- IN THIS VIDEO WE START WORKING ON THIS PETERBILT 349. THE FRAME IS TOO SHORT FOR IT'S INTENDED USE. WE NEED TO REMOVE EVERYTING OFF OF THE FRAME FROM THE CAB BACK. IT ALSO HAS AN ISSUE WITH THE CLUTCH. SO WE NEED TO PULL THE TRANSMISSION AND REPLACE THAT AS WELL. WE NEED TO INSPECT EVERYTHING AS WE DISASSEMBLE AND ORDER ANY REPAIR PARTS. WE GET THE TRUCK STRIPPED DOWN START FORMING THE PLAN FOR THE STRETCH. HOPE YOU ENJOY!!
The amount of rust y’all have to deal with amazes me. I bought an 79 international F1954 factory double frame dump truck in the late 80’s and sold it in the early 2000’s and the frame looked like new still. In Texas off road in the mud and sand zero bad rust. That salt is bad stuff on your roads.
I watch your builds for one reason. INTEGRITY ! You are an inspiration to always do it right, and I do not even build trucks. This information can be transferred to any job. Thanks J. C. you are one of the best!
JC is a rare breed of man that we rarely get to see anymore. NO cutting corners and cheaping out! He knows what he wants the end product to be and he builds to that standard!
There are many ways to cut and splice a truck frame. The 45 degree cut seams to be a industry engineering best practice as far as I know. You have a big project on your hands. And yes it’s an absolute that the frame needs a glove to double it for strength. To take stress of any weld joints. 👍look good so far once it’s stripped so the full picture of the current frame conditions are no longer hidden.
JCS, I really admire your integrity and concern for the highest quality and safety of your builds. Sadly you're not a commercial shop! So there are too many guys out there building sloppy and dangerous installations on commercial vehicles that we all share the highways with. I couldn't believe how bad that other truck was that also belongs to your friend! Thanks for showing the right way!
I like watching these type of videos. I learn a lot from you JC even though I will never do anything like this but I just really enjoy fabrication videos!
I’m glad the guy came to you. Paying for knowledge will be rewarding. It’s unfortunate he had the other truck done wrong but getting it right will be good.
100% truth ! My thoughts as well.
I don’t know how this channel appeared, but I’m hooked. Love watching & listening to great explanations. Also good editing. Thanks for the content.
i dont know what or how you got here but we are happy to have you.
I was just wondering about that truck today! Glad he’s choosing the right path with you… can’t wait to see you tear into the other one
Always a pleasure to hang around people who do it right, or dont do it at all.
Glad your friend is rethinking his truckand that you decided to support him.
Our FAVORITE DIY show on YT, not even close…!
You sir are a true craftsman and don’t mind getting dirty👍
What a beauty! Excited to see the JC touch.
That’s a big project to take on. Plus all that rust doesn’t help things. Looking forward to the build series.👍
from what I have seen [watching him work] he always has a very good reason for what he does, and how he does it.
Man that salt really takes its toll. I tend to agree with your engineering and I am sure it will get the 4 layer of paint treatment too. When complete it will last a considerable amount of time, unlike the deathtrap. Keep the content coming.
Friendship trumps all. Good on all of you. Y'all stay warm and dry and safe.
Wow ! Excellent video !!!
All of your assessments and options presented are logically thought out and make complete sense.
Structurally, you have covered everything and the throw out bearing issue was a bonus reason for removing the transmission ... gaining more needed access. Looking forward to the next part of this video. It's always refreshing to watch and listen to a skilled person with considerable experience in their comfort zone. Your clearly are the right man for this job. Respect.
I think you have a good plan. I've seen several 30ton, and 75ton wreckers doubled frame that way. Add the cut off and add the additional frame from front to rear. I'm sure you'll do a great job.
Great Video J.C. Lot of work a lot, Thanks for sharing this with us.. Always watching 👍👍
Your wife Is and absolute treasure!!!!!
Jc there are several heavy truck shops and salvage places here in central ms that may have what you need. I don’t have a way to transport parts but can help a little on lining stuff up. It might be worth spending a day or two on the road to significantly cut the wait time down.
i picked up some sections today. fingers crossed they look good once i strip them down.
I like how you break down the how and why of the work that you're doing.
So glad to see 'The Rest of the Story" !
Cheers
Do you get to keep the pieces/parts that you take off that the owner can't use? If so, good stuff for other projects or repairs. I've commented on this before but it can NEVER be spoken too much about and that is the amazing support that you get from your partner and precious wife! I see only a few on TH-cam that this happens. She is an absolute jewel of a woman! Not only supports what you do but gets in there and helps!
