Really nice work Paul. Your editing and camera angles are also top notch in this video.
Machining + engines/auto/moto = doesn't get any better!
Thanks
1st time ever!!! A guy that properly uses a torque wrench. One non stop motion til you reach the correct value. Great work
That is complete bollocks. Period. Who told you that crap?
@@dirtygarageguy lol the only reason most people don’t do one full motion is because they working in tight spaces, you’ll still get an accurate reading using the right tools
I certainly agree this is good practice due to the fact the clicker wrenches do give false readings when bounced. The shock loading from bouncing causes the clicker tab to be more easily over come from users perspective letting out a audible click before reaching the desired torque value.
That being said though, as others have pointed out; if the wrench is in good working order and no design flaw is present preventing it, the click tab will reset into the pivot pin. So on the next pull the wrench it will have been reset and able to obtain the proper torque value.
Great work they use to make cam shaft bearings then someone decided to do away with them. Bad Idea. Good to see how you got round it.
You Sir, are a very patient man. Very nice work. Cheers from Akron, Ohio, USA
Thanks
another great video, good to see a repair on the head rather than it going to scrap.
Thanks for watching.
Do you have a website? I would like to have this done, my bike needs this done.
Sos el mejor. Saludos desde Argentina. Tkm
World class video.
Congrats.
Top repair!! thank you! Subscribed!!!!
Once again excellent job,👍👍
I admire these people! 👍👍👍
É muito satisfatório a manutenção com as ferramentas adequadas
Incredible work sir
Nice work!
Sad part of this is that the factory if to blame for the problem here. If they didn't use plastic oil pump gears the problem would've been so common. I am rebuilding my 350 for the 2nd time because the shop that did the first one used the plastic oil pump gear that was available.
Excellent work 👍
awesome job 👍🏻👍🏻
impressive! you are the number one! compliments!
Thanks
Thats a lot of machine work. I personally dont know anyone with the equipment or the intelligence to do that job. Good work
@@holmes1956O Thanks.
holmes1956O wow job
Fantastic work, great to watch.
Thanks
@@PaulXchannel No probs Paul, love engineering, and repair engineering.
Que buen trabajo capó!!
Beautiful man!!!!!👏👏👏😎
These are the definition of perfect
Thanks
From Indonesia you good job mr.Paul
Thank you
How do you think that loctite will hold up? Seen as its on the exhaust side?
good job bady
I have 6x Honda XR600r Heads that Need this Exact Procedure, All have Wrecked Cam Tunnel Bearings That are Non Replaceable, Very Common Problem for XR600s No OEM Replacement Heads are Made & Would be have been Prohibitively Expensive Anyway! Nearly all XR's Die Oil Related From Cam Tunnel Failure!! No one I Know of Can Repair them, How you have Done here on the KTM, I think the Labour Costs would be Crazy Anyhow!! -Cheers for the Lesson How it's Done!!👍😉🇦🇺
excellent repair skills.
Thanks
Very nice....
Nice work💯💯🔥
Good job👍👍👍👍
Bizare Oem head engineering , overly complicated design . Nice work on the repair.
Great job
Muy buen trabajo excelente
Eso si va bien... Únicamente admisión sufrió desgaste?
Mantap bro.
Amazing 👏👏
Amazing wokrshop brother🤟
Thanks

Top, Very good, master

boa tarde eu tenho uma sx-f 450 2008 e ultimamente sempre que paro no fim de uma trilha o motor desliga sabe me indicar de onde possa estar o problema ?
motor trabalha bem e levou filtro de ar novo e vela nova e continua igual sou dos açores e não temos oficinas nesta ilha para motos , se poder dar uma dica agradecia muito obrigado .
Um trabalho feito dessa forma é uma retifica de primeira
As always nice work! Why do you put those large screws in? I know that they are to keep the bearings from spinning and that they are on the non load bearing side but would it not be an idea to put a small hardened locating dowel in the head that does not break the surface of the bearing?
Thanks.
It is better when milling the surface.
Thanks for an excellent video. Is there a reason to use aluminium instead of a more common plain bearing material like bronze or is it what was found in the garage?
Thanks .
The camshaft normally rotates in the cylinder head which is made of aluminium.
Bronze has a different thermal expansion than aluminum.
Good job
Thanks
Excelente trabalho sou do Brasil parabéns
How much is that process compared to just buying a new head
It depends on the damage.
How much does this repair typically cost?
I unfortunately have the same issue with my Husky 350 head, however the plain bearings have worn significantly more into the head an cam bridge, I think the head may be beyond repair, however after watching this video it has made me think differently.
Love watching you videos and repairs in what can be done, but from a cost point of view is it viable to have this type of machine work done or is it better value for money to buy new parts?
Thanks for watching.
The repair should be cheaper but it depends on the quality of the repair.
AWESOME.
Perfect
Super pro 🆗👍
Grande😁👍
amazing (y)
If you want to fix the bolts with temperature you need to use other metal glue. Loctite have a stronger metal glue. It’s green and you need 250° C to remove it.
I just had the oil pump drive idler gear pringle. Head needs this very repair done. How can I get in touch?
Super
I have a head of a 2007 rmz250 is damaged from the camshaft, won't you help me repair it?
Hi ,what tolerance did you allow on diameters .05mm?? and what grade or alloy did you use .Thanks Mike and great job.
0.04mm
AlMgSi0.5
TOP !!! 😀
I need this done
Cool cool. Very awesome.
Thanks
@@PaulXchannel I looked how you at work.
Its such amazing.
You have a gold hands and platinum brains.
I wish you good luck.
Thanks

