I believe there will be zero Torque on the Carrier bearing. That is why it is called the Carrier bearing. It just makes up for a difference in elevation. All your torque should be at the output shaft from the transmission and the input shaft to the rear end. Or i could be way off!
100 % correct sir
That mail will see almost zero torque, that's not the problem, the lateral forces are the problem
Joe Cummings what lateral forces. It's a driveshaft. If it's balanced it won't have any lateral forces. You really think the paper thin career bearing metal housing that the rubber is vulcanized to would hold any kind of forces in the first place.
Ya know, if'n it were my $dollar ... I'd do it 100% my way too.
my mom would say it more like : 'mosses' dollar, 'mosses' way ... nuff said
Thanks for the vijit...
@@Mad.Man.Marine that should have read radial Force,. And yes there is plenty of it whenever the universal joint is running out of angle . No, that carrier bearing is not made out of paper thin steel. I have some on my shelf and a few in my used driveshaft pile that I can measure, but just off the top of my head they are at least 1/8 inch

great job guys ,I think the bracket holding the carrier bearing might need a little beefing up ,maybe a cross member
I agree, the twist forces could be problematic.
Obviously, there are other reasons, but I wish my Dad was still around. He did this stuff for a living, and would have most of the answers for you. Been trying to recall some of the stuff, but it's been some 30 plus years now. Grey matter ain't what it used to be.
You guys need to add gussets to that carrier bear mount. To prevent it breaking side to side. It will have a lot of force on it. God bless
Think about that Tom welded to a pice if 3/8 steel bracket 1/8 and rubber what gives first 🤷♂️
I would be more worried about harmonics than breaking. I however do agree, that thing needs bracing.
@@DirtPerfect this is true. However my thought is if during a turn off road. The drive shaft gets in an awackard position. It may max out the rubber. Then you could have breakage. The rubber is there primarily for taking out vibration. Just a thought buddy. Your truck your call. God bless
Yeah I agree, those things see a lot of side Force, or maybe I should say lateral Force. On a hard pull they're trying to move side to side, up and down, or any combination of those directions.
That little stub cantilevered off the center of that tube is going to be a real weak point. Not to mention when there are up or down forces that cross tube is going to flex in torsion.
Not trying to criticize you because it looks like you're doing really nice work, just giving you my opinion as a guy who has built a lot of these things
I am an Engineer and I agree additional bracing is needed. There is no downside to adding bracing. Space permitting, brace it side to side.
is it just me or every time you are under the truck DP always drop something lol
Im not one to judge people and their work. But i would think with the amount of torque a diesel motor has that yaw woulda put a bracket from frame rail to frame rail above the carrier bearing bracket. Just wondering
0 applied to that part
@@DirtPerfect
It does
Mike, if you get a chance could you explain how the drop axle works, when to use it, when not to use it, etc. We don't have them in Australia and you've stirred my interest! Great content, keep it coming
Yes thanks
@@DirtPerfect lmao
John hall we do have them in Australia

MEASURE TO THE RIM TIRES MAY NOT BE BALANCED AND OUT A 1/4 OF AND INCH I WORKED WITH 11R225 FOR OVER 25 YEARS AND HAVE SEEN IT A MILLION TIMES
Sure hope you going to put more brackets on that carrier bearing cuz as is a lot of torque right there
Think about that
Some people think the prop shift bends left and right and up and down it doesn't hence universal joints each end do all the work the prop is just spinning the bracket holds the weight of prop only
Wouldn't a couple gussets be a good idea on that carrier bearing bracket it looks like it could twist off under heavy load ?
Why think about it’s job
Listening to you guys argue cracks me up and makes these videos even more entertaining great job guys the old truck is looking great.
"Appalachian engineering" at it's finest, thanks for sparing us the details
👍👍🇳🇱
nice to see two friends build something beautiful together and have a lot of fun with it too.
TOP man.
thanks again for the video Aaron and Mike
Good work as always some squares from fireballtool.com/ might have helped your fab work MBTS might use them more than DP unless Lt Dan builds become habit forming! Looks good weld it !
