Yes, this channel does some pretty fun (and labor intensive) exploration which is quite cool. The contents of the oil pan looked like what we saw in my friends Chevy Vega when we removed it back in the late 70's when the engine seized. Lol!! The Vega had an aluminum block with cooling and cylinder block hardened layer coating issues (just like in this video sort of) and was not ready for prime time.
@user-vp1sc7tt4m My uncle had an old Vega in the 90s when I was little. I'm not sure about the year. But I learned how to work on cars with it. He had it sitting in his yard for years. He said they were problematic, and I didn't know what he meant at the time. But great memories.
Absolutely. Now I'm left wondering if in F1 style, they left larger clearances cold but pre-heated the engine/coolant/oil to operating temps before starting. This might actually work... wait... elongation of the crankshaft, never mind.
Maybe spinning a soft crank inside soft bearings with close tolerences caused pickup between the two. Would removing the bearings and having a crank machined oversize but with more tolerence & thick oil avoid it? Or perhaps roller bearings on the crank mains (a bit expensive on a lada but)

"Aluminum's thermal expansion coefficient is roughly three times higher than steel" So the clearances also needs to be tripled for this to start working. Wish they could retest with that
Its coated with ceramic and it’s duralamine , so the thermal expansion is roughly twice that of steel Duralamine also has a better thermal conductivity so it dissipates heat more efficiently the engine is less noisy because of lower density of duralamine which results in better vibration dampening properties
Yes! I thought about that. You could have made the comment less nerdy saying "aluminium expands much more with heat than steel, that's why it got wrong with a worm engine"
Metal, ceramic coating and sleeves don't work for bearing journals. Think about the forces working on it. It's like an English wheel, stretching the surface till it fails. Even case hardening will fail. I used to repair shafts and pumps.
You know, just the fact they were able to machine an entire fully functional billet aluminum crankshaft with a lathe and a mill, and not one single piece of cnc equipment in site, is absolutely incredible.
Some race engines have used forged aluminum crankshafts, but the crankshaft is lined with a hard bearing to reduce wear and expansion. The issue with this setup is now that the crankshaft is lighter, its not balancing out the reciprocation of the pistons so there will be greater vibrations, the original iron crankshafts were tuned to balance out the pistons. Still, another great experiment from you guys!
It's a bit less important on an I4, as the primary is balanced, but the secondary balance will suffer. Small displacement motor... Meh. It's not going to matter as much as you'd think.

Congratulations! You just discovered the critical flaw of the Chevy Vega's 2.3L I-4. Mind you, the failure was partially because of a minor miscalculation of thermal expansion... but still very-much the same results from application of the same method: Coating aluminum with an anti-wear treatment versus employing iron parts in an effort to save weight, which--ultimately--didn't work. On further speculation: Perhaps if methods of cooling the oil were applied, along with a larger oil capacity, this might've endured better... if it's dimensions were first calculated to take heat expansion into consideration properly. Also: Perhaps the employment of custom aluminum connecting rods--like used in professional drag race engines--would help lessen the impact of the compression & firing pulses on the journals. And any improvements made the oiling system in terms of volume of delivery... to help in control thermal expansion... might not hurt, either.
@@russriley3005 if they get the clearances and oil viscosity right it probably would work just fine as long as they warm the engine up fully before putting heavy load on it.
I was thinking that as well, undersize the journal a couple thousandths. But as others said in the comments here it would probably start knocking with too much clearance. But an increase in the viscosity of the oil could counter that.
@@youtubasoarus the aluminum expands and contracts at a different rate as the coating that is embedded into the crank. it will separate throwing coating all over and leaving the crank pitted and a oil filler screen full of the coating
Clean and polish up those aluminum crankshaft journals and fabricate some PTFE bearings. Teflon has a coefficient of friction (COF) of 0.05-0.10, which is the third-lowest COF of any solid material. The material properties of PTFE aren't the toughest but the material properties of conventional everyday engine bearings aren't very tough either. Garage54 is definitely the most qualified to find out if Teflon bearings will make this aluminum crankshaft a functional and reliable option
The shell bearings on a crankshaft never touch the crank in use. The relative friction coefficient between materials is irrelevant. They run with a film of oil in between, the only time they ever touch is on startup or in extreme circumstances where the oil film breaks down.
@otm646 I understand how the oil pressure system works in keeping the bearings floating on the oil.

