cable behind the wire cutter. Cover and drain. If winch cable is routed near wire cutter wire cutter is easily bent Replace seal and torque to 22-25 lb-ft when reinstalling drain plugs Open all drain plugs monthly to let water drain out want your STRYker to be a sucCesS?

M2/M3-Series BradleysWho Services the M242?M119A2/A3 Towed HowitzersKp S a f e During Fire Miions! You should know that the BOP guidance shown in TM 9-1015-25210 (Sep 10) regarding the allowed number of rounds (ANOR) a crew can fire in a 24-hour period isoutdated. The short answer, sir, is no. The 91F small arms repairman is the only MOS trained to work on the M242. its important to note that crew members, regardless of MOS, who graduated from Ft Bennings Master Gunner School and acquired the additional M242 skill identifiers (ASI) of the course are authorized to do some maintenance tasks and services (-10 and -20 level) on the M242. Master Gunners cant, however, do -30-level tasks, such as working on the feeder drive or worm shaft assemblies. The 91Ms maintain the Bradley turret, not the weapon itself. Their job is to diagnose and troubleshoot problems and do maintenance on the turret and fire control system. The M242s TM 9-1005-200-23&P has not yet been updated to reflect the new twolevel maintenance format, but it soon will be. in the meantime, Bradley units should note in the -23&P that the 91F should do all organizational and direct support maintenance on the M242. However, the BOP guidance in TM 9-1015-26010 (Nov 1 7 ) is correct. The BOP guidance in the previous edition of the 260-10 is outdated. man, yOu Sure arE lOud!

Then soak the hold-downs in the baking soda solution. Give the hold-downs a good rinsing. After theyve dried, apply epoxy coating to each of the hold-downs. You can also use bituminous coating if the epoxy isnt available. Wash the battery tray with the baking soda solution. Rinse thoroughly and allow it to dry. Apply a 1/32to 1/8in thick coating of epoxy, NSN 801001-313-8702, or bituminous coating, NSN 8030-00-290-5141, to the box. Reinstall the batt eries after everythings dry. Before you reconnect the battery clamps, put a light coat of silicone compound on the tops and sides of each battery post. This special compound runs down around the battery post and terminal to completely seal out moisture. Get a 3-oz tube with NSN 8040-01331-7133 or a 1-pt can with NSN 804001-331-7134. Doing all this will keep y our tanks batteries ready to go and increase your units combat readiness. CW3 Robert Bynum Ft Stewart, GA Editors note: Crewmen should clean up with these tips. Thanks, Chief! Wash dirty, corroded battery box with baking soda solution Coat battery posts with silicone compound before reconnecting clamps Remove all batteries before cleaning Dear Editor, Some cre wmen overlook the batteries when doing preventive maintenance on their M1-series tanks. That leads to corrosion and corrosion leads to a tank that wont start! Make sure you clean the battery, battery cables, battery box and hold-down supports. Sure, that takes a little time and effort. But its time and effort well spent.Battery Clamps and Terminals Use a battery t erminal cleaner, NSN 5120-01-615-6464, to scrape away heavy corrosion from the battery clamps and terminals. Then clean with a solution of 1/2-pound of baking soda to one gallon of water. Get one pound of baking soda with NSN 6810-00-264-6618 or 100 pounds with NSN 6810-00-290-5574. Use the battery terminal brush, NSN 5120-00-926-5175, for the best results. After cleaning, inspect and replace any clamps that will no longer fit the battery posts or whose ends touch when the clamp nut is tightened.

