How Cracked & Leak Cylinder Head are Repair With Pinning Techniques || Rebuilding Cylinder Head
Вставка
- Опубліковано 16 жов 2021
- Cracks typically form when a cylinder head undergoes too much thermal stress. Loss of coolant, severe overheating as well as sudden changes in operating temperature from hot to cold can all create the kind of conditions that cause cracks to form.

People don't have a clue as to how much time and effort it takes to fix things. Today everything is made to throw away. These guys really earn their money. This is a really good look into how things get fixed. Thanks for sharing guys!!👍
Other than the lack of benches and working on the floor, this is EXACTLY how we did it here in Scotland 25 years ago, when I worked for a small engine repair business. Even the machine tools are the same.... The twin of the big drilling machine they are using to cut valve seats, lives in my workshop.
was it then when alot of factories moved to pakistan from the uk?
can you explain why he drills holes at 6:30?
@@space_cowboy007 he's using the drill to clear out the rust and muck from the small water passages.
I'm also don't understand why these people don't us benches but I wonder if that crack isn't coming back?
@@CactosS do search for metal stitching, works pretty well !!
my knee blew out watching all these videos of these guys crouching down......
These guys have a go. It's very primitive but at the end of the day it will work and i just can't understand why they haven't found benches yet? My back and legs were killing me just watching it.
After you are born, you do the Asian squat everyday for the rest of your life. No need for chairs , or high type toilets. In fact, they squat on a western toilet .
That would require resources and those can be best used elsewhere where people can afford to spend money on dead tree that would be better used selling as fire wood or to make and sell the table.
I'm not even joking.
Sad thing is in any other country that head would have been melted down for scrap and the whole truck would have been scrapped years ago.
They prefer to work that way, if they preferred benches they would have them. It's similar in lots of countries, to them standing all day is awful they find this way more comfortable it's like sitting and working. I was married to an Indonesian for years it's the same there, we had a house in Java I made a modern kitchen with benches and my ex wouldn't use the bench for cooking, she preferred to have everything spread out around her on the floor while she sat in the full squat position for hours preparing a meal, if i try squatting down like that for just 10 minutes straight my legs start to feel like they are going to fall off and when I try to get up my knees are seized and my legs are numb from lack of blood.
@Random contaminate free doesn't guarantee a good job. But grit and shite all over a cylinder head definitely guarantees a poor job.
My knees couldn't take that squatting down like that very long before i did something about it one way or another. I'd make a homemade bench from a tree if i had to.
What I like about these guys is that they
REPAIR things they don't just simply unbolt a
Broken part and bolt on a new one..
Their work environment may look primitive but am always astounded by the ingenuity of all their projects,well done guys👌👌

They do it exactly the same as it happened in my dads garage in the 70’s and 80’s, the only difference is they work on floor and in sand instead of on the workbench but the techniques is simply the same, i have been helping as kid with this kind of work
I like how they clean off the parts, then lay them back down on the dirt...I guess it helps in the break in process.....comforting knowing most major airlines send their fleets over there too for updating and rebuilding.
Get over it
But admit they are good for doing all that in the dirt in the first place

They do those same techniques at machine shops everywhere pinning cast iron heads is a very old technique they even use it on aluminum heads. I have put heads on cars that were pinned.
Hard work, yes. Nothing special about the method.

Thanks Mate for uploading this video. I learned something New today. Using (CALCIUM CARBIDE) to check for leaks. Brilliant Idea. I never would've thought of using this for Leak check. The only time I've use this product was exploring Caves. I used it as Fuel to charge my Old Timer Lantern for Light while exploring Cave System. Now I have One more Tool in the Box, I could Employ without using Air Compressor when one isn't around. Thanks again Mate for the upload. I do appreciate this very much. Well worth the watch.
So that's what those "rocks" were that they put in the head! Great idea. For those of you who don't know, Calcium Carbide reacts with water to form acetylene gas - the gas pressure forces the water out the cracks.
@@joeylawn36111 don't smoke near it hahahahhaha for real though
@@joeylawn36111 The pressurized acetylene also makes the cylinder head into a giant fuckin' pipe bomb. 😸 I laughed when I saw them doing this. Don't uncork that thing near the head surface grinder... Kaboom, and now everyone in the shop can no longer enter an MRI room. 🤣

I just went into cylinder head repair, and this just knocked all the B.S. out of it.
On a dirt floor, in the 3rd world.
Great job!!
I spent nearly 40 years as a cylinder head specialist I have rebuilt many thousands of heads and repaired thousands of cracked heads but this is very crude although it might work . I used tapered cast iron plugs not bolts. But what they really need is a bench.
Читаю комментарии и гляжу что все такие продвинутые. Ваша продвинутость заключается в замене старой детали на новую. А эти парни настоящие мастера !

I have pinned cylinder heads before. And have watched my father pin a Cat block that had frozen and cracked the side. It is a lost art. But still a useful tool that has been put on the back shelf here in the States,
Throws in the dirt and then wipes it with the rag to keep it clean,love it
Retired now,when I was working we fixed a lot of things,before anything new was purchased that part or whatever better be totally worn out,I've done heads and blocks it work's, I'm very impressed with their work

After watching this video I decided to do my diesel heads myself and save myself $1500. UsDollars. Nice. Thankx for the encouragement. God Bless you Always.