A Lada is a FIAT 124 but with its steel body three times the thickness. So you have compensated for the weight increase by machining an aluminum crankshaft. _This makes sense to me!_
back in the 70's etc when they were making deep diving crab suits (bearing joint angle things) out of aluminum they were using mass compression forges and heat curing to make incredibly tough alloys. I suspect such would result in better wear surfaces on the crank but the application structure and method for the journals and slips on the block would be where you'd have to mill to fit the crank instead of the other way.
That was cool. I enjoy watching experiments and their results. One day when I visit your country I'll have to make a quick stop by your shop! Great content
Hey guys, great fun once more as always, thanks. Have you tried trimming down a regular steel crankshaft to see how light it can allow the Lada/Fiat engine to operate. That would be interesting.
your crank journals will have an expansion of around 0.3mm at working temperature. your stroke will expand around 0.4mm . Thats one of the best videos you made so far.if you redo your clearances and heat your engine before operation this could work
Titanium will not work because it does not tolerate friction well and will start to peel quickly.

@@justinmiller1191 its not about the weight or strength . Its all about how well it handles friction and expanding as little as possible with heat. This is why cast iron is still my material of choice when it comes to engines.
@@hermanbotha1449 It works for rods why would you think it can't handle being made into a crank? It would be difficult no doubt. Machining it is a pain for sure. Thermal expansion on the aluminum likely was was messed up the aluminum but aluminum doesn't have a fatigue limit like steel and titanium so would eventually fail.
@@victorthecarguy3126The rods have an interface layer or bearing insert at the friction point to keep them from spalling out. Harder to do on a crankshaft. Not impossible, but FAR more difficult.
Here's a thought for you to ruminate on... Four part races with cylindrical roller bearings for the crank and rod bearing journals. At least you won't have to put up with debris in your oil pan. Think of the frictional coefficients (or lack thereof), involved if you need a reason to try.
I had a similar idea. Since they are custom making a crank , might as well work in a roller setup. All things considered, I would hate to see how much it will cost to have it made by engineering. . . easily 10 times the price of 20 ladas. Its still nice that someone tried it so all of us can stop wondering.....poor lada....
My brother and I put a lightened flywheel onto his Mazda RX-7 and because of the lack of inertia, it had to be revved up all the time. That, coupled with the removal of his catastrophic converter, gave it a very distinctive exhaust note with extremely fast Rev acceleration. It is a good thing that the light and flywheel came with a heavy duty clutch to handle all of the slippage that it would be subjected to upon take off! PS, I enjoy your presentations!
Revisit the Crossplane crank idea, but from one solid piece of steel like you did with the alloy crank, and then get it balanced so it doesn't shake it's self to pieces..
@@martin-vv9lf providing the counter weights are sufficiently heavy at either end of the crank, they should be able to get a good degree of ballence. If you look at a V8 crank you'll notice the end counter weights a pretty beefy, just need to scale one down to a 4 cylinder size. I'd love to have a go at it myself but I don't have a lathe big enough...yet..
Wow I am amazed that worked at all with the weight of the counter weights being off, the expansion of the aluminum and the potential flex and deformation of the aluminum.
@@franzbeckenbauer7490 it pops up on the screen at around the 3:30 mark. Usually this happens when somebody is editing the video in Adobe Premiere, tries to apply the image stabilizer, but forgets to actually execute the stabilization process.
That was a worthy experiment. I was hoping the ceramic would protect the aluminium from chewing out and i agree that there should have been a lot more ceramic. I would love it if you did a part 2 of this one with some modifications from what you have learned already. Thanks guys!
The engine ran so quietly because the soft aluminum absorbed the impacts of the power strokes, instead of resounding from being hit by the connecting rods when the cylinders fired. My theory 🙂
It really feels like you guys are on to something here. If I were to try making the shaf again, I would try machining down the bearing surface and using high temperature solder, attach high carbon steel surface in 2 half-moon pieces to the shafts bearing surface. A good idea would be to probably use threaded locking pins to lock the carbon steel in place and just weld shut the ends. I haven't felt this much excitement about a project in a while. The engine was super quiet, especially for an old lada.
