Love the video. All of them are good. When I was a kid, my dad and I took a 405ci engine out of an old beat up car, and sat it in an old boat. We hooked up the propeller shaft directly to the crank on the back of the engine. Whatever rpm the engine did, the prop did to. That old boat would do 75mph and scare the crap out of us. Built the whole thing for about 700 bucks.
@@ROTAXD Russia is second world ;) If I remember correctly, the whole "first world" and "second world" deal is (or was) a reflection of the geopolitical situation on our planet, where you have developed capitalist countries (USA, Europe and so forth), socialist nations (USSR, China and certain Eastern European countries), and "third world" countries which don't fit into either paradigm.
@Ponga Pandit it goes flywheel - clutch - bell housing - gearbox. He left the first three intact and connected the shaft to the first gear inside the cut off gearbox. The clutch is there and functional.
I wish I lived in a country where THE cheap beater car to go to was RWD, manual, and had excellent rust protection... Basically the opposite of the USA
sadly most Ladas ARENT that rust free underneath. we had them here in the UK for a while and they were the only thing (along with Skodas of the era) that rusted as fast, or faster than the 70s Fiats (which the lada is pretty much a reproduction of the Fiat 127 but with a locally sourced engine due to costs at the time)
Volvo 240, esp 1975 to 77 with the B20 pushrod engines. Volvo 140 was awesome too but those been too expensive the last 25 years. Volvo always were primitive like Lada but benefitted from their primitive nature, the bushings and other rubber parts were horrible though, wasnt rectified before 1978.
How about tossing out the entire prop shaft and attaching a hydraulic pump to the motor and a hydraulic motor to the rear differential so you get a Hydro static transmission. A hydraulic lever like the ones used to control a hydraulic cylinder would decide how much of the pressure from the pump goes to the motor and how much just gets returned to the reservoir. Further you would be able to use the car afterwards as a mobile hydraulic power plant to power log splitters, hydraulic scissors and more.
@@rjs198585 True Hydrostatic Transmission is the correct terminology. Hydraulic transmission can also be a Hydrokinetic transmission or a type of automatic transmission. I have corrected it now, thanks!
That's been done in the States for several years now and the big fertilizer company's use the big wheeled units forspraying fertilizer and pesticides on the fields. These implements are big and will surprise you how fast they canrun. Since they are powered by a hydraulic pump driving hydraulic motors they have a lot of power. The tires on therigs are at least 8 ft. tall and the wheel base takes up more than a lane on the highway. That means traffic on thehighway will see flashing lights and a big farm implement that is traveling almost 45 mph pull over so there isroom on the highway for traffic to pass. They have the clearance and the power to run through a ditch. How aboutthat for offroad equipment!
i was waiting for them to tell us that but they didn't instead they destroyed perfect gearbox, did some shitty welding and couldn't even finish their own experiment..
I basically did this with a 70 Mustang doing 70mph. The 4speed ran out of gear oil due to a rear seal leak. First gear is the fastest free spinning gear, which is why it welded itself to the output shaft in an instant, popping it out of 4th gear. Slowed down REAL FAST to about 35mph in no time as the 302 shot up to 7k rpm, and then the front u-joint broke on the parkway by the old J&L mills in Pittsburgh PA. Attempting to pole vault with the now dislodged drive shaft, it pulled the tailpipe clean over the rear end and wrapped it around the driveshaft. Best thing that happened was a traffic jam due to the Squirrel Hill tunnels at rush hour, so I was able to peel away the exhaust and change the u-joint (had a spare) on the side of the road with cars going slowly by. Started it up having to hold in the clutch to stop while in the slow moving traffic jam for about 1mile, before getting off at my exit. It was also quite loud with no muffler or tailpipe.
The reason your shaft broke was not because of the rubber being weak but because of the big unbalance in the axle making it swing around so much it snaps. It could work to either way make a completely straight axle that is well balanced or use extra support bearings to keep it steady and you could rock with it I’m sure. But it was fun to see some parts flying anyway ;)
The prop shaft didn't blow out because of the load, it broke because of the imbalance. That's why it's recommended to get the driveshaft rebalanced when the u-joints are replaced. Once they start spinning and bowing out, there's no yoke on the planet that can withstand that kind of force. Great video, but to the commenters saying to slip the clutch; it wouldn't have saved it. Shock load didn't kill it, the rpm did.
The lack of support made it blow, i knew it would before he tested it. I once lost a shaft support on a rwd volvo 240 going 90kmh, the banging and shaking was insane but nothing broke, new support rubber asnd bearing and the car was good as new. Imbalance will not harm unless you got one of those Alfa Romeo Alfetta with rear mounted gearbox/transaxle, those italian DOCH engines rev very high with the axle between engine and gearbox moving at crankshaft speed.
These guys are great eh. Building a lata into a sprint race car...if you have time Chech out on RU-vid sprint car racing they don't have transmissions, battery, or starter they push to start for racing really a wild ride. .
+Michael Skřepský That is a VAZ-2101, they stopped production in 1988, so no, it's not a few years old. The more modern 2100 series ended it's production in 2012, which is probably what you were thinking of.
its not the rubber couplings fault.. prop shafts have to be perfectly balanced, and making it longer and adding more stuff to it is gonna throw it off balance and destroy itself ...
