he did a great job but I'd love to see this car driven until crank snaps, just to see how many kilometers it can do. Bearings might wear out because of rough surface though
This proves that Kiril is a serious welder, i expected it to give as soon as Vlad let the clutch up and the true turning forces came into play. I've seen it proved and am still stunned it worked!
I’ve watched an old school mechanic weld cylinder walls, blocks, drive shafts and gears with a coat hanger and torch. He would preheat until everything was red hot. Then use the hanger like a tig rod. He could “stack dimes” with it like a pro. It was amazing at some of stuff he done and made over the years.
@@quentagonthornton49 yeah, so google tells me most metal hangers are made of steel. Pretty sure the block is cast iron, so i think its about the percentage of the metal thats carbon. So then the hanger will have a lower melt temp than the block, if im understanding correctly
I tried this three times and failed each time. The break happened on the edge of the journal flush with the counterweight. I wasn't good enough of a welder to make a weld that would hold up to much more than the crankshaft's own weight. Just a tap on the workbench and it would break again. I'm impressed with what these guys did right here.
Now that we know you can weld a crank and it won't break.... Why not modify a crank to a crossplane and also do the same with the cam and see how it turns out?
@@Dr.Westside Sure there is. The cylinders would be firing at different times, so you'd need to modify the camshaft to suit that. rotate each cylinders lobes the same amount as their respective crank throws
@@Dr.Westside what, then, would *you* call a camshaft utilized in an engine with a crossplane crank? Obviously the cam has to be compatible with the crank.
I can’t thank you enough for translating to English! I’m glad I found this channel! Idk how long it takes to get merch over here to Michigan 🇺🇸 but I’m about to find out🤘
that tire bouncing acting like a jackhammer definitely put it through a rough time, if that did not break it then it is probably tough enough for that power level! i might not trust it with 400 HP and torque but in a normal engine i doubt it would easily break!
A small note here: Instead of iron, a closer translation would be cast iron. Pure, elemental iron is what "iron" means. Basically cold or hot rolled soft iron with almost no carbon. A small carbon content will create steel and the hardness will go up as you increase it. At around 0.7-1% carbon, you arrive at cast iron, a really hard and brittle type of iron that they are talking about. The reason it's hard to weld is complex but it's an infamous cast iron problem (it's case hardened, it will get carbon content gradients, the random heat will anneal or harden it in spots etc)
Excuse me for expressing meself in (sortof...)

