There are many ways, but generally it is possible with a bearing puller.
Yes, but doing it properly might rob you of the opportunity to waste time and most likely ruine the BB too
Nice job! I never had problems like that, but it's good to know. 👍
Te recomiendo que consigas un extractor de brazo pitman de camioneta, el extractor agarra la biela por detrás y por el frente vas apretando el tornillo igual que el extractor de bielas para bicicleta, con eso no dañas nada, ni andas haciendo malabares qué te pueden ocasionar un accidente
Excelente vídeo! Por coincidência, ocorreu o mesmo em minha GT Avalanche 3.0! 🤣🤣🤣
クランクを取り外した理由がBBの交換であればBB軸を鋸で切断します。
cara, eu tirava pedivela sem extrator em minutos apenas batendo com um pedaço de madeira, e fiz muitas vezes isso
Excelente trabalho. Perfeito
I have even drilled out the bottom bracket spindle on one occasion as the cranks were steel..
Miałem to samo, lewa strona poszła ściągaczem warsztatowym bo miałem obrobiony gwint, prawa strona kątówką, suport musiałem dać do mechanika rowerowego, wyciągnął ramieniem 1.5m, rower 30letni lub starszy, wszystko wygląda fajnie na filmach 😊
Ciekawa historia, masz szczęście, że suport nie poluzował się razem z gwintami
@@NiceBikeService na szczęście wyszło i mufa jest cała, rdzę potraktowałem neitralizatorem rdzy, założyłem suport Shimano un /300, piękne się wkręcił, czuć jakość, jednak warto czasami dołożyć do czegoś lepszego, korba już założona, teraz składam resztę do kupy. Pozdrawiam! Fajny kanał 👍
Eu já removi várias vezes pé de vela com esse problema mas bem mas simples e ainda usei o pé de vela novamente peguei um metal e uma martelo e bati por trás dele e pronto
has anyone tried the UNIOR tapered puller?
Please give me a link to it. I can't buy it in my country.
Que trabalho que deu amigo Caçador SC
Já tirei com um saca polia de dois braços, muito mais fácil que dessa forma.
Pensei o mesmo.
Si vas a destruir la biela con la rosca dañada entonces es mejor cortarlo con un disco de corte de metal por un lado del cuadradillo
Nice 👍
VAR ha il kit per rifare i filetti delle pedivelle
Mano! Nessa aí eu vou te dar uma dica, usa um saca polia, vc vai retirar esse pé de vela Rapidão.👍👍👍
La mia esta barrido tambien solo que no puedo hacer eso no tengo plata para comprar uno nuevo
J'ai eu le même problème sur mon vtt avec le même pédalier suntour.
Le filetage des manivelles en aluminium est assez fragile surtout que l'arrache est lui en acier.
Alors j' ai fabriqué un arrache 2 branches universel type arrache roulements ou moyeux avec du fer plat de 5mm et une tige filetée de 10 mm. J'ai pu démonter les deux manivelles sans problème et sans les abîmées. Si vous n'êtes pas bricoleur, il suffit d' acheter un arrache moyeux 2 branches (2 branches important pas 3). Un petit truc à savoir, mettez une visse btr de 6 dans le trou fileté du pédalier. Cela va permettre à la tige de l'extracteur de prendre appui sur la tête de cette visse btr.
Ok merci pour ton conseil c est cool👍😉
Lo he sacado con un cincel martillo... se le dan golpes por la parte de adentro al mango del pedal...en 10 segundos sale.
An angle grinder with a tungsten reinforced disc is easiest and very fast , 5 seconds .
Es gibt einen speziellen Satz Werkzeug zum ausreiben des gewindes, danach wird ein größeres gewinde geschnitten und mit einem größeren Abzieher abgezogen, somit bleibt die kurbel erhalten.
Dremel, Trennscheibe und 2 saubere Schnitte oben und unten in die Kurbel, die Kurbel ist sowieso Schrott.
will u use the crank arm again?
No, this crank will be used for metal recycling
This is what happens when you Don't look after your bike
Usa un saca polea o saca rulemanes .de esa forma dañas el marco .