In 90s i worked @Peterbilt in test dept. One truck i was working on had rear alignment issues, turns out a frame rail needed replaced. To see the frame assembly guys unbolt & pull out rail then slide replacement in while truck parked right outside the back door, was pretty damn cool.
that is what needed done to this. would have made a much cleaner end result
JC thanks for sharing your adventures, I enjoy watching what you are doing!!!! 🤗🤗🤗
I so glad you stuck to your guns, It'll be nice to see it done Right! Great Video!
I’ve been air hammering the frame of my 2003 f-250. This road salt does an absolute terrible number on the steel. So many parts needed replaced, but I just keep telling myself when it’s done, and it’s done right, it’s gonna be great.
first i am so glad your friend has decided to go with you doing the tank conversion that other rig was a disaster looking for a place to occur thank you for everyone who wont know out there on the road that the truck your making replaced a rolling accident
You are so through and knowledge I once called you the Johnathan W of trucks love your videos
i remember that.
Love watching your vids. I miss doing this kind of work
I love these frame stretch projects!
30:19 most weld per bond is a sinusoidal line. It's actually what they used to do when they build battleships. They didn't know how powerful welds would be (as a bonding method with that metal), so they have "teeth" at every join, which describe a sinusoidal line. One meter of welds is actually something like 4 stretched out.
Great video J.C.Smith it's a nice project. Looking forward to the next video on this truck stay safe Mr & Mrs J.C.Smith.
I like your idea of bringing in a piece to ..... running out of words here .... I am so darn sick that I can barely hold my head up
so sorry to hear that. hope you feel better soon.
Ive done alot of what your doing and its alot of work ive fixed meny tri axel trucks with dubble frame horable seperate them like you and that liner
I’m hanging along for the ride JC. you got a lot of work ahead of you and I like the way you’re thinking this out by servicing the clutch kit while everything is out makes perfect sense. Looking forward to this build.
Life would be next to impossible without your telehandler JC. 😮
NAH. just have to be a little more resourceful. where there is a will there is a way.
Glad he choose a better truck to put that tank on , plus it’ll be done right with no cutting corners to just get it on the road .
this is getting a different tank.
Love that style of truck.
Time wise I think you are going to be forced into doing a frame splice Parts wise this is going to be expensive. You will do a great job on this project but it will be time consuming. Thanks for taking us along! Tom
i can only spare so much time. picked up frame sections today. the splice starts tomorrow.
Mr Jc Hope all is well. Tell your grandson hello. Thanks for sharing and stay safe
thanks mr. hal. his name is memphis and he loves watching you all.
Looks like it will be straight forward from here!
JC I learn so much from your videos thank you for sharing your videos.
Good luck my friend, that's a lot of work & fighting that rust is miserable. All are good options U spoke of. I myself would have shopped for a different truck, like a clean southern truck the proper length I needed. Thank U for posting.
if another truck was an option, that is what would have been done. i have 2 trucks that are perfect for this tank but i am not giving them away. this is the most cost effective option for him.
I've just found your Channel so I'm playing catch up but you ain't no fool & you know your Trade, good job mate 👍👍👍
welcome and thanks for watching!
Clicked on video, hit thumbs up, then started watching!!!!
how have have you been my friend? i certainly miss seeing your videos. i sure hope you and all of yours are doing well.
I was wondering when the needle gun would come out. Great tool for rust scale. I have one I use on my car hauler for maintenance.
Excited to follow along on this build!
Need the Jaws of Life or similar device to pop those rust jacked liners out.
Wow. What a job. But you are doing an excellent job as always
Love your channel. Always learn a lot.
You the Man Mr.J.C. love your work! Y'all take care.
Happy new year to the best camerawoman and interior expert on TH-cam!!!!! 😁
I eventually started to fix my cars (inspired by You, among others), so don't have much time to watch your movies just after release. Greetings from a mechanic from EU.
A friend will help get it done.
A good friend will tell you when you'r re doing it cheaply, dangerously and wrong. And then help you do it right. Good plan for the stretch frame, the original frame looks reinforceable. The inner and outer layers added will minimize the original frames multitude of bolt holes. Viable plan so far.
I’m glad your friend JC bite the bullet and took your advice on his truck’s. We all know he’s a good working man and and his income makes the decisions as in me as well. As all ways JC love your work. Cheers Steve 🍺🍺🍺. Sorry your wife’s work as well 🌹🌹🌹
Gonna be a big job no matter how you do it. I think a cut off would be a nice fit. Upgrades the wheel hubs, gives you a cleaner frame and could get a more favorable gear ratio if desired
he wants to re-use the original axles and suspension. i suggested walking beam or slipper spring in place of air bags due to the liquid surging but he refused.
@@j.c.smithprojects interesting feller that guy.