The fact that it survived after such abuse is absolutely amazing. I would have thought that the heat treatment either from the factory or from the welder would have caused issues.
at the time of writing this comment I am at 0:04 in the video. I come from a partial engineering background (my dad was a mechanical engineer that worked on industrial plant and could really turn his hand to fixing things pretty handily, hed usually drag me along for the ride to learn things, i took to computers rather than mechanical) assuming that the weld lines up with the crankshaft (ie doesnt disrupt the weight/balance of the crank, or is kept within tolerance) this would work 100% judging by some of the comments, Garage54 have a top class welder. the theory is that if a weld is done properly, its tensile strength will be stronger than the material thats being welded
The key to welding iron is preheat preheat preheat . You can either use a 77 iron welding arc rod a 7018 , or 6011 All of which are suitable for welding gray iron . Your best bet is a 77 iron welding rod and a careful even preheat .
Fun fact, when Porsche were developing the flat 12 917 engine in the 1960's, they experimented with glueing the crankshaft togther, it was to get around a problem they had machining the central output gear.
as usual, kudos for the amount of time and effort you put into doing all of that to make a video. that is a lot of work and money just to show everyone
I wonder if a 7018 or 110 series rod would have been easier for them to have welded a crank with using an old school arc welder. I welded an old truck frame that broke that held out well so would an arc welder have welded a crank?
Because of his thoughtful preparations for the welding and balancing it properly.. It worked. Otherwise I think it would have easily failed. Good stuff
Yeah, even a billet crank can fail if not balanced at all, well with awful balance with everything or at least the other parts also like pistons and rods out the side of block. There was a youtuber built a small block chevy 383 , a 450hp proven blueprint and did really good too , it was all broke in, and the first time they put the gear selector in reverse, immediately snapped the crank clean in two pieces- the rotating assembly did not recieve any balancing what soever. They complained yet then learned their mistake.
That welder guy did excellent job. He is a master of welding. Even I think the Lada's crankshaft is a good material. I think that car is ready to cover the next 60.000 miles :D Russia forever! Salute from Hungary.
Hahaha!! That's amazing! I've seen only one other man weld up a broken crankshaft,That was my grandfather,He was an excellent welder. He did the crankshaft repair because my grandmother was angry at him for racing the car and breaking parts...He finally broke the crankshaft and didn't want my grandmother to know about another breakdown with the car. The engine ran for a year before the crankshaft broke again. Your youtube channel is a joy to watch!
In modding cranks for a stroker the machine shop will chop out your rod journals and re-weld them on wider for longer throw (longer stroke) but it goes to heat treatment once again because it is welded. Perhaps they anneal the crank first to make it softer to weld and correct bending Now I want to see that engine run on a cross-plane crank (cut up the cams to suit timing too) and do a tune and dyno for that too
Dear Garage54 If you're ever working with iron again in the future, you might want to try out "PostAlloy 50" welding rod. Make sure you preheat the item, weld her up with the postalloy 50 rod, and then let it cool slowly. You should be good to go. Thanks for another fun video! Catch you on the flip side.
I would like to see an inspection of all the main journals after this try. To see whether there is a visible wear on them due to the unfit tolerances. Could you make a follow-up video? And to make the video interesting, you could add some longer beforehand driving on your test track, with a proper beat-up to the engine, with high revs...
Good one there.Make a one cylinder Lada engine.Take out 3 piston/rod units.weld up the oil holes in the crank journals not used.leave all tappets and push rods in.See if it will run.
Awesome show you all. Great fun and hard work go hand in hand. we are all glad you spread your joy to the world with all the excitement of your interesting fun projects from your shop. Thank you soo much for sharing And you have great sense of style in your merchandise anyone would love it. We all wish we could be having all that fun with you. you bless god. bless you.
Great experiment. I've been told it's impossible but wondered if this possible. Yes it is. Of course I just need a machine shop and welding skills to do it.
How about making a driveshaft from various materials? Fill some pcv pipe with concrete, fortified of course. Or, maybe use things more elastic or that construction foam. Go from lightest strong material to heaviest, from elastic to rigid. Attachment of ends may be quite difficult, but I am sure you gentlemen are able to discover the solution for that. Cheers!
I just love the work you guys do. You have done almost all the crazy things i wanted to do and more. Now i don't have to. Thank you for that. Keep up the good work. By the way, that crank shaft is doomed, you forgot to drill a hole for lubrication oil.
The YT sign on the wall is bad-ass, and the car is pretty damn cool too, you guys have the start of a way wicked garage54 mural there, I hope you see-fit too finish it soon. great-job on the experiment guys, thanks for sharing.
I have also had a 1976 mustang II V6 HO that had a broken crankshaft and it ran perfectly except for a little bit of knocking. The crankshaft was broken at a 45° angle inside the center main bearing. So the front and back half were forced to turn together if another crank was split.
It can take weeks or even months for the mechanical tensions/stresses of a weld like that to normalize, probably rendering the crank out of alignment. Would be interesting to see if the proud Lada still works at that point. A fun experiment nonetheless. God, I miss my old Lada Niva.
How about next time you cut another crankshaft but offset it perhaps 180 degrees also offsetting the cam shaft to make it fire. Love watching your videos from Australia
you need to wickedly clean the crank and you want to stick weld it with hardened steel. welding distorts the crank so it has to be straightened before you chuck it in your lathe / grinding lathe.... no matter how well you weld and straighten and grind, you've still got your oil journals so 4 cycle cranks can not be welded but i used to weld 2 cycle outboard powerhead crankshafts
Over a short period of course it will work. But over the long run, the impurities in the welding material will begin to create internal fatigue which with a persistent cooling and heating of the engine, will crack over a long period of time. Making it a time bomb waiting to set off.
A friend of mine I used to work with hired me to remove his engine and have it rebuilt,then reinstall everything. ( I used to do mechanic work as a side gig). His truck was an 87 Ford F-150 with the 300 straight 6 cylinder. It still ran alright,smoked a little bit. Engine was kinda loud and clunky. Anyway I removed it and hauled it down to the Engine/Transmission/Machine shop to get rebuilt. The next day the shop called me and says the crankshaft was broken in half and it needed to be replaced. It cracked at an angle between one of the main bearing journals under the main cap. I went down to check it out. It was rocking back and forth in there for so long that it looked like it was perfectly machined like that. The bearing was shot. I really couldn't believe my eyes. Had the main bearing journal and main caps align bored. Replaced the crankshaft with a reconditioned one. He retired about 5 years ago and he was still driving that truck. I replaced the engine about 2006 or 07.
I think you should cut the crankshaft and camshaft in half. Then you can weld half of each shaft to mechanically change the timing on that half. Like 45° off, 90° off, and 180° off.
i've suggested welding a crank to so many people because i knew it could be done and work, especially on a small low power engine like that. Not surprised it worked but i am surprised that the youngman got it welded so well. I expected much worse
Seeing that chopped crank... whoa. To me, this is one of the most fascinating videos you have done. However, I think technical stuff might get as big of an audience?
Assuming because of location that even that small welder is 220v albeit with the wrong wire, but with a good person behind the trigger, got some pretty good penetration there. They were at least thoughtful enough to grind the faces to maximize this. The only side note, the Lada engines and mods are more likely to hold together being low HP (and low stress) on an already iron block engine.
I expected it t go boom on startup with cast iron being so brittle. But surprise surprise not only did it survive but it worked great and survived a hard test. I lot of it is alignment and the kid being a top welder. It would e perfectly apt with low horsepower applications. I reckon it would probably go for years.
You can cut and weld the crankshaft on a couple spots to change the firing order. You'll have to do the same for the cam which is going to be trickier but I'm sure you'll figure it out.
My wifes Crank pulley broke centrically around the center shaft, meaning it freely rotates while the center is still bolted in, somehow still have that pulley turning by pulling the alternator belt really tight which synched the pulley tight against it's insides, car shouldn't run in condition but it does. Already ordered a new pulley thou not expected to arrive until Christmas, had not luck finding a used one any where locally or on the net.
Mildly scary indeed lol. I've seen what kind of damage can broken piston rod do to an engine block. Almost cutting it in half. Would be interesting to see damage after crankshaft snapped. Though bearing caps should still hold, maybe the damage to the block wouldn't be as bad.
You could remake engine so every piston was firing at the same time,would be interesting to see.
+1
That would be crazy!
I WAS THINKING THE SAME THING!
They already did this on the russian channel.
good idea ! But I guess that will need a heavier flywheel
It's a testament that the kid is a good welder as well.
Ivan
He's really good, in my opinion.
he did a great job but I'd love to see this car driven until crank snaps, just to see how many kilometers it can do. Bearings might wear out because of rough surface though

