- The frame on our 99 Kenworth cracked! So instead of replacing the whole rail we just put a section in and bolted and welded.... the guys did a great job... now time to add a few extras.

You nailed it, anything steel is not of the quality it once was.
The guys on the Pakistani Truck channel could fix that crack and have you back on the road in 2 days.
For sure. Those guys do some amazing repair work/fabrication with what tools and resources they have available to them.
The last one I fixed like that took 4 hours
And do the welding in their bare feet. LOL.
Also would repaint rig in phsycodelic colors.
Yeah they can new frame rails and all strip it down and back together n going
Knowing where to look and what to look for sometimes is a trick of the trade.
Now every little streak of rust might look like a crack.
You learn as you go though.....never stop learning 👍
For sure!!
nice of them to put that welding warning right where it cracks..... it's called customer service 🤣
frame cracks here decal.
Nice job 👍 thanks for your time to show us
They make an updated relocation mounting hanger bracket to prevent this from happening. The bracket bolts further up on the frame. Part # b111033
Really enjoined your presentation on the cracked frame issue, as a new subscriber i look forward to future post's, been in trucking since 78, your professional attitude is paramount .
That’s awesome !!! Thankyou for watching !!!
@@flintcreektransport where can i order a company t - Shirt , your Logo is par excellent. recently sent you a request on your web site. regards.
@@zionisimkills1098 I can shop you one for around $25 .... you can email me @ Justin@flintcreektransport.com with your info.
Not sure about state dot laws but, I have done hundreds of frame alterations that has included welding frame rails from pick up trucks to semi's and dump trucks. I don't see why there are a few negative comments about the welder or the repair. Its going to be just fine and will last the rest of the truck life.
I have done many frame stretchs and repairs like this over the year with no problems. The warning is because of litigation lawyers and people welding frames that dont know how to do it right
Andre Charron. I’d like to speak to you on this topic. Could I get your email address? I’m operating a mobile weld service and have a few questions!
Serious question about frame repair on a Volvo has rust hole after removing rust and preparing area getting a patch to fill missing metal then thinking of plating inside & out it's behind the fuel tanks overkill or should I do something different?
Except dot from experience if they see the weld he could be a real s.o.b hopefully they don't
I did my apprenticeship with Kenworth trucks Australia in the 1980s, they did a major recall, replacing cracked/ broken chassis rails, we changed quite a few. Even though the rail had a huge sticker saying “heat treated rail do not weld rail or drill flanges”, the engineers decided to drill a hole in the flange for the front spring hanger, new rails we didn’t redrill the flange, left the bolt out, never had a repeat problem! I’m surprised Kenworth are still drilling the flange against their own advice!
Oh wow !!!
It was on the bottom flange, the new rails didn’t have the hole drilled in the flange, so the bolt hole in the rear front spring hanger underneath the rail was left empty.
Correct
I've done two of these. If you don't sleeve them you will have problems in the future so good job. Also I sleeved the opposite side exactly as the side we repaired. I think that the frame structure should be balanced and also it will prevent this from happening on drivers side (which it will happen eventually)👍
By "sleeve", do you mean frame insert ? I've done many repairs like this and always put an insert on the inside because the metal has been stressed.
@@Last_of_my_breed yes exactly
Great job. Putting the plate on the inside is the right fix. Not depending on the side pressure on the bolts. I have repaired many Mack trucks old school in the 70s by doing the inside with inner frame rails. Weld and repair looks top notch.
Thankyou
looks like a solid repair but id do both sides then start putting inserts in your other kw's
Always learnin on this channel. Always.
Thank-you.
💪🏽👍🏽
That frame will never crack there in your's or the trucks lifetime. The double frame plate, bolted in, and the weld is more than sufficient. I know it's hard to weld the inside of the frame. But if it was, then I would probably grind the outside down smooth to pacify prying eyes.
Nice fixed!! Great welder!!!
Nice welding job!!!!
Shame on Kenworth. The repair job is top notch. The weld looks great and the fabricated channel on the inside is exactly what I would have done. That is the best way to reinforce a frame cracked like that. It will last a long time.
I had the same thing on my 1983 double wide COE. Also cracked at rear suspension where the torque rod attached to frame. Had them both fixed by a great shop in Miami 1990-91
Nice clean shop
Thanks 👍
I had my right frame rail snap right behind the cab right where cross rails where bolted. Was sitting just over 600,000 miles. But we did pull permitted overweight at times. I was sitting dead on 34,000 on my drives with 40,100 on spread axles. So you can guess I was hauling a big billet. Going around Atlanta getting on 75 north there are a few bumps on that ramp. I heard a bang and my whole cab leaned hard right. Fuel tank almost kissed the ground as I stopped. International put a whole new frame in it. I had them install trailer lift wedges. That help big time swapping trailers.
