I bet that head stays on the road 10 years before they need another head repair. Simply amazing what ingenuity and fortitude these humans possess.

NOPE! The valves leak as do the valve seals. Compression is also higher due to cutting the deck so much. I'm sure the fuel in that country is not that great. It'll work for a few months till the heat treatment kills the gaskets. You forget the metal that's used to repair is different...

The amount of wobble in that locating rod was crazy. Its meant to slide in the valve guide and hold that cutter so as to not let it walk while cutting the valve seat. The whole crack being repaired required it to create a solid area that use to be hollow to allow for coolant or oil passages. The rocker studs that were turned red hot are not just noodles. But I was entertained and that is all that matters.

Yes, this is a salvage process to try to save an expensive head that is no longer in production such as these D343 heads. I was a Cat factory Service Rep in the San Diego area years ago and fought with a local repair welding shop there who was spray welding heads and blocks and claimed to have a "like new" product when done! We never allowed the dealer to use those repaired heads on a warrantable failure as we had to stand on their quality. Oftentimes the welded product did appear to be as good as a new product but paint can hide a lot of variations!! Buyer beware!!

[@marktaylor171]

There are many reasons why I wouldn't allow any "repaired parts" come into my shop. It's not a matter of if, but when they fail, they will cause a lot more damage than the hole unit is worth brand new. However, it is understandable when you actually think about what you're seeing. All of these videos that show assentully scrap parts being "repaired" are done in locations where everybody is very poor. These parts belong to a very old piece of equipment and are no longer in production. The few used parts are still in existence are expensive because they are no longer in production, and the owners know they can get a high price because of that. They can not afford that and definitely can't afford to buy another machine.

And if they say they can they give you an outrageous quote for the price. All the time hoping you make the decision to buy new. I think the biggest reason I can relate to these videos is for the fact I am sort of like these men. I will do everything I possibly can before throwing something away. I've never had a problem taking anything apart and ordering new parts to fix it. Now if it's something I really didn't like in the first place of course I don't fix it I strip it for parts.

I saw my buddy’s grandfather fix a head bolt on his old tractor. My buddy and I were putting a new piston in the engine of his snowmobile when his grandfather took the tractor out of the shop to blow snow. 5 minutes later he came back into the shop. Said something was wrong, it was leaking anti-freeze. Tapped on the head bolts with a wrench and found a loose one. Pulled it up and it was broken off. Flashlights, drill, air, vacuum. He drilled into the remaining bolt, used easy outs to remove the rest of the bolt. It was a 3/4” bolt about 16” long that went from the head down past the cylinders and threaded into the block down near the oil pan. He drilled a 1/4” hole about 1 1/2” deep in each half of the broken bolt. 3/16” holes sideways through the bolt into that 1/4” hole. Welded 1/4” rod into the bolt using the 3/16” holes filling them with weld. Add the second piece and welded it all together. Took it over to his 10’ machinists lathe and turned it true. Reinstalled the bolt and went back out to blow snow. All happened in about 30 minutes. That man fixed stuff, not replaced parts.

That is all well and good, but if you can afford a new head for the machine, (and can still get one), that is nothing wrong with buying a new one, especially if you may depend on it a lot. The chances of this work breaking again in short time is too high of a risk if you need the machine with as little down time as possible, and too high of a risk for anybody who can afford a new one IMO. This--is all they can afford. Quite capable grinding surface machines I saw though. They could have finished the job if they had a good sized manual mill instead of that drill press. They must have sent the head out to get that machining finished, and the seats pressed in.

When the rest of the developed world will go into a depression I'm sure economies and small industries such as this will survive and be a valuable asset for their country.

Astounding application of theory and technique

[@doberman1984]

How to distinguish an amateur from a professional? A professional knows what he screwed up. Maybe a period workshop. He may not have a laser measurement, but he knows how to use the available tools correctly and do a great job! It's a pity that the video has no commentary. It's monotonous to watch, but it's a great job in an old-timey style. I admire!

30/12 22 They have a Plough Grinder - ideally need to aquire a Jig Borer or Jig Grinder, or Universal Milling M/C. Blocked cooling passages ensures continued repair work. Were those smaller blocks used to surround the furnace ready to offer an exchange system ? What other services do they offer ?

We have not seen these kinds of skills in America since 1903 when Charlie Taylor built the engine for the Wright Flyer with nothing but a drill press and a hacksaw.

[@Virgocygni56]

He also used a hammer right?

[@TheClampettmobile]

Fantastic how the arbor wobbles... precision work. when inches count; lets go decimeters.

[@Virgocygni56]

I think they use metric systems it it is more precise than accurate in the sense that it offers higher repeatability of the same error in the long run, unlike the british system that is more mistakenly accurate, but not precise.... Did you get it it?

[@billchildress9756]

After being used to how repairs go here in the USA then to watch how others do it is absolutely fascinating and satisfying and it all works out fine!!! Give these guys some better stuff to work with and they would be unbeatable! Most shops would just replace a severely overheated and cracked head. Just give it to them and done!! Bravo!!

[@junkmangeorge6363]

The sad bit is, when all is said and done, and the head is re-installed on an engine, likely, as not, the head will be cracked, where it wasn't repaired, within a week. I have never removed one of these heads that wasn't cracked.

[@RenaissancManEng]

I like the wobbly valve seat grinder! I doubt it would pass a compression test but it might run at about 80% power.

[@ChristLink-Channel]

... and likely keep running for at least 3 or 4 hours...

Did we not see water-ways in the grinding stage? If so, how were they preserved?

[@skyrizione8811]

I was thinking the same thing

[@paulbains9152]

Furnace welding cast iron . The white powder in the bowl is the flux . They filled in the water passages up to the Valve ? Theres a company in Seattle Washington , that specialize in this , with modern equipment . Ive done it on impossible to get antique heads with Ni - Rod . Cooling slowly after is very important , I bury them deep in floor dry crumbs . Takes 24 hrs to cool down , still hot in the morning , less likely to crack .

It depends on how long it lasts, doesn't it? If it cracked again on you in 5 hours of use, would you agree with your own statement? :)

[@johnphillips3512]

@@EarthSurferUSA just the fact they try and don’t have the throw away mentality, you think they will do all that labor just for a few miles. Cast iron can be repaired. Just amazing to me

[@ernestwilson5591]

Incredible what these guys can do. I've lost count how many cylinder heads I had to junk because a machine shop condemned it, or just couldn't fix it. If the shipping was reasonable, I would send these guys a lot of cracked heads for repair!

I've watched it before but I couldn't understand how this recovery of a Caterpillar engine made in the industry works again with the same perfection... But I found it interesting...!

[@Virgocygni56]

It will work to perfection as long as the compression ratio is reduced from a diesel cycle level to a otto Cycle... or maybe a tricycle...