For it to work best the journal contact points of the crankshaft should be made of steel while the rest of the weights and whatnot be aluminum, it would all have to come into place with wedge joints and then be welded It would be a fair bit of work, but the results would probably be rewarding
This is the answer Oil not working on aluminum surface If you look closely, all the contact surfaces that operate on the aluminum blocks are iron Under normal working conditions, it doesn't generate a lot of heat You don't have to worry too much about the expansion coefficient
@@chibalkin actually it's from the editing software (the "click analyze..." bar usually pops up when you apply the image stabilizer to a video file, but forget to actually run the stabilizer).
that was an amazing video, very well done, considering you did all that work and still have the crankshaft, i wonder what would happen if you made the bearing clearance much bigger and used a MUCH MUCH thicker oil would it last any longer? , you guys are amazing please keep up the great work
This is one of your best ones.I think the best idea. Maybe if you could spray that nickel and crome powder spray and then heat it up. You know how they do it. How are they doing that with gears and other steel gears. Maybe you could do that on the journals of all the crank shaft and cam shafts and some mathematics. I know you've probably thought about that already.That's a little more work, though, but look like.Look what you're doing.You're developing something I like it.😊
Great video, this was a great experiment, I think with a few tweaks you may have something, ie .003 running clearance, a fresh grind and some other high tech coating or maybe a better aluminum alloy.
Yeah the aluminium expanded for sure and most likely caused that. A bit similar thing happened on M539 Restorations channel too. I can't exactly remember how it was but I think Sreten got aluminium sleeves in a cast iron block and that caused the pistons to first eat up the aluminium sleeves and then when the aluminium sleeves cooled, the pistons started to cause piston slap and the pistons and the sleeves were destroyed. Here the aluminium crankshaft expanded so much that the clearances went away, oil film went away and then the two metals started to eat and melt each other out, even when there was ceramic coating on the crank. So I think if you try to install an aluminium crank to your car, you need a ton of clearances and such bearing and connecting rod materials which can take that beating of loose clearances before the crankshaft expands and the clearances become much smaller.
He's right about that cranking yes I'd be worried about the drone too cuz there's a lot of pressure set alarm for little motor I hooked a lot of motor survives anyway you guys are awesome man America loves you keep up the good work❤❤❤❤
54 i love what you guys do i think fhe issue is aluminum exspands several times more than steel and if the tolerance is thin youll just seeze up once she heats up.
well it didnt last, but maybe this is just the experimental start. BECAUSE IT DID WORK, and was exciting to see. maybe like other aluminum parts there just need to be steel inserts at the journals for bearings to ride on. i love that, "you cant do that", does not reside in this shop. GREAT JOB😊
That was awesome! I love to seeing the aluminum crankshaft in there. You all took th counterweights off of another crankshaft, I would love to see clean that one up on lathe, and see how long it would run for.

How about using cast iron bearings and using something like T6 aluminum for crank? Also more tolerance for a bit thinker oil. That might work? Fun project guys!😃👍👍
Nice, wonder if very hard steel bearings may have done the trick here, A2 Tool Steel for instance would keep the softer material in check... Changing just the connecting rods with lightweight rods on a stock engine makes a huge difference in performance.

You guys are the best at fabricating engine parts or any kind of part for the experiments you all put together kudos to you all. the maching work is excellent .
A titanium crank might be nice.
Titanium will not work because it does not tolerate friction well and will start to peel quickly. It is true that it is lighter and harder than steel, but because of this it is mostly used only for connecting rods, or for components that have friction-resistant materials in between (bearings). It is true that titanium connecting rods have a bearing in between, but they are on the side where the bearing is fixed and does not wear.
@@bernymonty22Also extremely cost prohibitive and difficult to machine.
@@justinmiller1191 its not about the weight or strength . Its all about how well it handles friction and expanding as little as possible with heat. This is why cast iron is still my material of choice when it comes to engines.
@@hermanbotha1449 It works for rods why would you think it can't handle being made into a crank? It would be difficult no doubt. Machining it is a pain for sure. Thermal expansion on the aluminum likely was was messed up the aluminum but aluminum doesn't have a fatigue limit like steel and titanium so would eventually fail.
@@victorthecarguy3126The rods have an interface layer or bearing insert at the friction point to keep them from spalling out.
Harder to do on a crankshaft. Not impossible, but FAR more difficult.
you guys have a lot of talent running a mill and lathe to make a crank; what great work and know how.
Here's a thought for you to ruminate on... Four part races with cylindrical roller bearings for the crank and rod bearing journals. At least you won't have to put up with debris in your oil pan. Think of the frictional coefficients (or lack thereof), involved if you need a reason to try.
I had a similar idea. Since they are custom making a crank , might as well work in a roller setup.
All things considered, I would hate to see how much it will cost to have it made by engineering. . . easily 10 times the price of 20 ladas. Its still nice that someone tried it so all of us can stop wondering.....poor lada....
@@hermanbotha1449 Well, I hoping they at least try...