My W900L cracked in the exact same spot yesterday. I noticed it instantly bc it changed the angle of my steer wheel.
Nice finished product
What a beautiful truck
Excellent work.
Basically you put an insert. Damn looks good.
Cool stuff man 👍
Very nice fix.
And this is why I always to a pre-trip on the old trucks. Never *EVER* skip the pre-trip. I can hammer it off in 14 minutes flat, barely makes a dent in my hours of service. It's saved my ass even in my few WEEKS of driving a truck.
This happens newer ones as well its poor design a bolt in a flange zone where it shouldn't be.
Awesome weld. He’s got skills.
You can’t really tell if it’s a good weld but the looks of it. Anyone can stack dimes. It all comes down to penetration and settings
@@shortthrow50 I’ve been around welders all my life. I’d trust this
Good job! That's the correct way to fix them.. I have fixed a few now.. good ol w9's
Cool, thanks!
How much this repair cost?
Not the right way to fix them. Lots get done that way. Look for my earlier post I outlined the proper way. Welding the inside first is the proper way then the crack is 100% welded. The way they did it the crack still exists inside and can break again even with the fish plate
Pretty cool right next to the sticker telling you to disconnect the battery before you weld. Lol
I’ve caught frame crack and had welded and plated like you did but I decided to update those hanger brackets to ones that don’t use mount bolts in bottom lip of frame which tends to be a stronger fix.
Great job welder !!
nice job. That huge bead of weld will make it real easy for a dot inspector to spot
Yeap
There are places that are certified in semi truck frame work that even if the DOT see the weld with the paperwork you’ll be good to go
This types of cracks or even rust chassis are more common than we think as long as the work is done properly roads will be safe
@@brianugalde4713 i worry less about heavy trucks that have welded frames than i do idiots in small vehicles that are cobbled together with wire and tape and never get inspected ,,,i know several inspectors and they pay extra attention to a vehicle with a welded frame but they don't go out of their way to put them out of service any more than they would any other guy ,,only time i ever had issues with inspections was when i ran across an inspector that disliked me ,,and i had one that really didn't like me ,she was a commercial motor vehicle cop that lived in my town and really didn't like me because i beat her in court
@@wildcoyote34 I think there is no middle ground, cars or trucks, my point is that owners are not responsible for maintenance, my opinion was more towards trucks because it is what I do for a living and according my experience, not doing a good job the first time costs twice as much later, but I agree with everything you say about car owners who have dangerous vehicles on the road, about DOT l alway plead the fifth🤷♂️ 😂
Great work
Thnx !
Was involved in almost the exact same repair on LHS frame rail of a long hood freight liner classic except the crack other side of the spring hanger , I was adjusting clutch talking to driver when I noticed I could see him through the crack in the frame (he said wasn’t steering quite right on his last load😛)
Oh boy !!!!
fairly common issue with the w9 looks like they fixed it right. nice job 👍
KW Chassis are made of Med tensile grade 450 steel. Thats why they last. That break was due to a Hideous design fault...
Nice video dude hope you truck is repaired
Good stuff . subscribed 💪🏽💪🏽
job well done, wish i could weld like that
Good repair, now your driver's can be educated on what to look for... Safety first!!
Damn that sucks i had a buddy he had a w900 and he had the same exact problem on his. Same year too.
I think a new frames in order . But that repair will hold .
Just weld it up and put a piece of smaller frame on the inside of the frame and put few bolts through it.
Very well spoken.
My 2000 broke same place opposite side. Put similar repair in place no more trouble.
Sure is a beautiful truck man hope he fixed it up right.
Good job
Stick welding, somebody knows what they're doing! Way to go
Can't do that. Have to buy a frame rail. Its a major liability on the mechanic doing the job. Piss poor maintenance
If this was my truck I'd weld the crack grind it back then weld some diamonds shaped plates on either side to stop it from happening again
Fish plates won't last with the twist of the frame channel. But it will in a non structural part of the frame
That is correct. I saw that question on an ASE test once. The taper on the fishplate prevents an abrupt stress point, that a square cut plate would have.
@@tjon66 I weld broken frames back together. Welded from the inside first then grind the outside into the inside weld and weld the outside. No fish plates no frame glove and never have one break.
Nice job of Welding that Crack.
Thanks 👍
Lucky that wasn't a newer truck with the tempered steel frame. The weld would of weakened the frame.
Nice repair !
You can preheat the metal stops that from happening
I did same repair two days ago funny I found this
Good repair....
Thanks 👍
Cracked for a while?? that should be seen in a pre trip inspection
They are tricky to catch because it’s on the inside. It’s really hard to see
Its actually the Only design fault with those Older K-Waka's with those bolts drilled through that bottom chassis flange. I'm sure in that part of the Chassis flange Narrows to give Clearance for the Engine & Component traffic...