These hub and drum conversion kits, NSN 2530-01-6437 190, were missing the whole hub assembly! A while back, a new single-piece wheel came out as a replacement for the old split-ring rim on M8 7 0A1 semi-trailers. it was exciting news (in the wheel world, at least). But the excitement didnt last long. eed a new cap for the brake master cylinder on your M1101 or M1102 light tactical trailer? Dont use NSN 5340-01549-5983, which is shown as Item 7 in Fig 8 of TM 9-2330-392-13&P (Dec 12). That old cap is marked to use commercial DOT uids in the cylinder when youre supposed to use the MIL-B-46176 brake uid called out in the TM. Order a new, correctly marked cap with NSN 2590-01-664-6765. And make a note until the TM is updated. rf M870A1 Semitrailer M1101, M1102 Light Tactical Trailers rf The right cap can prevent use of the wrong brake fluid. Ill tell you what! DLA launched an investigation, and the story took adramatic turn. DLA found that the contractor tried to piece together the hub assembly instead of purchasing it as required from the source. But the contractorcouldnt provide theactual hubs, which made the conversion kits useless. Without the conversion kit, the M8 7 0A1 cant be mounted with the new single-piece wheels that are meant to replace the split rims. New kits that include the hub should now be available. dang it!

Use Report Control Number W90DY41 7 0002 and file the PQDR through the Product Data Reporting and Evaluation Program (PDREP) : in the meantime, DO NOT trash the kits. Youll need to hold onto those until your unit is given disposition instructions from the PQDR.

Youll find one next to each of the wheel assemblies brake caliper and disc. The PMCS tables call this an axle swivel fitting, while the parts manual lists it as a trunnion fitting. Either way, the fitting needs to be lubed weekly. Dont forget the axle swivel fittings up top need the same treatment. The recessed area where the fitting is mounted gets clogged up with mud and dirt, so the fitting is easy to miss. Pry out any crud and wipe the fitting with a clean rag. Then give it four to five shots of grease. When youre finished, make sure to put the red plastic cap back on the fitting to keep out dirt. if its missing, order a package of 10 new caps with NSN 4 7 30-99-142-5123.

19 PS 787 JUN 18 Editors note: A gold mine of mine detector tips! Thanks, Sergeant. Beware of RF. Electrical interference can hurt detectors detecting ability. Dont carry a cell phone or radio. Stay at least two meters away from anyone else operating a mine detector. Always be aware of where other Soldiers are sweeping. Stay at least 25 meters away from mounted systems that block RF to IEDs and at least 10 meters from manpack systems that do. Take a break. Rotate with another operator every 20 minutes to prevent fatigue that could cause you to miss a signal. we share these tips with our students at the combat engineering school at fort leonard wood. Mine Detectors Tips for Better Detecting!hello, Im StafF Sergeant Marvin Hamler and here are a few Before use, prepare and calibrate the detector so it can adapt to the soil it will be detecting in. That tells the mine detector what minerals are in the soil and helps prevent false readings. If the terrain changes, calibrate again. That way you dont waste time trying to find a non-existent mine. Remember LO:L = lane coverage O = operator stance S = sweep speed S = search head position Keep the det ector search head parallel to the ground and no more than two inches from the ground. Thats especially important on uneven ground. If the head is at an angle, it can give false ground penetrating radar (GPR) readings. That could cause you to miss a mine. Try to sweep one meter per second across a 1-meter lane. If you sweep wider or faster, youll have less control and more fatigue. did yOu make sure Im calibrated for this soil?

20 PS 787 JUN 18 21 PS 787 JUN 18Dear Editor, Through our experience keeping Gray Eagle UAVs flying at Ft Wainwright, we offer these tips: When checking for FOD, look in the lower aft cowl. Debris tends to collect by the mounting bolts. Also be on the lookout for water and oil in the cowl. They can affect the material that makes up the Gray Eagles body. The lubes and coolant glow under black light, making them easier to spot. Keep the door to the ground control station closed. Otherwise, the ECU has trouble cooling the equipment. Then it overheats and shuts down. The door also blocks out RF interference and keeps the enemy from spotting the lights inside. Easy does it with the ground control station headsets. Rough handling damages their padding and microphones. If youre not using the microphones, hang them gently on their hooks inside the station. Never toss them. It costs $2,000 to replace them.