Now that you’ve read 180 plus ways you did it wrong I’ll tell you what I would have done. 😉
On a serious note I would have run a cross member between the frame rails to hang the carrier bearing from and instead of having the lift axle positioned lower with the square tubing running across the bottom of the frame I would have run the tubing parallel under the frame rails but made another cross member to span the frame rails at the front of the lift axle mount incorporating the square tubing.
This would allow more room around that lift axle making it easier for MBTS to work there. (Maybe I just like Aaron more than you. 😉)
Plus you need a cross member or 2 in that area that you stretched anyhow.
I still can’t believe so many people “think” that carrier bearing will apply torque to that bracket.
🤣😂🤣😂
Shouldn't the carrier bracket be braced side to side to eliminate vibration?
I'm no expert but I was thinking the same thing. I think it needs a bracket that goes rail to rail instead of straight out like it is. I hope the current bracket is just a place holder till they get all the fabricobbleing done.
The driveshaft was only lengthened and properly balanced, the rear end wasn't moved, the truck transmission wasn't moved, the pinion angle didn't change.... so where will the vibration you are talking about come from? Please explain
0 concerns about that
@@DirtPerfect ok I understand
If your planning on putting a dump body and actually working that truck. I would not think twice about double framing it from the back of front spring Hangers atleast to the front of tandems. I'd go all the way to the end where dump pivot is. Built several tractor conversion dumps with trash truck rears that are 60,000lb rubber suspension. The twisting and torque on rails and point pressure at the front of dump body are incredible. Just my opinion. Seen quite a few broken rails.
I think the carrier bearing mount is more then strong enough! There should be no bind or pressure on it. A gusset wouldn’t hurt I guess but it would be over kill. This truck is going to be bad ass! Can’t wait to see it done!
I love what you guys did on the carrier bearing, one thing i would do ? Weld some gussets on that 2x2 pecker sticking out there, that's a lot of weight and vibration that will be going on right there , Just saying ... Be Safe, See Ya
Enjoyed the video. I read the comments before hand and thought the fabrication must be a disaster and MBTS must be worshiping demons. I didn't find the comments to fairly reflect the work or Aaron. Maybe time to relax and cut the guys some slack, it's their time, money and effort going into your entertainment.
Sucks working in tight spots with lots of stuff in the way doesn't it?!!!! I build aluminum boats from scratch for a living and man oh man. The worst part is right before the deck top goes down. All the longitudinal and deck stringers are in the way. Constantly stepping(tripping) over them sucks. Then there is all the welding to be done in ,around, and on everything. It's hard work and can really make for a crappy day sometimes!!! Keep it up man. She's lookin boss.
If you want to see how the geometry works with the bigger tires on, just fix the rear drive axle in place and move the tires from the rear drive axle to the drop axle and that should give you a pretty close to neutral unloaded state. :-)
The only thing I see that would concern me is the bracket holding the carrier bearing. Won’t that have a lot of torque on that stub, with no side to side bracing? Asking for a friend.
Think about that
I think there will be some torque on the carrier bearing but as they increases with the axles not lining up, that means that when the axles gets loaded that will straighten up the two axles and the torque from the two axles not being perfectly straight should diminish too. Unloaded there will be more torque than when loaded but also a shorter timespan of that torque being applied, as you run out of revs and shifts gear so I don't think it will be a problem.
@@DirtPerfect If there is enough torque to move/bend that square tubing holding the carrier bearing, the driveshaft flew out already or there was a bad wreck. A piece of square tubing that short is incredibly strong. Also just look a the mount bolts sizes for the carrier bearing. They would break long before the tubing flexed. In normal operation there should be very little load on the carrier bearing. Most of the load is just the mass of the driveline it self. I threw one on an old Mack loaded 64K and used a small come along to pull it back up and get home with no issues.
@@Dingbat217 a bearing is a bearing, it doesn't load any torque and most likely will never see any due to the pinion angles being within tolerance, as long as the pinion angle on the front driveshaft beyond the carrier bearing matches the pinion angle on the rear driveshaft, there should be no issues. Conversely a drive doesn't have to be exactly inline with any transmission as long as the front and rear pinion angles are equal and within tolerance, that's the job for the universal joint. No where is it more important to address pinion angles than with a race car when it sees a lot of torque and speed when launching, the rear end will try to point itself downward thus changing the pinion angle, that is why they use a 4 link to prevent that from happening. They only lengthened a driveshaft, they never changed any angles. If it worked before it should work again.