Bi*&ch please like your going to catch that. Shut your idiot mouth like you f'ing inspect your truck top to bottom every time you get in it. Idiot
@@duffelbagdustin9944 A trucker would, a steering wheel holder wouldn't
Maybe tuff to see i think. Truck builders fault i believe. Are petes REALLY as good as they think?
Right side is always getting its butt kicked. Nice job fixing it though. Keep up the good work!!!!!!
Thankyou !!
They all break right there.
Had this happen to me on a 73 Kenworth we just welded it diamond plated it on the outside no more problems
Great video and great work... all these expert comments lead to the question.. a year later did it holding up, rust out or crack again..
My Uncle says your welder, he's good. It would've been better if the area was sprayed with some boeshield .It's a product created by Boeing designed to prevent rust on airplanes. It's available in cans at Bass Pro Shops.
A large reason that cracked is the bolt through the flange, the horizontal part of the frame. The frame is a little like an I beam. When the top or bottom parts are compromised it weakens the frame far more than holes in the web, the vertical part of the frame. Looks more like the double framed it rather than just a plate.
Correct
Not uncommon, we have fixed a few.
That did not suddenly just happen.
You need to pay attention on your pre trip inspection, not just check the boxes.
Weld it and bolt a reinforcement inside it.
I've had 3 W900s crack like that. 1 is an 86 model the other 2 were 99s. One thing that folks do to prevent future problems is to use spring hangers from a KW cabover because they only bolt through the web, not the lower flange but they take the same shackle pins.
That was a big problem in 96 thru 2000
Kw I replaced a bunch under warranty
You guys should look into the new style paccar leaf hangers.
You would remove these weld the holes and drill and put the new ones on. This idea was dumb from kw
We just switched one out to airride front end. Stay tuned. Next week or the following I’ll be releasing the video
Flint Creek Transport i just put mine on air ride too. If you switch these hangers for the paccar ones. Itll sit a little bit lower too. Some shops that do air ride installs actually recommend the swap to prevent frame crack. cheers.
That’s awesome !!
Oh the long hood blues
Also be wary of new engine mounts Paccar is using , I’ve had three of my Red headed stepchild Cummins builds snap the right side mounts,
They brake all the time usually left side brakes first when I fix them I like to plate on inside with piece of frame and cut one flange off new ones have hangers like Pete with no bolt threw bottom
Last one I fixed was a pete. Broke in the same spot
I’m looking at a 2006 with a crack in the same place. I’m going through with trying to buy it because I have tons of friends who know how to properly fix it so it’s stronger and legal. I’m having them plate/reinforce the other side right away as well. No point fixing one side when both sides are known to crack.
Yes. That’s great !!! There are def a couple good fixes for the issue
Inside makes since. Because outside would screwup the frontend suspension geometry.
they make frame inserts for just such breaks ,they're made to fit behind the frame rails after welding up the break , you'll need a magnetic drill to drill the frame and its insert and bolt the inner frame to the original frame rail just saying
Junk frames still to this day, KW. The world's best led sled, lol
@@donniesmith9550 Dodge used to build the frames for both KW and Petes ,they may still do, problem being that most take their intended HiWay type rigs off road logging , dirt and other rough use , as those heavy duty double framed set ups are just so expensive with special order , wait and wait times before your new truck to be finished , and you start paying off the note with your 1st load . I think .Freight Liner which builds their own frames (the name alone says it all .....FREIGHT ... , are notorious for breaking and cracking the rails , when used in the rough , but you use what your wallet allows at the time or what the owner /boss puts you in , I had a 1976 , big orange Peter a long WB , former cement mixer that was just too damn long for some of the places I had to get in and out of , you could put a house between the cab and the 5th wheel , after a few aggravation filled jobs , both rails started cracking just ahead of the fron drive spring hangers so I just ended up cutting the frame at those breaks and shortened the WB,welding things up like this guy did but added the inserts to be just to be double certain that it'd be safe no worries of any future breaks , Did a lot of boulder hauling too ,we're talking 3 / 4 rocks and you were loaded , drop one in your trailer and you got outside the cab before dropping another one i , they would damn sure Jarr your insides when one went into your trailer , definitely not a job for those pretty aluminum end dumps , but would test your frames for sure , also your rear spindles, if you were to refuse to haul out of fear of denting your wagon or bending you driver spindles , well you'd end up being on the no call,no haul list when you are a lease truck for a big outfit ....I really miss driving sometimes been retired since 2008 , however I do not miss the
OTR work , the regs and laws and other BS took all the fun out of a once great job , it blows my mind how some will get fired for just being early for a drop , ridiculous s**t like that , heartless dispatchers without so much as a clue to what a driver's day really encompasses , we all know thew sad story ...sorry for this long winded story
You can actually take a old frame rail. Chop it and sleeve it with that. Works better.