My brother and I put a lightened flywheel onto his Mazda RX-7 and because of the lack of inertia, it had to be revved up all the time. That, coupled with the removal of his catastrophic converter, gave it a very distinctive exhaust note with extremely fast Rev acceleration. It is a good thing that the light and flywheel came with a heavy duty clutch to handle all of the slippage that it would be subjected to upon take off! PS, I enjoy your presentations!
Revisit the Crossplane crank idea, but from one solid piece of steel like you did with the alloy crank, and then get it balanced so it doesn't shake it's self to pieces..
that would be sweet. I'm not sure that balancing would save it though but certainly no harm to it.
@@martin-vv9lf providing the counter weights are sufficiently heavy at either end of the crank, they should be able to get a good degree of ballence. If you look at a V8 crank you'll notice the end counter weights a pretty beefy, just need to scale one down to a 4 cylinder size. I'd love to have a go at it myself but I don't have a lathe big enough...yet..
Wow I am amazed that worked at all with the weight of the counter weights being off, the expansion of the aluminum and the potential flex and deformation of the aluminum.
It will be cool to use aluminum connecting rod and crank shaft with a brass main bearing
You guys are awesome. It's pretty fun for me to see what we can do as humans. Well done!
Don"t forget to click to analyze.
Click analyze? What do you mean?
@@qpSubZeroqp Yes
Huh, I dont understand what you mean‘t by „to analyze“?
@@franzbeckenbauer7490 My guy. have watched this video or what? life would be easier if IQ score was displayed publicly.
@@franzbeckenbauer7490 it pops up on the screen at around the 3:30 mark. Usually this happens when somebody is editing the video in Adobe Premiere, tries to apply the image stabilizer, but forgets to actually execute the stabilization process.
You guys get more technically advanced with every vid. Bravissimo!! 👍
Ahhhh, it's almost nostalgic to hear the "translation by."
That was a worthy experiment.
I was hoping the ceramic would protect the aluminium from chewing out and i agree that there should have been a lot more ceramic.
I would love it if you did a part 2 of this one with some modifications from what you have learned already.
Thanks guys!
The engine ran so quietly because the soft aluminum absorbed the impacts of the power strokes, instead of resounding from being hit by the connecting rods when the cylinders fired. My theory 🙂
sounds good to me!
Yes! I've been waiting for this video since you guys did the aluminum valves. This video made my day thank you
0:49 Ah the fun of manual Lathes and Mills!
It really feels like you guys are on to something here. If I were to try making the shaf again, I would try machining down the bearing surface and using high temperature solder, attach high carbon steel surface in 2 half-moon pieces to the shafts bearing surface. A good idea would be to probably use threaded locking pins to lock the carbon steel in place and just weld shut the ends.
I haven't felt this much excitement about a project in a while. The engine was super quiet, especially for an old lada.
It will never last. Alumium will give way, it has no tensil strengh. It will rev up quickly tough with that light flywheel.
I like this channel. They test all the things i wonder about. I especially like the ball bearing crank video.
For it to work best the journal contact points of the crankshaft should be made of steel while the rest of the weights and whatnot be aluminum, it would all have to come into place with wedge joints and then be welded
It would be a fair bit of work, but the results would probably be rewarding
This is the answer
Oil not working on aluminum surface
If you look closely, all the contact surfaces that operate on the aluminum blocks are iron
Under normal working conditions, it doesn't generate a lot of heat
You don't have to worry too much about the expansion coefficient
Damn, you guys always go all out on these. That was some hardcore machining just for an experiment!
Click analyze to begin?
Adobe premiere lol
Pause the video
Warp Stabilizer
Please try to make engine with carbon fiber parts (where possible)!
fiber block with cast iron tubes?
@@juhajuntunen7866 yeah, with Carbon pistons and connecting rods maybe.
I love how when something fails you take it apart and see what it is in the same video.
Hello there! Have a great Weekend!🙌🏼🙌🏼
Seen the title and said holy,,,,, these guys are nuts!! And I like it.
click analyze to begin
i was wondering what that is too
@@subg9165 I think it's from the camera they are using 🤔🤔🤔
@@chibalkin actually it's from the editing software (the "click analyze..." bar usually pops up when you apply the image stabilizer to a video file, but forget to actually run the stabilizer).
You should try Hard Anodising on the crank and open up the bearing clearances.
that was an amazing video, very well done, considering you did all that work and still have the crankshaft, i wonder what would happen if you made the bearing clearance much bigger and used a MUCH MUCH thicker oil would it last any longer? , you guys are amazing please keep up the great work
Props to the machinist. Nice work.
