Lots of men who had experience in World War II and in the Korean operation found out that their best buddy was their 01' Ml rifle . And ihat Ml remained their best buddy as long as they gave it the best ever-lovin' core they could ... with cleaning, lubing, adjusting, and protecting from the weather. Sleeping with your rifle was never punishment - it

was the only safe thing to do, to protect your "buddy" so he cou ld take care of you when things busted loose. Plenty other men found that their best buddy was their machine gun, tank, artillery piece,

truck, dozer or whatever. They kept their maintenance tip-top

because they knew that for the showdown on ly their equipme nt stood between them and disaster.

Even Your Tank Gets

The Needle With The New-

That's right, there's a lot of similarity be· tween the new fuel injection systems used on the Continental AOI, AOSI, A VI and A VSI engines and the hypo the medic used on you. O'course, the needle is screwed into the incake manifold of the engine, permanenc like, in. stead of stabbed ineo you. But the idea is the same. \Vhuffor this? Well, it seems that by using fuel injection they can solve some of the prob· lems that have been plaguing these engines, and get better performance· outa them.

One look at your Ord 7 will tell you which of these disks belongs (0 your vehicle. The third column in the table tells you how much base separation you can have. To measure this separation, take a straightedge and slip it between the rub· ber and disk where they're separating. From the rim of the disk, measure in. If L::==~~~~~~~~~..!!!i~ the measurement you get is more than the allowable amount given in the table, rep lace the road wheel, so it can be reclaimed and pu t back into good condition.

LlnLE JOE ... A HOT POINT Even "Old lucifer" would sweat inside a tank turret on a hoc summer day. So, consider how Little Joe must feelcooped up in that hot engine compartment, chuggio' away to keep up a supply of juice. Joe's built so that with proper care he'll charge like a trooper .. . even when you may think your armor plate's wilt· ing from the heat. All around his carcass are air channels and duns. \Vhen he's working full tilt, cooling air goes whistling through and around him like a pint-sized hurricane.

If you moke sure all hi5 panels and hole covers are in place and aren't . bent or damaged, that air will do its cooling job c lot better.

As in other engines, ail in Unle Joe plays a big (ooling role, So naturally, he has to have the right Ot at the right level, Especially in hot weather, it's a good Idea to double-check these items: Right oil level and weight; dean and serviced oil filter (see your LO).

Those panels and covers are designed to chonnel the air ni>w-if they're oul of whack, the cooling action's reduced.

I

A couple of other things to (heck to make sure the oir's doing its job-keep the air deaner dean; tighten the air intake (on nections; cieon the

fans(feen;

Here are some other possible hot spots to look for: Make sure your vehicle's heat exchonger ond air heater ore OFF ond not throwing hot oir bock into the engine compartment; see if there are any loose electrical cables or connections that might be throwing on extra load on the generator;

and make sure Joe's spark plug

isn't ""ked, dirty, or badly gOPfled. 54

You say you've'got a couple of dam. aged places on your M9Al protective mask facepicce? And yo u' re going to turn it in for a new one? OK, then ... turn it in, but don't get pencil -happy and try to pinpoint de· fects by marking up the facepiece. Just tag the part with DA Form 9·8 1 (Exchange Part or Unit Identification Tag) giving all the particulars, and turn it in. Using ballpoint pens, pencils, grease penci ls, paint and stamps on facepieces is strictly NO GO . That stuff can sometimes ca use more damage th an the defects. If you think the hole's too sma ll and might be missed when the mask 's being repaired, just stick a small piece of masking fape over it.

T he decon problem that heads all gripes is the ha rdening of slurry within the pipes. So the important thing in handling slu rry is to flush out the stuff-and in a hurry! These arc JUSt different words to the same old tunc-flus h ou t your decon after you have slu rry in it. That slurry ca n cause you a lot of trouble. Once it hardens inside YOllr dccon it' ll clog th e pipes and about the on ly thing you can do is to rep lace them. So remember ... next time you use your decon, remember to flush it Out good ... right away .. .'cause the slurry sets fast. Use lots of water and keep running it th rough your rig until it comes out nice and clear-no more milky- looking water. 55

More Tha n Ammo Might Make Noise Around ..

Your 90-mm AA Gun You can get a real bang oucta clean ing the 90mm AA gun. But it sure won't be the kind you expect- not if you do the cleaning with solvent.

When you get to slopping oround with the solvents,some of its fumes may get into the regulotors or power control units, which isn't bod until a spark pops from the synchronizer ringo rsynchrobrushes. Aspark ... and WHAM-you may have on explosion. This con be rea l bod in the regulator 'couse the window may blowout. Supposin' somebody is looking head-on at the regulator she blows?