Isnt that essentially brazing?
@@ootmaster1 Brazing is where the base metal isn't melted down, like soldering, but hotter.
@@amorag59 right, thats why im assuming was done in the OPs comment. wire hangers would melt at a lower temperature than the surrounding material

There's no such thing as a cross-plane cam .

Yeah, they're just way better at it than most. XD
Personally i love watching other people do crazy shit to their cars precisely so i don't have to xD
Next time, cut and turn the crankshaft and the camshaft 90°, making it a cross plane crank motor.
On second thought, the cam would need to be cut and turned 180° for the 90° crank to work (among other things).
Yeah, custom cam would be needed, but otherwise with the stock carb and swapping ignition leads it should work without any other mods.
This is the best and most intelligent idea 👍
Cam. must cut and weld too
@@jasonnoteboom4489 they have already demonstrate being able to easily make their own cams using simple methods in other videos.

The only side note, the Lada engines and mods are more likely to hold together being low HP (and low stress) on an already iron block engine.
I expected it t go boom on startup with cast iron being so brittle. But surprise surprise not only did it survive but it worked great and survived a hard test. I lot of it is alignment and the kid being a top welder. It would e perfectly apt with low horsepower applications. I reckon it would probably go for years.
Thank you for all the effort you put in to entertain us!
Make all pistons on the same timing. (All have same TDC at same time)
You can cut and weld the crankshaft on a couple spots to change the firing order. You'll have to do the same for the cam which is going to be trickier but I'm sure you'll figure it out.
Did anyone notice the tech poking his head past the door while vlad was showing the crank on the lathe 🤣🤣🤣
My wifes Crank pulley broke centrically around the center shaft, meaning it freely rotates while the center is still bolted in, somehow still have that pulley turning by pulling the alternator belt really tight which synched the pulley tight against it's insides, car shouldn't run in condition but it does. Already ordered a new pulley thou not expected to arrive until Christmas, had not luck finding a used one any where locally or on the net.
Welding and straightening cranks used to be common back in the day
I would think that you are much more likely to break a timing belt/chain than a welded crank. Awesome video guys!!
so nobody is gonna talk about that dude that shows up behind a door at 11:14 😂
What a great video and the welder is a TH-cam natural!
Inquiring minds: Can you weld a crank?
Garage54: Yes!
14:07 Need to know what those modifications are¡¡¡. Amazing video anyway and some practical knowledge while having fun
Mildly scary indeed lol. I've seen what kind of damage can broken piston rod do to an engine block. Almost cutting it in half. Would be interesting to see damage after crankshaft snapped. Though bearing caps should still hold, maybe the damage to the block wouldn't be as bad.