8:34 you can clearly see how imbalanced the driveline is, also on a 3 joint drive line, the front u joint (or coupling) has to be completely in line with the trans other wise there will be a massive amount of inbalance. the middle one and the rear will be able to cancel each other out. plus the trans mount was deleted allowing the motor to move up and down which puts unnecessary stress on the coupling and makes the inbalance worse.
Uhhh...yes a really good welder can weld a drive shaft together. It still needs to be balanced though. Even a stock one comes with weights because it’s been balanced. Yes they need to be balanced. Yes he should have used a clutch. Yes it broke for several reasons. Still it was a good video: we learned what won’t work. 👍
I think it had to much joints and not enough bearings to support it. The drive shaft just rolls up on itself instead of transferring power. Anyway, 4th gear ussualy is direct drive.
The production quality and shop has improved in more recent videos but you'll have stuck to your roots. Thank you for not doing like a lot of others and drastically changing. Also want to thank the translator for his work. I wouldn't be able to properly enjoy these videos without you.
1. build a support for whats left of rear of transmission, as well as a support bearing behind the coupler (transmission side) 2. use the clutch to ease the engagement from stand still, dropping the rear when spinning will shock load the driveline and hurt it no matter what. 3. try heat treating the new fabricated prop shaft to make it less brittle
That's just silly. Same as having it in high gear. 1:1. Why not put another gearbox backwards behind the stock one. See if you get super hyper overdrive. Go plaid.
So basically what we want is a collab between garage 54 and gear down for what? Imagine a 1,000,000:1 ratio, no way itd ever actually work, but itd be fun to watch!
@@hamstirrer6882 I'm pretty sure it actually would work since the secondary box would be acting as an induction gear instead of a reduction gear, in the end all you need to make sure of is two things: 1: That there is a conversion box between the gearboxes for proper shaft rotation. 2: That the secondary box is in it's final gear to ensure proper operation of the primary gearbox and that when the primary box is in top gear to start going down in gears on the secondary box to increase overall speed.
GRIFAbyte101 true but that would take some serious engineering, both in design and manufacturing, to implement properly, which isnt the point of this channel. Good point though, i meant it hypothetically and basically as a joke
it wasn't welded straight enough it needs to be balanced to hold together right I saw a wobble in the shaft from the start then when the rpms came up it self destructed really
I think it is the imbalance of the drive shaft that makes it fall apart. Just a single millimeter off can make the whole car vibrate and you can see the imbalance when he was recording under the car. 8:29
These guys have more and better tools than a big sawmill in Russia. I'm not even kidding. I've seen these guys use a MIG-welder and a ratchet set. Never EVER have I seen either of those in a Russian sawmill. Just so you know, I work as a mechanic for a big sawmill machinery manufacturer, making a lot of maintenance calls around the world.
@@DILLIGAF2101there is a shifter to put it either in or out of gear so when there working on it or bringing it to the track before starting the rear is disengage but when racing the engage it then push start the car kinda like a clutch
I don’t think so. It would either destroy the clutch (almost at impact with the plates) or it would have sheared through the valvetrain and/or the drive shafts.
You guys are crazy as a box of squirrels!!!!....crazier than CANADIANS......and that's a good thing....I love it and I subscribed...you do stuff we ALL want to do....but we just DREAM most of it....you DO IT Cheers from Canada North
And if you push start that is exactly what you are supposed to do. (I mean you are not supposed to push start a modern car but for that old Lada it should be fine.)
Žanas Tumasonis 4th gear is a 1:1 gear ratio on most cars. The only exceptions would be a 3 or 4 speed where 3rd is 1:1. Or one of the newer 8-10 speed transmissions where either 5th, 6th or 7th is 1:1.
the rubber coupling didn't exploded until it started flexing due to lack of carrier bearing at the end of the extension where the back of the transmission housing would have been
That was so balanced did u see that weld 🤣 wide enough to handle the torque my axle shafts thinner..... I hate engineers.... Can I kick you in the nuts?
The gearbox is there to remove the excess energy so the shaft will not break. That is why the shaft is breaking and bending because there is no gearbox. When we start the car and change gears the purpose is just one simple purpose to protect the shaft from breaking because of excess energy and the gearbox is the only way to do it. He should have studied the purpose of the gear before trying a new theory.
@@mwbgaming28 correct however it let go at a low rpm, thus less effect of the unbalancing = massive load. try taking off in a high gear and see what happens to a shaft unmodified
Direct drive works great. Sprint cars been doing it for years. Push start that baby and you're off. For years high gear was one to one anyway. Now we have over drive. Great video as always
You don’t see a American or any other channel like this, Russians are unique and this stuff would be illegal other areas lol best mechanic channel ever even if they can’t speak English or etc they are still an awesome group of Russians!
If you left the clutch in place.... why didn't you use the clutch by slipping it to load the driveshaft up slowly? Would burn through the clutch quite quickly but would give you more than a few starts before it went. Same as starting in 4th, or whatever the 1:1 ratio of the transmission is. I've successfully started in over drive before by slipping the clutch a ton. Just for fun!
@Turbo vr that's super weird because my android phone costs more than any rubbish apple you can buy. You're obviously mentally handicapped which is obviously why you're so poor that you have to buy apple products
We all crazy, and you're crazy enough to do what we want to see. The cool part, I'm learning a lot Russian cars.and on your prop driven air car, the load bearing you built was done expertly! So, your not just crazy, your talented as well!
You can, but traction is pretty much non existent and in harder surface like tarmak disks will break after little while. Also i do happen to know this from first hand experience... just dont ask why :D
