@@UpVoltageOverclocking these ladas are so common in Russia, it's like if we did the same thing to say... A Chevy cavalier. To us it has no value, super common, and junk anyway.
@@UpVoltageOverclocking Its not like its some aluminum blocked Hemi, Side-Oiler 427 Ford. Those old Russian 4 pots are as common as a bottom barrel SBC
The imbalances of the crack shaft are compensated between both halves, so there is no vibration, but it increases the forces that the middle of the crank shaft has to support as each part of it is unbalanced. My guess is that if you go full power in gear at max rpm, it will fail, either instantly or after a bit of fatigue.
This has become my favorite automotive channel! Removing the counterweights on an inline 4 cylinder engine doesn't really change the balance though. The counterweights are really only there to relieve flexing stress on the crankshaft on inline 4s. This really needs to be tried on a V6 or V8 engine, which relies on its counterweights much more for engine smoothness. Great channel though, guys!
Was a perfect summary of Russia when he says looks ok to me while holding a throttle cable revving the engine full with no sump on. I’m sure it will get you home
Mate. This is no word of a lie, I had a rover 416, with a honda motor in it. I was working in a quarry, (unpaved gravel roads) I smashed a hole in my oil pan. And was freaking out. Not only did the car get me home. It ended up doing 23,000ks before it blew a head gasket! I honestly was like wow, that was impressive! I was sad too see it go!
@@glen7463 haha same. Lada cars used to be the laughing stock of my childhood. Everyone took the piss out of lada, same as skoda. But noone is laughing at skoda any more. And ladas are not looking so bad now either thanks to this channel.
You should watch the one they do with removing spokes from a 5 spoke rim. It gets down too...I wont ruin it , but its impressive how much shit they can take.
This is the real heart of a super mechanic, never want to spoil a good engine, this is how they work always, that is why most of the mechanic uses old vehicle you can see them on the streets,
You got really lucky on how balanced it is. It should have ripped itself out of its mounts. Back in the 80’s I bought my ex wife a Mercury Comet. It was like Ford’s Maverick. We got it used and I was in awesome shape. But one night when she got home from work she said it was running really rough. I told her I give it a tune up that weekend, but she said no, there’s something wrong with it. So we went outside and she star ted the engine while I looked under the hood to see what was wrong. The damn motor wanted to jump out of its mounts. I borrowed a timing light fr9m a friend and the timing was way off, like 105 degrees or something. I don’t know how much because the balancers aren’t marked that far. So the next night I borrowed a pulled from work and tried to pull the harmonic balancer, but the bolt wouldn’t budge. I borrows a breaker bar and a piece of pipe and finally got it loose, but the bolt was sheered off at an angle. So I drilled and tapped it, and used an easy out. I finally got that piece out and pulled the woodruff key so I could install the new balancer. But I couldn’t get the bolt in that crank. At that point I had a friend c9me over and we managed to get a look at the snout of the crank and there was a third piece of the bolt still lodged in it. We finally got that out and while we were underneath the car we discovered that it had been in a front end collision. The entire doghouse, subframe and all had been changed. But whoever did it did a damn good job because. It took something major to find where it had been damaged. Anyway, after replacing the balancer it ran great. I loved that car and was going to build it up, but my ex got the car in the divorce.
well guys you could've of tried running car on road for instance , but besides of that , this series proved of engine being very happy to lose some weight , i liked it , shame i can't understand russian , so i can wiew a original content , but BMI russian is realy a savior for us non speakers
if you watch the reving crank from the front the crank is going to look like someone trying to swing a hoola hoop around its waist , even when oiled normally its going to wear out the center bearings and snap eventually could pump oil intoo the oil pickup using a pump and a hose and just let the oil flail around when the engines running and clean the floor up afterward you can hack parts off the counterweights give whats left a knife edge so it has less resistance rotating through oilvapour in the pan fit forged aluminium rods , weigh out the small ends and pistons to match and get pretty close to balanced again (need a balancing machine to see if its good) , it will still wipe out the middle bearings though but will rev to the moon
Some time ago I've worked in a engine factory for a whole year and putting in crankshafts and the bearings was what I did all day long for 9-10h. I'm so used to look at these damn crankshafts all day that it was a really weird feeling to watch this video, I can't even describe it
i think what most of us want to see is an engine stretched to it' s limits. if it blows up well we still learned something. what is bad to watch is abusing an engine just for fun. waste not, want not. leaving the oil pan off was not good - we know that will tear up an engine in short order. so it blows up and we rally have not learned a thing. a waste of an engine. i have often wondered about the weights on a crankshaft. i just don't see how they can help. i would love to see an engine without the counterbalancing weights put to the test. love your channel. kudos.