The truck will never go 140 miles per hr going off road. The welding on the carrier bearing should hold about 60,000 lbs of shear force, the carrier bearing will never see that amount of torque, if it does, you have a bigger problem with binding that goes well beyond the driveshaft and most likely will never work at all even from a standing start, from where I'm sitting, I see no issues.
@@DirtPerfect Not worried about the twisting force, as you say, the bearing handles that nicely, however, the lever forces and vibrations from the suspension moving up and down might, over time, cause issues and cause fatigue problems on that extension. I believe that is where some gussets would help support that extension. They certainly wouldn't hurt.
Day late, but if would help, that looks like the exact pusher axle that's on the kw t880 I day every day. My pusher always looks like the main bags are a extended a bit far, but as that's the way they are set from factory. If need a pic or 2 on how mine was setup, lemme know.
I think if I were you guys I would cut two 1/4 inch triangle reinforcements along side your carrier bearing extension. Just in case in some of your adventures you might put some twisting forces in there. Not saying there ever would be.
You were asking about tires- think about how much information the military went thru before they decided on which tires they put on this truck- bet they spent more time an money on that that you have spent on whole truck-just saying cause I spent 27 years in military an saw their process on making little decisions
Ok so technically if you saved thousand dollars on driveshafts that's a thousand towards a RV. Lol
Lol no
I’ve drove so many loaded triaxles off road and the excavation company used to stock drive lines on a shelf (cuz they has so many trucks ) all I ever saw was the tubing would rip apart . I mean yeah once in awhile a Carrier bearing would go bad but most of the time when a truck got stuck a guy would dump the clutch and rip the tube . One time I saw the weld on the tube cracked and no one could figure out why the truck wouldn’t move till they sat there and watched the tube spin on the yoke . If you think of it like a fuse the tube is the Weakest link
Trucks lookin awesome guys i hope I'm wrong but I think you need a piece of that 2x2 across under carrier bearing I just hate to see ya torque it up and tear it out just my thoughts still awesome are the wheels gonna be Shiney aluminum ◇
Think you should of double plated you air bag extension. So bolt to axle and bag. So if make a change, no cutting needed to remove then can cut center box tbg. Between plates to make finale. And could still just unbolt it make another change even latter!
Soon there will be dirt and mud and the pretty shiny undercarriage will be dirty. I did always wonder what those wheels some trucks have that don't touch the ground were for. I assume they are used when you are carrying excessive weight too much for just two rear axles?
I like the main shaft placement down the center. Like you said... How is the truck going to know it's not hooked to the same spot it was attached to? Just beef up that mounting bracket. BTW: Any clamps still have the pad that always pop off? LMAO
I would of soooo over complicated that for myself. I would of tried to find a third axel like what are already on it and tried to figure out how to make it driven and liftable. Probably can't but I would of tried. hhahah
Would the truck, because it's army over engineered, not carry the 20 tons you want to carry without the third axle? The third axle is just to pass road regs. So all it needs to do is look as though it's carrying weight, to look legal. do you need to get it tested to get road legal?
MBTS dream modify truck at DP's expense. 🤣
Did Aaron weld the front & back of that tee holding the carrier bearing? It looked like he missed that, but the shot was dark so hard to tell. Everything else looks great!
Didnt the man Scott? say the blue cap in the short shaft was supposed to go toward the front of the truck? He said the blue cap kept stuff from getting into the short shaft when you're running. Did you get that right or maybe the camera angle screwed me up?
I can see the carrier bearing fly out over time .just saying time will tell
If it does you will know
@@DirtPerfect LOL If it does, you will be the first to know .. you'll be getting a call from Captn' Kleeman, he'll be stuck up to the door handles in mud with 150 ton of rock in the dump box and 8 flat tires. I had to get that one in..lol
I would of hang that bearing off a cross member all you need is a 6" channel and a couple flat plate to make one.tall tire on the pusher would of help with your angle on the bags . Keep moving forward
You worried about frame twist flexing those box tubes into cracking? I was thinking on recommending some triangle corner bracing on the cross members and the carrier bearing mount tube just for good measure?