Indeed these guys are impressive (though why are they always squatting on the ground? Tables are pretty easy to make!) However there are numerous machine shops throughout the USA that can do things far more difficult than these guys can do.

I so much admire these Gentlemen. Although I have a more modern machine shop and tools, these men follow the same basic principles. And better. We can buy standard valve guide inserts and valve inserts. But due to delays, I, just like these men, make my own sleeves a seats myself. It ends up quicker and it continually hones your machinist sense of touch. By that, I mean that instinctive feeling of when something is ready to press. Like valve stem guides and valve seats. Even I do not have the experience to use just an inside or outside non-microscopic caliper to judge a size! That is hundreds of hours in the job that speaks!
В Пакистане можешь не работать - не работай, можешь сидеть - сиди, можешь спать - спи. Поэтому там традиционно всё делается на полу и сидя. Морозов там нет, поэтому гаражи из картонок, снега, ливней и грязи по пояс тоже. Че напрягаться то?
they are true mechanics, able to fix stuff instead of replacing it with new.
really? like you know this truck doesn't come back on the hook with a bigger problem!
Still positively amazed at the skills of these workers. Here in the United States we would throw it away, we are stupid here at times. Thanks for sharing the amazing work of these fine men. Best Wishes & Blessings. Keith Noneya
You do know there are places called "machine shops" that exist here in the USA. Look for some videos here on the tube and you'll see what they are capable of.
@@aaronmccutcheon Yep have visited more of those shops than I can count. It's the cracked part that amazes me. Here in the state we just throw the head away and get another one because in most cases in man hours it's cheaper to replace a cracked head than repair it. Except Aluminum, most of the time we can Heli-Arc them up and machine them down. Thanks for the tip anyways. Best Wishes & Blessings. Keith Noneya
I agree......benches should maybe be on the to do list. Does not seem to affect productivity at all though.
These folk give a new meaning to the word recycling....amazing!
As someone who runs a serdi machine and works in a machine shop every day this is amazing stuff!! From one end of the spectrum to the other I guess...
I respect their work in primitive shop,but my knees couldn't take one hour of that squatting!
If you had been doing it all your life it wouldn't be difficult
Have not yet discovered the use of workbenches… or protective gear… lol.
I would like to send them a work bench
They would probably take it home and use it to dine off of. They are comfortable working this way. My back hurts just watching them.
Its their way of working if not culture!
These cultures aren't, and I don't mean this in a bad way, like those of the modern world where we work at a table or even eat. They do everything on the floor, they spread a blanket or a sheet down and gather around with legs crossed while all the food is centered, in alot of cases even silverware is not used. There's a reason they write from right to left, unlike we in this comment section. I don't mean any of this in a bad way whatsoever, it's interesting how there's cultures out there different from ours and I'm fascinated by it.
Pinning cracks, also called lacing, is something we did in the machine shop I worked in over 50 years ago. We used purpose made tapered cast iron threaded pins and locktite. The pins were designed to snap off at a specific torque to ensure correct installation. For long cracks we would partially drill into the first pin, install a 2nd pin, and so on for the entire crack. Never had a come back or issue.
У кого наждак для удобства на полу стоит?

Was Ihr mit einfachsten Werkzeugen und Maschinen macht ist ein Traum, habe sehr grossen Respekt vor euch, weil Ihr seid noch wirkliche Mechaniker wo repariert und nicht nur Teile tauscht. Und finde es klasse das Ihr euer Wissen und Talent an die kommende Generation weitergeben tut. Das einzige was ich mich immer nur frage,weshalb arbeitet Ihr nicht auf einer Werkbank, sondern immer auf dem Boden.
Ich kann nur vermuten, ich glaube aber dass es zu teuer ist, den Werkstatt mit Werkbanken auszustatten.. man sieht ja dass der Boden nicht mal Beton ist.. kann aber auch die Kultur sein.. in der Arabischen/Westasiatischen Kultur macht man vieles auf dem Boden.. früher haben wir gegessen, gesessen, geschlafen,… nur auf dem Boden, in den Moscheen sitzt/betet man auch auf dem Boden.. sogar wenn man aufs Klo gehen möchte gibt’s da Toilettensitze nur für Senioren oder Behinderte.. sonst wie in Japan auf Bodenebene..

With that pinning technique, is the bolt material have the same heat coiffecient of expansion with the engine head block? Otherwise if subjective to engine working temperature, there might be window for new crack or opening on that particular area.
I've seen stitching like this before, usually though they use iron pins to do the stitching not steel bolts, this was a common practice on large engines back in the day, pins would be mashed into place with an air chisel, think its the only way on cast iron parts as welding won't work.
@@andicog I was going to say wouldn't it be better to tig weld instead of steel bolts? I guess they don't have access to expensive equipment but they wouldn't make sense some of their decking machines gotta be expensive along with the lathes.
@@forg0tin397 Even engineering companies fixing the blocks from diesel locomotives use cold stitching, don't think its a cost issue, more the difficulty in welding cast iron successfully.