YES Another JC Smith project!! Thanks
What a beautiful truck! 🙂 Kinda hope he’s keeping the 20-inch Daytons 🤟🏼 Will be following this build like a bloodhound after a scent 😎
Did some auto cars back in the eighty’s double frame plus 1/2” plate down the outside of the rail were long wheel base built for the oil fields
Have you heard of alfab. In Columbus ohio. When I worked at Bradshaw we made tanker trucks and if we needed something like that. That is who we used. By the way I've never commented on anything but I like your work and channel. And if you have already thought of them sorry for wasting your time.
called but have not got a return call yet. your not wasting my time. happy to see you in the comments.
At least he got smart and brought it to you to do. The other shop probably would've just reused all that old worn out crap over again
I imagine you tried PG Adams for the rails, they shipped me a set of rails within a week of my ordering them. That was a year or so ago. They were really easy to work with, although I imagine a local shop may be able to offer better pricing.
yep. they were the most expensive. we have found a cost effective option.
Excited for a new build
Great video , can't wait for next one . 👍
Sooooo happy the guy decided to let you tear that death trap apart and do it right.
I noticed that you didn’t wear your dark glasses when using the plasma cutter. To me the “fire “ looks the same as the welder 👨🏭, what’s the difference in terms of eye damage from looking at the light from one versus the other.
i was using the torch. doesnt seem to bother me.
I think you’re on the right track. Gotta be strong. I would weld on a good used frame if you can find one.
I'd cut off as you pointed too doing.
That frame is toast. Even try'n find a used truck with a good frame? Or salvage yard for part of one? (Even a double frame?)
We used to install Grove & Mid-Equipment rollbacks. There was always long cutoff frame tails that were compatible. I remember 5 Int'l Cab n Chassis, jacked drivers forward to facilitate the cab to trunion for hoist n dump bodies. The cutoff parts were a treasure trove later on down the road. The boss even sold one of'em the frame parts to a competitor.
Back in the late 60s, a friend of mine had a 750 Ford double frame twin screw, we cut it, put 7' in it. He went to a local shop had them form the frame rails of thicker cold rolled material but to fit up with the outside dimensions. The vertical cuts were staggered, after I welded them in they were fish-plated. He got a factory driveshaft before cutting anything to ensure the right finish. These were all done in a rust belt state.
Be a shame to build off of the existing frame n have it fail on down the road. This'll make a nice piece when you get it completed. Anxious to see how you get there.
🇺🇸🏁🇺🇸 👍
I like that clutch jack.
JC, think-your best bet is long frame rails from the Junk yard, and definitely butt 2 rails per side. Perhaps, U can keep the existing rails to make it easier for the holes and alignment
Safety first.
Have seen a shop that extened frame labled no weld. Can be done if frame is heat treated correctly
P.G. Adams brake can brake 50 FEET of 1/2" grade 100 steel!
I would love to tour that place. Or at least see the brake at work !!
That would make some awesome content, if you were to go watch them make your rails.
That said, I'm sure they were the highest price.
I will also say, they ALWAYS hit whatever number I ask for.
Top quality!!
Where is Adams Brake located? I'd like to give them a call on a frame I'm planning to stretch as well.
What ever u do it will be a real good job.
My 1990 378 had adjustable crossmembers. This was a pleasant surprise when I decided to double frame the truck.
There is a chart online at Lmt tanks. It shows what wheelbase and the measurements of tank .that helps on setting it up for axle weight. The chart is called the tank wizard.
They make a water-proof wax like material you can apply as rust-proofing between frame rails to prevent future rust that won’t wash away.
Someone loves their blue tele-handler.
My hubby watches your videos. I have a 92 Freightliner cabover needs a lot of work and needs the frame stretched. We love in Cleveland.Ohio. Family in Canton. So we were excited to see you are close to us. Please let me know if you can do some work for us❤
i get contacted often from folks asking if i would work on their truck. i wish i could help everyone.. i appreciate that folks like yourself are willing to put their truck in my hands but i just cant. im not a repair facility. i am slow and like things a certain way. few people understand just how much time, effort and money it takes to build a truck the way i like to do it. most dont want to invest that much into repairs that they can have done at a repair shop for pennies on the dollar.
O-H-I-O Porter greetings!🇺🇸 Happy New Year! Frames are quite an interesting topic! I’m glad you’re doing this job…there’s plenty of things to cover here. All that rust buildup between the frame & liner can really cause problems! 😔 Some people don’t even worry about such things I guess. There are guys that have done a straight frame cut, weld the piece & then add the outer bracing…and they’re happy. I’ve heard several pros & cons. I think with all the rust involved it could use more area for the weld. So you’re gonna have an inner liner & an outer “L shaped” liner as well? That’s like having 3 rails then. Now that will take care of any issues. Good stuff! 🥰😳✌️
hello from the Netherlands .
thanks for the video JC .