This is one of your best ones.I think the best idea. Maybe if you could spray that nickel and crome powder spray and then heat it up. You know how they do it. How are they doing that with gears and other steel gears. Maybe you could do that on the journals of all the crank shaft and cam shafts and some mathematics. I know you've probably thought about that already.That's a little more work, though, but look like.Look what you're doing.You're developing something I like it.😊
I say cut the crank so it has more clearance and retest. You guys did a great job cutting out a crank from a solid piece.
You got to love the engineers in these vids. I my slef anengineer do respect the effort and thoight you dudes put in ❤
Great video, this was a great experiment, I think with a few tweaks you may have something, ie .003 running clearance, a fresh grind and some other high tech coating or maybe a better aluminum alloy.
Got to live these guys, they come up with all sorts of crazy ideas. Also the fuel filter looked empty alot of the you were driving!!.
That's a lot of effort for a short video. Keep up the good work. It is entertaining for sure.
That is some nice machining :O never seen a crankshaft being made before.
Yeah the aluminium expanded for sure and most likely caused that. A bit similar thing happened on M539 Restorations channel too. I can't exactly remember how it was but I think Sreten got aluminium sleeves in a cast iron block and that caused the pistons to first eat up the aluminium sleeves and then when the aluminium sleeves cooled, the pistons started to cause piston slap and the pistons and the sleeves were destroyed.
Here the aluminium crankshaft expanded so much that the clearances went away, oil film went away and then the two metals started to eat and melt each other out, even when there was ceramic coating on the crank.
So I think if you try to install an aluminium crank to your car, you need a ton of clearances and such bearing and connecting rod materials which can take that beating of loose clearances before the crankshaft expands and the clearances become much smaller.
He's right about that cranking yes I'd be worried about the drone too cuz there's a lot of pressure set alarm for little motor I hooked a lot of motor survives anyway you guys are awesome man America loves you keep up the good work❤❤❤❤
I think it is time for you guys to build a completely custom engine with all the tricks and improvements you have learned over the years.
awesome, did you balance the crankshaft?
Я приветствую ваше желание экспериментировать и исследовать работу двигателя. Спасибо за это видео. Привет из Огайо, США.
You guys need to combine ALL you lightweight things together in one engine!
Then I seen the scale and holy,,,, these guys are nuts!!! .COOL!
PLEASE MAKE ANOTHER WITH EXTRA CLEARANCE that was pretty damn cool. worth trying to make it work. could be a slapper when cold and quiet when hot!!
All funny experiments aside you can see how skilled they are.
Every idea on this channel is amazing
I’ve been analyzing things . 😂 love the channel . adobe premiere strikes again
Whether it worked or not the crankshaft was a thing of beauty.
54 i love what you guys do i think fhe issue is aluminum exspands several times more than steel and if the tolerance is thin youll just seeze up once she heats up.
1:35 ... Loved the mahoning video!! .. Very nice setup!!!
My wife suggests you run an engine on peanut butter as fuel. I'm not sure how this would work but if anyone can do it, it's Garage54!
well it didnt last, but maybe this is just the experimental start. BECAUSE IT DID WORK, and was exciting to see. maybe like other aluminum parts there just need to be steel inserts at the journals for bearings to ride on. i love that, "you cant do that", does not reside in this shop. GREAT JOB😊
That was awesome! I love to seeing the aluminum crankshaft in there.
You all took th counterweights off of another crankshaft, I would love to see clean that one up on lathe, and see how long it would run for.
These guys are fun to watch.
Great job guys!
Amazing work for a high speed steel grooving tool and some emery cloth.
Lots of forbidden glitter in that oilpan. Cool experiment though. Very enjoyable to watch. 👍
That ceramic coating is super cool
Love these experiments! I wonder what other metals would do like brass, titanium etc. But that would get expensive.
Witam serdecznie. To wał korbowy bez obróbki cieplnej,bez napawania na czopy główne i korbowe metalow kolorowych i indukcji hartowania. Poza tym najlepszy test silnika lady....!!!!!!!
How about using cast iron bearings and using something like T6 aluminum for crank? Also more tolerance for a bit thinker oil. That might work?
Fun project guys!😃👍👍
CHEERS from AUSTRALIA
you guys are stepping it up a notch with this - awesome! 😃
You already did gold valves, now it’s time for the gold crankshaft too😏
Nice, wonder if very hard steel bearings may have done the trick here, A2 Tool Steel for instance would keep the softer material in check...
Changing just the connecting rods with lightweight rods on a stock engine makes a huge difference in performance.