Ive done one of these before was the exact same crack on a kenworth same spot... I ended up putting a 1" thick bar 2" wide 16" long under the crack and under the shackle mount moved it down 1" been holding for years
Did sort of the same thing, ran a piece of 1/2" in x 2"x 12" on the lower flange inside. Welded the crack and the 1/2 plate on the inner flange and that was at least 5 years ago.
That happened to my t600. Bad design.. I swapped out the rear shackles and replaced them with the k100 cab over to remove the bolt in the middle that causes the crack
I subscribed to your channel it just seemed to call out to me grinnin
You don't need to worry! about the crack in the frame!! lol
I would have replaced the spring hanger with the new style.
how the driver's leg doing the one who tires blew from flooded ky
Doing well !!!
I got same problem LW-900 lube truck was 3 years the dealers send welder from paccar seattle fix frame.they know about design for long why is not change right.thank video.
Same thing happened to my kenworth ,
Paid 1600 and got it reinforced
fish plating great job
Thanks 👍
That frame is T1 steel. You didn't say what they welded it with but if it wasn't 11018 rod using stringer beads only that can fail badly. The fish plate should've been diamond shaped, not square and welded to the inside. The crack should've been grooved out to an open root allowing your weld to penetrate into the backer. Then it should've sat 48 hours after welding to be magnafluxed to ensure you don't have hydrogen fracturing.
Flitch plate, I tried a fish plate once and the shop smelled for days!
It’s actually a sleeve that fits in there
Kenworth suspension problems Kenworth brackets problems putting peterbilt brackets before the problems
When we ran all R model Macks to do one frame rail replacement in our shop on a tandem tractor was about 40 hours work for one good man, and one good helper.
The dumps with the double frames we're usually the ones needing frame rail replacements though. Damn rust jacking between the inner and outer frame rails usually. Those were the ones that turned into lots more than 40 hours.
Very good, but that bead really stands out ?? Good to go now.
Because of the flex you need to plate the driver side also
Interesting..... Most times it’s just the passenger side ... we will be keeping a close eye on it
@@flintcreektransport but now that the passenger side is reinforced the weaker side is more likely to break. Its odd that if that is such a common issue they dont reinforce that area from the factory.
@@Bendigo1 Yea.... I hope not.... we fixed one before and it seems to be holding up well !!!
@@flintcreektransport that seems like that should be a recall issue on paccar. That is an engineering issue. Too much weight not enough frame.
@@Bendigo1 i wish !!
Awesome how much did it cost to do that repair
Cracked for a while ?🤔. Seems like I remember having to do a pre trip inspection every morning back in the day.
The tricky thing with these Kenworth is they crack and you don’t actually catch it because it’s a very small crack that u can barely see on the bottom side. Then one day it splits …….
Common problem with 8 bags suspension KW frames. My 2001 T600 cracked same area on left side.
Yes it is
I have a hair line crack in my frame, 2001 Petebilt 379, the cracked went through but not seprated, Is the back plate welded and bolted in or just bolted in?
Bolted. You can weld. But the vest is change the style of hanger
Shit my T800 at work sees miles and miles of rough Maine roads both asphalt and woods roads and it's an 06 and the frame is solid as hell.
Bring the truck over here so I can remove a spring hanger or 2 so you can see what lies beneath it. I’ll change your opinion for ya
@@shortthrow50 only springs on my T800 are the front ones...I run air ride...I also pressure wash my truck once a week
Did you see that factory sticker about welding right beside the cracked frame just to the right of the crack ! Looks like they were expecting a problem in that area. Great repair job, better than it was when Kenworth built it.
Negative. Every single truck ever built has this sticker. You not supposed to weld on the frame (you can drill it though) because that softens up the metal. Small low heat tack welds to mount a hanger stud would be OK, but any major welding has always been discouraged.
Can anyone tell my why mack has a three frame rail set up on their older trucks? Do they still make that set up?
You can order any truck with double and triple frames, think heavy haul and Canadian logging
Did they put a extra plate on the other side too? Just in case. Since it's a common problem on these frames...
Yes
I had kw do same thing a 1999 I had it fixed never had any problem
Pure yunk
Any reason not to grind weld on outside
Definitely can be fixed by a competent welder
so how much would this job run? i need to find a shop who can do this. i have a pretty bad rust area that needs a new section.
Depends on the fix 3-5k
Inside plate is called a doubler.Im suprised they stick welded it and didnt use a dual shield wire.
Done with the right rod and a quality weld is equal or better than a dual sheld