Sincerely Hollandduck
It keeps amazing me how you can do all that work by yourself and the “valuable” help of Your wife. I’m Shute you’re lying to us. You probably have a crew of 5 to 7 people, and every time you are about to shoot a video you kindly ask them to live the shop. Kkkkk greetings from Brazil
no help just us 2. i dont work nearly as hard as my father or grandfather.,
It's also about European laws, where you can't modify stuff, and because internet, it ends up floating on your side of the pond as hearsay. There are some countries here where registering a modified frame (of any kind) that's not done by the manufacturer or an authorized dealer/shop is... well, might as well try to catch a lightning in a jar.
Enjoy your videos. When you double frame a truck could you not seal the edges all the way down on top and bottom with silicone and once per yr or every other yr just remove the old silicone and redo it to prevent that from rust jacking I'm double framing a peterbuilt starting Monday and trying to find away to slow the rust jacking down
i dont want to seal it up. i prefer it open so anything that gets between it can get out.
Great camera man
those needle scalers were built for that work mate, i use mine doing up car trailers
How do you protect against rust jacking in the future with a new inner or outer insert? Paint?
we have a very simple solution......it will be in the next video.
That's what I like about it, you do it right
Enjoyed the video J.C 🔧🔩 Interested to see what route you take. Hope you and Mrs.S are doing well 👍
I think you got a good plan sounds like option 1 is the best and option 3 is the fastest. It all depends on how you mount the tank but you can make it somewhat part of the frame. Check out Diller out of PA they build and mount a lot of manure tankers on trucks. Good stuff J.C.
JC with box trucks you have can you re use those frame rails to save time and money I did my 71 kenworth using a 4 spring int corporate clip and used mack frame for a liner just an idea
Hope it,s better be safe peace
Hi jc. Love the video you gave me some points that we did some right things on the frame stretch we've done ,1st the diagonal cut.2nd the overlap of the reinforced frame.( We've put 20" over from the cut-off are) i was also concerned of the strenght frame.(between streer axle and drive axle, where most of the load will be..(in which we cut the frame in between) and reinforced it with ¼ thick steel plates.(not frame cut outs)on the outside so as not to disturb the cross members.and one question. Will the welds weaken the frame "if" full welded? (The whole reinforcement, front till the end,about 7ft lenght.we done it at 6inches full w/ 4in gap in between)thanks i'm really learning a lot from you.
i would not add a plate and weld it the full length. the frame has to flex. i dont want a frame too rigid as it can crack.
Liner on the inside cross member you can adjust outside then you have to deal with spring hangars and suspension problem cause you are widening the hangars
hangers will accept an outer frame without issue.
@@j.c.smithprojects but you are widening the frame at least a1/4 in rail on each side =1/2 what about the bushings from hangar to rear to springs
@George think about what I mentioned measure measure measure George just wondering have you stretched any trucks tell me where I am wrong trying to learn
this suspension doesnt have bushings in the leaf springs like you may be thinking. they are in a moun ting bracket that bolts to the leaf spring. this mount is adjustable. the bushing and sleeve inside have enough room to accommodate without issues.
Who makes that clutch jack ? Never knew that existed. Work smarter not harder is my motto...
otc i believe.
Would reamoving the cab and engine transmission for a donor frame be a effective option
all the donor frames i find that are long enough have already been stretched. if one has to be stretched, i would rather not pay the price and do all the work for another chassis. i would rather stretch this one.
31:10 - I like the idea of a cut off from another truck with a smaller liner!
that is what is happening.
Have you though about putting the lift axle to the front side of the drives?
yes. if i put it there, it justb means the drives have to go farther back. i gain nothing. they have to be placed right for proper load distribution.
👍thanks for your hard work and sharing your knowledge 👍🤔you have used bus frames before with a cab swap and the price of steel 🤔
I might be thinking about it wrong but I think adding an L to the bottom would add more strength than adding one to the top. My reason for thinking that is the bottom chord of the frame is under tension with a load and the top chord has a compression load. If a frame rail fails from a heavy load being exerted down the bottom of the frame would tear and the top of the frame would only bend or buckle. I've seen frame rails that were broken on the top and down the side and the weight of the truck held it together. It went unnoticed until the truck was put on a lift and the front tires stayed on the ground with the rest of the truck in the air. What caused the frame to brake was the guy was plowing way to aggressively, went off the end of a parking lot and his plow dropped in a ditch. He pretty much started driving over his own plow.
i have never seen a manufacture put an over lay frame like what i am doing on the bottom instead of the top. i have owned 100's of trucks with an double or "overlay" frame done the way i did this one.