A hoist motor has no oil, but there must be enough oil in the drum assembly to prevent additional friction that can cause premature motor failure. Youre required to check the oil level every six months. And make sure you keep to include visual checks of the end covers for oil leaks, like it says in WP 1222 00 of TM 1520-280-23&P. An empty reservoir will hold 17 ounces of oil. Since adding oil takes time, youll need a little patience when doing the job. Filling too fast can cause a vacuum that requires some settling time before more oil can be added. if you have IAFS combo paks that need repair, send them to: Corpus Christi Army Depot Plant 7015/RIC B52 Corpus Christi, TX 78419 So get on board the return train and turn in unserviceable internal auxiliary fuel system (IAFS) combo paks,NSN 1660-01-519-4248(PN HM025-600-11).

36 PS 787 JUN 18 S ma Arms help from Ft Carson Think relaxed for storage. Armorers store weapons cocked. Why? Soldiers lock and clear their weapons before they turn them in to the arms room. Armorers leave the hammer cocked and the bolt locked to the rear when they put the weapon in the rack. That tension on hammer and trigger springs causes them to weaken. Then the springs have to be replaced. Leaving the bolt locked back also weakens the recoil spring, which could cause jamming. Things get ev en worse with the M16 rifle and M4 carbine. Storing them cocked can also cause them to fail the trigger pull test. Then the hammer and trigger pins must be removed and reinstalled. If that happens too often, the pins holes enlarge and fail gaging. Then the lower receiver must be replaced. If armorers do this every time they store a weapon, all those problems disappear: Leave the bolt or slide forward, the selector on SEMI for the M16/M4 or off SAFE for pistols and machine guns, and the hammer uncocked. Help the springs for the M2 and MK 19 last longer by storing them muzzle down when possible. Pay attention t o the M2s feed. If you get the feed wrong, youll not only be unable to feed ammo in the M2, but youll also damage the feed pawl guide lever when you slam the feed cover in place. Just a glance at the bolt swit ch can tell you if youve got the feed right. If youre firing with the left-hand feed, the left groove beginning at the bolts base should run through the bolt switch unblocked. Right hand feed? The right groove should be unblocked. M2 gunners should be reminded t o always check the feed before firing. Dear Editor, At the Logistics Readiness Center (LRC), w e see these small arms problems repeatedly. Soldiers and armorers can make it easier for themselves and their weapons by remembering these tips: Lube like it says in the weapons -10 TM. We see weapons at either lubing extreme: bone dry or dripping with CLP. A weapon stored with no lubrication will soon be attacked by corrosion and damaged, maybe severely. A weapon with too much lubrication will quickly have firing problems in the field. Every -10 TM has very precise lubing directions. Follow them! Its a good idea for armorers to make copies of the directions and give them to every Soldier. Correct lubing is also a good topic for Sergeants Time Training.

It works great for lubricating and preserving rubber parts, like O-rings. It doesnt swell or soften the rubber, which hydrocarbon-based greases can do. Silicone grease does a good job as a corrosion inhibitor, especially when a thicker lubricant is needed. And its electrically insulating and doesnt break down when high voltage is applied. That makes it good for electrical connectors, particularly those containing rubber gaskets. It lubricates and seals rubber portions of the connector without causing arcing. Order an 8-oz tube of silicone grease with NSN 6850-00-880-7616. But you dont want to use silicone grease in sandy areas because it attracts sand. Then its better to use a dry silicone spray. It has some cleaning ability, but its main advantage is that it dries almost instantly and doesnt act as a magnet for sand. Order silicone spray with NSN 7930-01-380-9028. That brings a dozen 11-oz cans for around $150. Or you can buy a single can with NSN 9150-01-039-4745. There are no authorized directions for camouflage painting sniper rifles. Camoufge? Wh Weapons Can YouCamoufge? of Course, SergeANt! Remember you must get your commanders approval before painting M16s, M4s, M240s or M249s. Silicone greases best uses are as a lubricant for running wires through grommets and to seal electrical connections from the elements. A good example is the pin/plug connection for a headlamp. And remember that before you turn in these weapons for redeployment or transfer all the paint must be removed. instructions for removing the paint are in the TACOM messages. Have you seen Smitty? Not since he went in for a paint job the other day. h e e h e e h e e! that camo paint really works! silicone grease is handy to keep around your shop or motor pool. 787 40-41.indd All Pages 4/16/18 11:21 PM TACOM Maintenance Information (MI) message 15-002 gave instructions for camouflage painting M16 rifles and M4 carbines.

