The piston is pressure die cast and has a completely different grain structure from the welding rod. This wont last for long in a heavy truck before the welded sections just peel off, but at least it will only kill the engine and not the driver.

If in the UK they did repairs like this, it would probably cost the same as a set of new pistons.. 😂

When you have no money, it is a terrible idea to install such a pos in your engine. It will explode, melt and/or seize in a few miles and you are looking at two thousand dollars in repair costs because you wanted to save eighty bucks for a new piston.

Wow!... Good Job!...

I'm pretty sure the piston will self balance after being installed.

I would think the weld would heat up at a different rate and remove itself from the part again. I have seen cylinder heads successfully welded up in ways I wouldn't think would work.

Not sure anyone would risk many thousand dollar worth of parts and repair down the line to save $150 on a piston like this. If include the cost of this hack job repair for this piston, you end up saving only $50. No way this particular piston will work. The top end of the piston been grind down smaller than the original diameter.

Great point! Its the same in Britain, the old skills have gone!

looks ok to the eye maybe ok for agricultural engines for a while, little use of pressision meauring insrtuments is a bit of a worry, reminds me of when i tried to fix a moped piston with "plastic metal" as a youngster, i can still smell it.

Just to get the views on their video they have repaired it, otherwise can’t be used in an engine. Even otherwise the new piston is not expensive here, so no reason to repair.

When there is no choice, this will work.

I was just mentioning this sort of thing to my wife. The LPW range were an interesting piston when the changed the design in later models. Expansion controlled, the crowns expanded to the correct diameter once at normal operational temperature. I rebuilt some and had to fit high rate oil pump, make sure the conrods had the oil jets. All fun and games.

does not worth the installation in any y engine, the steel fire irng groove is completely gone on two spots so the top fire ring will break in the few engine hours.

Bad idea. The low cost of a new piston doesn’t justify this repair. These welds will not last. This criticism is on the repair, not the workmanship.

Uhhhhhhh. NO. Too much material is being removed. Cylinder will not have sufficient compression. Cylinder WILL have added blowby. That is unless a sleeve will be used. But if you are doing to all the trouble of replacing the sleeve, replace the piston too. This is just dumb.

Yes, these guys place too much emphasis on cosmetic machining. Just machine what was built up with weld.

This piston looks like it is made out of aluminum alloy and the way this piston was repaired. (fill welded) I wouldn't trust it all. Most Aluminum is a very finicky metal to weld.

Relabeled video from Amazing Technology Process. BOO!! HISS!!! Fake repair!

This piston is stuffed. Forged from speciall alloy material, and they are cam gound, they are oval when cold. Plus the ring grooves are very tight in tolerance and they will not be. Waste of effort.

All through this video there is evidence that this is a cast piston. Apparently you are ignorant of the forging process. All you arm chair machinists profess your knowledge every day when you really know nothing.

Lol I seriously doubt this is a "real" repair, probably just made for the clicks.

one start and its all over red rover,it cant possibly work in a diesel.

1. Head piston diameter smaller than original. 2.segment rings larger than original. 3. Weight piston different tnan original (balance, group piston selection). 4. Aluminium utilised for repair not the original aluminium alloy. You want more? Craftmanship excellent. Utility none. Wasted time, aluminium, electrodes, electricity, turner wear etc. Stone better than this aluminium horror, as paper weight.

高温に晒されるピストンに、ロウ付けとか無謀すぎだろ😂 こんなのエンジン掛けたら溶けて終わりやで😂

Utter jUNK !

Pretty dubious, mechanically and economically. You've invested a day or two of labor into taking the engine apart. A new piston is maybe $60. This patched piston *might* last two months. Pretty dubious.

I call BS on this repair. The weld is just laying on the suface.

He turned a piece of scrap aluminum into an expensive paper weight, Why not buy a new one.. Hastings sells them cheap....

I think they are laughing at us for viewing. That piston can't possibly work.

I bet it lasts or they wouldn't be doing it. Poor mechanics these days are a slave to the parts manufactures in North America. Sadly they can't fathom such things because to North American "professionals" this is extremely unorthodox.

So we end up with an under sized piston with god knows how much the ring slots have been machined over width. This is just another in a very long line of KZread "Click bait" spoof repairs.

Sell a few coconuts buy a new one

Will not win a F1 race but perfect if you got no spares

Such a waste of time ; that piston won't survive in an engine under normal use . I guess if that's all you have then maybe roll the dice and watch it fail maybe trashing an engine block too
