Świetny pokaz naprawy głowicy. Szczegółowo, nie ukrywając szczegółów. Ogromnie przydatny. Przekazano wiedzę, której trudno znaleźć w książkach. Ten film to rodzynek !!! Nie spotkałem takich nigdy. Podziwiam, pozdrawiam i dziękuję.
man.., I love this kind of stuff. that was awesome.., instead of buying a new head, you totally fixed the old one like a Road Warrior.
All those amazing, high end, expensive, precision tools... 😍
Sadly soon all combustion cars and trucks including classics will be banned from public streets in entire EU and Scandinavia :-(
In Germany the Green Peoples Party gave order to shorten fuel supply from 2025
on by reducing all conventional fuel stations to only one state operated central gas station per city or county. Car washs will be forbidden too because they are climate killers, now they want to slow down all the gas station pumps from 20 litre per minute to 2 litre per minute...From 2027 on in the EU certain car spare parts will be banned too....as exhaust systems, turbo chargers and even some engine and gearbox oils...California and New York will do the same from 2027 on.... So no investments should be done in oil burning cars any longer....They even created a new kind of crime here, called emissions and smoke crime.!!! (BABVVEN & TEBBVEN & BEFVO laws)!!!!!!
What is the valve seat material?
Cast iron
А стружка как у стали
Greetings from Argentina. U are amazing.
The best!!!!

Love your work
Учитесь у пакистанцев, им не нужен вагон инструмента, чтобы отремонтировать головку блока цилиндров.
great technique, and great tools công😄👍
Nice video, thank you. Your tools make me envious. I have a flow bench and you were in a great place to improve the flow simply by boring the valve insert seat to .9 diamanté's of the valve and then do a back cut on the valve seat. That would give you a bigger flow gain than porting the head.
cheers and nice tools.
Do you mean a thinner valve seat? (Smaller inside diameter?) and then adding chamfer on backside of seat towards valve guide?
@@muushkin Most people when porting a 4 stroke head focus on the port and narrowing the boss around the guide. but the biggest flow improvement comes from the valve seat area. Measure the valve OD diameter then bore in past the insert about 5mm exactly 0.9 of that valve diameter OD and blend into the port with grinder. Then cut the 45 degree seats and use the 30 deg top cut to position the head valve seat where you want on the valve. Then a very important step is to back cut or grind the inlet valve to 30 deg from the 45 deg seat edge towards the stem so that the valve ends up with 3 angles and the inlet seat seat ends up with 3 angles. Clear as mud I bet😁. Flows like a stream train 👍
@@markjohnson6130 I go .9 on the intake seat and .85 on the exhaust.
@@mikerieck306 Small world Mike lol. I linked into your dyno Vid, impressive stuff, it sounds really quick in the higher RPM, kept the dyno operator reflexes on the ball.
Наверное дешевле головку купить....чем за такую работу мастеру платить....
What grade steel did you use for the new seat? Great video.
42crmo4+qt
Attention to detail , same principal as a custom Chevy cylinder head . Nice job .
Интересно, металл имеет нужную термообработку. А то кажется сделано из сырого куска металла.
А трещину между седел не заварил...
Great demo , cool Tools and a lotta Work ! thanks I felt like I just did a day in the shop:)
Метал седла слабый. Слишком мягкий. Долго работать не будет.
Лаикккк!!!
A great demonstration clip with profound wisdom that really pays off. Thanks Paul !
I have done hundreds n hundreds of these trx heads guides also shift get loose
A easier way of removing seat is to shrink it with weld basically falls out i use to use kerzan valve inserts kz3819 they are extra thinker than the average seat insert the valve height out the back is 37-37.5mm from spring bass to valve tip i also make oversized guides
👍
Хорошо бы перед таким серьезным ремонтом заменить направляющую втулку клапана, что бы базирование пилоты было более точным, и полностью восстановить ресурс сопряженных пар трения.
actually I want to do like you. but because in my country there is no tool like the one you are using. even if there is a very expensive price for me the poor. can i borrow your tool? hmm.. sorry just kidding. good job and good luck
тут инструмента на милион новых головок 😂
I enjoyed the video and the presentation it was excellent. Not sure how accurate the machine can hold a concentric tolerance. The most important critical thing is valve seat to valve guide concentricity. What tolerance are you able to get the seat and guide to? Otherwise known as valve seat run out. Do you measure it after cutting the valve seat? There is a measuring tool that fits into the valve guide and places a finger clock DTI on valve seat and you rotate it to measure if the valve guide is concentric to the valve seat.
