Priceless Engineering // A broken antique model Peter engine crankshaft repaired by engineering work

[@John-oe5nb]

So the original thickness of the crankshaft to the hollow center (which I thought was for lubrication) is around an inch or so. It broke. The weld to repair the shaft could not be more than a quarter of an inch thick. Hard to say as some of it was machined down. We all know that a quarter of an inch is much stronger than an inch. This crank should last around 2 or 3 revolutions which is what the guarentee was for I am sure. The accuracy of the machining is a close as the wire feeler they used to center the shaft. The tolerance is probably in the plus or minus one fourth of an inch or so. I am sure the shaft front and rear bearings lined up, well sorta. A little 1000 weight oil and a really strong starter motor and all is OK. Well for a minute. Ear plugs recommended for the engine knock, but they would fit in with the safety sandals.

[@osmandemir7272]

Selam. Hello. There was an oil channel in the broken part, you did not do this. The connecting rod will be left without oil and the bearing will deteriorate in a short time. Your other mistake was that you should have opened a V-shaped channel in the part you put in the middle of the broken part and filled it with welding before welding. The welding you made remained on the surface and when you corrected it with a lathe, you took most of it and a thin part remained. In the last process, you should have hardened it by heating, you did not do this either.

Great machinist, this repair will last as long as it takes to sell the engine. Look at the metal, This engine never had an oil change.when will they machine the two main bearings…they are not in line….could be machined but the vibrations will shake the engine to destroy its self.

[@rustie61]

Love the dial indicating calipers. Actually, a nice digital micrometer would have been preferred, but when using a file to flatten the soft bearing surface, a mic wouldn't really be necessary since it's not being surface hardened, that crank won't last long anyway....

[@jamest.5001]

I believe if that were dropped on the floor. It would fall apart into 3 pieces! The additional piece of steel wasn't weld prepared. The weld are not near full penetration. Seems the welds actually holding it together by are thin as a sheet of paper I would have cut deep into the area between the different metals and welded them together starting deep inside the crankshaft. Then move to the next side. As it is seems simply dropping it would break it! It would been better to put a 12mm both through the crank . And weld it in through the break, then drill out the bolt. Atleast the whole journal would be welded. I don't think this is real. Just a video to post. Looks like a staged "need for repair" cut a junk crank in half, then video a bad repair of it! Sorry, alot of these guys do amazing work, not like lazy Americans . However this I feel is not it! This is like mailing your roommate a letter, waste of a stamp!

[@samrodian919]

It won't even go in an engine I bet because on first start up the thing would explode like it did in the first place. What a waste of electricity to show us how backward they are in Pakistan I'm surprised they were using callipers, and not just using finger withs!

Cool to see the process but isn't the heat treatment all lost when he heats it to cherry red with a torch? I've never see anyone do this to machine steel. I also wonder if they'll re-balance it.

They heated it like that to make it lose it's temper and be machined easier. Once it's all together they'll have it balanced and heat treated again. People make a huge deal over nothing...

[@samrodian919]

I would have liked a radius either side of the journal, maybe there is more to go, can't think a big end journal could be sized with a vernier gauge. also more care needed with protecting the crank end surfaces, these run oil seals must be good surfaces. Would have thought having the conrod present necessary to make this repair proper.

All broken parts must have the same axis of rotation. It is next to impossible to be as accurate as required only by using eye inspection. Inaccuracies result in unusual stresses in the crackshaft while it is rotating inside an engine.
