I love how you solved the "O" ring problem. That 20 inch bicycle inner tube was a great idea. These trucks seem like a lot of fun to work on. They are not overly complicated like a modern car is what I meant.
+NelsonStudios you're welcome. So I watched this video just to see a 5 Ton video as I want one and have for some 5 or so years now. After you replied I figured I'd see if I could find out where you are and what your tour entails. Low and behold, your only a couple hours from me. I'm up in Helena. I work for Navajo and drive from Salt Lake to Helena 2-3 times a week and I run through Dillon, Twin Bridges and Whitehall. I don't like going to Butte cause hills sucks when you're hauling 105,000 pounds. Anyway, maybe I'll be able to get my daughters down there and take a tour with you. I'm new to MT and would love to see some more of it, especially in a 5 Ton.
Great video, we bought a Harbor Freight 1” impact wrench makes life a lot easier, with high volume hose. Wow, yours came off easy. We are doing tires that have been on 20+ years & fighting all the way nothing easy. Good luck - hope all is good for you & your business! Thanks
You can buy spools of red silicone o-ring in 3/8 on Amazon and cut to length then super glue the end together. You can also get in about any thickness you want if you want to over size a bit.
15:47 That technical level you mentioned is measured in increments of "ugga duggas" lol. Keep in mind that a 2 foot breaker bar and a hundred pounds of force is 200 lb/ft, an easy way to torque things "to spec" without a torque wrench. Thanks for sharing!
You are good man Charlie Brown, sorry, Mr. This is a great teaching video, I had not realize the split rim was on these vehicle. Thank you for sharing.
Les Schwab has the correct O rings for that rim. You have to push the parts guy to take the time to look it up in his book. The Les Schwab in Fife WA can get them for you. My friend gets them from there all the time. Any of their stores should be able to get them, if they will look. I have had them tell me they can't get them, but they can. I wire brush the complete inner rim area and then prime and paint it. Then I lube the O ring with "personal lubricant", which is water base. My tires also have the "run flats" in them. I used a sledge hammer & a couple of 2x4's to break the tires loose from the rim. I found it much easier on my back to put the tire & rim over an old semi tire rim to disassemble and reassemble them. No problems getting them back together and no leaks. I bought a 600' lb torque wrench also. My friend just uses a 3' breaker bar and a 6' piece of pipe over the end to break the nuts loose and tighten them.
If you need gaskets or orings you should contact Dooley Gasket. Not sure where your located but they are local to me in Broomall Pa. Get with Steve with the size you need.
I now use waterproof boat trailer wheel barring grease in place of the anti-seize. The grease of the anti-seize will wash away leaving only the aluminum or copper behind the waterproof grease will stay putt long term. Thanks for the video.
Interesting idea. Do you find the grease lets you over torque? I suppose the anti-seize would do that too and I mean c'on, is it possible to over torque these really?
Thanks for this video as I got to wondering what do you guys do when you get a flat tire. Kind of surprised you used a ratchet and air gun to remove the nuts....thought you'd use the air gun on both sets. Before becoming a truck driver, work at a produce company having to pull tires off of trucks/trailers for flat repairs. But we only had 1 piece rims and thanks for the info about split rims as I've never worked with 'em.Everyone loves seeing these things in action, but fail to realize what's needed when (not if) you get a flat out in the middle of no where.
Is the reason you are leaking air is because you gouged the metal bead seating surface in multiple spots on the inner mating surface of the wheel with that pickaxe ? Giant scratches ?
I heard of some tire balancing/ sealing fluid for big tires .maybe this would work in this situation. at any rate what this guy did worked. what more can you ask for?
you might check with Stewart & Stevenson in Houston for the part. They have a huge division where they rebuild military vehicles and I'm certain they have a parts department, Hopefully your seal works, but just in case, keep them in mind..
On your rims to fight the rust use chassis saver we use it on all our farm tractor rims especially the ones that have calcium chloride in them don't use por15 it doesn't last as long plus the chassis saver works great on anything not exposed to the sun. If it is exposed to the sun paint over it with different paint
I bought an M925A1 that had 14.00R20's on it. But I wanted 16.00R20's on it, so I bought a whole set. It took me like 3 days, working all day long to get them all changed. I couldn't stand those 16.00 tires up. I figured out I needed to lay them on an 8 foot 2x4 while I was mounting them on the rim, so that when I was done, I could use the 2x4 as a lever to help me stand the things up. ha ha My rims were the kind that had the round rubber seal squeezed between the two halves of the rim.
I have a 923 with the duels, obtained my truck about the same time you obtained yours. With these duels I'm basically stuck in 4" of snow. Too many tires to the weight ratio of the truck. Other than that I never had any tire issues with my tires.. Now that you've had these trucks for 10 years or more, working the singles in your opinion, are they worth it? Do you have any problems in the snow?
@@gmcxm211 in general I think they are just so heavy your not going to get enough floatation from the single to make any real difference. If snow is your goal I have seen tire chains all the way around turn them into tanks. That might be an option. All around yeah, I would say singles have enough advantages to keep an eye out for a set.