Valve seat concentricity can never be better than the concentricity between the valve guide and the cutter arbour. If the guide hole is worn oval, then it is better to replace the guide, and start afresh. Expensive head machines use compressed air to create a self centering effect between the tool arbour and the valve guide. When cutting starts, the tool and the work "define their own centres", and the concentricity is produced automatically. (Allowing for clearances)
It isn't overwhelmingly critical, unless the parts are grossly miss-aligned, because the two working faces are conical, and tend to self align, at the expense of a little extra friction and possible valve stem and guide wear. If the oil seal on the guide is good, then you wouldn't even notice, especially on a generator.
Nice work,big like from you'r follower....Respect!Arad-Romania if you know where is it..:-)))
OLÁ. 26/12/23. Completando... a ferramenta utilizada é ÓTIMA mas faltou o acabamento final que indica a área de vedação que se tiver invertida poderá em muitos motores provocar a "flutuação de válvulas" que as vezes é confundida por "corte devido a rotação excessiva. ABRAÇOS...Roberto Udo Krapf
beautiful work hug from portugal
いやいやいや、完成してないって。すり合わせやってないやん！
No, no, no, no, no, it's not finished. The taco bar isn't ready.
Tutorial yg sempurna hasil yg maksimal .ful support from indonesia 👍👍
Could you please indicate at wich temperature you need to heat the head and what is the (very impressive) refrigerant spray ?
The precision tool for measuring valve seat counter bore diameters is excellent. Never realized such a tool existed and figured you'd just use verniers.
why was the old seat look magnetize when machining it
Can always make dry ice. Baking soda+ acid and i forget the rest of the procedure. For dipping the parts that is. Not sure if you're aware but a lot of the comments are from bot/ fake accounts. They're typically the colored letters and don't have a picture 🙏
Great videos 👍
I watch what you were doing. WTF
The whole you bored was almost .200
larger than the new bushing. You don't have to shrink the bushing. You have to make a new bushing. As a retired machinist. The bushing and the bored hole should be identical in size. Heat the aluminum head and freeze the bushing.
Press it in and you're done.
This is not rocket science.
👎👎👎👎👎👎👎👎
great pro work mister your video is very educational, i did replace valve seats on a honda xr 250 work done by a local workshop is a few weeks the seats were deformaτed by the valve stroke on them,,,, where are you located?
many thanks in advance peter
Nice presentation thanks 🙏 👍
great look expensive
Como siempre da gusto verte trabajar, buen video.
O cara é muito profissional.
Outstanding work man well done
Richtig geil 👍👍👍
Amazing machining skills, but I'd like to know the cost difference of you repairing the cylinder head versus just buying a new cylinder head? :-)
Just love your videos!
Clear to see the damage due to heat. Any background information on the rest of the engine?
I guess honda did not intend something like that to happen. Is it sure it won't happen again after the repair? What was done wrong for that to happen?
Thanks.
Excessive engine overheating in the field - logging.
@@PaulXchannel Makes sense, thank you 🤓
I have never seen such a good work before
Do these bikes still not use hardened seats? I know cars do because of the unleaded gas and other modern fuel tech.
watched the video thoroughly and enjoy it thought you deserved a comment, just out of curiosity how do you perform leak test ?
Fantastic vídeo!
A big hug from Brasil.
Your lights in the workshop are flickering like crazy. It is not really visible with bare eyes but it can cause premature fatigue and headache.
An old timer told me you could use the material of an old camshaft to make a valve seat.
Инструмент и исполнение на высшем уровне ! Похожее имею. Одинаковый у нас с Вами только маркер !
Informative video. Could have chosen a better time to show off your film school artsy fartsy side though. I found myself fast forwarding over a lot of it.
Profissional de mão cheia. Parabéns muito bom seu conteúdo. 👏👏👏👏
If I wann a super powerfull cylinder head how I send u from indo ?