Another awesome video, looking forward to seeing the finished truck.
looks to me like the hardest part of the entire job is going to be getting the old girl out of the shop...
For those commenting on that bracket I believe DP has taken care of that by the use of a turboencabulator.
The original machine had a base plate of prefabulated amulite, surmounted by a malleable logarithmic casing in such a way that the two main spurving bearings were in a direct line with the panametric fan. The latter consisted simply of six hydrocoptic marzlevanes, so fitted to the ambifacient lunar waneshaft that side fumbling was effectively prevented. The main winding was of the normal lotus-o-deltoid type placed in panendermic semi-boloid slots in the stator, every seventh conductor being connected by a nonreversible tremmie pipe to the differential girdlespring on the "up" end of the grammeters
😂😂
After much research and comparisons, I have to fully agree with your synopsis!
Lol
Damn, you must be a politician? lol
@@machinemoverman4614 no I'm not a politician but it's not my place to tell him how to build his truck.
Awesome build! Any plans to put some gussets on the center support bearing bracket?
Love to watch this pair. Glad I'm not the only one with ten thumbs that go crazy.
Guess what, engineers know these things too but what you're not aware of is that engineers are controlled by management and an almost universal management dictate is to design things as cheap as possible, so closing in voids is not something that most engineering managers are willing to pay for and they fall by the wayside at that point due to management and not by engineering.
Top job geweldig gedaan 💥💪👍✊ Groetjes uit Holland 👋🏼✊
I'd probably put another bar on the other side of the carrier barring and connect them. Incase it twists from torque
Man, so many factors involved! Good job, guys!
Always turn your tape measure so you're measuring the same way from both ends, i.e. if the tip of the tape is against the frame rail on one side you should use the tip against the frame on the other side
Backseat Welder / Problem finder -- I`d suggest the Center bearing should have a 5/8 - 3/4 thick 90 degree gusset with a 7 to 12 taper using the idler bolt when that gets torquing it`s gonna ask for 200 % of each of those back axles pushing and pulling , it probably won`t turn it off more or less try to push it side to side ,You do have an angle on the little drive shaft I gather -Looks good otherwise .
Why think about how that works
Man has chains, Speed-Binders, and come-alongs! What does he do to move an Axle, his puts his back into! If he is not feeling it yet, he is going to be sore in the morning! Remember, Mike, no complaints about your back hurting! 😊😊😊
That is a true craftsman and what a professional. Scott really is the man!!!
In my day you drop a tool it cost a quarter with inflation it would be $1.50 now.
Love the sticker on Aaron’s welding helmet. One of my favorite sayings. 🤣
Was thinking you can drop the axil and then you said I can drop the axil.
Good morning DP and Aron. Hopefully you all had a great weekend. So it's time to knotch up the game on the monster truck 😅😅😅. Watching from Jamaica 🇯🇲
Thanks buddy
@@DirtPerfect looking great so far
What, MBTS does not have any welding magnets?
Don't forget to tighten up ALL THE BOLTS..........
My opinion, and I don't claim to be an expert, but the torgue on the center bearing is going to twist that bracket right off. Not when they are in a relative straight line, but when you get articulation, that short shaft becomes a lever.
Was just going to post exactly the same thing.
Lol think about that guys there is no torque there this is one thing I know a lot about
@@DirtPerfect I hope you are right, but I don't think so.
Should be no torque on bracket because of the bearing I believe
I think you are right. Not from torque but a linear fulcrum because the short shaft is pushing from the drivers side to the middle. But it's an easy fix to add a tube on the backside to change that T bracket to an H bracket. Nice catch!
Yep DP and MBTS using their masters degrees in redneck engineering. 👍
DP and Man Behind The Scenes Lt Dan sure is looking awesome so far
I’m concerned about the carrier bearing bracket not being wide enough for it like it needs to be wider that’s just me if I’m wrong I do apologize Mike. Y’all are doing fine job on the drop axle installation. Hope y’all have a Blessed One Sir.
Thanks and have no concerns about that
You might of got lucky by just calling one of the 6x6 bone yards for a cross member but I am sure you built one by now....... 😎 Reserved thoughts on the carrier bearing mount, usually mount to a cross member.