Ben dis donc, moi, ça m'est arrivé mais j'ai trouvé un extracteur à vis et je mets une tige solide du diamètre dans le trou de la vis de l'axe de pédalier pour prendre appui et c'est parti mon quiqui sans aucun dommage et j'ai même remonté la pédale et je peux la démonter à nouveau avec le même outil. Il existe tous formats d'extracteurs de moyeux à vis et celui que j'ai s'adapte à une grande fourchette de diamètres et je peux aussi bien démonter la pédale du coté pédalier et l'autre CQFD pour infos.
A mi me paso eso sólo tube que pedaliar por dos dia y salió
@@NiceBikeService compre un brazo no igual que el otro pero casi voy a comprar un juego de triplato shimano original
The leverage on the bar at about 9:20 could have put the frame out of alignment .
The pilot hole locations could have been more accurate . I would use a milling machine with a block to sit the bicycle on .
Qual a melhor chave para remover catraca roda livre em casa uns fala que é chave de grifo outros fala chave inglesa e outros a própria chave de boca agora to em dúvida por que é um serviço caseiro pra fazer em casa
@@NiceBikeService martelo e prego e pra quem desmonta catraca ❌
minha intenção e remover a catraca e nao desmontar ela😪 a chave de catraca eu ja tenho o que eu não tenho e a
((((chave de grifo ou inglesa))))) pra fazer alavanca ✅
A WORN CRANK REMOVER WAS USED AT THE BEGINNING , BIG MISTAKE .
Dwu lub trzy-ramiennym ściągaczem, powinno pójść, szybko i bez zabawy.
Mycket ska man se men detta är väl överarbetat det finns bättre sätt!
Tack för din feedback! 😘
mission accomplished
🚲😃👍
Um simples saca polia de dois braços resolveria
@@NiceBikeService mano tem lá no canal do silvan da uma olhadinha lá mas eu mesmo já uso a muito tempo essa técnica aqui Na minha oficina
Asu que tan difícil fue de extraer la biela 😏
bearing extractor
it doesn't work
Kun pölkupyörän koipi kierre kuluu , ei tarvitse polta tai poraus vain saha yhden viiva suoran ulko puolella . Niin hae pois , se on helpoa .
クランクアーム 叩くと取れますよ
TUNGSTEN CARBIDE DRILL BITS TO THE RESCUE .
Cosa c'entra con il fatto che non cambia marcia
pulling attachment will be better
Gdzie masz diaxa?
@@NiceBikeService no szlifierkę kątową
Much easier is to cut the crank arm with angle grinder, cranks and suport itself are useless either way ;)
all methods are good, the main thing is the result))))
nao precisava disso tudo era so tirar o parafuso e usar uma marreta de borracha pra bater ate sair sentido de dentro pra fora
@@NiceBikeService esquenta com o maçarico o parafuso que ele solta de boa aqui na minha bicicletaria fazemos muito isso porque essa rosca vive espanando
disqueuse dremel me semble plus pratique 😉
@@NiceBikeService ou une vraie disqueuse mais faut etre très précis 😁
If you'd have removed the bolts and rode for a few weeks, it will come off 😂. But it is a bad way too
Or they would have stuck even more 😸😹
@@NiceBikeService lol
😖😱hello, passing handyman, I saw your video that I did not appreciate, how you used to extract the pedal box when you heat the aluminum, the door of the axle, it will swell with the temperature, it is dedicated to you, you are a beginner mechanic, for you help use a bearing extractor or an electric dremel to cut in both sides cedr simpler than that thank you
@@NiceBikeService hello the idea is to extract the pedalboard so your several extractor that you can find on me either two eighth notes or three you have the choice a small one that will do it besides me it's been a week I had the same problem as you so I used a small one extractor on the other hand you put a small spacer between the screw of the extractor and the hollow of the pedal box so as not to damage the spinning here is good luck
My bike mechanic used a “fork”. He inserted this thing between the crank and the frame. It has the trapeze shape, so after the hammer hit the broken crank removes easily
@@NiceBikeService no, he puts a spacer not to damage it
Болт попустив і мені вистачило покрутити педалями, аж раптом до сусідньої вулиці, відчув що шатун знявся ))) вернувся викрутив болт - шатун відпав )) і не потрібно стільки часу і сміття ))
I would have just used a Dremel Tool and attacked the crank arm from the outside of the arms making two cuts 180 degrees from each other. The arms would have fallen right off the spindle.

*ASK YOUR QUESTIONS*
👇👇👇
Are you going to reuse the crank arm?