It should. Along with the operational checkout, the MITASs BITs (PBIT, IBIT, BORSGT, GRIPs) are the best way to ensure MITAS is working properly. And its easy to do: Power up the MITAS following the TM procedure and wait for the system to cool. It should cool within 15 minutes. The NOT CL indicator in the bottom right of the Gunners MITAS screen will disappear once the system is cool enough. PBIT was done automatically when the MITAS was powered up. PBIT checked the power distribution and the operational circuits needed to engage targets with the day sight. Select MENU-BIT-IBIT to run IBIT to check all FLIR operational circuits. Once the IBIT is finished, boresight MITAS by selecting BORSGT. This aligns the day sight and FLIR. Remember to close the sight door first and make sure there is no movement of the MITAS or turret during boresighting. Next select MENU-BIT-GRIPS and follow the instructions to test the gunner station hand grip controls. Accidentally hitting the wrong button during the GRIPS test produces an error icon. If MITAS fails the GRIPS test, test it again before calling in your 91S repairman. If the BITs ID any mission critical failures, youll see failure icons at the bottom of the MITAS display. Report them to your 91S. If it passes, youre good to go.

45 PS 787 JUN 18 if a bottle isnt fully seated and locked, youll get faults. And sometimes its difficult to identify whats causingthose faults. Sometimes it can take as long as 30 minutes for the test to run its course. Give the BIT time enough to do its job. if nothing shows up after 30 minutes, then report it. To install a bottle, pull the coupling back, connect the bottle and push the coupling forward to lock the bottle in place. Then give the bottle a little tug to make sure its secure. Also make sure the caps arent leaking. Sometimes they corrode and start leaking. At least every other week, open up the Stryker and run the A/C to dry up any moisture. That prevents a nasty case of mildew from forming. Moisture can also cause faults when youre ready to operate the chemical biological mass spectrometer (CBMS). Make sure the consumable bottles are seated and locked in place. Be pAtient when troubleshooting with BIT. Dont leave the Stryker shut up for long periods, especially in humid areas. Make them part of your Monday PMCS. Letting the systems operate will save lots of troubleshooting later. thats the only way they get fixed! Otherwise, the door handle can be damaged. before installing a training sample canister in the chemical vapor sampling system (CVSS), vacuum it. do all the suite system checks weekly. report problems on a DA Form 5988 or 2404. when opening the bottom of the rear door, make sure its handle is completely in the closed position before letting the door swing down.

Sorry pal, I couldnt find a kit to install the radio. Maybe next time. ok, youre ready to RoLl! Wait! I got a feeling somethings missing. How will I communicate with my team on the road? We hear you, Staff Sergeant. installation is difficult because there is leeway on both sides of the RT. You cant just put the RT in the mount and shove. That almost guarantees bent or broken connector pins. The only solution is slow and easy when installing the RT. Ease the RT into the mount until you feel the connectors meet. Then carefully push the connectors together. if the connectors arent lining up, reposition the RTand try again. if repositioning doesnt work, get help from your repairman. Guide rails, NSN 59 7 5-01-467-46 7 8, make mounting easier. The rails close the gap between the right side of the radio and the mount. But dont depend on them entirely. Even with the rails, the connectors are usually not perfectly aligned. Be aware that even when the RT is installed properly and locked down, vibration can cause it to shift enough that the RT loses its connection. if youve gone through rough country and the RTs not working, it may need to be reinstalled. if you need instructions for mounting the guide rails, email PS at: Just dont try to force the RT in place!