Stay tuned
Mike, I hope y'all have a video of Officer Hoover doing the final inspection. Love the build and the channel God bless y'all from south carolina viewer
Thanks and he does
Never criticize a man until you walk a mile in his shoes. Think about that. Now think about working for a huge corporation like GM or Cat that's only interest is making money. Now is it fair to blame all your dislike and cut corners on engineers? They are given their marching orders and have to do what the boss man says. There are plenty of contractor, builders, operators, etc. that do just enough to get their check and move on to the next job leaving a mess for the next guy. I'm glad to see you take pride in your work and don't do that. I take pride in my work as well and try to engineer the best I can with the many constraints given to me by the man. I don't think all contractor, builders, operators do half ass work just because I've been burned by a few. Wish you wouldn't rant about engineers when your real issues are corporations and a few bad engineers.
Have worked in that world and understand the comment but no excuse for some
If the product that hit the road or job-sites
Some wonder how Lt. Dan will exit the building. Can't you just pick up the back end with your crane and rotate it around, instead of doing a 278 point turn?
We all want to see the 40 min in time lapse of him shifting it a 1/8 of an inch at a time
Capt. Kleman would be the first to know if it’s going to let go he can do it
Good old boys just having fun and getting shit done !!! Love it 😊
Hi guys does it need a cross member mind you it must be on the road now best wishes phill from England 🏴
Thanks watch the next video in the playlist thanks
How does the carrying capacity of the single tires on the Army truck compare to carrying capacity of standard truck dual wheel?
Same
Cant say I noticed in the various video's, but did you treat the new metal in the chassis legs for corrosion before welding it??? As I was just thinking that any moisture between the two "C" channels is going to be a perfect breeding ground for rust..
Thanks and core 10
Great job guys. Congratulations to MBTS on 6k and one question for ya. Did that angle guage come outa ur gokart front end alignment box? 😀
😁
You should have just brought an m917 dump truck from the military it would already have the bid on it plus the lift axle and it six wheel drive too
Not what I wanted way different truck
I love that MBTS says "eyeballs" to warn you every time he strikes an arc!!!!
Anyone catch mbts sticker on welding hood?
..now, that is heavy duty, good job, looks great, stay safe,,
Really enjoying this type of video. Like your others but this is a weirdly attractive project.
Thanks
Hi Mike, what are your plans for the front in, and mean the cattle guard? If it was me I beef it up and put your logo on it and build and better radiator grill protection. Just to give you some Ideals.
Thanks not for sure yet
Good work on the driveshaft the truck is looking better every video seen it painted in the live feed looks good when is the truck bed going on
I'm not sure you have the air bag placement correct. My thought is that when the tag it fully up the air bag need to be fully compressed. That way when you air the bags up they extend to support the tag axle. Just thinking out loud here from what I saw as you were testing the travel. The drive shaft looks great and should be out of the way when the tag is raised.
Covered that
Hello there. That trades person made a dam good job of that drive shaft. It was good to watch a guy apply his trade like that and with good youmer. We like people who you can have the crack with.
Thanks
Everyone on about the carrier bearing should go take a look under there truck. There always hung with some stamped sheet metal. It won’t fail unless he runs the drive shaft it into a stump or big ass rock.
Exactly thanks buddy
Good too se pro working keep up the projob thumbs up 😷😷👍👍
Question, would it make a difference to add a piece of steel (same size as the crossmember) underneath the main frame between the two crossmembers for support? You would then have a rectangular crossmember, make sense?
Stay tuned
Everything's look go to me. except the carrier bearing support . I thought is that the drive shaft while turning it is trying to become out of center in all direction. But this will work till it don't
Thanks but not possible
You would have done better putting another cross member for carrier bearing. The torque on it is awful and will snap your mount under load. All the twist at rear axle goes into that bearing.
It’s on one

Take it to the bank, Mister Michael, by this time tomorrow your phone is going to go crazy; between OSHA wanting you to produce a series of "This ain't the way to center heavy stuff up" videos, the national Chiropractic association asking you to become their poster boy and a ton of tool and equipment companies offering to bring you a truckload of their latest lift gear.
By the way, MBTS can verify this but OSHA is NOT a little town in West Virginia.
Yup, that's petty. Lol