Handle With Care Unless you know TM 9-36 1 like the back of your trigger finger, ic'll pay to look it over now and again if you wanna keep your M51 Skysweeper in shape.

YOUR FLYING TARGETS

Salt water's no good for any1x>dy's innards-yours or your RCAT's. Here's the word on giving that engine on your RCA T some areificial respiration and first aid should it get dunked in the salty drink. This is what you do right fast, jf there'll be any delay before taking it back to the shop.

Then remove the spark plugs and dean 'em wilh IOlvenl, fSN 6850-285-801110MI .r • Ic.hol, fSN 6810-191 -1627 (Chern).

Set 'em aside on a dean doth to dry .

Next, if you have fresh water handy Rush the engine thoroughly and drain it again. Pull it through several rimes while you're Rushing jt. Then put the drain plugs back in the engine and fuel tank, pour a gallon of alcohol into the fuel tank , open the needle valve wide and pull the engine through until you have alcohol running out the exhaust pores. Y'see, alcohol mixes with water, so it'll suck Out any drops that may be hiding in the engine. 58

Now open your mag neco and see jf je got wet. If ie did , you can rinse it o ut with alcohol, too. Then g ive it eime to d ry. Yo ur mag neto coi ls are waterproof a ll rig ht, but you can 't run ie wi th water in the poin t assemblies.

INSPECTION NOTE Dear Editor, Both in the shop and on the sites, we found that we were having a lot of duplicated effort in inspecting the king-pin lock nuts on our M33 FCS trailers and bogies that have been removed from Nike-Ajax trailers. Now any inspector checking these king-pins chalks or paincs a little note "King-pin lubricated and inspectecLdate" and his initials on the inspection hole cover. So, the next man along knows just when and by whom it was done. W'c goc the idea from the stencils on railroad freight ca rs. Ellwood W. Hagen Fort Niagara, N. Y.

CLEAN CAN CARRIER Dea r Editor, Here at FOr[ Rucker our Combined Battalion pulls motor stables in a gravel parking lot. On windy days we found that the blowing dust would stick to our oil measures , and so get into our crankcase oil.

Our drivers take the (orrier and the oil (on down into the areo, ond keep the meosuring cons inside away from the dust, except when Ihey ore actually adding oil 10 their vehicles.

So, we built this little (orrier out of mop steel I'/.-in sheet).

This has cut down on the dust a whole lot, and care in keeping the oil can wiped dean before pouring takes care of the rest of ie, CWO Delbert W. Robert. Fort Rucker, Alabama (Ed 1Jole-A1Jd

Dcar Editor, Here's an engine mou nt we have in our RCAT repair tent. As you can see, we set a sa lvage propellor flange into the bench top. and then welded a cross bar to the cheek of an unserviceable crankshaft.

MWO Ord G1-W110 (5 Nov 57),

Don'f get all shook up because your TB Ord numbers jump from 699 to 1000. You're not missing any- not right now, anyway. Page 235 of DA Pamphlet 310-4 (November 1957) clues you.

which has to do with replacing the fueltank filler-tube c911ar bolts on most of

your tracked vehicles, is marked urgent. It seems that the old collar bolts let fuel leak out, causing a fire hazard. The fix wire- locks th e collar bolts, so there's no leakage. This MWO is an Ordnance job, so why not give th em a call and see if your tracker is scheduled.

You might pass the word that the M289 rocket launcher for the Honest John missile needs four urgent MWO's.

They're MWO D065-W14, W19, W22 You know what to ask for and who

and W23. Your support unit does the work.

gives it to you when your Nike-Ajax missile equipment says to use MIL-l-4343A? The stuff for you is Grease, aircraft, Mll-l-4343A, Amendment 1, dated 1 Sept 1954. FsN 9150-269-8255 is worth a l ·lb can. Your supporting depot can get it for you from the Air Force through a Military Interdepartmenta l Purchase Request-MIPR for short.

You ' re right. There's no battery artillery mechanic in an Honest John outfit. Organizational maintenance is done by a guy called a heavy rocket crewman. He has a 147 MOS and his jobs are listed in Changes 4 to AR 611-201.

Don't do it! Ne ver! Never run your M59 armored infantry vehicle without its engine compartment access panels in position. In the first p la ce, you can get a fatal dose of carbon monoxide if a leak sprouts in the exhaust system. And second, your power plant' II overheat because the panels are pori of the cooling system. Paste this in the back of your head and anyplace else that's handy. It could save your life.