@@acme663ryo Thanks Its not going to happen this winter, matter of fact I don't drive it in the winter unless I have to, I don't go off roading in it as these are basically semi's with front wheel drive. My truck I got with a "new" title zero miles. everything on it was replaced. except for the axles and cab. rebuilt engine, new transmission, wiring, air brake system new cargo box with new troop seats and canvas. The only thing I use it for is for parades and static displays for some occasions. IT kills me seeing people drive these like these were humvees or something. Watching people completely submerging these trucks, you have to wonder how many of these trucks now are sitting around completely seized up with rust? Or my favorite is the Steel Solders rallies and these guys take these on those trail rides. You wonder how many had to be low boy home after that?
that would be a DIE not a tap.if you are getting carbon steel dies get 2 or 3. they will wear out and become dull fast. HSSdies are more money but last longer. good caution on removing the valve stem.i for one had not realized that...
Are you familiar with Ospho?....your rims are a little corroded....the Ospho will turn the rust into carbon....wire wheel it off.....then reapply....smooth by sanding or wire brush....try Bondo to smooth the area where the seal fits.....make sure the area is absolutely dry.....epoxy to seal......
I don't have CTIS on any of mine. It sounds like a very useful thing that operates on a bunch of easy to break, expensive and difficult to find parts. You have my sympathies on dealing with the 1600's. I look at those trucks and think to myself, man now that is something that would be real cool to use in the mountains but operating costs with the 939's are bad enough, I can't imagine what it would be for them. ...and turning it around but oh would it be cool.
Very cool work. Really interesting to see how that all went together. Can I ask what kind of work that you do that not having a military truck on the road costs you money? :o
+Adam Drumonde I am a history teacher but we run an off-road tour company in Montana in the summer. It has been a lot of work but going into year three we hope to have all our startup investment back out of it. It was a huge bummer when the motor in one of the trucks up and crapped out on us and I had to buy another to be the backup for the back up. If I find the time I hope to rebuild the motor and sell a truck, get back down to just the two.
I did 2 in one afternoon on my truck, by the time I was done I could not flip the tire over any more. Had to ask my wife to help me stand it up the last time.
I really like your videos about your M923. So far I had a lot of similar problems and your videos always helped out a lot - mostly when you again get to a point where you ask yourself "is this really working like that?!" :-) Anyway I have the same problem with tyres losing air - some more some less. How are you self-made gaskets working today? Did you find another solution to fix that problem?
Wow what a prompt reply :-) Sorry for the stupid question but what diameter did you use with the neoprene rubbers? I only found 1/4" gaskets for 20" rims to seal between tyre and rim. But not in between the rim halfs
+NelsonStudios oh thats cool, I thought these were just hobby trucks that you took out off roading!. love those big tires tho, just gotta be equipped well to work on them.
Hi, Now that is interesting, I live in Canada, Calgary, Alberta to be exact, and I'm totally interested in taking a tour, can you email me your site at: jpmalette@yahoo.ca. I'm in the process of setting up / looking into a tour of the train museum in Elly, and this would be on my way South, I dearly love Montana THE BIG SKY, I go to Las Vegas often and travel Interstate 15 all the way. By the way as an Canadian ~Armed forces retiree, I really love your video on Military trucks.
I find it just outright Amusing how my Father Tells me we "should" have someone replace the tires on my Farmall cub & Then I see guys like Nelson Replacing there own Military truck tires... & I feel like, If they can do that which is 5x more dangerous than an old farm tractor I, Can & should do them myself. how hard can it be? it's not like an M35 With Split rim!
No tire is dangerous until you put air in so just air down before and use a clip on to air up. You might find that getting ag tires to break loose from the rim is a more daunting task than I faced.
The hardware store guys *used* to know enough to help out the newbies, but these days they're getting retired off, and the kids don't always know... A *tap* is used to cut or repair female threads, and a *die* is used to cut or repair male threads, such as what are exposed on the studs. An old mechanic's tip to reduce rusting in the future - use some white lithium grease, or better a moly-D (molybdenum di-sulfide containing grease) on the studs when you put the lugs back on. As I watched a bit more, I saw that you are using an anti-seize compound. I'm not a fan of using a mattock or the like to beat on a rim - you can do a lot of damage that way, especially if you are not experienced. Generally, a few love taps to break things loose is the order of the day - if you need more than that, you might just want to take the wheel to someone who has the tools... I've seen a few guys beat on the wheels - like I said, I'm personally not a fan...
+Calup Jensen You can buy them surplus on rims cheap, $300ish per tire right now. God help us all 10 years from now when the surplus tires are used up/too old to run.
Sorry but rubber on rubber won't seal. Just as you seen if you accidentally double gasket an oil filter (rubber on rubber) you'll have an oil leak same principle apples here.
I got tired of remembering to drag a hose out and fill it every other week or so. Tires like those you never want to let sit low or flat. Wipes the side walls out.
"Damn Tight" gotta love it, reminds me of the harder 70's M52A2 tire changes with the deadly Split Ring. Good Video.
I love how you solved the "O" ring problem. That 20 inch bicycle inner tube was a great idea. These trucks seem like a lot of fun to work on. They are not overly complicated like a modern car is what I meant.
They are dumb simple to work on but also prone to strange issues.
This is an awesome video. I hope you're business is still open and healthy in this economy.

