There's no way that's ever gonna go back in an engine and it'll run properly. There's a good reason that engine parts are cast/machined in high-tech facilities to very tight tolerances, have heat treatment, are balanced and have ground bearing surfaces etc.

[@user-nn8pj6of6k]

В 90-х занимался мотокроссом. Была у нас одна беда, клинил сипоратор шатуна на колене от нагрузки и оборотов. Он был с алюминиевой обоймой. Разбирали кувалдой колено, меняли на такой же, только с бронзовой обоймой, прессовали обратно кувалдой, на токарном станке с микрометром и с помощью кувалды равняли. В прицыпе всё ходило, обороты двигателя около +/- 8000. Но приходилось систему зажигания, якорь, переделывать, делать через виброкомпенсатор с резиновой проставкой. Но подшипники не разваливались, я думаю из-за того, что они не плохо держат продольную нагрузку, плохо поперечную. Ну а видео, да, может это от парового движка)

[@GDOG520]

He just changed the molecular structure of that by heating it up that high its definitely gonna brake

[@youtubeaccount9058]

Why else would he torch it before continuing to mill it? Must have been to ruin the temper so he could mill it more easily. Perhaps they send it off for heat-treating and final milling after roughing it out in this workshop?

[@bortaloanzia8775]

[@andretorben9995]

Total BS. You can see at 20:58 the crank journal next to the welding is clearly not running true. This thing is going to vibrate itself to pieces within minutes. I hope this guy didnt charge anything for this crap.

[@boduke2299]

Using an angle grinder to polish the journals yeah that crankshaft will last probably less than 5 minutes before it spins a bearing or wipes it out.

[@jack1d1XB]

NO ONE should EVER except the Re-hashed outcome of this job, it'll bust and potentially cause a serious incident!!!!!!!🤬👎

[@AdrianShawDrummer]

Come on! It’s genius. This is primitive stuff admittedly but where it might be impossible or too expensive to source a replacement, this is brilliant stuff.

[@sullivanrachael]

@@AdrianShawDrummer- No. It’s an attempt to be a genius. The method used is actually pretty good in terms of the design. The implementation is not accurate enough. Far too little attention spent on run out, or the overall length. If done to the dimensions of a drawing - okay. The final crankshaft is not going to run true on its bearings, if it even runs at all. I still have doubts about the metallurgy - steel can be welded yes, but in doing so the localised heating and then cooling creates internal stress. Ideally a component welded this way needs heating and slowly cooling to relieve the heat stressing. Or cryotreatment with liquid nitrogen. Either way, no attempt to relieve welding stress has been done, the accuracy is suspect - job is therefore highly likely to break once again, if the crankshaft even fits the engine again.

[@AdamToney]

I believe it’s accept, not except.. but I’m no mathematician.

[@josecarlosdossantosalho4388]

😮😮​🎉🎉@@AdrianShawDrummer

[@garycananzey3251]

U r 100% right. The guy never put an indicator on the journals. He left a sharp corner where shaft joins crank. You can see the shaft running out .060” or so. Not in America!

[@kevinn7686]

Definitely polishing a turd... Wonder how long it lasted to create a ticking time bomb though.

[@JePeVePe]

hahaha he measured the shaft length a bit like 'aaah this is about right' 1:22 ... holding the broken pieces 'a bit into place'

[@adenlove9207]

Since there's no quality control in the W/Shop , it shows there are a lot of mistakes, crankshaft concentercity is unacceptable, and usually, crankshaft shaft is hardened and by using torch for heating to soften the material for easy machining then crankshaft must be hardened back .

[@lechatvenere]

Maybe they hardened it back after this machining, I hope 😅

I get why this was done, but there is ton of things to improve. A) welds, probably shield welding would be better, but there is need to focus on equal penetration, you recive things out of ballance with uneven welds even after machining, also i would assume deeper welds would help, as i would not want to stand beside it, in case it would crack again with flywheel on. B) journals can be done and polished, but measurments are key, and even approach on sandpaper to do it evenly, shoelace withwater sandpaper, or better drill hole with little smaller diameter in wooden block thickness of journal. cut in hadt and secure with hinge