If I were you, I'd remove the crank arm with the bearing pullers
Todo ese trabajo para quitar unas bielas???
Y por qué no conseguir un extractor de bielas dañadas con rosca cónica???🤷♂️
No daña las bielas al sacarlas, usa la herramienta adecuada y se deja de improvisar mientras facilita su trabajo🤔
Why not cut it with hacksaw ? Much faster than that.
用砂輪機切
it is much more easier to use a bearing puller.... that was i used....
all you need is separating fork
thanks for the advice ! 😘
Tu chauffes et ça sort tout seul !
Tu chauffés la manivelle avec un chalumeau ou autre chose qui chauffe pour dilater l'alu autour du carré de l'axe et ça sort tranquille ,c'est qu'on fait en atelier .vu le filetage se barre ta manivelle ne doit plus être top !
My god!!!!! All you had to do was hit the crank arm with a rubber mallet, it would of came off because the bolt was clearly already removed.
Körmös lehúzhatót nem ismerik????
bastava usare il flessibile
Where you from? 🧐
Юкрейн, на сколько я понял из прошлых видосов.
He is Ukrainian
Oder kurbel erhitzen und von innen runterschlagen ganz einfach.
Lấy vam hai chấu công ra
工具はいりませんよ
そのまま走れば緩みます ただし交通量の多いところはクランクが外れて落車の危険があるので注意 （左だと５～１０Kｍ）
Wie ale w którym kościele dzwoni
да разрежь ты его болгаркой
LOL good ol GT Aggressor Pro
still: not a walk in the park....
Триндец какой-то! Кто в себе - не делайте так
こうなってはもうこのクランクは駄目なので強引に二つ爪のプーラーを引っ掛けて外しましょう。
そうそう、実際コッタレスクランク抜きと理屈はおんなじですからね。
わたしも同じようにネジ山なめたクランクをプーラーで抜いたことあります。
爪をうまく引っ掛けるのが難しいんですけどね・・・
era mas facil usar una amoladora...
@@NiceBikeService una amoladora con un disco de corte, le hacías un corte a la biela y salía sin mucho sudor. Torcer la biela en mi opinión afecta un poco la caja de pedalier y bueno creo que es más sencillo cortar la biela.
先生これは俺には無理です。難しい
Kkkkkkkkkkkk
Купити нові шатуни
@@NiceBikeService 😆
Маєте рацію)
Crows foot
Realy ? This is a crime 🤣🤣
I used hammer
✊
There are special repair tools for repairing the threads...
U cut a larger format thread and then use the puller that comes with the kit ...
This is amateuristic imo
Was für ein Schwachsinn! Da nimmt man einen 3-Klauen KFZ- Abzieher, wenn das Gewinde herausgerissen ist!
Cringe, cut cranks using gringer way more faster
😹
bikes are worth all this? its just a bike just hammer it out
To ride comfortably and for a long time, you need to take care of your bike
malisimo sistema.
My threads are fine and even brute force, even STANDING on my spanner on my extraction tool. AND STILL… crank arm REFUSED to budge. My explanation? Mine must be welded in. You literally need three people to do it. One to hold the bike down. One to hold the crank arm. And one to operate the tool. I M P O S S I B L E. hardest thing I’ve ever had to do in my life. Id say these “how to” videos are fake
Bez sensu, szkoda tyle zachodu. Ja bym brzeszczotem przeciął kolbę i po kłopocie szybko i bez grzebania.
@@NiceBikeService Tak piłą szablastą
Większej bzdury nie widziałem po co to wiercić jeszcze kolejność najpierw duże potem małe wiertło widać że nigdy tego nie robił bo robi się odwrotnie. A w tym przypadku korba i tak śmietnik więc wystarczyło ja fleksem naciąć i po krzyku.
I always use 3 arm puller, without damaging anything very easy to remove the crankset. Your method is useless.
This was a boring video...🙄
You can't please everyone.
How old are you?
@NiceBikeService it's not really a matter of age...although it was very time consuming...lol !
It was just boring...I didn't say it scuked..I'll watch it again when I get back from a ride..maybe then my attitude will be better..👍🏻
😴😴😴😴😴😴
😺
Та це х...болгарка для цього є.
Usa um saca polia, é mais fácil e não detona o pé de vela.