52 PS 787 JUN 18 The Tap Test 1. Tapping directly in the center of the plate will always result in a solid sound (three tinny thuds). The amount of surrounding material acts as a dampener, which prevents large amounts of resonance. 2. If you tap a plate directly on a label, you may also hear a solid sound (three tinny thuds). However, that doesnt mean the plate is delaminated because the curvature of the plate in this area also dampens the resonance. Note: The tap test should not be done on the ESAPIs sides. While tapping on the plate, listen for one of two sounds: Either a chime (three tinny chimes) or a thud(three dull thuds). When doing the tap test, rest the plate on the fingertips of your nondominant hand. A chime-like sound means the plate isnt delaminated. A thudding sound means the plate may be delaminated. When tapping a plate, if you hear three dull thuds, put that plate aside. Dont issue or use the plate because there may be delamination issues. Tap in the upper portion of the plate. there are two exceptions to this rule! Body Armor Because plate damage isnt always visible, do these two tests to help ensure your ESAPI is fit for the field: the Tap test and the tORqUe teSt. Hard armor inserts have saved the lives of many Soldiers in combat. But like any equipment, body armor needs to be inspectedbefore use. You can check your plates and conductsimple teststo ensure that your enhanced small arms protective inserts (ESAPI) are intact and will offer life-saving protection. Combat is tough enough, even when you have complete confidence in your body armor. Do regular inspections to make sure youre protected. Solution: Avoid tapping in these two areas. The tap test checks for delamination of the hard armor plates. Heres how to do it Bolt Metal pin Folding knife The tap test should be done in a quiet area so you can hear the taps.

Well, you guys dont have anything to fear because your Soldiers will use Method 20 to protect you from corrosion before they store you. Method 20 is the packing method that may use an application of corrosion preventive compound on equipment while in storage and when shipped. So, uh, how does the process work? Good to know we wont have anything to worry about when it comes to getting stored. And thats how your Soldiers will keep corrosion away. Ill sleep better now that I know about Method 20! First, the items about to be treated are cleaned and dried. a hH H After the items are treated, theyre tucked away in a wrap that conforms to MIL-PRF-121, Type I or II, and marked according to MIL-STD-129. Then the correct preventive compound is selected, perMIL-STD-20 7 3-1 (Standard Practice for Military Packaging) and applied to the item either by: dipping slushing flow coating spraying flushing fogging brushing Snug as a bug in a rug! 787 56-57.indd All Pages 4/17/18 1:37 PM For more on Method 20 and other corrosion prevention and packaging tips download the Packaging, Storage and Containerizations Centers (PSCC) Packaging Basics at: rfntb

58 PS 787 JUN 18 59 JUN 18 When the item is protected in a watervaporproof bag enclosure, desiccant should be strategically placed to avoid direct contact with the item. The bag will be heat-sealed to ensure moisture cant enter the watervaporproof bag enclosure. Activated desiccant means the desiccant is already working to absorb moisture in its vicinity. Dont expose desiccant to the environment when removed from their sealed storage container any longer than necessary. Removing the activated desiccant and inserting it into the unit pack should be the last action before sealing the bag or container. Add a greaseproof wrap to any items using contact preservatives that separate the desiccant from incompatible elements. Be sure to secure desiccant bags around the item and use humidity indicators for all packs containing desiccant. Never use damaged or frayed bags of desiccant or store them near lubes or oils. Dont remove desiccant bags from their container until youre ready to use them. Many high dollar items stored in long life reusable containers (LLRCs) may have desiccant information available on the LLRC data plate. Special packaging instructions will provide the information as well, if its available. The items TM can provide the amount of desiccant, too. Containerization Desiccant In Action if youre using Method 50 to fight corrosion, then youll be using moistureabsorbing desiccant. How much desiccant do I need to protect my equipment? That depends on the container youre using. Desiccant absorbs water vapor that tries to sneak through the barrier material during storage or shipping. I hope we can get past those bouncers! Those desiccants look pretty serious! Lets give it a try! Hey, Desi, are these guys on The list? theres always rustys place down the street I hear they let everybody in! While desiccant is definitely your ally, there are a few rules to keep in mind before you start packing 787 58-59.indd All Pages 4/17/18 1:42 PM