I use PC air duster to freeze parts. Costs less than half of those "freeze sprays" and does the same thing. Just hold the can upside down so the liquid comes out.
Kaleng pendingin itu kok namanya tahlil,...
Very ASMR and funny edit. You might want to tag that in the vid to get more views. 👌
How much this item cost brother?
Is the tool in 3:56 minutes called valve checking pressure? Anyone knows?
What kind of press fit do you use on your seats in a 4 valve head (TRX450)?
great tools..amazing
Что скажешь, приятно смотреть,и есть к чему стремиться и учиться.
This is what i had in mind when restoring my 2008 yz250f cylinder head when an engineer told me it cannot be done ever
Anything can be done with the right tools.

Ola colega .poderia imformar qual.o tipo de aço q esta usando para fabricar as cedes .?obrigado
That was some outstanding filming. Thanks
Are you selling these valve seat machine?Please share ball locking system.Thanks.
Bạn là một người thợ giỏi dó chúa che chở cho bạn
Good replacement and precision tools and carefull measurement but i see some sharp edges above the seats carbon deposit might build up there
Tanto perdi nn trovi il diametro giusto e una ruota che gira anche da te ti sento insofferente perché ai più nemici tutte le mattine che amici!!!!
Good morning sir i want to ask sir what cain of matirials do you use to mike valve seat.take you
42crmo4+qt
Все супер, но посмотрите на Ютубе ролики как индийцы в ручную делают тоже самое!
using localised heat- aka torches is really the wrong way to haet any aluminum cyl. head.
จ่ะชื่อบาวาล์วแบบนี้ได้ที่ไหนและใบวาล์ว
Garanto que fica mais barato comprar um novo
Sale mas barato una nueva por Amazon....
😳master, teach me thine way😳
I wish I had a small shop & all the toys to do rebuilds. Where are you located, do you fix other dirt bikers nightmares?
Well thank you.

молодец)))странно что не кто из русских еще не спросил почему клапана не притер)))
I wasn't confused until he mentioned an overlap of 0.1 mm. I watched that far in the video and finally noticed he was using metric.
Good and clean job.Try to pour some alcohol when you cutting the seat pocket at the head.you will have better wall surfaces.
jebus. The time and cost.
Isn’t the intake valve bouncing (at the end) a sign of it not seating perfect? Nice job by the way and love the video.
the pressure test showed that it was okay
@@PaulXchannel good to know it doesn’t necessarily mean it’s not right. Thanks for the reply. I just discovered your channel and love it, binge watching right now!
Excelente, ^^
Good job ,cool diy mashine :)
Buena demostracion de medios mecanicos pero...... y el esmerilado de valvulas ? os habeis dejado lo mas importante. Quiza saldria mas barato una culata nueva
Super high precision instruments.
Please restore the Satria Fu 150 motorcycle head block. Greetings from Indonesia
Отличный ремонт!
Time 16:09
Please let me know the name of the tool and the company
Also the kit price
I am from India
Thank you
Made in my workshop.
See my other videos.
Al lavoro allora sei nervoso sbattilo dentro con il martello di plastica
แล้วมึงไม่เทสก่อนเหรอ
Don't the valve seat inserts have to be hardened? As far as I know, this is the case with engines that run on unleaded petrol. Still great repair.
The material for the valve seat is hardened in advance.
@@PaulXchannel OK ;-)
Como se llama la herramienta para hacer los angulos
Excellent work! What temperature do you heat the cylinder head to when fitting the seat insert?
Thank you.
a drop of water on a hot cylinder head must evaporate immediately
@@PaulXchannel Thank you
Talent work. Spary cooling liquid before insert seat is a very good idea. Can we use this for " brake cleaner " contact cleaner " or petrol?? What is ur idea??
Really admire your professionalism in the equipment and tools you are doing the job.
Wish I had those equipment,
Just buy one they're a dime a dozen
what country are you in and do you accept orders for these works?

Buy new block machine bro
What is the degree of initial abrasion of the sitting valve cutting edge? Please brothers answer
3 angles of the cutting blade - 30° 45° 60°
