I think the main point of this video is to teach beginners and people who want to do it at home with whatever they have around. Otherwise, for Mr.Wolf, this stuff is a piece of cake. I like it ❤
Why did you heat the guides before driving them out? The aluminium has a higher rate of expansion than steel. If you use a punch with a pilot it acts as a heat sink further reduces the interference fit.
Hi، Since during installation it's secured using the same process, heating the cylinder head slightly expands the space, allowing it to come out easily. Otherwise, it would definitely break.🙏
@@MrWolfDiy Es wurde nicht gezeigt, dass der inner Luftzug durch die Ventilführung nach dem Erwärmen diese schneller abkühlt, als das Aluminium Wärme in die Ventilführung nachliefern kann. Da das Werkzeug zum Austreiben ebenfalls sehr kalt ist, lässt sich die Ventilführung bei dieser Art von Zylinderköpfen leicht und problemlos damit entfernen, weil die Ventilführung dadurch etwas schneller schrumpft als der Aluminiumzylinderkopf selbst.
Oh how I wish this idea, removing valve springs had cropped up 50years ago .! I hate the "G" clamp tool - the lever tool I'm sure would work on other heads.
You're supposed to heat the head, not the guide, lol. If you heat the quide... it will expand and get tighter, you want the head to expand so the press-fit gets looser, smh 🤦
right, but I heated the cylinder head for 10 minutes. Cut that part from the video to keep it short. Just needs heat to loosen up and come out with light taps. Same deal when putting it back... thanks for watching 🙏
Dont follow this heating method. Its wrong. If you heat the nearby area the pressfit increases onto the guide! Use an old bench owen and put the whole head in for an hour at 150_200 degrees celsius. If the guide still is hard to drive out heat it more. Didnt see a reaming process to the new guides! Missed the cutting of new valve seat also. You cant use abrasives only. And you dont use a drilling machine for that either. It should be a light reciprokating movement with changes of the angular position..

Thank you showing this video very informative.
Glad it was helpful!🙏

I like your desi jugad❤❤❤❤truely Hard-core Engineer by birth.....
If you get a socket with an extension place over top of the valve hit with hammer it pops the collets out . Works on motorbikes and cars
Hi. I use to chill the guides before put them into the hot cylinder head..
It's easy to me...
Great tip!
Nice! Love the tool - looks easy to make and seemed to work like a charm
Agreed 👍
I came hear and it’s everything I need to know .. great job by the way ..
"I'm glad it was helpful for you."
Thanks 🙏
I really enjoyed it❤❤❤❤❤❤❤
Nice work
Thank you! Cheers!
Id you want to destroy an engine!

Hi, I use to chill the guides before put again into hot cylinder head.
The best🎉
Thanks 🙏
Very nice, neat and effective..
Nice job, keep up..
My first time of fitting value guide I broke like 3 😂
Me to 😅
Effectively neat and very nice.
Where can i find "Rapido" valve kit ❤
hey come up with a thing you can do a cdi with rev limiter can't find anyone who made a video on it on youtube
Ye Piece of cake, In the next videos.
This was the best tutorial I have ever seen👋
Perfect 👍
TNX
You obviously have, like the maker of this video, no clue about engines!

Stay humble , we all in this bowl together brother ✌️

Exactly! Just like when people heat a bolt they’re trying to take out. You’re supposed to heat the area around it!
Your supposed to ask questions before making assumptions 🎉
Couldn't you just put the guides in the freezer overnight it's a trick they do with putting in sleeves in diesel engines
Cooling the guide metal causes it to contract, while heating the cylinder head causes it to expand. Both methods can be used together.🙏
Really need some dry ice , a normal freezer doesn't do much for contraction except allow a part to not warm up as quick.
Very good - music is annoying, though
No entanto o resto está errado
Those are called valve seats not washers
👍

Ja, das Ziel des Videos ist es, Amateuren die Möglichkeit zu geben, ihre Grundkenntnisse zu überprüfen.
@Reiner_Markenfreund excellent 👍

A co z oringiem ? Nie spalił się. Lepiej było prowadnicę zamrozić.
After removing the old guide, the O-ring is replaced
only one this is wrong ....u r using used engine oil for
Thanks for your input.❤️🙏