If you cut that bike inner-tube on the edge lengthwise, you can turn it inside out and it's all smooth on the inside. No more ridges to deal with.

Is the reason you are leaking air is because you gouged the metal bead seating surface in multiple spots on the inner mating surface of the wheel with that pickaxe ? Giant scratches ?
You did not show us you had it jacked up first, I was almost wondering if something bad was going to happen . . .
love that you use instructables. thanks much great video

Very good, I was think also adding a bead of fresh silicone to help seal your homemade silicone ring, Jut my thought...
+blinko656 It was an interesting idea making those and worth remembering but I have had only a 2 in 7 success rate with them.
if you stop to think... as you stretch your rubber o ring it becomes smaller diameter so adding a innertube is a brilliant idea.

LaRell Don't give up those rims. Mine are the ones where the gasket slips between and is held by air pressure, they always leak.
Epoxy coat the rim, fill it sand it smooth, fill it again.
Use a comealong wrapped around tire if it needs help sealing the bead.

"I don't know how water gets in there" proceeds to dump soapy water on the tire and let it sit for half an hour
haha I'm just kidding
For 5 year I was the army maint. Manager for this fleet of trucks. I help rewrite all of the maint. Manual before the army started selling them

Thx. So the O-ring's diameter is really 20"? Thought it is a bit smaller...
What is your business that uses these kind of trucks?

what jack you use
its pretty thick stuff .
Can get a "Bead breaker" Makes short work of it.
Several told me that and I have just a Harbor Freight breaker, like a big slide hammer and it has worked great.
WOW,,,, JOB WELL DONE SIR,,,, HATS OFF TO YOU,,,,
Great repair, Like the video
y dont you apoxy primer it after cleaning it up no more rust
+Calup Jensen I have tried redular primer but never the epoxy stuff. Is there much of a difference?
+NelsonStudios o yes the epoxy seals much better smother. tuffer.just clean rust of really good spray it sand it spray agian sand till pits filled
I might have to give that a try then. How long is the dry time?
+NelsonStudios o id do over night
+NelsonStudios if still a little soft should hurt as long as stiff enough not to smere
good video thanks for sharing.

in tyre service shop 15 min and 18 us dollar/wheel........in hungary........
Very TIREing. Haha get it, okay no.
Yea ok, maybe that joke needs to be retired....
what jack you use
+Haralabos Lukatos A 20T air over hydro but for the most part the air is a gimmick and I never use it. Just a good 20T pump jack will do the job fine.
thank you for your answer. You have nice truck.