I have already filed down piston skirting on either side of the wrist pin, until it was basically the wrist pin and the only 1 inch of the piston tops, let me tell you it had some major rev to it. But it did grenade later.
Story how did they built Chernobyl nuclear power plant: Q; Hey fellas we need to build new power plant! Vlad: Hold my vodka ang give my angle grinder :D
Reminds me of the old Prolong oil additive commercial where the pulled the pan off and ran the engine fully dry. Even go so far as to spray the crank with a water hose.
I think it will shake it self to death. Well I will be damed it still ran fairly smooth put a pan on it and drive it a round a while see if the mains can take it.
Yes, I thought is was bound to shake like mad as it is now nowhere even NEAR being balanced. Perhaps spending the money on getting the crank balanced at a shop is just a waste of money! ;) I also would love to see them put it all back together and drive it and see how it goes. I am thinking that once you put some load on it, it will then shake like mad. It runs smooth without the webbing with no load on it. Still, I was surprised by even that!
In the 90's I was into drag raving. I would cut the crank balancers to a knifes edge. That way they were more likely to glide through the oil instead of the blunt edge slamming into the oil
I always wanted to build a small 4-cylinder engine, remove the webbings off the crankshaft do any balancing on a lightened flywheel. Something like a Ford 2.3 l or GM 2.5 l
The weight of crankshaft is also for enertia so engine doesn't stall when load is applied ,I'm a mechanic myself and I really dislike this channel. we used to make things better than this when we were kids
The webbing is really not for balancing the motor. It's for balancing the crank. While it will work just fine. The bussing will wear out quite a bit faster
Hola estimado, mis profundos respetos por compartir sus conocimientos desarrollados en sus experimentos, créanme que son de gran ayuda. una consulta con respecto al funcionamiento del motor, han probado el vehículo en movimiento con esta modificación, hay una mejora en cuanto al numero de RPM o en la potencia, o solo hay efectos adversos al hacer esta modificación??
That poor Supra! Who knows what they have done to it if they are cutting webbing and running cars with no oil it's possible that Supra had something bad done to it!
you guys should build a DIY lumpy cam. run a bead of weld down each of the cam lobes, sand it real smooth, and keep them all as close lift as possible. could be done with vernier calipers. very curious to see how it'd effect this engine. you could also lighten the flywheel on a brake lathe :)
Episode theory: Hook a 12v power inverter to a car. Hook a 110v battery charger to the inverter. How long can you power a tv, a fan and a stereo without cranking the car up or until battery dies. I did this for a hurricane after it knocked our power out and some interesting things happened. These guys could really put an interesting twist on that I'm sure!
Where you will see an issue with the weights hack off is under load...my suspicions are that it will stall out trying to take off and climbing hills and inclines ..with a big heavy flywheel you will have something to help with inertia but i suspect you wouldnt go too far with an automatic...you should have test driven it a little with pan and oil ..another thing those weights do is throw oil ...
Thinking about cutting the webbing of my 350 slight degree just to give some splash of oil to get to the viltals and run but balance is the key so I'll give more thought to it
Those are called crankshaft weights,counter weights,without them ,as long as crankshaft is balanced ,engine will work ofc normally ,but it will lose some of it power.I am farmer,and at one of our tractors we did engine overhaul,engine from factory had crankshaft with weights on them,something similar like this one,but they could be removed ,had screws on them.Anyway after engine overhaul we just added crankshaft without those weights and engine lost some of its power,or at least on lower rpm untill he reach higher ones,i guess something like torque.But indeed it rev easier ,ofc it will when crankshaft is lighter,remove flying wheel and it will rev even better.
Good to see for once someone on the internet that uses there brain and not ruining something that would actually be useable for something other than "science"
What's great about these guys is they go above and beyond with their wild experiments. These are not builds, but experiments doing things we wonder, but would never do to a good motor. Dotchvadania (spelling?) meaning See you later Crazy Russian dudes. This engine should be called Partouch(spelling) Russian for Fartknocker since that is what this motor sounds like. A Fartknocker!
Guys you should have popped back the oil pan and all accessories on and taken it for a spin with some load. An engine vibrates more on transient with loads, accelerating the car from a stopped position for example. That would really be interesting to see how it behaves under heavy accelerations without the balancing weights ! I don't think it would last long to be honest...
They would probably sell the cut-up engine in the Russian Newspaper Ads: "Engine like new - lots of work done". "Highly responsive". LOL! Garage 54 always finds a project. Now get the Lada to run on pure Vodka - if that has not been done before!