Hi Paul X excellents video what type of magnet brand you use to remove the collets on valve spring?
Thanks.
The tool is homemade.
Old screwdriver and untitled magnet.
@@PaulXchannel oh so you answer this guys question but not the other guys I see how you work
Superb work Paul, takes me back to when I was in Engineering ... now I "tinker" :) ... love the work but how does the effort stack up against of a new head / cams ?
Thanks
çokkkkk güzel harikasın
Hello, very impressive ! in your video, camshaft is 21,96. What size de you use for plain bearing ?
21.98mm
Looks like someone had their fingers in those bearings with some sandpaper before you got into there.
many people try to fix it at home
but material is already missing
What would the cost be to have this work done on my 350xcf head?
Whats it cost to get that done on a yfz450 head
And that kids is why you ride two strokes...
😂
ok moped
mips 2 strokes break down too.
🤦♂️🤣🤣🤦♂️
Quá đỉnh.
Cool
Does this work? No hardening needed? Cheers
Not
what’s the cost for that process?
What would you charge to do this for someone? If you would do it.
Спасибо за интересное видео👍🏼,от нас лайк и подписка❤️ Заглядывайте в гости.
How do you solve the material cut from finished bearing by the slit saw?
first saw and then milling
@@PaulXchannel the order of machining in this video suggest otherwise
@@therealspixycat ???
@@therealspixycat i think you missed the extras he made, in one section of the vidro there are 8 pieces, presumably 4 are the offcuts that are less than half due to the slitting saw cut. I missed it first time i watched, take a look at 6 56.
You can fix it Witt babet bearings , its better qualitie & dont forgett the oil pump
Replease itt. or try too make the pump more power ❗️
Ok
Is the high performance aluminum beryllium cooper?
AlMgSi0.5
@@PaulXchannelthank you... from Indonesia
@@PaulXchannel sorry what's your name sir almgsi0.5?
Do you take on public orders? I have a 2009 kx250 damaged head. Thanks.
I do not provide a public service.
sir you want to collab chanel
Hey can you do this for me on another bike? 2015 wr250r
Does Hight Performance Aluminum mean 7075 alloy?
AlMgSi0.5
👍👍👍
Can you tell my is this 7075 grade aluminium or something else. reguards Bostjan
AlMgSi0.5
not with check sounds? ohh
How much is a job like this?
Why not tig weld aluminum on it and then machine it instead of making suplements?
For thermal deformations.
Hello Ich have Husky FC 350 the Zylinder head ist so damaged can you this repair im from Germany ...
I am sorry.
I am busy.
Can you tell me the name of the tool used at 4:43 ?
Thanks
adjustment boring tool - made in the workshop
@@PaulXchannel Hello Paul . I'm glade to talk with you. Thanks for your quick answer. Do you have thé vidéo when you make that tools ?I i would like to know if it's possible to use the TIG weding to put some aluminium on thé damage area instead of screwing the half aluminium cercle like you did on this vidéo.
Sorry i'm a french guy trying to write english from memory.
Thanks you Paul! ✌️
new head is 800 without anything just bare cast
How many hours were on this engine?
80

Hi mate could i please get your email so i can pay you to do mine? Really need this done for my sxf350 2017 thanks
If you were near me . .huhuhu
People throw around the term "I'm an engineer" quite loosely. But what I just watched in my opinion is what I would describe as an engineer, at it's finest.
Thank you .
Youu just did throw it around
He may have machining skills, but he is nowhere close to a mechanical engineer, or any sort of engineer.
@@psiturbo I'm assuming you invented the space rocket then?
@@_Hangman wrong, AGAIN!
engineer, LOL!
C'mmon, you got the mic, tell us all the formulas, equations he utilized during this process.
Seriously, is not that difficult, the machine is doing it all.
I invented the BS Machine, and I called it Marc 2000...😂😂😂💥
👏👏👌🇳🇴
How many hours did that take? How much per hour is your labor worth? How much did material cost? Willing to bet you could buy the head new for less and not worry if 1 of those screws is gonna come out. Cool idea but only if you have a machine shop and no other option.
*woosh* - the art of machining going over your head. Obviously this gentleman loves his work, has mastered his trade and takes great pride and satisfaction in saving an otherwise scrap piece of metal. It has nothing to do with cost or time.
@@grieks im my world it does. I totally get it when a part is no longer available, but most of us don't have a mill, lathe, and all the other machines to do that work or the time. Time is money in my world.
@@glimmerman4hm
It's not about this being realistic for you, or the most cost effective or time saving fix.
Of course the average person doesn't have a lathe, or milling machine or the time. Of course the average person would just buy a new head. For the average person, time is money.
This gentleman isn't the average person, he's showing us his craft. Just enjoy it :)
@@grieks i did enjoy it, im just being the realist.
I'll take Paul X's version of real any day 👍
There's hardly any bushing where the screw is, a weak point.
Don't worry it work well.
2/3 of the screw is in the lubrication groove
@@PaulXchannel I would say it's a design flaw from the factory.
@@Angelina-xj5zd This is a user error.
A little oil.
IT SEEMS A GOOD JOB, BUT IT ISN'T, THE TREES ARE ECCENTRIC AND THE PROBLEM THAT CAUSED EVERYTHING IS NOT SOLVED, BLESSINGS
